Ice Age

get data

The ice age product tracks how long ice survives within the Arctic. It provides not only a distinction between first-year and multiyear ice (i.e. the seasonal and perennial ice cover), but also details on the age of the multiyear ice pack. Using satellite and buoy data, individual sea ice parcels are tracked as they form, move on the Arctic Ocean surface, and disappear (through melt or transport out of the Arctic) at 12.5 km spatial resolution in Equal Area Scalable Earth () grid. This approach is based on ice motion vectors derived using a cross-correlation technique applied to sequential daily satellite images acquired by Scanning Multichannel Microwave Radiometer (SMMR), Special Sensor Microwave Imager (SSM/I) SSM/I Sounder (SSMIS), and Advanced Very High Resolution (AVHRR) sensors. Motion vectors are then blended via optimal interpolation with drifting-buoy vectors from the International Arctic Buoy Program (IABP).

2013 Barrow Airborne Sea Ice Thickness Surveys from the Integrated Seasonal Ice Zone Observing Network (SIZONET) Project

get data

Helicopter-borne electromagnetic induction measurements (HEM) of ice thickness using the Alfred Wegener Institute's Multi-frequency Airborne Sea Ice Explorer (MAiSIE) in collaboration with the University of Alaska Fairbanks have been reld in a preliminary, quicklook format. The HEM surveys include four profiles collected in the Chukchi and Beaufort Sea northwest, north and northeast of Barrow, Alaska between March 30 and April 3, 2013. Quicklook data are available through the Advanced Cooperative Arctic Data Information Service

Unified sea ice thickness climate data record

get data

This data set targets the wealth of data that are now available from moored and submarine-based upward looking sonar (ULS) instruments, airborne electromagnetic (EM) induction instruments, and satellite laser altimeters (ICESat). These instruments offer adequate sampling dating from 1975 to establish the mean ice thickness and thickness distribution for scales generally appropriate for change detection and climate model validations.
