thickness measurements.
The team, which Marc led and provided the logistical support for, deployed from Resolute to Nord Greenland before setting up a rustic field camp on the
sea ice for six days, during which time we mechanically drilled the
ice to measure
thickness, measuring snow depth in a grid pattern along the flight lines as well as dragging instruments along the surface that produced the same
measurements for comparison to the airborne data.

sea ice thickness and snow depth
measurements in spring, providing timely information on the state of the

Any field - or ship - based updates on
ice conditions in the different regions such as
sea ice morphology (e.g., concentration,
ice type, floe size,
thickness, snow cover, melt pond characteristics, topography), meteorology (surface
measurements) and oceanography (e.g., temperature, salinity, upper ocean temperature).

measurements of
sea ice thickness and concentration could help forecasting.

thickness and extent of summer
sea ice in the Arctic have shown a dramatic decline over the past thirty years.
Stroeve said that
sea ice volume, which incorporates
measurements of
ice extent as well as
thickness, is a more important metric than
sea ice extent alone.

sea ice thickness information provided from field
measurements and model results.
