From the coast to the deep sea, changing oxygen levels affect marine life in different ways

Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels ...

A new electrochemical approach could reduce ocean acidity and remove carbon in the process

In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The ...

East coast mussel shells are becoming more porous in warming waters

Researchers at the American Museum of Natural History have found that over the last 120 years, the porosity—or small-scale holes—in mussel shells along the East Coast of the United States has increased, potentially due ...

Coral reef microbes point to new way to assess ecosystem health

A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.

Video: Is there a quick fix for ocean acidification?

Acidification is threatening the ocean's ability to pull carbon dioxide out of our atmosphere, so scientists and startups are looking to ocean-sized antacids to raise its pH.

Study reveals giant store of global soil carbon

Soil carbon usually refers only to the organic matter component of soils, known as soil organic carbon (SOC). However, soil carbon also has an inorganic component, known as soil inorganic carbon (SIC). Solid SIC, often calcium ...

Impact of climate change on marine life shown to be much bigger than previously known

Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. This is the conclusion of a study co-led by NIOZ marine biologist Katharina Alter, based on a new analysis ...

Heat stress from ocean warming harms octopus vision

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.

A natural history of the Red Sea and the uncertain future of its corals

Early in May 2023, a small team of marine biologists arrived in the Saudi Arabian city of Jeddah. They'd flown into the local airport from Guam, the United States, Portugal, Spain and Japan, and they'd soon rendezvous with ...

New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process

In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The ...
