A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise. The new research found glaciers outside of the Greenland and Antarctic ice sheets, repositories of 1 percent of all land ice, lost an average of 571 trillion pounds (259 trillion kilograms) of mass every year during the six-year study period, making the oceans rise 0.03 inches (0.7 mm) per year. This is equal to about 30 percent of the total observed global sea level rise during the same period and matches the combined contribution to sea level from the Greenland and Antarctica ice sheets.
The fin whale is the second-largest animal ever to live on Earth. It is also, paradoxically, one of the least understood. The animal’s huge size and global range make its movements and behavior hard to study.
International research has suggested that many coral species won’t survive beyond the end of this century, but marine biologists at Victoria University are offering an alternative scenario.
The 2013 spring and summer red tide reason in New England is expected to be “moderate” according to NCCOS’s partner, the Woods Hole Oceanographic Institution (WHOI), forecast last month. Ocean and weather data from the Gulf of Maine buoys play an important role in this forecasting effort. When developing this new red tide forecast system, scientists depended on historical data from the buoys to develop and verify the model.
Combining recent advances in remote sensing and aerial survey, a new system for airborne current measurement has been developed to bridge the gap between satellite- and vessel-based ocean current measurements. ROCIS, the Remote Ocean Current Imaging System, combines Fugro expertise in airborne survey and operational oceanography with state-of-the-art technology and oceanographic research from Areté and Associates.
