What is productivity?

This past field season was a struggle and so it was quite a humbling experience. Last year everything went really well, so I kind of expected more of the same... The instruments that we left running over winter failed, and nearly every instrument that we brought with didn’t work as it was supposed to — at least not at first. This included a wind gauge, a precipitation gauge, a marine radar (for tracking iceberg motion), an automatic theodolite (for optical surveying), several GPS, and an ablation meter (measures ice melt rates). On top of that we had some pretty bad luck with weather during the first two weeks at our camp. The first night that we were there we had 60+ knot winds. Martin lost his tent in the wind and broke his glasses when they were blown off his face. All of the tents suffered some damage. A week later we got hit by another storm. You could hardly stand up outside, let alone try to do something productive. This was also probably the first time that I’ve ever slept with ear plugs. It was really something. I’m sure I’ll remember it fondly some day. Check out this poor tent:

In the end we managed to accomplish most of what we had set out to do. At any rate, it gave me a new perspective on how difficult field work can actually be. I was certainly feeling pessimistic about our work for a couple of weeks.

During the last two weeks — we were out for a month — the weather cleared up. Actually, it was amazingly beautiful weather. It was actually hot, and there was very little wind. That’s quite unusual, because large glaciers often have strong winds blowing down-glacier. We had a lot of time to relax during those two weeks. I passed my time by reading Finnish children’s stories and cleaning up all the dirt. Its really a dirty place.

We also played network video games (not really),

ate narwhal,

and formed a band (photo for the c.d. cover).

Return to summer

I sometimes think that glaciologists - especially those who chose to live in Fairbanks - must be really stupid people. I spend my winter in the dark and cold, and once spring arrives I travel to Greenland so that I can sit next to a giant ice cube all summer... Well, that's not to say that I didn't enjoy being in Greenland, because I did. But its also really nice to be back in Fairbanks. Everything seems so green, and its warm and the flowers are blooming and the birds are chirping.

I've started keeping a journal while doing field work because after a while the days blur together. I'll try to type up some of my entries and post them here. Maybe they're interesting?

For now, I'll leave you with a link to a video that I put together. About once a week we witnessed a BACE (bad ass calving event), during which a large part of the glacier tongue would break off and roll around in the fjord, making a lot of noise in the process. The icebergs are huge- the ice cliff that you'll see in the video is 80-100 m high, meaning that the ice is on the order of 800 m thick. Try picturing that rolling around in your neighborhood! This particular calving events lasted for about 20 minutes; I took one frame every 10 seconds and compressed the whole sequence into about 20 seconds.
