Technologies shine spotlight on climate role of undersea canyons

Unprecedented high-resolution data from undersea canyons off Vancouver Island's west coast is bringing new understanding of the importance of these canyons as rapid-transit corridors for carrying carbon from the ocean surface ...

Radioactivity lingers from 1946-1958 nuclear bomb tests

Scientists have found lingering radioactivity in the lagoons of remote Marshall Island atolls in the Pacific Ocean where the United States conducted 66 nuclear weapons tests in the 1940s and 1950s.

Fish food for marine farms harbor antibiotic resistance genes

From isolated caves to ancient permafrost, antibiotic-resistant bacteria and genes for resistance have been showing up in unexpected places. As scientists puzzle over how genes for antibiotic resistance arise in various environments ...

Sub-zero waters a barrier to oil spill recovery

Sub-zero temperatures in the deep waters of the North Atlantic would significantly hamper the ability of oil-eating bacteria to help the ocean recover from a major oil spill, according to new research.

Researchers investigate the ocean's deep biosphere

Bundled in layers of blankets for warmth, Laura Zinke settled in for a two-hour ride to the bottom of the ocean. The temperature dipped significantly once she and her colleagues passed the depth still touched by sunlight, ...

Isotopes with ocean circulation information

The distribution of a radioactive thorium isotope is important in multiple aspects of oceanograpy. In his new publication, Yiming Luo has revisited the issue on processes influencing the distribution in the water column.

Four weeks at sea for climate research

A complex system of surface and deep water currents circulates in the North Atlantic, between Iceland and the Azores, called the Atlantic Meridional Overturning Circulation (AMOC). The Gulf Stream, which transports heat to ...
