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 ...

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 ...

Hydrothermal systems at mid-ocean ridges (MOR) transfer heat, metals, and carbon from Earth’s interior to the deep ocean, ...

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" ...

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.

Wei-Jun Cai, an expert in marine chemistry at the University of Delaware, is sounding new alarm bells about the changing chemistry of the western region of the Arctic Ocean, where he and an ...

In this episode of C&EN Uncovered, host Craig Bettenhausen speaks with C&EN reporter Fionna Samuels about her recent C&EN cover story concerning ocean alkalinity enhancement as a method to combat ...

New research uses data from two sustained open-ocean hydrographic stations in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The ...

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) ...
