Annual Sea Ice Cycle over Northern Canada

Visualizations by Alex Kekesi Released on September 13, 2006

Over the course of a year, sea ice in northern Canada pulsates down into the Hudson Bay and retreats northward in the summer months. In the winter months where the sea ice extends down into the bay, polar bears wander onto the ice in search of food. As summer approaches and the sea ice melts, the bears wander back onto the mainland until the next winter. Data for this animation was gathered from the Aqua satellite's Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E). Aqua is a NASA satellite and the AMSR-E instrument onboard was provided by the Japan Aerospace Exploration Agency (JAXA).
