New research has shown that by injecting an alkalinizing agent into the ocean along the length of the Great Barrier Reef, it would be possible, at the present rate of anthropogenic carbon emissions, ...

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 ...

A research team led by Prof. Li Mingsong at Peking University has provided new insights into the Paleocene-Eocene Thermal Maximum (PETM) and its effects on ocean chemistry. The Paleocene-Eocene ...

An international research team develops a rubric for governments and policymaking bodies to evaluate preparedness for ocean acidification. In a paper published today in the journal Environmental ...

The ocean has absorbed a significant portion carbon dioxide emissions from human activities, decreasing the pH of the water and leading to a suite of chemical changes collectively known as ocean ...

The oceans have absorbed a significant portion of all anthropogenic (CO 2) emissions (approximately a third of the CO 2 emitted from fossil fuel emissions, cement production and deforestation; Sabine ...

Playing a key role in the Earth’s climate and weather systems, as well as in the global carbon cycle, the ocean is an immeasurable force of nature. However, human activities have fundamentally altered ...

I am going to expand on the excellent introduction Hannah gave you to the science of ocean acidification (OA) in an earlier blog. In doing so, I will highlight some of the bigger picture implications ...

Ocean acidification is the lowering of seawater pH over time, as the ocean absorbs carbon dioxide (CO 2) from the atmosphere. The pH scale is used to measure how acidic or basic a water-based solution ...

Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems. In June 2025, a study found that ...
