Bonnie Reichardt, a undergraduate student from Georgia Tech, collects data on nitrogen oxides at Summit. Her work includes taking samples from a homemade Nitrogen Oxide (NO) sampler complete with four flow controllers, two pumps, an ozonizer, a photomultiplier tube (PMT), and cooler. Basically

Jochen Stutz, a professor at UCLA, has brought his telescope to Summit to analyze gases. In a simplistic way it first looks like a Newtonian telescope with a primary mirror at the end and a secondary mirror near the eyepiece. But then you look closer and it has a Xenon arc lamp that sends a parallel

Science aboard the Healy is not just random. With Chief Scientist, Jackie Grebmeier, the research plan takes shape and becomes a coordinated effort so that everyone aboard the ship can conduct his or her research. A well-planned effort is needed since the ship is expensive to operate (I heard about

Katrine Gorham, a graduate student from University of California at Irvine, has a busy day today. The winds are blowing approx 20 kts this morning (9 m/s) and her snow chamber experiment is set up outside. She has collected 1300 ml of surface snow in a quartz cylinder and attached that container to

Katrine Gorham, a graduate student at UC Irvine, is at Summit, Greenland for six weeks conducting air sampling from a height of 1.5 meters above the surface. She samples the air every four hours (6 times a day), filling 2L canisters. There are 24 stainless steel canisters in a box and they look like

Sometime late Friday afternoon, a man in an orange suit just "suddenly” appeared at the Gambell lodge. Vince, the helicopter manager for the Healy, was there to pick several of us from Gambell and whisk us away to the Healy – someplace offshore about 50 miles south of the community. I was going

The staff always seems to be tackling big projects to improve Summit camp. One of the projects is to dismantle the DISC (deep ice sheet coring) building. Last summer the drill was being tested here at Summit and now it will be going to Antarctica to drill an ice core all the way to bedrock at the

This research project is entering the final season of a three year study. With Ann Harding working in Eastern Greenland, the research project has a field component in other countries within and near the Arctic Circle. Acknowledging that her research has continued through collaboration with several
