What makes the ocean salty?

The water flowing into the ocean comes from freshwater streams and rivers. These bodies of water do contain salt. It dissolves from rocks on land. That’s because rain is slightly acidic.

A recent reversal in the response of western Greenland’s ice caps to climate change

New collaborative research from the WHOI and five partner institutions published today in Nature Geoscience, reveals that during past periods glaciers and ice caps in coastal west Greenland experienced climate conditions much different than the interior of Greenland. Over the past 2,000 years, these ice caps endured periods of warming during which they grew larger rather than shrinking.

Surviving extreme heat

A team led by Anne Cohen, a scientist at Woods Hole Oceanographic Institution, received $1.75M in funding from the National Science Foundation (NSF) to study how coral reefs survive extreme heat events caused by climate change. The multidisciplinary project taps into expertise across four WHOI departments to uncover the oceanographic and biological processes that enable corals to survive marine heatwaves.

Icebergs drifting from Canada to Southern Florida

A newly developed iceberg computer model helped the researchers understand the timing and circulation of meltwater and icebergs through the global oceans during glacial periods, which is crucial for deciphering how past changes in high-latitude freshwater forcing influenced shifts in climate.

Some Forams Could Thrive with Climate Change, Metabolism Study Finds

Oceanic deoxygenation is increasingly affecting marine ecosystems. A new paper that examines two foram species found that they demonstrated great metabolic versatility to flourish in hypoxic and anoxic sediments where there is little or no dissolved oxygen, inferring that the forams’ contribution to the marine ecosystem will increase with the expansion of oxygen-depleted habitats.

The 1.5-million-ton behemoth was on the loose.

The massive blue-tinged iceberg was headed straight for an offshore drilling platform in the Kara Sea off Western Siberia. Two smoke-billowing Russian tugs, the […]
