How nutrients are removed in oxygen-depleted regions of the ocean

In the course of global climate change, scientists are observing the increase of low-oxygen areas in the ocean, also termed oxygen minimum zones (OMZs)….

Can seagrass help fight ocean acidification?

Seagrass meadows could play a limited, localized role in alleviating ocean acidification in coastal ecosystems, according to new work led by Carnegie's David…

Arctic cyclone limits the time-scale of precise sea-ice prediction in Northern Sea Route?

Climate change has accelerated sea-ice retreat in the Arctic Ocean. This has various negative impacts including acidification of ocean water and potential…

An increase in Southern Ocean upwelling may explain the Holocene CO2 rise

The findings about past ocean changes could also have implications for how much atmospheric CO2 will rise due to fossil fuel burning.

Study shows ocean acidification is having major impact on marine life

Carbon dioxide emissions are killing off coral reefs and kelp forests as heat waves and ocean acidification damage marine ecosystems, scientists have warned.

Diatom ooze sediments are a large marine mercury sink

Atmospheric derived mercury is transformed in the ocean to toxic methylmercury, which is enriched in fish. Large marine predators such as tuna are strongly…
