zooplankton

The sudden collapse of carbon sinks was not factored into climate models – and could rapidly accelerate global heating

Zooplankton vital for fish on B.C.’s southern coast are lining their guts with synthetic microfibres shed and flushed out to sea when we wash our clothes, causing big ripple effects for marine life.

In a dark, unexplored layer of ocean, a hidden cache of fish might play an unexpected role in our climate’s future. It seems like a bad time for a new fishery.

Whales seem to find food by sniffing for a chemical cue. Scientists are hoping to turn this into an early warning system to help save the imperilled species.

The algae Melosira arctica is the foundation of the food chain, and its contamination could have major consequences for ecosystems and the climate.

Richard Kirby, a marine biologist based in Plymouth, England, was looking at zooplankton wriggling under a microscope when he spotted something else: shreds of plastic pieces interlaced with the tiny creatures.

Scientists who study the endangered North Atlantic right whale are cautiously optimistic about the current breeding season after nine calves were spotted during its first few weeks.

A fishing boat that sank with nearly 10,000 litres of fuel on board near the Canada−U.S. marine border went down in one of the worst possible places for endangered orcas, an ocean pollutants expert says.

The realization that turbulence created by deepwater wind turbines could upset the spring phytoplankton bloom has researchers warning the rapidly emerging industry to proceed with caution.

The federal Fisheries Department is trying to shed more light on seals' impact — or lack thereof — on Newfoundland and Labrador's struggling cod stocks.

Federal fisheries experts are painting a devastating picture of the challenges facing Pacific salmon and point to climate change as the main culprit.

The bodies of the tiny organisms lock away enormous amounts of carbon dioxide, and they’re in danger.

Researchers were in northwestern Ontario on the weekend spilling diluted oilsands bitumen and crude oil into a lake to study how the ecosystem, from microbes to fish, responds.
