Weekend #Plankton Factoid 🦠🦐
More news about the potential collapse of an ocean current, the Atlantic Meridional Overturning Circulation (AMOC) which transfers heat from the tropics to northern Atlantic, giving Europe a much milder climate, controls plankton productivity, and importantly also generates deep ocean circulation by sinking cold dense water. Winter

Is a monster web of ocean currents headed for collapse? The race is on to find out
Research ships rarely brave the Greenland Sea in winter. Early this year, scientists ventured into the ice-covered waters to capture crucial data about the planet’s future.

A phytoplankton bloom damaged habitats, deprived bottlenose dolphins of nutritious prey, and led to a sharp rise in strandings and deaths.

The new Surface Water and Ocean Topography (SWOT) satellite is crazy accurate. It can measure ocean altimetry to a mm, imaging internal waves and small sub eddies (rotating mixing zones). Tiny changes in height happen when water swirls (try it in a sink) with greater height at the edges due to centripetal force. These may be even more important for temperature &a…

Antarctica’s ocean flip: Satellites catch sudden salt surge melting ice from below
A massive and surprising change is unfolding around Antarctica. Scientists have discovered that the Southern Ocean is getting saltier, and sea ice is melting at record speed, enough to match the size of Greenland. This change has reversed a decades-long trend and is letting hidden heat rise to the surface, melting the ice from below. One of the most dramatic signs is the return of a giant hole in the ice that hadn’t been seen in 50 years. The consequences are global: stronger storms, warmer o…
