Tracking polar bears in the Beaufort Sea – November 2014 map

Here is the November 2014 follow-up to my post on the July 2013 track map for female polar bears being followed by satellite in the Beaufort Sea by the US Geological Survey (USGS) – “Ten out of ten polar bears being tracked this summer in the Beaufort Sea are on the ice.”

See that post for methods and other background on this topic, and some track maps from 2012 (also available at the USGS website here). The USGS track map for November 2014 is copied below.

 Figure 1. Original caption: "Movements of 12 satellite-tagged polar bears for the month of November, 2014. Polar bears were tagged in 2014 on the spring-time sea ice of the southern Beaufort Sea. All twelve of these bears have satellite collar transmitters. Polar bear satellite telemetry data are shown with AMSR2 remotely-sensed ice coverage for 30 November, 2014."

All twelve bears (all females) are finally visible on this map, confirming my suspicion that two were so close together they overlapped. Three out of the twelve “Southern Beaufort” bears were in the Chukchi Sea at the end of November (west of Point Lay, see discussion here). If you missed it, my October 2014 post on the progress of these bears has some maps from previous years that are worth reviewing.
