    Our Best Flight Yet

    Evidence of the retreat of glaciers since the last glacial maximum (check), flying over sites of ancient Inuit, Norse and present day settlements (check), and a personal recollection of my own past in this location (check).

    Ice-Coring…Almost

    The weather started to get increasingly worse yesterday, with a lot of clouds, low visibility and snow. That, of course, means that we couldn’t go out flying for two days. The forecast for the next 24 hours doesn’t look promising either. But as usual in the Arctic it’s better not to forecast — everything might…

  • Sampling Water at the North Pole

    The 2012 field season started out better than we could hope for. The weather has been great for flying out onto the ice and sampling water from the Arctic ocean. We were able to get water samples from three stations, including one at the North Pole.

    An Interactive Map of Scientific Fieldwork

    Earth Institute scientists explore how the physical world works on every continent — over and under the arctic ice, in the grasslands of Mongolia, on volcanoes in Patagonia, over subduction zones in Papua New Guinea, and on the streets of New York City.

    The group traveled by boat, motorcycle and finally by foot through the forest to reach cliffs where burials lay. At one site, 20 feet off the forest floor was a ledge protected by an overhang, where lay a row hollowed-out logs, along with ceramic jars.

    After another day spent hiding out in the Aleutian Islands, we are headed northeast towards the sea ice to attempt recovery of two oceanographic moorings. The weather is improved, only a couple of days remain for scientific study, and we are excited to hopefully accomplish one of the main goals of this cruise!

    Albany to Alert

    On the way from Kangerlussuaq to Thule we fly along the coast of Greenland, over Baffin Bay, where the Arctic starts to show its icy face. For me, Greenland is fascinating for its mild temperatures, diverse wildlife in the south and breathtaking frozen state in the north. I also like the Danish pastries served in…

    Through the Looking Glass: Peering Through the Bottom of the Ocean

    Alice stepped through the mirror to see the world beyond, and we peer through the bottom of the ocean to see what is below. Short pulses of sound from the ship are focused on the seafloor, and we listen to the echo and reverberations that return.

    Calmer Seas Ahead

    After a short break due to weather and a bit of fun with Styrofoam cups, we are back in the lab sampling phytoplankton in the Bering Sea. We are using a specialized instrument to determine how well these small plant-like creatures are able to photosynthesize in the ocean, and we continue to learn fun facts…
