Arctic Ocean more vulnerable to human-induced changes than Antarctic Ocean

Arctic Ocean more vulnerable to human-induced changes than Antarctic Ocean
A team including Dalhousie Oceanography Professor Helmuth Thomas and recent Dalhousie Oceanography PhD graduate Elizabeth Shadwick found evidence suggesting that the Arctic Ocean is more vulnerable to human-induced changes than the Antarctic Ocean. After comparing sites in both oceans, they found the Arctic site to be more acidic, warmer during the summer months, and have fewer nutrients; those disparities account for the differences in vulnerability. The results were published in Nature Scientific Reports. http://phys.org/news/2013-08-arctic-ocean-vulnerable-human-induced-antarctic.html#nwlt
