Ocean level rise is known as one of the most disquieting effects of global warming, with more than three billion people living on the coast or less than 200 kilometres land inward and one tenth of the world population living … Continue reading →
Jellyfish are increasing in the majority of the world’s coastal ecosystems, according to the first global study of jellyfish abundance by University of British Columbia researchers.
Population trends of native and invasive species of jellyfish by Large Marine Ecosystem. Red increase (high certainty), orange increase (low certainty), green stable/variable, blue decrease, grey no data. Circles represent discrete chronicles with relative sizes reflecting the Confidence Index.
As ocean temperatures rise, some species of corals are likely to succeed at the expense of others, according to a report published online on April 12 in the Cell Press journal Current Biology that details the first large-scale investigation of climate effects on corals.
Researchers at Oregon State University have definitively linked an increase in ocean acidification to the collapse of oyster seed production at a commercial oyster hatchery in Oregon, where larval growth had declined to a level considered by the owners to be “non-economically viable.”
With atmospheric and oceanic CO2 levels rising and the consequent acidification of the oceans, marine life has to adapt rapidly if they want to stay around. Especially calcium carbonate skeleton building organisms are affected by the rapidly dwindling seawater pH … Continue reading →
MOC stands for Meridional Overturning Circulation, and although it refers to the same global pattern of ocean currents (‘conveyor belt’) as the thermohaline circulation, this story shows why actually MOC is the more accurate name, as it is not just … Continue reading →
