In recent years, the Southern Ocean has undergone one of the most dramatic environmental shifts observed anywhere on Earth.

Using a design inspired by one of the ocean's best sailors, a team of scientists at the Johns Hopkins Applied Physics Laboratory is developing a low-cost sensor for ocean observations. The sensors are ...

A study published Monday in the Proceedings of the National Academy of Sciences found that increases in salinity in seawater ...

Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ...

Using salinity as a tracer can show why the cold pool erodes during the summer season when stratification (or, ocean layering) is high and where these changes come from.

If swimming in it isn't enough, you're reminded how salty the ocean is when you accidentally swallow some. Here's where that salt water comes from.

A Jacksonville professor is part of an international group of researchers warning of another threat from climate change: salinity levels in the ocean.

New research explores the wide-ranging consequences of record low summer sea ice in Antarctica. From more ocean warming to extra icebergs, it’s bad news we must hear.

As water evaporates from the ocean’s surface, it leaves its salts behind, making the ocean surface just a little bit saltier. By monitoring changes in sea surface salinity, scientists have a ...

Increased salinity also changes density which controls things like ocean circulation. Scientists are beginning to see changes in the way water moves around the Earth.

Which ocean is the saltiest? Of the world’s five ocean basins — Pacific, Atlantic, Indian, Southern and Arctic — the Atlantic has the highest salinity, says the National Weather Service.
