Kati points out some of the first pieces of floating sea ice sighted on our cruise. Photo by Brett Longworth My name is Kati Gosnell and I’m a graduate student in the Florida State University Oceanography Department, studying chemical oceanography. Currently trucking through my second year in the department, I’m working under the guidance of Dr. William Landing. My focus is in trace metals, so I get to clean a lot of bottles. There is a lot of trace metal action going on in my little world aboard the Research Vessel Roger Revelle. For this research cruise I am helping to sample for iron...

The National Academy of Sciences together with the National Science Foundation held a celebration on 6 April 2009 to recognize the achievements of the International Polar Year 2007-2008 (IPY). The meeting included highlights of IPY projects, including such topics as climate change, sea ice stability, Antarctic ecosystems, and people in the Arctic. Presentation videos detailing various aspects of IPY research are available on the NSF website. Posted presentations include: - "Welcoming and Opening Remarks," by James White, Ralph J. Cicerone, and Arden L. Bement, Jr.; - "How the Past Informs the Future," by Richard Alley, Pennsylvania State University;...

FSU IPY Cruise: Meet FSU Oceanography Post-Doctoral Associate Angela “Angie” Milne On deck of R/V Roger Revelle, against the backdrop of a tabular iceberg, Angie Milne, who suffers in Florida’s heat, enjoys Nature’s finest air conditioning. Photo by Charlene Grall “Hi, I’m Angie Milne, visiting FSU as a post-doctoral associate with Professor Bill Landing.” Angie’s an ocean-connected gal. Growing up in seaside Blackpool, England, Angie says, “I ‘packed in’ a job in the service field of insurance and pensions for the allure of exotic travel. This kindled my environmental interest...

Exactly one year ago today, The University of Alaska Fairbanks began a 5 month expedition to Arctic Alaska to study glacier response to climate change and their influence on the local ecosystems, as part of our contribution to IPY. The major accomplishments of that effort include: Extracting nearly 500 m of ice core from three holes in the glacier, Bringing 170 m of this back to civilization to study paleoclimate in this region, Installing thermistor strings to measure ice temperature throughout each of the three core holes, Conducted shallow coring to investigate the processes of internal accumulation on the glacier, Measured stage and discharge of the outlet stream throughout the summer,...

Ship’s log by Tom Litwin, scientist profiles by Tom Walker. Think flexibility. This is an important ingredient for travel in the Northern Being Sea. A stickler for events unfolding the way planned could find this to be a very long, nerve-wracking experience. The combined influences of wind, ice, and currents humble even the best laid plans. Fluidity in mind and action serves well those working in the ice. Today is a case in point. ...

This major navigational route passes between the Aleutian Islands of Unimak and Akun, the gateway between the North Pacific and Bering Sea. Emerging from the pass before dawn, the ship’s navigator set a course that would bring the Healy just east of St. Paul Island in the Pribilofs by 7:30 PM. ...
