Tree-Ring Science in a Log Yard?
The cool, snowy weather really put a crimp in our plans. Dario, Tuncay, Cengis, and others spent two days trying to find potential sampling locations before Nesibe and I arrived. Even though it had been well above freezing during the day and above freezing at night, the snow had only retreated so far in the…

Ice cores…finally
Today I got another chance to go out with team CASIMBO to drill ice-cores. The weather was beautiful with no wind, a few clouds, bright sunshine and a balmy temperature of about 5 degrees F. When I first saw sea ice near Alert a few years ago, I was very surprised. It wasn’t anything like…

Drilling Ancient Mud from Seafloor No Easy Task
Yesterday we left our first study region with new samples from the seafloor and a healthy respect for the ocean currents that can erode sediment deep in the ocean. The seafloor we surveyed was heavily eroded and we had to look carefully before finding sites that were promising enough to try sampling. Even then we…

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.

In Log Coffins, First Glimpses of a Mysterious Asian People
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.

On the Move
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!
