The Pacific Ocean’s currents support a diverse ecosystem, seen here from space with green indicating blooms of photosynthesizing plankton. Warmer currents during the ice age may also have supported early human settlements.

Corals in the Gulf of Aqaba in the Red Sea. Credit: Maoz Fine A paper to be published in Frontiers in Marine Science on December 15 is calling for action to remove the oil from a decaying and inactive tanker in the Red Sea that holds approximately one million barrels of oil […]

ANIMATION Fishermen, swimmers, and seafood enthusiasts may already know the dangers of “red tides,” but a recent study in Frontiers in Climate shows that climate change is increasing the frequency of one type of highly toxic algal bloom off the US west coast. These algae produce a neurotoxin — called domoic acid — that […]

A new study helps explain how and why columns of methane gas can stream out of seafloor formations known as methane hydrates. Credit: Image courtesy of the NOAA Office of Ocean Exploration and Research, Gulf of Mexico 2017. Leakage from frozen layers was a puzzle, but a new study shows […]

Water from Canada’s Mackenzie River enters the blue Arctic Ocean in July 2012. White areas in the top half of the photo are largely sea ice, while those below are clouds over land. Credit: NASA Earth Observatory A new study shows that increased heat from Arctic rivers is melting sea […]

Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth’s climate during the last ice age, new research published in Science reveals. The discovery provides new insight into the impact rapidly melting ice flowing into the North Pacific may have […]
