Flight-seeing whale-watching Barrow Style!

April 15. Up in Barrow for a week for fieldwork. This is longer than usual because we're involved in a few projects at the moment. The International Polar Year (IPY) is starting up, and our group is part of a enwly-funded project to examine the seaonal ice zone aroudn Alaska. Rather than the perenial Arctic ice pack, the seasonal ice zone refers to areas which tend to be ice covered in the fall/ winter and ice-free in the summer. This includes a lot of the coast around Alaska. As with any self-respecting contemporary science project, this one has a suitable acronym: SIZONet (Seasonal Ice Zone Observing Network).

Today, as part of this project we flew in a Bell 212 Helicopter about 50 km North of Barrow, out over the sea ice. We set down on some 3m thick multi-year ice and cored and measured depth-profiles either side of a pressure ridge that separated older multi-year ice from some of this season's first year ice. The MY ice is blue, hard and fresh, and the FY ice saline and more plastic/ softer. Just as well the drill died while coring the softer, thinner FY ice!The thickness of the ice that Oceanographer Mark Johnson is standing on is about the height of the coring barrel. We soon had power drill problems and used the manual head to turn the corer into the ice by hand. This pic shows the bottom section of the 1.25 m long FY ice core we extracted. The faint coloration at the bottom is actually algae. This thin greeny-brown layer spread over millions of square kilometers, underlies the Arctic food web. The algae get into the thin brine layers than form as the sea water freezes: the salts can't be incorporated into the H20 crystal structure of ice and end up in briney inclusions, pockets and tubes.
Here one of the pilots, Scott, is talking shotguns with me (red), Mark and the other pilot, Anders. We saw no bears or tracks, but did see a bowhead whale breaching to breathe in a lead (open water in the middle of the ice pack), which was actually pretty cool! The lower whaling crews are now cutting trails throug the ice off of Barrow so they can access their wahling camps at the edge of the large lead that runs about 10 miles offshore. This lead is close to the underwater Barrow chanel through which the bowheads migrate both in the fall and in the spring.

Spring a leak..

Spring is slowly but surely upon us. The surest sign is the dri-drip-dripping of melting snow on the roof. Most is gone too except the patch on top of the flat section above the attic window - too bad this feeds a continual dripping onto the roof right next to our pillows!

We're definitely into 'brown spring' now though, and due to the low snow year we should be through that quickly. Turns out that March was the coldest since 1959 and within a whisker of edging that for the coldest on record - which the Februay-March combo was. 111 consecutive days with daily lows below 0 F (-18 C).

Easter stunk up on us and caught us by surprise, which was mostly, I think becuase there are no public holidays at Easter, so you don't have a 'what are you doing for Easter' vibe going on. It was nice today to visit friends and eat some homemade, and very tasty hot cross buns. You don't see them at all up here, which is odd given the American propensity to sell and eat as much food as possible associated with any and all holidays/ special occasions. Kay's homemade ones were really great though.

Yesterday I did my first ever triathlon. An odd one it was too: 9 km ski, 5 km run and 1 km pool swim. It was a low key event organised by the local masters swim group, which a friend tipped me off to. Too bad the skate skiing was closer to ice skating with the daytime melt and nighttime freeze, and I slipped over a couple of times trying to catch the guy in front of me. I was a little afraid of the swim though. Skate skiing is very tricep/back intensive, and how much so was immediately clear with my first swim stroke - ouff! Its kind of strange too - because you obviously don't know where others are up to in the 40-lap swim. It was nice to be in race mode for the first time in ages. With no competetive sport I miss that - the attention to managing your effort for best personal performance. In the end, I was second into the pool and finshed up third. Not quite up there with Lisa's 1st out of two in a ski event at last year's learn-to-ski day, but fun to open up the throttle for a bit anyway :-)

April holds a trip to Barrow for me (13th - 20th), and later, the start of Lisa's trip to the Pribilof Islands (29th - May 5) - and then May 13 is her big graduation date. As this is an American graduation, she'll be expecting appropriate gifts - gradiation ring, cars, holidays in Hawai'i, property. That kind of thing ;-)
