Bags are packed and ready to go. April 25, 2011: We left Lamont in the afternoon to Schenectady, close to Scotia where the 109th Airlift Wing of the New York Air National Guard is located that will fly us up to CFS Alert. That unit provides extensive logistical support for allĀ U.S. science operationsĀ in theĀ arctic and…

Switchyard Project: Tracking the Arctic Seascape
Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. The multi-year Arctic Switchyard project will seek to distinguish the effects of natural climate variability from those of human-induced climate change.

A 30 year history of measuring Greenland’s Breathtaking Vistas
We flew our last science flight out of Kangerlussuaq Base (western Greenland) over the Geikie Peninsula, on the east coast of Greenland. This high priority mission had not been completed prior to this because of difficult weather in the peninsula area. The mission focus was to determine how the surface ice elevation and ice thickness…

Soaring Through the Southeastern Greenland Outlet Glaciers
Our mission was to collect some long survey lines down the center of some of Greenlandās most spectacular southeastern glaciers. The study design would require us to complete a transect across the Greenland ice sheet, fortunately at a location when the country undergoes a noticeable taper. Starting at Kangerlussuaq, our base on Greenlandās west coast,…

It takes a lot of instruments to collect ice measurements!
The Operation IceBridge (OIB) mission is a truly collaborative project with several agencies and multiple instruments involved in collecting independent measurements. The data is then analyzed concurrently to develop an understanding of the ice processes underway. The measurement of sea ice is an excellent example of how multiple methods of measurement are needed to collect…

Reflections
We are finally back from Greenland, bringing to a close the data collection piece of the spring 2010 Ice Bridge campaign. During my month-long piece in this campaign our time was split between two West Greenland base -camps, Kangerlussuaq and Thule (also known as Qaanaaq). Thule, at the northern end of Greenland, is the farthest…

The shrinking face of Jacobshavn Isbrae (Glacier)
Jacobshavn Isbrae is one of the fastest moving and most productive glaciers in the world. Scientists estimate thatĀ close to the snout (front)Ā its movement has accelerated in recent years from 20 to 40 meters a day. At the same time that the front has accelerated the glacier Ā has been rapidly retreating through ‘calving’ (large sections breaking…

āThe glacier whispers to meā
Having seen the Russell glacier from the air (May 13, 2010 blog post), several of us decided to travel the 35 miles by land from our Kangerlussuaq station with a local guide named Adam. Adam is from Southern Greenland and fills us in on local information. He notes in that area it is illegal to…
