Here is the May 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 May 2014 is copied below (Fig. 1).
Compare this to April’s map (Fig. 2) – the 24 bears from April are down to 20 and the bears are spreading out a bit from the area on the central Alaskan coast where they were originally tagged. Fifteen of these bears have satellite collar transmitters [and therefore are females] and 5 of these bears have glue-on satellite transmitters [either males or subadult animals].
Some comments on the polar bear video cam footage released June 6 by USGS and stories on it run by the media follow.
