We compare the observations of arctic sea ice thickness estimates from satellites with in situ observations – collected by submarine cruises and moorings under the sea ice, by direct measurement during field camps, by electromagnetic instruments flown over the sea ice, and by buoys drifting with the sea ice – to provide a careful assessment of our capabilities to monitor the thickness of sea ice.

When doing research in the Arctic the elements are big challenge not just for the humans working there but also for the instruments used to collect data. Ignatius Rigor has set up a testing site outside of Barrow, Alaska to monitor an array of instruments and test their reliability and accuracy. Watch the video to learn more about the project.

This project aims to measure the time history of summer warming and subsequent fall cooling of the seasonally open water areas of the Arctic Ocean. Investigators will focus on those areas with the greatest ice retreat i.e., the northern Beaufort, Chukchi, East Siberian, and Laptev seas. Their method will be to build up to 10 relatively inexpensive ocean thermistor string buoys per year, to be deployed in the seasonally ice-free regions of the Arctic Ocean. Arctic-ADOS buoy data will be provided to both the research and operational weather forecasting communities in near real time on the International Arctic Buoy Program (IABP) web site.

Images of massive chunks of ice collapsing from Greenland’s glaciers into the ocean have become emblematic of a changing climate and the need to drastically reduce global carbon emissions.University of Maryland Assistant Professor of Art Cy Keener is working to characterize some of these icebergs—capturing their unique identities and the ways they change as they drift in the sea.His collaborative “Iceberg Portraiture” series is part of an exhibition now on view at the National Academy of Sciences (NAS) in Washington, D.C., which Keener created with landscape researcher Justine Holzman, climatologist Ignatius Rigor and scientist John Woods. It’s the result of almost…
