New insight into the Great Dying
A new study shows for the first time that the collapse of terrestrial ecosystems during Earth's most deadly mass extinction event was directly responsible for disrupting ocean chemistry.

A group of 17 scientists with varied backgrounds, including noted climatologist James Hansen has written a paper describing a scenario where the world's oceans rise much faster than other models have predicted—they have ...
A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false.

A new study, based on the most-extensive set of measurements ever made in tide pools, suggests that ocean acidification will increasingly put many marine organisms at risk by exacerbating normal changes in ocean chemistry ...

To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie's Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be ...

Over the last half a billion years, the ocean has mostly been full of oxygen and teeming with animal life. But earlier, before animals had evolved, oxygen was harder to come by. Now a new study led by researchers at the University ...

Ocean chemisty, also known as marine chemistry, is influenced by turbidity currents, sediments, PH levels, atmoshperic constituents, metamorphic activity, and ecology. The field of chemical oceanography studies the chemistry of marine environments including the influences of different variables.
The impact of increased carbon dioxide levels in the Earth's atmosphere on ocean chemistry from anthropogenic factors is an important area of study related to global warming and climate change. Researchers are studying how anthropogenic factors will impact and influence ocean chemistry and the related ecology of marine environments over the short and long term.
A planetary scientist using data from the Cassini spacecraft has been researching the marine chemistry of Saturn's moon Enceladus using geochemical models to look at changes through time. The presece of salts may indicate a liquid ocean within the moon, raising the possiblity of the existence of life, "or at least for the chemical precursors for organic life".
Scientists have expressed concern over increased carbon dioxide levels being absorbed into the oceans and causing acidification. The phenomenon has been implicated by scientists studying declining oyster populations on the pacific coast of the United States. One proposal suggests dumping massive amounts of lime, a base, to reverse the acidification and "increase the sea's ability to absorb carbon dioxide from the atmosphere".
Special marine environments are created around Black smokers and Cold seeps.
