The deepest areas of the Baltic Sea have always had a low oxygen content. The inflow of fresh water is actually limited by low thresholds at the entrance to the Baltic Sea. At the same time, there…

Six glaciers in West Antarctica are moving faster than they did 40 years ago. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, causing…

It is said that nothing dies of old age in the ocean, that everything gets eaten and all that remains of anything is waste. But that waste is pure gold to oceanographer David Siegel, director of the…

Research using satellite observations and ice thickness measurements gathered by NASA's Operation IceBridge is giving new insight into one of the processes causing Greenland's ice sheet to lose mass…

Temperature has been driving the fluctuating size of Peru's Quelccaya Ice Cap, not snowfall, according to a new analysis.  The Quelccaya Ice Cap is the largest ice mass in the tropics and sits…

Deep waters formed in the northern North Atlantic fill approximately half of the deep ocean globally. As you might gather, that impacts the circum-Atlantic climate and regional sea levels and soaks…

Twice in recent history, the periodic El Niño event has caused sea level drops abruptly in the tropical western Pacific. The tides remain below normal for up to a year in the South Pacific,…

Satellite observations of global sea-surface temperature have shown that a 30-year upward trend slowed in the last 15 years.  It can't be due to successful mitigation, since outside the United…

 Mesopelagic fishes like lantern fishes (Myctophidae) and cyclothonids (Gonostomatidae) live in the twilight zone of the ocean, between 200 and 1,000 meters deep.  With a stock estimated…

It's cold and snowy just about everywhere except where you expect it. Ice in northern Alaska’s lakes during winter months is on the decline, as shown by twenty years of satellite radar imagery…
