Cannot do my April 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.
“Tracking Polar Bears by Satellite” has not yet been updated with the April map, which is unusual for this late in the month (it is usually updated within the first few working days of every month). Perhaps the sea ice data they use was late being processed?
Here is the map for March, discussed previously here.
Figure 1. Movements of 5 satellite-tagged polar bears for the month of March, 2014. Polar bears were tagged in 2013 on the spring-time sea ice of the southern Beaufort Sea. All 5 of these bears have satellite collar transmitters. Note that the dots with the polar bear icons are the end points (end March), while the other end of the string is their position in early March. These are the same 5 females that were present in January. Click to enlarge.
Previous dates for tracking available here.
