Arctic Ocean now less salty

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.”   

Unlocking the secrets of the Greenland Shark

One of the dreams of any naturalist is to be the first to find and detail the life of a hidden or unknown animal first hand. Since 2003, scientific divers with the Greenland Shark and Elasmobranch Education and Research Group (GEERG) have begun to unravel the mysterious life of the Greenland shark, which at over seven meters in maximum body length and exceeding a ton in weight, is the second largest carnivorous shark after the great white.
