CU Boulder researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on ...

In 1888, researchers aboard the R/V Albatross began the world’s first concentrated marine research expeditions off California ...

WASHINGTON — The chemistry of the oceans is changing faster than it has in hundreds of thousands of years because of the carbon dioxide being absorbed from the atmosphere, the National Research ...

There’s more to seawater than salt. Ocean chemistry is a complex mixture of particles, ions and nutrients. And for over a century, scientists believed that certain ion ratios held relatively constant ...

March 3 (UPI) --Some 800 million years ago, changes in ocean chemistry nearly prevented the proliferation of oxygen in the atmosphere, threatening the development of complex life forms. The close call ...

The unmanned Saildrone Explorers that the University of Hawaii at Manoa are using as part of a climate change study are equipped with advanced acoustic and security camera systems and sensors to ...

RIVERSIDE, Calif. – Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" ...

(CNN) — More than half a billion years ago on a frigid, ice-covered Earth, glaciers stirred up ingredients for complex life by bulldozing land minerals and then depositing them in the ocean, according ...

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years.

Marine barite extracted from deep-sea sediment cores, seen here in a scanning electron microscope image, provides a record of variations in ocean chemistry over geologic time. (Image by Adina Paytan) ...
