July 17 3:30 am (Central time) Winnipeg: Under starry sky, four very sleepy scientists were waiting for the arrival of the charter flight carrying about 60 Coastguard crew and scientists from Quebec. Amundsen Chief Scientist for leg 10a, Gary Stern; graduate students, Lauren Candlish and Amanda Chaulk; and I (Research Scientist of Environment Canada, Hayley Hung) were half-asleep when we boarded the plane at around 5:30. We were making our way to Yellowknife where we would split into 2 Convair flights to Kugluktuk. It was a very long journey even if the charter planes did not stall twice and delay for 5 hours in total. At Kugluktuk, we were transported to the ship on a helicopter. To move 60+ people onto and off the ship in a helicopter was a very slow process. We finally all made it...

In a period of 48 hours, our weather has changed three times, from (almost) Miami Beach-type temperatures, to driving snow, and back to sun late this afternoon. Lingering morning snow prevented a survey of the region by helicopter. Instead, time on the ground gave the scientists an opportunity to finish building their instrument towers. We also have started to pack camp, stacking trash bags and tools about 200 feet from our tent in preparation for our scheduled helicopter ride off the ice tomorrow morning. There is still no word about Sarah Das’s dye, which she poured in a moulin several days ago to track drained lake water flowing from the base of the ice sheet to the coast. Our source on the coast south of Ilulissat (Sarah’s graduate student, Maya Bhatia) said recent s...

A 150-meter ice core pulled from the McCall Glacier in the Arctic National Wildlife Refuge this summer may offer researchers their first quantitative look at up to two centuries of climate change in the region. The core, which is longer than 1 1/2 football fields, is the longest extracted from an arctic glacier in the United States, according to Matt Nolan, an associate professor at the University of Alaska Fairbanks Institute of Northern Engineering who has led research at McCall Glacier for the past six years. The sample spans the entire depth of the glacier and may cover 200 years of history, he said. “What we hope is that the climate record will extend back into the Little Ice Age,” said Nolan. “Up until the late 1800s these glaciers were actually gr...

Packing seems to have become a major component of our lifestyle. Our house is mostly one big room which seems to spend most of its time full with piles of gear in some stage of being packed or unpacked. Right now we’re packing for three trips – we leave for Colorado tonight for a week, we leave for a backpacking trip into the glacier a few days after we return, and we have 5 weeks on the glacier after that. The glacier portion is the most work to prepare for, as we’re packing this with the plan of dropping it down to the glacier from the plane, in case the plane is unable to land on the ice. So everything has to be packaged to survive a drop of 100 feet and a crash landing at 50 mph. I have no prior experience at air drops, so this is sure to be a learning experience. Fortunately its...

The past few days for me have been consumed by a press release that UAF sent out describing our ice coring success. I had written a draft of the release several weeks earlier and sent it out to our UAF public information office on our arrival in Kaktovik, but it took some time to work through the system and go through a few iterations. Here is a link to the initial release. Much of the time related to this got soaked up getting photos ready. I had prepared a bunch the week before, but then I was told we needed model release forms from everyone in the photos. Of course nearly all my photos have people in them, and most of these people are hard to get hold off in summer. So then I had to sort through to find...

With Benny gone and our next departure still a week away, we had a brief lull to remember what summer in Fairbanks is like. We also caught up a bit with a few old friends and Turner had the chance to visit with his friends too. In between we shopped for food for the next phase of the trip (about 160 man-days worth) and began considering how to package this for air-drops. I stitched a few of my high resolution panoramas – composed of 300 to 500 shots each – and was relieved to learn that they stitched beautifully for the most part. I’ll try to upload them in the next week, but they are multi-gigabyte files and I may not have the chance. ...

Given that the weather was not improving and that Nick and Jessica had the Kaktovik scene figured out, we decided to head back to civilization a bit earlier. We had begun settling into Kaktovik life pretty well and enjoyed our visits with the neighbors and the chaos of Waldos, but the list of things to do to prepare for the next phase of the trip began growing longer and longer the more we thought about it, and the list of productive things to do in Kaktovik was getting pretty short. So once Turner got his stitches out, we switched our reservations and headed back to town. Huge snowfences surround the infrastructure of Kaktovi...

Benny arrived from LA a few days ago and today we went on our first photo flight. Benny is a professional photographer and specializes in aerial photography. He brought with him several high-powered cameras and helped me figure out how to use the one I bought from him on ebay. My camera uses 5 inch wide negative film to take 4”x5” photos, compared to 35mm film which is less than 1” squared. One of Benny’s cameras takes 8”x10” photos. He built this camera himself, machining it out of a solid block of aluminum to be lightweight and aerodynamic. Another camera has 39 megapixel resolution, compared to my high-end Nikon which has only 12 megapixels, and it also has 12 stop dynamic range, which greatly exceeds a digital Nikon at about 6 and even black and white film at 10. So we look...

After 50 years of attempts, a high resolution map of McCall Glacier may have just been acquired. During the International Geophysical Year 1957-58, eight glaciers in Alaska were selected for long-term research. A primary component of this research was the use of topographic maps – by making such maps periodically, the evolution of the shape of the glacier could be tracked and its dynamics better understood. McCall Glacier was the centerpiece of this research and the only glacier of the eight where a major field program was established. As such, the first tests in making topographic maps were done there as that is where it would be most useful to the field team. Unfortunately, circumstances prevented the mapping team’s return to McCall Glacier, and all that we were left with is a map ma...

I was up at 4:30AM to check weather, which was nearly perfect, and I checked in with Jessica and Nick to let them know that today could be our day. We only need about 3 days of this weather to complete the project, and in one day we could gather our most essential data. They arrived from Deadhorse about 7AM and we quickly redeployed the ground-based GPS. I sat in the truck as they taxied off, waiting around to get a picture of them taking off with the background of mountains. But they never took off. I called them on the radio and they said they were having issues with the lidar. So they came back to the ramp and we fooled around with things a bit more. I unplugged their antenna going to the top of the plane and plugged it back in, and about this time the unit came alive again. So they tax...
