NOAA Fisheries' summer trawl survey shows Norton Sound red king crab are moving, Arctic cod numbers have dropped significantly, and Pacific cod are continuing to increase as the Northern Bering Sea ecosystem undergoes drastic change.
The fast-warming Sea of Okhotsk, wedged between Russia and Japan, is a cautionary tale of the far-reaching consequences when climate dominoes begin to fall.
In just a few years, 8 million native angasi oyster hatchlings have been placed in the waters off Victoria, South Australia, Queensland and Western Australia, on the recycled mollusc shells collected from restaurants. They've turned empty, sandy seabeds into thriving ecosystems.
Regulations have lowered mercury emissions globally, but the risks to ocean ecosystems and human health may be getting worse.
As wholesale prices skyrocket for Pacific flying squid amid a record low catch in Japan, processing companies in the "squid town" of Hakodate, Hokkaido, ar
Scientists devised a better way to calculate land elevations and their findings are dire: Far more cities will be inundated by climate change than previously thought.
Conservation groups are calling for the immediate closure of the herring fishery in the Strait of Georgia following the release of new federal government data showing a four-year population biomass decline of almost 60 per cent. “We’ve been systematically overfishing these stocks and the Gulf of Georgia fishery is the last one left,” Pacific Wild...
Similar to what has happened in B.C., tens of millions of voracious purple sea urchins have chomped their way through towering underwater kelp forests in California.
For decades, efforts have been underway to tame the effects of erosion on the Magdalen Islands, an archipelago in the Gulf of St. Lawrence. But the effects of climate change left these tiny islands vulnerable when it came to facing two powerful and unpredictable storms in less than a year.
Waters off the coast of Maine are warming faster than 99 percent of the world's oceans. That's forcing whales northward in pursuit of prey, threatening some of their already dwindling populations.
According to a recently released recap from the Department of Fish & Game, crabbing in the Norton Sound this year was underwhelming in many ways. At the beginning of 2019, ADF&G set the reg…
Under extreme heat stress, corals expel their symbiotic algae and colour (that is, ‘bleaching’), which often leads to widespread mortality. Predicting the large-scale environmental conditions that reinforce or mitigate coral bleaching remains unresolved and limits strategic conservation actions1,2. Here we assessed coral bleaching at 226 sites and 26 environmental variables that represent different mechanisms of stress responses from East Africa to Fiji through a coordinated effort to evaluate the coral response to the 2014–2016 El Niño/Southern Oscillation thermal anomaly. We applied common time-series methods to study the temporal patterning of acute thermal stress and evaluated the effectiveness of conventional and new sea surface temperature metrics and mechanisms in predicting bleaching severity. The best models indicated the importance of peak hot temperatures, the duration of cool temperatures and temperature bimodality, which explained ~50% of the variance, compared to the common degree-heating week temperature index that explained only 9%. Our findings suggest that the threshold concept as a mechanism to explain bleaching alone was not as powerful as the multidimensional interactions of stresses, which include the duration and temporal patterning of hot and cold temperature extremes relative to average local conditions.
It already has caused coral bleaching in Hawaii and may be tied to strandings of marine mammals along the California coast.
Biologists say early retreating sea ice is potentially causing vegetation productivity changes on the tundra across Alaska and the Arctic. Uma Bot, a climate variability expert with the University of Alaska–Fairbanks, says the land warms up more quickly when sea ice recedes earlier than usual. “‘Cause the tundra is temperature limited and if it has more …
The aquaculture industry has failed to bring epidemic of sea lice under control in B.C.’s Clayoquot Sound.
South winds and warm water are hitting sea ice on Arctic waters with a double whammy.
The top of the world saw record-beating average temperatures flashing through all three summer months.
The monthly temperature for the entire country was 1.7 degrees above normal.
“Whenever a seismic boat goes past and we drop our gear, the fish aren’t there. Any fisherman, or fisherman worth their salt, will tell you there’s an impact. They’ve seen it first-hand.”
