The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites (including the ISS ) to higher-than-usual levels of ionizing ...
AMOC in relation to the global thermohaline circulation . The Atlantic meridional overturning circulation (AMOC) is the main current system in the Atlantic Ocean [1]: 2238 and is also part of the global thermohaline circulation, which connects the world's oceans with a single "conveyor belt" of continuous water exchange.

An expedition in May 2008 by 19 scientists [18] studied the geology and biology of eight Macquarie Ridge sea mounts, as well as the Antarctic Circumpolar Current to investigate the effects of climate change of the Southern Ocean. The circumpolar current merges the waters of the Atlantic, Indian, and Pacific Oceans and carries up to 150 times ...

A schematic overview of the Southern Ocean overturning circulation. The arrows point in the direction of the water movement. The lower cell of the circulation is depicted by the upwelling arrows south of the Antarctic Circumpolar Current (ACC) and the formation of Antarctic Bottom Water beneath the sea ice of Antarctica due to buoyancy loss.
Off the charts “crazy” heat in the North Atlantic ocean and record-smashing Antarctic sea ice lows last year are far more severe than what Earth’s supposed to get with current warming levels.
A study published Monday concluded that melting ice in Greenland caused by climate change could cause the Atlantic Meridional Overturning Circulation (AMOC) to collapse as soon as 2025, ushering ...
