No flights for seven days

November 14, 2012

A panorama from the Rothera hangar to South Cove. On the right is a Basler aircraft called Polar 6 that has stopped in Rothera en route to Neumayer Station and operated by the Alfred Wegner Institute. All other aircraft on station are hunkered down in the hangar today awaiting a break in the weather.

Haven’t flown since November 7. I have been doing eight-lap runs around the runway in between testing our instruments. Each lap is a little more than a mile. When its too snowy and blowy, I run on the treadmill.

On November 9, the Lake Ellsworth drilling team arrived via Dash-7, and about two hours later we had our first fire drill while I was doing stretches in my room. With the fire alarm blasting, I hurried into my boots and jacket. I hustled down to New Bransfield house, the primary emergency muster point, where each on-site person needed to check in. After a couple of minutes, the alarms ceased, and everyone went back to what they had been doing.

I decided to replace the ten-image 2001 UTC acquisition at Flask AMIGOS-3 with a 0901 UTC acquisition so that Steve Crampton, Rothera’s weather forecaster, could have it available when preparing his 0745 Rothera Time (i.e. 1045 UTC) daily weather briefing for the pilots and field teams. I first uploaded the changes to AMIGOS-2 in Boulder, then AMIGOS-3 on Flask.

On November 11, I worked as a “gash” all day, mostly cleaning the bar after the usual Saturday night revelry, cleaning the upstairs washrooms in New Bransfield, and washing pots in the kitchen. After that, I played guitar after dinner with three other guys in the music room in Old Bransfield.

The weather has been bad the last three days. It had been snowing and blowing in Rothera, and presumably in the Larsen B region. Still not getting the 0901 image on AMIGOS-3. Investigation showed that the updated schedule checker script did not finish loading, so I reloaded a copy this time to a temporary file, verified that the copy loaded ok, then renamed it.

I started getting Roger Stilwell up to speed on the AMIGOS and cGPS instrument upgrade and repairs, as it appears Roger will be replacing Malcolm Airey who will start working with another field group.

Looks like I’ll be flying tomorrow to Scar Inlet with Roger, Daniel, Daniel’s field assistant Ash Fusiarski, and a pilot to service the Scar Inlet AMIGOS-4 and Daniel’s Scar Inlet GPS, and whatever else we might have time for.


Election news and preparations for flight number two

I was happy to see this morning that my candidate had won. No flying or even a weather briefing, so I spent the entire day writing and dealing with yesterday’s photos. Noticed that the Scar Inlet slot nearest AMIGOS-4 seemed wider than I remembered seeing in previous photos that Ted had taken. Was informed that afternoon that we are scheduled to fly again tomorrow. Our equipment is still in the hangar, and I’ll try to make any lunch preparations tonight, so hopefully I won’t be the one to hold things up this time around. Oh and I’ll try to remember the Canon this time.


Rothera to Flask Glacier

November 6, 2012

The weather brief at 0745 indicated good conditions over Larsen B sites, but deteriorating conditions at Rothera. We were assigned helper John Eager and chief pilot Alan Meredith. Alan said we needed to return by 1700. Did rush job to get dressed, load all equipment (so we could work at any of the five sites) and make three lunches for Malcy, John, and me. In my haste, I left the Canon camera in the Old Bransfield dressing room.

While I was making sandwiches in the kitchen at 0855, a PA announcement asked if anyone had seen Terry. I called Ops and said I was almost done. I rushed outside just as Clem pulled up on a Gator to drive me to the Twin Otter. The wind was already rising and the clouds were moving in. I hopped into the plane, with Malcy in the co-pilot’s seat, John behind him, and me behind John. Malcy told me we were going just to Flask not Scar Inlet nor anywhere else. We took off at 0910.

After 20 minutes, we had clearing to the west and clouds to the east. Another 20 minutes and it was all clouds. Then over the divide east of Larsen C, we had clouds to the west and clear skies to east all the way to Upper Leppard Glacier and Flask Glacier, whose fjord we entered at the AMIGOS-3 location, which I spotted out the window.

I undid my seat belt, stuck my head in the cockpit, and told Alan we were at AMIGOS-3 not cGPS FLSK. Apparently Andy had given him the wrong coordinates. I told him (which of course involves yelling to be heard above the roar of the engines) that we needed to go farther upstream which we did.

After a few minutes we spotted a solar panel installation, made a touch and go pass, and then landed. I remarked that the bottom of the panel was well above the snow, so it didn’t need to be raised. We unloaded all our equipment, I took some photos, and we started digging and immediately encountered an ice layer. We managed to get through the ice and exposed the top of a metal box.

It didn’t look like the top of the gray Hardig enclosure I was expecting. Malcy asked what was in the box, and I joked that maybe it contained whiskey. Then I noticed that the weather sensor was missing and must have blown off, and then that the antenna was mounted with the solar panel instead of separately, and then that the panel was too small, and then I said, “This is the wrong GPS system.”

I’m not sure it was the most embarrassing moment in my life, but it ranks right up there with pooping in my pants during class in the second grade. My coworkers were a bit peeved to have spent half an hour vandalizing someone else’s GPS, but they seemed to have taken it in stride. God (or maybe just Google) only knows what they said behind my back. So we piled ourselves and our equipment back into the plane and I provided Alan with the correct coordinates. He said it was another 2.9 miles up the fjord so off we went.

A few minutes later we located the correct site, made another touch and go pass, and landed at about 1115 Rothera Time (RT), about one hour after our first landing. Again we unloaded everything and I took some pictures. The bottom of the solar panel was 50 centimeters above the snow surface, which, if we’d had more time, would have indicated that we needed to raise the panel.

Alan had told us we needed to leave in three hours, and since I knew I had to replace the electronics at this site, I decided we would not raise the panel. We started digging, and again struck some ice, enough that Malcy need an ice axe to get through it, particularly a layer directly under the panel. We quickly reached the top of the enclosure less than a meter below the snow surface. After another 20 minutes, we had cleared a shovel width around the enclosure down to a depth about two inches below the bottom of the lid.

I took photos, and we undid the latches and raised the lid at 1217 RT. I took photos of the electronics inside. I could see the leftmost two LEDs were off, the next two were flashing, and the rightmost two were lit steady which I believe indicated that the system was still recording data, but just not able to send it back to Boulder. Continuing the detailed instructions I’d received from Seth White of UNAVCO, I powered down the receiver, and then turned off the three power circuit breakers. I asked the other three team members to swap out the WXT520 weather station while I swapped out the Iridium modem and the Trimble GPS receiver.

Correct cGPS FLSK unit that we repaired and upgraded.

Once we had completed all the equipment swaps, I took more photos, powered up the circuit breakers, and then made the first call to Seth at 1345 RT. He told me to latch up the box, he would run some tests, and to call him back in 10 minutes. When I called him back, he said that FLSK had answered the phone, but he couldn’t connect, so he had me unlatch and reopen the box, and start inspecting the wiring. I also told him I could only see one green LED lit. After a minute or two talking to him, I noticed that I hadn’t reconnected pin 2 on the timer circuit after disconnecting it in order to reroute the pin 1 and pin 3 connections. I reconnected pin 2, and Seth was then able to disconnect. I told him I could still only see one green LED, which puzzled him until I realized I was still wearing my sunglasses. I took them off, and then saw the same pattern I saw when I first opened the box. He said everything now looked good to him, so we closed up the box again and loaded up the plane.

I asked Alan if we’d have time to fly over Scar Inlet to see inspect the crevasse situation, and he said we did. I asked Malcy if I could sit in the co-pilots seat this trip, and we took off at 1430 RT. We again made a pass over AMIGOS-3 and I took some photos, one of which actually came out (barely). We flew over the heavily crevassed region of Flask Glacier downstream of AMIGOS-3, and found AMIGOS-4 on Scar Inlet about five minutes later at about 1445 RT. We made a pass around the station and this time I got better photos. Alan said that the crevasses around the station precluded landing nearby, but he didn’t see any problems landing off a kilometer or so to the east as Steve King had done last year with Ted Scambos.

I then gave Alan the cGPS LPRD coordinates (easier to do with the headset on). I didn’t get any photos but I could easily see that the snow level is up to the bottom of the solar panels, so we’ll need to raise them, probably by just extending the existing splints. And we should have time to do this since I don’t have to swap out any electronics, just upgrade the firmware and the configuration. We then left at about 1500 Rothera time or so.

Weather in Rothera was considerably worse than we had left. We landed at 1620 Rothera time under a 500-1000 foot ceiling into a northerly 25-30 knot wind and moderate snow. Andy B acknowledged a minor share of culpability for the cGPS error, and said that he had since rechecked all of our other four locations that he had given the pilots and they all looked good. Took lots of appropriate but gentle ribbing at dinner about my error earlier in the day. Turns out that the mistaken GPS was one of the units that Daniel needs to visit to collect data, so the fact that we uncovered it was not a wasted effort.

Was too nervous about the presidential elections to head to the bar and spent the evening downloading exit poll results. Most of the polls were still open when I went to bed around 2200 RT and there weren’t many real results available yet. Note that with the end of daylight savings in the states, MST is now four hours behind Rothera time, which in turn is three hours behind Coordinated Universal Time (UTC).


Flight preparations

Mike’s Ablation Valley group left after lunch, the first Rothera-based field deployment of the season. I was informed by field operations manager (FOM) Andy Barker that we are scheduled to fly tomorrow morning to attempt Scar Inlet, Flask Glacier, and maybe Leppard Glacier. I continued charging batteries and repacking equipment. Set up Iridium dial-out setup on Old Bransfield porch. I dialed in and connected to the cGPS unit on Leppard Glacier. I also called the cGPS on Flask, which answered the call but did not connect. I will need to swap out the electronics at Flask.

After discussions with Tamsin and Malcy, I decided against bringing solar panel leg extensions to Flask, and just raise entire station if necessary.


Battery news

November 4, 2012

Terry writes:

Unpacked equipment in my office. Moved batteries from charging shed to my office. Started minor remaining charging. Tested AMIGOS-1. Noticed some resetting that occurred a few times when first powering up, but then went away, similar to what I had seen in Boulder. Got an e-mail from Chris Hill that the batteries I gave him tested good, but that he would be unable to use them since they are gel-acid and his charger only works with wet-acid batteries. So I told him to just leave them in the AGUNSA warehouse and I would deal with them after I get back to Punta Arenas.


A belated Halloween party

November 3, 2012

Field assistant Dave Routeldge and Terry (right) at the Rothera Research Station Halloween party.

Terry writes:

After breakfast in the tent, we broke camp, and then piled into the tractor with another group of campers, leaving Ian, Mike, and Mike’s Aberystwyth University post-doc Bethan to do a full day of Mountaineering Training. The three of them will be spending the rest of November and most of December doing fieldwork reconstructing the glaciological history of Ablation Valley on the East coast of Alexander Island on George VI Sound.

After getting back to the station, I did laundry, called Sue and her dad Red at his 90th birthday in Arkansas, retrieved my computer and electrical equipment, downloaded pictures from my cameras, and, most importantly, assembled my costume for the Halloween party that evening. The “fancy dress” room upstairs in Old Bransfield had just what I was looking for: black, elegant, glittery but still understated, except possibly for the shiny cowboy boots. My only slight disappointment was that I had to settle for a cotton rather than a leather skirt.


Pitching pyramid tents

Terry attends camping training in near Rothera Station. Although researchers like Terry have camped on Antarctic ice many times, they have to attend this training to refresh their skills.

Terry Haran participates in camping training in near Rothera Station. Although researchers like Terry have camped on Antarctic ice many times, they have to refresh their skills before each expedition.

Terry writes:

Spent the morning on field training with field assistant Ian Hey, learning about British Antarctic Survey camping procedures and equipment. Then in the afternoon Ian and the other students in my group, including Mike Hambrey, Bethan Davies, and Alex Brisbourne, traveled by snow tractor about six kilometers up “The Ramp” to the field training area next to “The Kaboose.”

We pitched two “pyramid tents” (called “Scott tents” in the US program), wherein my tent mate Alex and I cooked dinner, talked about 60s rock groups (of which he was surprisingly knowledgeable despite being only 39 years old), and went to sleep.


Training days

I spent all day at training sessions, including Aircraft Familiarization, Station Communications, Environmental & Medical, Vehicle Familiarization (where we got to drive Gators and snowmobiles), and Field Medical Box (where we each got to give a dummy an injection of real but expired adrenaline).


Punta Arenas to Rothera Research Station

October 31, 2012

Looking out to the west on the Dash-7 about 20 minutes before landing in Rothera Research Station.

Terry writes:

I attended a short Dash-7 flight briefing at the Almagro with my twelve fellow passengers. Then they all piled into two vans, while I got VIP treatment again as the sole US Antarctic Program/DAMCO passenger to the Punta Arenas airport, this time with Octavio and a driver. The four-hour flight to Rothera was uneventful until the final half hour or so when the Antarctic Peninsula and Adelaide Island sea ice, glaciers, and mountains came into view and people crowded around windows to take photos.

Got off the plane. Shook hands with Clem Collins, the aircraft operations chief who I had met during my previous visit to Rothera in January and February 2010. Following a brief orientation meeting, I touched base with science liaison Tamsin Gray, met my designated field assistant Malcolm Airey, and moved into my room in Giant house. My roommate is Mike Hambrey, who works with glacial geomorphologist Neil Glasser. I am to share a science office in Old Bransfield with Daniel Farinotti, who will also be doing GPS and radar work on Scar Inlet as well as on Starbuck and Flask Glaciers.

Took a short walk around the point and took a few photos. Lots of snow on the ground and lots of sunshine here. Got training all day tomorrow and part of Friday.

Much ado about batteries

October 30, 2012

A set of eight batteries left over from the 2010 Nathaniel B. Palmer LARISSA cruise that are to be sent to Rothera Research Station to replace any British Atlantic Survey batteries that I use on my current trip.

Terry writes:

Went for a bit longer run northeast of the hotel along the ocean highway. Walked over to the AGUNSA warehouse, which is next door to the DAMCO warehouse and is being used for staging the equipment for the Lake Ellsworth crew. Their leader, Chris Hill, asked if I had any extra batteries. I said I need five myself and would check back with him.

Back over at DAMCO, I met Gene Domack who had arrived on the Lawrence M. Gould (LMG) icebreaker around three in the morning. We started looking for some of Gene’s batteries that he had unloaded that morning off the LMG, but we immediately found a set of eight batteries with a C-514 TCN label assigned to Ted Scambos that were from our 2010 LARISSA Palmer cruise. I gave two to Chris Hall of the Lake Ellsworth drilling project, so when they make their big discovery of unique bugs in the lake this season, we can say, “Those guys used some of our batteries!” Chris was going to charge and test them, and let me know if they are okay. He and his crew will be stopping in Rothera next week.

Took a nostalgic tour with Chris Linden of DAMCO to the Nathaniel B. Palmer (NBP) icebreaker, which is in Punta Arenas until January. Got invited to the end of cruise dinner at Mamasita’s, drank too much wine, crawled to a couple of bars with the dwindling LMG crew, and staggered back to the hotel around 2:30 a.m.
