Challenger, Argo Data Show Ocean Warming Over 100 Years

摘要

A study published in April contrasting ocean temperature readings of the 1870s with temperatures of the mod- ern seas reveals an upward trend of global ocean warming spanning at least 100 years. The research, led by Scripps Institution of Oceanography physical ocean-ographer Dean Roemmich, shows a .33° C average increase in the upper portions of the ocean to 700 meters depth. The increase was largest at the ocean surface, .59° C, decreasing to .12° C at 900 meters depth.
