Pancake ice in Andvord Bay, Antarctica. Credit: Maria Stenzel Diminishing sea ice translates to warmer ocean, more rain, and stronger trade winds. Arctic and Antarctic ice loss will account for about one-fifth of the warming that is projected to happen in the tropics, according to a new study led by […]

An international team of scientists aboard the US Coast Guard Cutter Healy and the German research icebreaker Polarstern met at the North Pole in 2015 to survey elements in the Arctic Ocean as part of the international GEOTRACES research program.

Marine chemist Ken Buesseler (right) deploys a sediment trap from the research vessel Roger Revelle during a 2018 expedition in the Gulf of Alaska. Buesseler’s research focuses on how carbon moves through the ocean. Buesseler and co-authors of a new study found that the ocean’s biological carbon pump may be […]

Coral reefs are constantly under threat from environmental stress. Credit: David Suggett The existence of coral reefs, in all their abundant biodiversity and beauty, relies largely on a complex symbiosis between reef-building corals and microalgae. This finely tuned, fragile, partnership is constantly under threat from environmental stress—most notably the twin […]

Imagine a massive mug […]

A previously unknown significant source of carbon just discovered in the Arctic has scientists marveling at a once overlooked contributor to local coastal ecosystems — and concerned about what it may mean in an era of climate change. In a Nature Communications paper released today, aquatic chemists and hydrologists from The University […]

Underwater coral drilling start. Credit: Jason Turl New international research has found a worrying change in the Indian Ocean’s surface temperatures that puts southeast Australia on course for increasingly hot and dry conditions. The work led by The Australian National University (ANU) and the ARC Centre of Excellence for Climate Extremes has […]

According to new research, the surface of Earth was likely covered by a global ocean 3.2 billion years ago. Kevin Costner, eat your heart out. New research shows that the early Earth, home to some of our planet’s first lifeforms, may have been a real-life “waterworld” — without a continent […]
