Antarctic Ocean Currents Headed For Collapse, Driving 'mass Slowdown' In Water Circulation

Antarctic Ocean Currents Headed For Collapse, Driving 'mass Slowdown' In Water Circulation

The rapid melting of Antarctic ice poses a threat to halt deep ocean currents, which would have a negative impact on the climate, the movement of fresh water and oxygen, as well as nutrients necessary for life, for centuries, as per claims from the scientific community, reported by DW. Deep ocean currents surrounding Antarctica may slow by more than 40% over the course of the next 30 years, according to a recent study that was published in the journal Nature on Wednesday. According to the study, in a high-emission scenario, the "overturning circulation" of the ocean's deep waters will reduce by 40% by 2050, with consequences lasting "for generations to come."

Pacific islands urge Japan to delay release of Fukushima waste over contamination fears

Pacific islands urge Japan to delay release of Fukushima waste over contamination fears

Pacific island nations are urging Japan to delay the release of water from the destroyed Fukushima nuclear power plant over fears fisheries will be contaminated, the Pacific Island Forum (PIF) said on Wednesday. The Japanese government said last week that water from the destroyed Fukushima nuclear power plant could be released into the sea "around this spring or summer," raising concerns from island nations still grappling with the legacy of nuclear testing decades ago.

Deep water temperatures hit 'scary' highs in Gulf of St. Lawrence

Deep water temperatures hit 'scary' highs in Gulf of St. Lawrence

A decade-long warming trend in the Gulf of St. Lawrence continued in 2020 with deep waters reaching record highs, according to ocean climate data released Tuesday by the Department of Fisheries and Oceans. Water temperatures at depths of 200, 250 and 300 metres were higher than any measured in the Gulf since records started in 1915, hitting highs of 5.7 C, 6.6 C and 6.8 C. All were well above the normal variations.
