Good evening, everyone. 00:01:42.519 --> 00:01:46.680 It's time for HamTalk Live. Yeah, it really is. 00:01:46.859 --> 00:01:48.920 And it's Wednesday, and it's eight o 'clock, 00:01:49.959 --> 00:01:54.180 and that's not normal. But it's just for this 00:01:54.180 --> 00:01:57.780 week. But it is time for another episode of HamTalk 00:01:57.780 --> 00:02:01.560 Live. It's number 53, Heard Island De -Expedition 00:02:01.560 --> 00:02:05.400 and Science Research with Dr. Bill Mitchell, 00:02:05.480 --> 00:02:10.120 A -E -0 -E -E. Recorded live Wednesday, February 00:02:10.120 --> 00:02:15.960 22nd, 2017. I'm your host Neil Rapp, WB9VPG. 00:02:16.479 --> 00:02:18.860 Thanks for tuning in to this episode of HamTalk 00:02:18.860 --> 00:02:21.599 Live. Tonight we're joined by Dr. Bill Mitchell, 00:02:21.840 --> 00:02:25.319 AE0EE, who went on the Heard Island De -Expedition 00:02:25.319 --> 00:02:28.860 and also did scientific research while he was 00:02:28.860 --> 00:02:31.340 there. So we're going to talk a little bit about 00:02:31.340 --> 00:02:33.400 the De -Expedition, but we're going to talk some 00:02:33.400 --> 00:02:37.020 science tonight. and we'll take your calls live 00:02:37.020 --> 00:02:41.979 in just a few minutes. Last week, Fred Reganiter, 00:02:42.159 --> 00:02:45.240 K4IU, was here to talk about DXing and operating 00:02:45.240 --> 00:02:48.020 from the canal zone and other countries. And 00:02:48.020 --> 00:02:50.180 if you missed the show, you can listen anytime 00:02:50.180 --> 00:02:53.919 at HamTalkLive .com or on iTunes, Stitcher, Google 00:02:53.919 --> 00:02:58.020 Play, TuneIn, SoundCloud or YouTube. And yeah, 00:02:58.039 --> 00:03:00.039 tonight we're coming to you a day and an hour 00:03:00.039 --> 00:03:02.659 earlier because I have to announce a basketball 00:03:02.659 --> 00:03:06.639 game tomorrow night at school and it only happens 00:03:06.639 --> 00:03:12.750 once every other year on Thursday and so... I 00:03:12.750 --> 00:03:16.789 have to be there for that. So we moved the show 00:03:16.789 --> 00:03:20.090 up a day and up an hour so we don't conflict 00:03:20.090 --> 00:03:24.069 with the Ham Nation people. We'll be done in 00:03:24.069 --> 00:03:26.669 plenty of time if you want to switch over and 00:03:26.669 --> 00:03:31.389 watch that live. So next week we'll be back on 00:03:31.389 --> 00:03:35.849 our usual Thursday at 9 p .m. Eastern schedule. 00:03:36.699 --> 00:03:39.159 Tonight also marks the beginning of year number 00:03:39.159 --> 00:03:42.520 two for HamTalk Live.

Dr. Bill 00:06:42.819 --> 00:06:48.600 Mitchell AE0EE was a radio operator on the VK0EK 00:06:48.839 --> 00:06:51.600 Heard Island De -Expedition during March and 00:06:51.600 --> 00:06:56.160 April of 2016. He was originally licensed in 00:06:56.160 --> 00:07:01.339 December of 2012 in California as AG6RB and then 00:07:01.339 --> 00:07:06.720 took the call sign AE0EE in July of 2014. Bill 00:07:06.720 --> 00:07:10.240 is most often found on HF and enjoys a mix of 00:07:10.240 --> 00:07:13.740 CW and sideband, occasionally some digital mode, 00:07:13.779 --> 00:07:17.540 satellite and meteor scatter. And for the first 00:07:17.540 --> 00:07:20.699 18 months, after he was licensed he primarily 00:07:20.699 --> 00:07:25.139 operated the club station W6BB at the University 00:07:25.139 --> 00:07:28.779 of California Berkeley. Because he lives in an 00:07:28.779 --> 00:07:31.220 apartment he does a lot of portable operations 00:07:31.220 --> 00:07:35.279 and when not on the radio Bill enjoys doing and 00:07:35.279 --> 00:07:39.759 teaching science. He has a BA in chemistry from 00:07:39.759 --> 00:07:42.759 Carlton College and a PhD in chemistry from UC 00:07:42.759 --> 00:07:47.720 Berkeley and while his primary focus is physical 00:07:47.720 --> 00:07:51.100 and analytical chemistry. His research has been 00:07:51.100 --> 00:07:54.600 broad spanning from organometallic synthesis, 00:07:54.899 --> 00:07:58.120 kinetics, polymers to photon photochemistry, 00:07:58.540 --> 00:08:02.339 atmospheric chemistry and physics, geochemistry 00:08:02.339 --> 00:08:06.160 and geology and his dissertation focused on high 00:08:06.160 --> 00:08:10.920 precision uranium lead dating. And the scary 00:08:10.920 --> 00:08:15.500 thing is I know what all that meant. Good evening, 00:08:15.500 --> 00:08:18.620 Bill. Thank you for coming on the show. Good 00:08:18.620 --> 00:08:21.019 evening. Thanks for having me and congratulations 00:08:21.019 --> 00:08:25.800 on the anniversary of the show. Oh, thank you. 00:08:25.819 --> 00:08:29.060 Yeah. It's been, uh, been a lot of fun and, um, 00:08:29.060 --> 00:08:32.379 and that's why I started doing it. So, uh, hopefully, 00:08:32.399 --> 00:08:35.519 uh, it'll, it'll keep being that way and, and 00:08:35.519 --> 00:08:39.460 keep on going. Well, uh, we want you to talk 00:08:39.460 --> 00:08:44.419 about herd Island tonight, uh, which, um, It's 00:08:44.419 --> 00:08:48.399 not quite been a year since since that happened 00:08:48.399 --> 00:08:51.500 And tell us a little bit about the trip and what 00:08:51.500 --> 00:08:55.840 you hope to accomplish by going on that the expedition 00:08:55.840 --> 00:09:01.919 Sure, thanks Neil Yeah, so the I learned about 00:09:01.919 --> 00:09:09.019 the expedition about three years ago and Went 00:09:09.019 --> 00:09:13.080 to my local amateur radio club meeting at the 00:09:12.960 --> 00:09:17.179 urging of one of my mentors at the time and the 00:09:17.179 --> 00:09:20.139 expedition leader for Heard Island was talking 00:09:20.139 --> 00:09:24.139 about an expedition to Clipperton Island that 00:09:24.139 --> 00:09:27.360 he'd made previously and started talking about 00:09:27.360 --> 00:09:30.019 how he wanted to go to Heard Island and he talked 00:09:30.019 --> 00:09:34.039 about the volcano there that was covered in glaciers 00:09:34.039 --> 00:09:36.340 and at that he'd already gotten my attention. 00:09:37.659 --> 00:09:40.940 He said something about four species of penguins 00:09:40.940 --> 00:09:44.230 that live on the island and that really got going. 00:09:44.350 --> 00:09:46.529 And then he said, oh, and it's also one of the 00:09:46.529 --> 00:09:52.149 top 10 most wanted territories on earth for amateur 00:09:52.149 --> 00:09:55.830 radio. And I said, well, that sounds good too. 00:09:57.610 --> 00:10:01.029 So thought long and hard about whether I wanted 00:10:01.029 --> 00:10:06.169 to, was able to join. And after about a year 00:10:06.169 --> 00:10:10.889 of deliberation, ended up saying, yes, I really 00:10:10.889 --> 00:10:18.649 want to do this. So it was a big undertaking. 00:10:19.389 --> 00:10:21.690 Heard Island, for those of you who aren't aware, 00:10:21.850 --> 00:10:26.350 is a sub -Antarctic island in the extreme southern 00:10:26.350 --> 00:10:31.389 Indian Ocean, about halfway between South Africa 00:10:31.389 --> 00:10:34.009 and Australia, but quite a bit further south. 00:10:35.929 --> 00:10:39.269 It was a 12 -day voyage at sea to get to the 00:10:39.269 --> 00:10:43.090 island. from Cape Town and then another 10 days 00:10:43.090 --> 00:10:47.870 after we left to continue on to Fremantle and 00:10:47.870 --> 00:10:52.090 Perth in Western Australia. So there were a lot 00:10:52.090 --> 00:10:54.929 of different scientific things to do while we 00:10:54.929 --> 00:10:59.889 were on the expedition. One of the ones that 00:10:59.889 --> 00:11:04.450 I got into as an amateur birder is looking at 00:11:04.450 --> 00:11:07.990 some of the southern ocean seabirds. I've participated 00:11:07.990 --> 00:11:13.460 in the e -bird citizen science project where 00:11:13.460 --> 00:11:16.259 birders will go out, they'll observe and count 00:11:16.259 --> 00:11:18.840 how many birds of different species they find, 00:11:19.259 --> 00:11:22.080 and then they'll submit their logs into a centralized 00:11:22.080 --> 00:11:25.419 database that's used for doing population research. 00:11:25.980 --> 00:11:28.340 It's similar to the amateur radio logbook of 00:11:28.340 --> 00:11:32.700 the world, except it's for birds. We also deployed 00:11:32.700 --> 00:11:37.580 some buoys, both surface drifting and some diving 00:11:37.580 --> 00:11:43.299 buoys for getting a number of different parameters 00:11:43.299 --> 00:11:47.879 from the ocean. I took high resolution panoramic 00:11:47.879 --> 00:11:50.440 images of some of the geologic features on the 00:11:50.440 --> 00:11:54.659 island. We sampled rocks and soil and water for 00:11:54.659 --> 00:11:58.759 a number of environmental science projects. And 00:11:58.759 --> 00:12:01.879 we also did a little bit of study of some high 00:12:01.879 --> 00:12:05.039 frequency electromagnetic propagation, which 00:12:05.039 --> 00:12:08.470 is what a lot of people contributed financial 00:12:08.470 --> 00:12:12.210 support to have us do. So that's a little bit 00:12:12.210 --> 00:12:17.590 of some of the science that we did. And get a 00:12:17.590 --> 00:12:23.830 few QSLs sent out afterwards. Yeah, there were 00:12:23.830 --> 00:12:27.610 a few postcards to send confirming contact expedition. 00:12:27.750 --> 00:12:32.350 That's true. Yeah, just a few. Well, I teach 00:12:32.350 --> 00:12:35.970 chemistry for a living and while physical chemistry 00:12:35.970 --> 00:12:41.299 still still haunts me. Analytical chemistry was 00:12:41.299 --> 00:12:43.519 something that I really got into because there 00:12:43.519 --> 00:12:47.720 were so many connections with ham radio because 00:12:47.950 --> 00:12:53.429 using waves to analyze chemicals just made total 00:12:53.429 --> 00:12:56.970 sense to me. And so when we got to the electronics 00:12:56.970 --> 00:12:59.210 part, I was like, yeah, yeah, yeah, yeah, I know 00:12:59.210 --> 00:13:04.009 this stuff. This is great stuff. And did some 00:13:04.009 --> 00:13:09.389 research on some NMR and things like that. But 00:13:09.389 --> 00:13:13.330 most people listening tonight probably aren't. 00:13:13.370 --> 00:13:16.230 chemists. So while I want to get into that a 00:13:16.230 --> 00:13:18.490 little bit, why don't you explain a little bit 00:13:18.490 --> 00:13:23.210 about some of the analysis that you've been able 00:13:23.210 --> 00:13:28.690 to do with the samples that you brought back 00:13:28.690 --> 00:13:33.929 from Heard Island? Okay, well I've actually been 00:13:33.929 --> 00:13:37.009 relatively removed from the samples that were 00:13:37.009 --> 00:13:40.090 brought back, but I do know that one of the projects 00:13:40.090 --> 00:13:44.970 that was being worked on is figuring out how 00:13:44.970 --> 00:13:48.129 old some of the lava flows are on Heard Island. 00:13:48.929 --> 00:13:51.990 Many of the researchers and geologists who've 00:13:51.990 --> 00:13:55.049 been to the island previously have remarked that 00:13:55.049 --> 00:14:00.090 the flows look recent. And even for a geologist, 00:14:00.330 --> 00:14:03.769 recent is a pretty broad definition. For people 00:14:03.769 --> 00:14:07.570 who study really old things, a million years 00:14:07.570 --> 00:14:11.690 might be really recent. it might even be older 00:14:11.690 --> 00:14:14.009 than millions or millions of years that people 00:14:14.009 --> 00:14:19.970 would consider recent. So because so many scientists 00:14:19.970 --> 00:14:22.870 have remarked on how it looks recent but we have 00:14:22.870 --> 00:14:26.470 absolutely no numbers for recent, one of our 00:14:26.470 --> 00:14:29.389 goals was to collect some samples that could 00:14:29.389 --> 00:14:33.210 be used to actually determine an age for those 00:14:33.210 --> 00:14:38.990 recent lava flows which are expected to be somewhere 00:14:38.990 --> 00:14:44.629 around 10 ,000 years or maybe younger. And the 00:14:44.629 --> 00:14:48.809 way that that ends up getting done is that the 00:14:48.809 --> 00:14:53.169 scientists will look for radiogenic, or not radiogenic, 00:14:53.409 --> 00:14:58.610 cosmogenic isotopes in the rock. So elements 00:14:58.610 --> 00:15:01.330 with a specific number of protons and neutrons 00:15:01.330 --> 00:15:05.049 in them that have come because of cosmic radiation 00:15:05.049 --> 00:15:08.080 hitting that rock. When the lava flow comes out 00:15:08.080 --> 00:15:10.799 and they're exposed at the surface that radiation 00:15:10.799 --> 00:15:14.460 can cause these changes in the rock and we can 00:15:14.460 --> 00:15:17.639 then bring that back to the lab and measure it. 00:15:18.139 --> 00:15:21.399 And so we grabbed a bunch of samples and those 00:15:21.399 --> 00:15:27.460 are now in Tasmania under analysis. Very good 00:15:27.460 --> 00:15:33.120 and you mentioned the the bird logbook, if you 00:15:33.120 --> 00:15:38.720 will, on that. What about the buoys and some 00:15:38.720 --> 00:15:47.419 of the studies from the RF that was being generated 00:15:47.419 --> 00:15:52.179 there? Tell us a little bit about what analysis 00:15:52.179 --> 00:15:55.539 has been done on that and any of your findings 00:15:55.539 --> 00:16:00.539 that you've been able to get so far. Sure. So 00:16:00.539 --> 00:16:04.059 we deployed two types of buoys from the ship 00:16:04.059 --> 00:16:08.779 because there's a lot of open ocean in the southern 00:16:08.779 --> 00:16:14.080 ocean that isn't very well monitored. It's not 00:16:14.080 --> 00:16:16.779 like on land where we have lots of weather stations. 00:16:17.419 --> 00:16:20.720 Out in the open ocean, there's not much going 00:16:20.720 --> 00:16:25.879 on. So in order to help weather forecasting and 00:16:25.879 --> 00:16:29.509 understanding how ocean circulation works, we 00:16:29.509 --> 00:16:33.250 deployed two different types of buoys. One type 00:16:33.250 --> 00:16:39.250 is a surface buoy from NOAA, and those track 00:16:39.250 --> 00:16:42.590 the sea surface temperature, and they also send 00:16:42.590 --> 00:16:47.610 their position back via a satellite link. And 00:16:47.610 --> 00:16:50.309 so those are used to monitor the surface currents 00:16:50.309 --> 00:16:54.309 in the oceans around the world. And some of our 00:16:54.309 --> 00:16:58.620 buoys have moved I think upwards of 2 ,500 miles 00:16:58.620 --> 00:17:02.960 from when we left them in the water. The other 00:17:02.960 --> 00:17:05.599 type of buoy that we have are what are called 00:17:05.599 --> 00:17:08.559 Argo buoys, which are diving buoys. They spend 00:17:08.559 --> 00:17:11.660 most of their time about one kilometer under 00:17:11.660 --> 00:17:17.119 the water surface drifting along. But every 10 00:17:17.119 --> 00:17:21.359 days, they'll drop down to 2 ,000 meters depth, 00:17:21.839 --> 00:17:25.220 and they'll then measure the conductivity, the 00:17:25.220 --> 00:17:27.519 temperature, and the depth all the way up to 00:17:27.519 --> 00:17:33.259 the surface. And that allows researchers some 00:17:33.259 --> 00:17:38.079 insights into how the temperature and salinity 00:17:38.079 --> 00:17:41.660 change in sort of a three -dimensional view over 00:17:41.660 --> 00:17:45.400 the ocean. Originally, that was of particular 00:17:45.400 --> 00:17:49.000 importance for hiding submarines, but it's also 00:17:49.000 --> 00:17:53.609 useful to see where water is mixing. how the 00:17:53.609 --> 00:17:58.730 oceans are changing in our current climate. And 00:17:58.730 --> 00:18:02.410 I have a little bit of information on some of 00:18:02.410 --> 00:18:08.609 those Argo diving buoys posted on my blog inquisitiverockhopper 00:18:08.609 --> 00:18:14.349 .wordpress .com. Very good and we'll send that 00:18:14.349 --> 00:18:18.410 out a link to that too so people can find that 00:18:18.410 --> 00:18:24.450 easily. uh... and then uh... the rf yeah uh... 00:18:24.450 --> 00:18:28.329 the rf was a a fun part uh... it's incredible 00:18:28.329 --> 00:18:31.769 being at the uh... uh... far end of uh... very 00:18:31.769 --> 00:18:38.309 wanted uh... very wanted uh... territory uh... 00:18:38.309 --> 00:18:40.210 there were a lot of people who wanted to make 00:18:40.210 --> 00:18:43.630 contact with us uh... we made uh... over seventy 00:18:43.630 --> 00:18:50.259 five thousand contacts uh... both on voice, mostly 00:18:50.259 --> 00:18:55.900 on Morse code, and a few on radio teletype. And 00:18:55.900 --> 00:19:01.599 that was with all continents of the world. We 00:19:01.599 --> 00:19:06.119 even had one contact with one of the Antarctic 00:19:06.119 --> 00:19:10.599 research bases, which was a fun contact to make. 00:19:10.960 --> 00:19:13.779 We ended up having both the... our expedition 00:19:13.779 --> 00:19:16.819 leader and the station manager of that station 00:19:16.819 --> 00:19:19.880 having a short conversation with each other, 00:19:20.099 --> 00:19:25.880 which was pretty memorable. Very good. Good deal. 00:19:26.980 --> 00:19:32.559 So how did you find time to do all the research 00:19:32.559 --> 00:19:37.299 and keep up with your shifts on the expedition 00:19:37.299 --> 00:19:41.630 and keep everything running? Yeah, well, I didn't 00:19:41.630 --> 00:19:45.269 get a lot of sleep is the short answer. But the 00:19:45.269 --> 00:19:49.849 longer answer is that it was possible because 00:19:49.849 --> 00:19:54.049 we spent months and years planning for the expedition. 00:19:55.210 --> 00:20:00.269 So I joined about 18 months before we departed. 00:20:00.369 --> 00:20:04.269 So I joined in September of 2014. And even by 00:20:04.269 --> 00:20:07.509 that time, I'd been thinking about it and reading 00:20:07.509 --> 00:20:12.480 about it. for the better part of a year. After 00:20:12.480 --> 00:20:15.980 that additional 18 months of planning and research, 00:20:16.579 --> 00:20:20.059 much of the expedition was choreographed and 00:20:20.059 --> 00:20:23.160 prioritized. So we had procedures written out 00:20:23.160 --> 00:20:26.339 that even a tired, frustrated expedition member 00:20:26.339 --> 00:20:30.859 could carry out and they could use the checklist 00:20:30.859 --> 00:20:33.220 so that they would get things done right and 00:20:33.220 --> 00:20:36.279 get things done efficiently because you don't 00:20:36.279 --> 00:20:39.519 want to waste time dealing with stupid problems 00:20:39.519 --> 00:20:43.759 that if you would manage to do if you were more 00:20:43.759 --> 00:20:46.460 awake or if you and we didn't want to have to 00:20:46.460 --> 00:20:48.579 think about anything that we didn't need to have 00:20:48.579 --> 00:20:52.640 to think about on the island and it was a challenge 00:20:52.640 --> 00:20:55.619 at times to get everything done. We did have 00:20:55.619 --> 00:21:00.279 to sort of prioritize which things get done and 00:21:00.279 --> 00:21:03.480 which things don't and I would have loved to 00:21:03.480 --> 00:21:06.849 do more of the gigapan images and to get more 00:21:06.849 --> 00:21:10.650 birding in on the island and take more pictures 00:21:10.650 --> 00:21:14.289 but there were only so many hours in the day 00:21:14.289 --> 00:21:17.869 and the generators needed refilling and the antennas 00:21:17.869 --> 00:21:23.710 needed to be kept up and I also was part of the 00:21:23.710 --> 00:21:28.569 social media team keeping things going with social 00:21:28.569 --> 00:21:31.690 media and keeping cord in touch with the mission 00:21:31.690 --> 00:21:35.880 control team back in the Bay Area. We had, as 00:21:35.880 --> 00:21:39.039 part of the permitting process, we had to provide 00:21:39.039 --> 00:21:42.180 daily reports to the Australian Antarctic Division, 00:21:42.740 --> 00:21:46.799 who is the permitting authority, to let them 00:21:46.799 --> 00:21:49.319 know how we were doing and what we were up to. 00:21:49.940 --> 00:21:54.119 And so all of those things took time. But when 00:21:54.119 --> 00:21:58.940 you're out there, it's a real rush to be there. 00:21:59.539 --> 00:22:02.670 And so you want to stay awake for for a lot of 00:22:02.670 --> 00:22:05.670 it but get sleep when you need to so that you 00:22:05.670 --> 00:22:10.349 can actually function well. I'm sure that's a 00:22:10.349 --> 00:22:13.529 challenge and actually it's bringing to mind 00:22:13.529 --> 00:22:18.849 what I kind of envisioned for a lot of the outer 00:22:18.849 --> 00:22:22.230 space missions that you know everything's on 00:22:22.230 --> 00:22:26.170 a checklist and everything's you know kind of 00:22:26.170 --> 00:22:30.259 set and ready to go so that you know, you do 00:22:30.259 --> 00:22:33.019 just, you know, the minimal amount of deployment 00:22:33.019 --> 00:22:36.940 that you can do to make sure you get everything 00:22:36.940 --> 00:22:41.500 and get it safely back. Yeah, absolutely. I mean, 00:22:41.539 --> 00:22:44.640 if you've got, you typically have a lot of time 00:22:44.640 --> 00:22:48.259 before the expedition goes, and that's when you 00:22:48.259 --> 00:22:51.680 need to make sure that you have plans for how's, 00:22:52.099 --> 00:22:54.410 what are you going to do? What are you going 00:22:54.410 --> 00:22:57.190 to do when Plan A doesn't work or when something 00:22:57.190 --> 00:23:01.730 fails? Who's going to be doing what? What are 00:23:01.730 --> 00:23:03.970 the likely scenarios you're going to encounter? 00:23:04.450 --> 00:23:07.069 Everything that you can document or go through 00:23:07.069 --> 00:23:11.589 beforehand, you want to make sure is done and 00:23:11.589 --> 00:23:15.309 is dealt with. Because again, you don't want 00:23:15.309 --> 00:23:18.269 to expend any more energy on things while you're 00:23:18.269 --> 00:23:22.589 out in the field than you need to. So the more... 00:23:22.509 --> 00:23:25.069 the more you can plan ahead of time, the more 00:23:25.069 --> 00:23:29.009 that you can put the work of the expedition into 00:23:29.009 --> 00:23:33.029 the planning side rather than on island, the 00:23:33.029 --> 00:23:36.049 more time that you have to do the science and 00:23:36.049 --> 00:23:41.990 to the documentation that you want to do. All 00:23:41.990 --> 00:23:44.589 excellent and interesting stuff. And so we're 00:23:44.589 --> 00:23:48.930 going to give the listeners a chance to ask some 00:23:48.930 --> 00:23:52.700 questions here in just a little bit.

So if you have a question 00:27:01.819 --> 00:27:06.380 about any of the science or any of the The expedition 00:27:06.380 --> 00:27:09.180 stuff from her to island give us a call eight 00:27:09.180 --> 00:27:16.420 one two net ham one is the number so While we're 00:27:16.420 --> 00:27:19.599 waiting to see if we have any colors that that 00:27:19.599 --> 00:27:23.569 know that we're on a day early here Tell us a 00:27:23.569 --> 00:27:26.410 little bit about some of the environmental restrictions, 00:27:26.529 --> 00:27:30.730 some of the concerns that you had going into 00:27:30.730 --> 00:27:33.569 Heard Island that, you know, they don't want 00:27:33.569 --> 00:27:37.009 the environment disrupted any more than necessary. 00:27:37.390 --> 00:27:40.410 Tell us a little bit about the concerns and some 00:27:40.410 --> 00:27:43.589 of those restrictions for going there and living 00:27:43.589 --> 00:27:46.390 there for a couple of weeks and taking the samples. 00:27:47.829 --> 00:27:53.930 Sure. Well, Heard Island is a UNESCO World Heritage 00:27:53.930 --> 00:27:57.309 Site and is designated that way both for its 00:27:57.309 --> 00:28:03.430 unique geology being a hotspot type volcanic 00:28:03.430 --> 00:28:08.130 island at a place that may have some remnant 00:28:08.130 --> 00:28:11.769 continental crusts underneath it and also for 00:28:11.769 --> 00:28:16.130 its unique ecosystem. Heard Island, unlike all 00:28:16.130 --> 00:28:20.269 of the other sub -Antarctic islands, was never 00:28:20.460 --> 00:28:25.700 uh, infested with any sort of, uh, human -introduced 00:28:25.700 --> 00:28:29.000 species, at least not that anybody is aware of. 00:28:29.799 --> 00:28:34.279 Uh, there are some grasses that have probably 00:28:34.279 --> 00:28:37.180 been introduced from Kerguelen Island, uh, that 00:28:37.180 --> 00:28:39.440 may have been brought over by birds, so there 00:28:39.440 --> 00:28:42.640 are some potentially invasive species on island, 00:28:43.240 --> 00:28:46.700 uh, and we had to take special precaution and 00:28:46.700 --> 00:28:49.259 had special permitting requirements around that. 00:28:50.759 --> 00:28:59.119 It's also an IUCN strict nature reserve. And 00:28:59.119 --> 00:29:03.900 that means that there is a lot that's being done. 00:29:03.940 --> 00:29:08.019 There's a very detailed plan about the management 00:29:08.019 --> 00:29:12.980 of the island. And so it has this management 00:29:12.980 --> 00:29:16.710 plan. Talks about what biosecurity requirements 00:29:16.710 --> 00:29:19.970 you need to have in order to access the island 00:29:19.970 --> 00:29:24.269 so in order to get on the island you need to 00:29:24.269 --> 00:29:29.369 have a Rodent free ship and it needs to be certified 00:29:29.369 --> 00:29:33.609 rodent free you need to use Various measures 00:29:33.609 --> 00:29:36.390 to make sure that there are no rodents to be 00:29:36.390 --> 00:29:41.349 introduced You need to have traps set up both 00:29:41.349 --> 00:29:44.049 on the island and on the ship They need to be 00:29:44.049 --> 00:29:50.529 monitored. You also have to clean off your... 00:29:50.529 --> 00:29:53.289 Everything needs to be thoroughly cleaned before 00:29:53.289 --> 00:29:57.410 it goes on the island. Boots need to be cleaned. 00:29:57.569 --> 00:29:59.809 The tents had to be cleaned. All the gear had 00:29:59.809 --> 00:30:04.769 to be either new or pristine. And there were 00:30:04.769 --> 00:30:07.470 thorough inspections as we were loading the ship 00:30:07.470 --> 00:30:10.569 to make sure that everything was going to be 00:30:10.569 --> 00:30:12.869 cleaned and that the... environment would not 00:30:12.869 --> 00:30:18.569 be at risk from our expedition. Once you get 00:30:18.569 --> 00:30:25.029 there, it's a leave no trace situation. And that 00:30:25.029 --> 00:30:29.309 goes all the way to packing out solid waste. 00:30:29.849 --> 00:30:33.730 So all solid waste gets packed out. Liquid waste 00:30:33.730 --> 00:30:38.650 of certain types can be disposed of below the 00:30:38.650 --> 00:30:44.579 high tide line. but generally everything got 00:30:44.579 --> 00:30:48.980 put back into containers and brought back to 00:30:48.980 --> 00:30:54.480 the ship for transport on to Australia. So it 00:30:54.480 --> 00:30:57.819 was challenging to meet those protections, but 00:30:57.819 --> 00:31:02.160 when you think about how important scientifically 00:31:02.160 --> 00:31:06.960 that ecosystem is, all of those protections are 00:31:06.960 --> 00:31:09.420 quite reasonable and it's in line with the sort 00:31:09.420 --> 00:31:13.680 of protections that are in place in Antarctica 00:31:13.680 --> 00:31:19.980 and other high -value ecosystems. Very good. 00:31:20.000 --> 00:31:25.299 812 Net Ham 1 is phone number 812 -638 -4261. 00:31:25.339 --> 00:31:28.799 If you have a question, give us a call or give 00:31:28.799 --> 00:31:32.420 us a Skype call or a tweet. Just look for HamTalk 00:31:32.420 --> 00:31:36.319 Live. What was your favorite part of the trip? 00:31:38.359 --> 00:31:42.779 Well, there There were a lot of favorite parts 00:31:42.779 --> 00:31:49.480 of the trip. One of the favorite radio moments 00:31:49.480 --> 00:31:55.039 came in the first couple days. The first day 00:31:55.039 --> 00:31:58.440 that we were on the island, we set up the tents, 00:31:58.619 --> 00:32:02.880 we set up a few of the antennas, we put the camp 00:32:02.880 --> 00:32:08.259 together, and then went to bed exhausted. Although, 00:32:08.299 --> 00:32:12.000 even though we were exhausted, each of us had 00:32:12.000 --> 00:32:14.440 a one hour radio shift through the night. So 00:32:14.440 --> 00:32:20.660 we were on the radio all hours through that first 00:32:20.660 --> 00:32:26.480 night. The next day, we were working on putting 00:32:26.480 --> 00:32:29.440 up more antennas, since all of our antennas were 00:32:29.440 --> 00:32:33.579 good only at night. So we put up more antennas. 00:32:33.900 --> 00:32:38.210 And late in the afternoon, it was time to get 00:32:38.210 --> 00:32:41.569 back on the air on the lower bands again and 00:32:41.569 --> 00:32:46.109 so I Managed to be the person to get get on the 00:32:46.109 --> 00:32:48.349 air and I was a little bit daunted by that as 00:32:48.349 --> 00:32:51.329 one of the the less experienced amateur radio 00:32:51.329 --> 00:32:53.809 operators knowing that I would be coming up against 00:32:53.809 --> 00:33:01.490 a very very busy time so I Sat down in the chair 00:33:01.490 --> 00:33:07.099 got all set up Called who you know who wants 00:33:07.099 --> 00:33:10.720 to come come talk to heard island and on the 00:33:10.720 --> 00:33:16.019 very first call I get get a response from kilo 00:33:16.019 --> 00:33:22.000 6 Sierra Romeo Zulu and Get get him in the log 00:33:22.000 --> 00:33:27.319 right away and It was kind of funny because not 00:33:27.319 --> 00:33:30.200 only did I get a response on the very first call 00:33:30.200 --> 00:33:35.230 from a nice loud station, but I actually know 00:33:35.230 --> 00:33:39.789 Dr. Eshelman from my time in Berkeley. And I 00:33:39.789 --> 00:33:42.549 found out later that evening after my shift was 00:33:42.549 --> 00:33:45.849 over that it turned out that that was the last 00:33:45.849 --> 00:33:50.369 of the 340 countries and territories around the 00:33:50.369 --> 00:33:53.210 world that he was looking for to get the complete 00:33:53.210 --> 00:33:58.289 set. So it was fun that my first contact of the 00:33:58.289 --> 00:34:03.980 day was then on the first call. was someone that 00:34:03.980 --> 00:34:09.159 I knew and for his uh for his last of the 340 00:34:09.159 --> 00:34:14.900 territories very nice very nice what are some 00:34:14.900 --> 00:34:18.380 other uh some of the other favorite moments there 00:34:18.380 --> 00:34:22.420 well it was also kind of fun uh while we were 00:34:22.420 --> 00:34:26.639 on the ship um we had quite a bit of time to 00:34:26.639 --> 00:34:31.019 uh sit and watch the scenery uh and one morning 00:34:31.019 --> 00:34:37.320 I Got up and we were we were welcome to go on 00:34:37.320 --> 00:34:41.119 to the bridge to see what was going on and spend 00:34:41.119 --> 00:34:45.559 time with the officer of the watch up there and 00:34:45.559 --> 00:34:48.539 so I went up and One morning just to see what 00:34:48.539 --> 00:34:51.039 was going on and was told. Oh, we've got some 00:34:51.039 --> 00:34:54.639 dolphins off of our bow. So I got to go out Go 00:34:54.639 --> 00:34:57.920 out on deck and take a look as these dolphins 00:34:57.920 --> 00:35:01.980 were Just playing around right in our bow wave 00:35:01.980 --> 00:35:06.820 just inches from the ship. So it was fun to see 00:35:06.820 --> 00:35:11.719 those. It was also a lot of fun to see these 00:35:11.719 --> 00:35:19.239 new to me sea birds. And it made me feel... It 00:35:19.239 --> 00:35:24.920 was a very tough time identifying the birds because 00:35:24.920 --> 00:35:28.679 as a Minnesota and California resident, I had... 00:35:28.750 --> 00:35:32.829 was not familiar with my southern ocean seabirds. 00:35:32.989 --> 00:35:36.590 Albatrosses were completely new to me. And so 00:35:36.590 --> 00:35:40.510 it was a challenge looking at the birds and trying 00:35:40.510 --> 00:35:43.949 to pick out the distinguishing marks, particularly 00:35:43.949 --> 00:35:46.730 given that some of the southern ocean seabirds 00:35:46.730 --> 00:35:49.670 are known for being very difficult to distinguish, 00:35:50.409 --> 00:35:52.809 sometimes even difficult to distinguish if you 00:35:52.809 --> 00:35:56.349 have them right there in your hand, which I didn't. 00:35:56.619 --> 00:36:00.360 They like to move quickly and stay just far enough 00:36:00.360 --> 00:36:03.840 away from the camera to make it hard to get pictures 00:36:03.840 --> 00:36:10.380 of them. 812 Net Ham 1 is the phone number 812 00:36:10.380 --> 00:36:16.820 -638 -4261 and we'll keep on talking here while 00:36:16.820 --> 00:36:21.199 we're waiting for your calls. So go ahead and 00:36:21.199 --> 00:36:24.119 give us a call whenever you want and we'll get 00:36:24.119 --> 00:36:27.769 you in here. Now tell us a little bit about your 00:36:27.769 --> 00:36:32.070 blog and some of the data. We've mentioned a 00:36:32.070 --> 00:36:35.030 little bit of some of the things that are available 00:36:35.030 --> 00:36:39.630 there on your blog. So talk a little bit about 00:36:39.630 --> 00:36:42.949 some of this data that's openly available for 00:36:42.949 --> 00:36:49.010 people to see on there. Sure. So one of the purposes 00:36:49.010 --> 00:36:52.829 of the blog that I have, and that's Inquisitive 00:36:52.829 --> 00:37:01.900 Rockhopper, One of the purposes is to help me 00:37:01.900 --> 00:37:05.960 make sure that I do do the reading to know what's 00:37:05.960 --> 00:37:08.559 going on on Heard Island, but then I try and 00:37:08.559 --> 00:37:12.679 share that with my readers as well as looking 00:37:12.679 --> 00:37:16.059 at some of the current events that are visible 00:37:16.059 --> 00:37:20.039 by satellite on Heard Island. So earlier this 00:37:20.039 --> 00:37:25.449 month on February 4th Landsat 8, which is one 00:37:25.449 --> 00:37:30.130 of the U .S. Earth observing satellites, flew 00:37:30.130 --> 00:37:34.829 over Heard Island and was taking images in a 00:37:34.829 --> 00:37:40.090 number of different wavelengths or colors. And 00:37:40.090 --> 00:37:43.110 I've been watching these images for quite a while. 00:37:43.530 --> 00:37:48.829 I took a look at this one and it was really incredible 00:37:48.829 --> 00:37:54.679 because we had in the image some visible lava 00:37:54.679 --> 00:37:59.760 or debris flows at the summit of the volcano 00:37:59.760 --> 00:38:05.900 and when I looked at the infrared bands it was 00:38:05.900 --> 00:38:09.800 clear that there was at least an active eruption 00:38:09.800 --> 00:38:14.039 or there was at least hot material at the surface 00:38:14.039 --> 00:38:17.480 near the summit and also what I interpret as 00:38:17.480 --> 00:38:22.849 a active lava flow. at the time as this satellite 00:38:22.849 --> 00:38:26.449 flew over. So that was a really interesting thing 00:38:26.449 --> 00:38:29.230 to see. And I've been looking at some of that 00:38:29.230 --> 00:38:33.869 as well as sharing a little bit about how to 00:38:33.869 --> 00:38:38.289 find the images and how to process the images 00:38:38.289 --> 00:38:43.590 using some software called QGIS, which is pretty 00:38:43.590 --> 00:38:49.340 neat. I also did a little bit of modeling. of 00:38:49.340 --> 00:38:52.320 an interesting problem with some of the seabirds. 00:38:54.719 --> 00:38:59.539 I had four or five pictures of birds that I'd 00:38:59.539 --> 00:39:04.739 taken from a flock of about 40. And it was expected 00:39:04.739 --> 00:39:08.980 to be a mixed species flock, and all four of 00:39:08.980 --> 00:39:12.699 the photos were of one species, which was expected 00:39:12.699 --> 00:39:18.099 to be the less frequent species. So I wanted 00:39:18.099 --> 00:39:22.260 to know how many of those were, could I statistically 00:39:22.260 --> 00:39:28.699 say, were in that flock, and ended up doing some 00:39:28.699 --> 00:39:33.800 computer modeling to figure out how many I could 00:39:33.800 --> 00:39:37.059 definitively say, or at least justifiably say 00:39:37.059 --> 00:39:40.599 were in that. And it was about half of them. 00:39:45.130 --> 00:39:50.190 I guess I would also be remiss to point out that 00:39:50.190 --> 00:39:53.210 some of what I've talked about on the blog and 00:39:53.210 --> 00:39:56.289 I talk about on Twitter is, of course, the gratuitous 00:39:56.289 --> 00:39:59.690 penguin pictures. There are four different species 00:39:59.690 --> 00:40:03.329 of penguins that breed on Heard Island, king 00:40:03.329 --> 00:40:07.510 penguins, gentoo penguins, macaroni penguins, 00:40:07.769 --> 00:40:11.909 though I feel like if they had a radio microphone 00:40:11.909 --> 00:40:14.280 or a Morse code key in their hand. They might 00:40:14.280 --> 00:40:20.880 be a Marconi penguin. There we go. And my personal 00:40:20.880 --> 00:40:26.719 favorite, the southern rockhopper penguin. So 00:40:26.719 --> 00:40:29.340 all four of those breed on the island and we 00:40:29.340 --> 00:40:33.639 were able to find penguins of each of those species. 00:40:34.460 --> 00:40:37.639 The rockhoppers were a little bit tricky to find 00:40:37.639 --> 00:40:42.670 because they they like to stay on Well pretty 00:40:42.670 --> 00:40:45.869 rocky places and in lava tubes and in places 00:40:45.869 --> 00:40:48.789 that humans have trouble getting to either because 00:40:48.789 --> 00:40:52.610 it's just physically difficult to access or because 00:40:52.610 --> 00:40:58.349 much of the island has significant protections 00:40:58.349 --> 00:41:01.170 so even though we were a scientific expedition 00:41:01.170 --> 00:41:04.289 There were a number of places that the permit 00:41:04.289 --> 00:41:08.949 said You are not to go here because there are 00:41:08.949 --> 00:41:11.800 lava tubes that might be under foot that could 00:41:11.800 --> 00:41:16.579 collapse or there are sensitive bird areas and 00:41:16.579 --> 00:41:19.320 the scientific activities that you've proposed 00:41:19.320 --> 00:41:23.860 don't require you to be there so don't go there. 00:41:25.099 --> 00:41:29.059 Yeah, very good and we just tweeted out the link 00:41:29.059 --> 00:41:33.420 to the to the blog that you're mentioning the 00:41:33.420 --> 00:41:36.699 inquisitiverockhopper .wordpress .com and I'll 00:41:36.699 --> 00:41:39.380 get that out on Facebook here right after the 00:41:39.380 --> 00:41:43.219 show. but that's on Twitter right now so you 00:41:43.219 --> 00:41:48.280 can go take a look at that at your leisure and 00:41:48.280 --> 00:41:53.480 we're just about out of time here so any closing 00:41:53.480 --> 00:41:56.079 thoughts you want to get in we've got about a 00:41:56.079 --> 00:42:00.199 minute left. All right yeah well this this was 00:42:00.199 --> 00:42:04.030 really a wonderful Expedition to be part of it 00:42:04.030 --> 00:42:07.590 was great to have so much support from the community 00:42:07.590 --> 00:42:11.110 Throughout the process both at the front end 00:42:11.110 --> 00:42:14.949 and then while we were on island And then it 00:42:14.949 --> 00:42:18.210 was fun hearing from Folks even on the radio 00:42:18.210 --> 00:42:20.949 as we were on the ship on the way home made a 00:42:20.949 --> 00:42:24.230 few contacts there and had a lot of people Who 00:42:24.230 --> 00:42:27.690 were clearly looking looking out for us? So it 00:42:27.690 --> 00:42:30.090 was really wonderful to be part of the expedition 00:42:30.090 --> 00:42:33.750 and it's been a a great time learning about the 00:42:33.750 --> 00:42:37.230 science and history of Heard Island.
