India Today, Washington, Jan 2017: Sea ice changes in the Arctic may delay
the annual migration of some beluga whales in Alaska by up to a month, a new
study has found. Researchers from University of Washington (UW) finds that as
Arctic sea ice takes longer to freeze up each fall due to climate change, a
population of belugas mirrors that timing and delays its migration south by up
to one month. In contrast, a different beluga population, also in Alaska, that
migrates and feeds in the same areas does not appear to have changed its
migration timing with changes in sea ice, researchers said.
