Zooplankton are a critical component of marine ecosystems. They link phytoplankton production to higher levels of the marine food chain (which the scientists call trophic levels), including ...

Scientists have discovered that deep-sea mining plumes can strip vital nutrition from the ocean’s twilight zone, replacing natural food with nutrient-poor sediment. The resulting “junk food” effect ...

The ocean is losing its greenness, a new study has found: Global chlorophyll concentration, a proxy for phytoplankton biomass, declined over the past two decades, especially in coastal areas.

Mathematicians have solved a physics puzzle using backyard sprinklers. Experiments with silly sprinklers clarified how ...

Scientists have been aware for some time that whales contribute to marine ecosystems by "recycling" nutrients. However, the exact impact on ocean productivity was unclear and had not been studied ...

Marine ecosystems and fisheries are vital to global food security, providing essential nutrients and livelihoods to millions ...

Researchers say the Arctic Ocean crossed a biological tipping point in 2009, when nitrate levels in the water suddenly started dropping due to a drastic reduction in sea ice extent.

A spectacular fossil trove on the Arctic island of Spitsbergen shows that marine life made a stunning comeback after Earth’s greatest extinction. Tens of thousands of fossils reveal fully aquatic ...
