Day 82-83: Settling into civilization
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.

Day 79-81: Return to civilization
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...

Day 78: High-resolution aerial photography
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...

Day 75-77: Lidar success!
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...

Day 74: Celebrating Independence Day and a bit of lidar success
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...

Day 73: Our first injury of the trip
Our first serious injury of the trip occurred today. People often ask me about the risks associated with working in the remote field, and my contention has always been that it is safer there than in civilization. In the field, the situation is simple – we need to be concerned about weather, animals and glacier travel, plus a few things associated with camp life like tent stability and stove safety. But in civilization, there are countless potential risks – things associated with vehicles, buildings, fuels, people, etc etc. In this case, we spent the late afternoon helping Walt shuttle passengers to the airport. The weather was marginal and not good enough to land, so we stayed down at the strip encouraging the Frontier pilot circling overhead to hang out to the last possible minute as ...

Day 71-72: The chaos begins
After our first night’s sleep in a bed, the anticipated chaos associated with our major lidar campaign began. Nick and Jessica from Aerometric showed up in the morning in their Piper Navajo equipped with their lidar unit. The lidar is essentially a laser beam that sweeps left to right as they fly forward, measuring the distance to the ground along a swath determined by the sweep angle of the lidar. In our case, this swath is a few kilometers wide by the time it reaches the ground from 12,000 feet. As they fly, a GPS unit in the plane is used to determine their position, corrected by the ground-based GPS we deployed in the field the day before. We also deployed a few more GPS here in Kaktovik to improve these corrections and give them some preliminary data to use to ensure the day’s acq...

Mother fox
Predators do shape the arctic fauna. This year, the den next door is the only den with young. We have counted 8 puppies but saw the smallest one dead within a few days.
Two wildlife photographers have been visiting us and taken pictures like these. More about the marking of the puppies on www.arcticstation.nl.

Environment Canada launches IPY web site
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...

Nolan on McCall Glacier: Hard science, caribou stampedes and mosquito squadrons
University of Alaska Fairbanks glaciologist Matt Nolan has just completed the second phase of an extensive study of McCall Glacier in northern Alaska, briefly returning to civilization after over two months on the glacier with heaps of ice cores and measurements of glacier dynamics, but also with some great panoramic photos, timelapse photography, and videos of his young son Turner skiing for the first time.
Matt’s daily documenting of what scientists (and his family) get up to on an glacier expedition has now been posted to IPY.org, with many new panoramas and video. You can read all of Matt’s entries, in reverse chronological order, but below are just some of the highlights:
