How an Ice Age Paradox Could Inform Sea Level Rise Predictions

Feb. 15, 2017 — New research findings explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models ... read more

Global Ocean De-Oxygenation Quantified

Feb. 15, 2017 — The ongoing global change causes rising ocean temperatures and changes the ocean circulation. Therefore less oxygen is dissolved in surface waters and less oxygen is transported into the deep sea. ... read more

Scientists Report Ocean Data from Under Greenland's Petermann Glacier

Feb. 15, 2017 — Based on data from the first ocean sensors deployed under Greenland's Petermann Glacier, researchers report that the floating ice shelf is strongly coupled, or tied, to the ocean below and to ... read more

Extreme Waves Caught With Higher-Resolution Modeling

Feb. 15, 2017 — A new study shows that high-resolution models captured hurricanes and big waves that low-resolution ones missed. Better extreme wave forecasts are important for coastal cities, the military, the ... read more

Some Marine Creatures May Be More Resilient to Harsher Ocean Conditions Than Expected

Feb. 15, 2017 — As the world continually emits carbon dioxide into the atmosphere, the oceans are taking a hit, absorbing some of it and growing more acidic. Among other effects, scientists have found that coral ... read more

Feb. 15, 2017 — Ice loss from Canada's Arctic glaciers has transformed them into a major contributor to sea level change, new research has found. From 2005 to 2015, surface melt off ice caps and glaciers of the ... read more
