A new study links rapid deoxygenation in the Gulf of St. Lawrence to two powerful currents: the Gulf Stream and the Labrador Current.
Commercial salmon fisheries in Washington, Oregon, and California are eligible for a portion of $20 million in disaster assistance after federal officials determined fishery failures occurred.
The Gulf of St. Lawrence has warmed and lost oxygen more rapidly than almost anywhere else in the Earth's oceanic waters due in part to climate change, raising the possibility that it could soon be unable to fully support marine life, according to a new study.
Scientists say the threat from sargassum is as serious as rising sea levels and hurricanes.

The Western New York landscape is now strewn with dead and dying Ash trees. The evidence of the Ash Borer's destruction is crystal clear, and our environment may never be the same.
The smoke has pushed pollution in Calgary and other cities to dangerous levels, and cast an unsettling, spooky haze over almost every part of B.C.
Scientist warns of "seagrass crisis" in Caribbeans MEXICO CITY (Rahnuma): Massive quantities of Sargassum seaweed are invading Caribbean beaches mostly thanks to global warming and countries should work closely with scientists for a sustainable solution, said a researcher at a leading Mexican university on
ALBANY - After years of trying to slow a voracious Chinese beetle that is decimating ash trees, state environmental officials are waving the white flag: The Department of Environmental Conservation dropped a logging quarantine, and said it might be time to cut healthy trees still uninfested. In a brief notice posted online Wednesday, the DEC repealed logging restrictions that had failed to contain the spread of the emerald ash borer (EAB) by limiting shipments of ash. The state created the quarantine in 2015 to slow the insect, which is a shiny green beetle about the size of a penny. The borer likely will ultimately bring about the end of the state's 700 million ash trees - down from earlier estimates of 900 million ash trees before the beetles' arrival - and forever change an industry that uses ash to produce bats for major league baseball.

Alberta consistently sees an average of 1400 wildfires each year however, the increased economic costs due to firefighting, equipment, damaged properties, evacuations, insurance, remote housing and food can be a challenge.
The regionally endemic Galapagos Grouper, locally known as bacalao, is one of the most highly prized finfish species within the Galapagos Marine Reserve (GMR). Concerns of overfishing, coupled with a lack of fishing regulations aimed at this species raises concerns about the current population health. We assessed changes in population health over a 30-year period using three simple indicators: (1) percentage of fish below reproductive size (Lm); (2) percentage of fish within the optimum length interval (Lopt); and (3) percentage of mega-spawners in the catch. Over the assessed period, none of the indicators reached values associated with healthy populations, with all indicators declining over time. Furthermore, the most recent landings data show that the vast majority of the bacalao caught (95.7%,) were below Lm, the number of fish within the Lopt interval was extremely low (4.7%), and there were virtually no mega-spawners (0.2%). Bacalao fully recruit to the fishery 15 cm below the size at which 50% of the population matures. The Spawning Potential Ratio is currently 5% of potential unfished fecundity, strongly suggesting severe overfishing. Our results suggest the need for bacalao-specific management regulations that should include minimum (65 cm TL) and maximum (78 cm TL) landing sizes, slot limits (64–78 cm TL), as well as a closed season during spawning from October to January. It is recognized that these regulations are harsh and will certainly have negative impacts on the livelihoods of fishers in the short term, however, continued inaction will likely result in a collapse of this economically and culturally valuable species. Alternative sources of income should be developed in parallel with the establishment of fishing regulations to limit the socio-economic disruption to the fishing community during the transition to a more sustainable management regime.
For decades, the crab piled up in fishing boats like gold coins hauled from a rich and fertile sea. But the very ocean that nursed these creatures may prove to be this industry’s undoing.Scientists fear ocean acidification will drive the collapse of Alaska's iconic crab fishery.
