Switchyard Project: New Sampling Record
On May 10, we celebrated the sampling of our 10th station yesterday. These are more stations than we were ever able to get water samples from. Because of the ongoing good weather, we will certainly get one more station today, and hopefully many more during the next couple of days. So watch the posted video and celebrate with…

Dealing with Mother Nature
Working in the poles we are constantly reminded of our dependence on meteorology, and this project has dealt us a variety of different weather considerations. The most obvious is the weather we experience at the base. Storm season in Thule lasts from the 15th of September to the 14th of May; in other words encompassing…

Transporting Ice From Greenland’s Deep Interior
The North East Ice Stream is a fast-flowing glacier transporting ice from deep in the interior of the Greenland Ice Sheet out to the coast (see image showing a deep penetration into central Greenland). When it reaches the coastline it feeds 79 N Glacier. This area is heavily crevassed, evidence of the rapid ice flow.…

Switchyard Project: Rescue Operation
Four people who tried to ski from the North Pole to Greenland got stuck on the ice and ran out of food. Since our team was out on the ice for sampling close to their location, we stopped sampling and picked them up.

Petermann Glacier: At a glacial pace?
We are beginning our focus on the land based ice of northern Greenland. Flying out of Thule places us close to Petermann Glacier situated in Greenland’s northwest corner. The focus of our first flight of this phase of the project (the overall 29th flight of the season!) is Petermann Glacier. Perhaps Greenland’s most newsworthy glacier…

Switchyard Project: Day 1 – Alert, Alert, Alert
The first day of our operation is usually filled with a lot of work preparing and testing the instruments we brought up here, preparing the airplanes, loading our equipment into the planes, setting up the equipment in the laboratory and preparing the sampling containers. Since our operation requires drilling holes through the sea ice, we…

Can Big Earthquakes Disrupt World Weather?
The recent earthquake in Japan shifted the earth’s axis by half a foot. You may be wondering if that’s enough to change earth’s weather. No, not really, says Jerry McManus, a climate scientist at Columbia’s Lamont-Doherty Earth Observatory. Earthquakes unleash a tremendous amount of energy, but not enough to upset the energy balance of earth’s…

Switchyard Project: In Transit…Part 2
April 27, 2011: We spent the night in Thule in the North Star Hotel. Before we could leave Thule the crew had to load the cargo back into the C130. Equipment is loaded onto palettes, and these palettes are loaded through the rear door into the plane. A C130 can handle four palettes with two tons of cargo…

By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
