ON THE COVER
The cover photo was taken in August 2015
north of Svalbard in the Arctic. Sailing
through sea ice is the now retired Norwegian
Polar Institute research vessel Lance. The
expedition was part of a
2015 polar bear survey
during which polar bear
numbers were estimated in
the Svalbard et Barents Sea
regions. Taken from a heli-
copter, the photo shows
late summer sea ice that
is thin, fractured into small
floes, and covered with
melt ponds. An iceberg is
in the foreground. Photo
