Arctic

Researchers have found that the Arctic Ocean is becoming less salty, because the amount of freshwater flowing through the Bering Strait into it has increased by 40 to 50 percent, over the past 30 years.

This finding is based on a new study by the University of Maryland Center for Environmental Science. According to lead author Lee Cooper, “This could have a lot of downstream implications for how the Arctic Ocean works and connects with climate and related processes, including the intensity of mixing in the North Atlantic.”   

Two ships, HMS Erebus and HMS Terror, were part of Sir John Franklin's doomed expedition in 1845 to find the Northwest Passage from the Atlantic Ocean to Asia.

The ships disappeared after they became locked in ice in 1846 and were missing for more than a century and a half until last month's discovery by a group of public-private searchers led by Parks Canada. It was not known until now which of the two ships had been found.
