  • Communicating Arctic Science, from a science meeting to a high school classroom

    Last week (May 18-23) marked the first annual Association for the Sciences of Limnology and Oceanography’s Joint Aquatic Sciences Meeting (JASM). While the Polaris showing at the JASM wasn’t quite as impressive as AGU, a solid group of Polaris students and related researchers made excellent presentations, including the entire (three member!) Carbon Bomb team: Rob Spencer, Paul Mann, and myself.…
  • Northern lights

    The seasonal difference between doing fieldwork in Siberia in summery July and a now autumnal September is obvious in low temperatures and bug-free conditions. Plus the added bonus: dark nights and Aurora Borealis, a.k.a. the Northern Lights.
  • Fieldwork in the Siberian autumn

    In our first four days of being here, we’ve sampled about 15 sites, spanning streams and rivers all the way from Duvannyi Yar to the tundra. With summer coming to a close, we’ve decided to take advantage of the warm and mosquito-free days that this Siberian autumn has offered us with a whirlwind of boating and sampling adventures.
  • Record breaking in Yakutsk

    We experienced this first hand as we exercised (and nearly ran out of) patience in the form of a 100-hour delay in Yakutsk – a new Polaris record!
  • Back to the promised land

    With three red-eye flights 4 hours in front of me, the GRE 4 hours behind me, and a final pile of fruits and vegetables in front of me, I feel ready to take off for the land of moose meat, confusing weather, big bugs and epic science.
  • Dowdy et al 2012 AGU

    Dowdy, K. I., Vonk, J. E., Mann, P. J., Zimov, N., Bulygina, E., Davydova, A., Spencer, R. G. M., Holmes, R. M. 2012. Ancient Yedoma carbon loss: primed by ice wedge thaw? American Geophysical Union, fall meeting, San Francisco, California. [download pdf]
  • Ancient Yedoma carbon loss: primed by ice wedge thaw?

    An excellent location to study Yedoma is Duvannyi Yar, an eroding cliff on the shore of the Kolyma River in northeast Siberia. Here, melting ice wedge water drips down to form streams, which pick up Yedoma soil on their way to the Kolyma River below.
  • Science is life at the Northeast Science Station

    Spending every waking (and sleeping) moment with like-minded ecologists really allows us students to come into our own as scientific beings.

    After many weeks of having The Beatles' "Back in the USSR" put a bigger smile on my face than usual, the day is finally here to depart on my Russian adventure!
