Continuing Deep Ocean Change In The Southern Ocean

New research by teams of Australian and US scientists has found there has been a massive reduction in the amount of Antarctic Bottom Water found off the coast of Antarctica. Comparing detailed measurements taken during the Australian Antarctic program's 2012 Southern Ocean marine science voyage to historical data dating back to 1970, scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean...

A deep-ocean current has been discovered near Antarctica by scientists, saying that it has the volume of 40 Amazon Rivers and will help researchers study the impacts of climate change on the world's oceans. The planet's climate relies heavily on the global ocean circulation pattern and the current discovered is a key part of that system. Evidence that the current exists had been detected previously by scientists, but there was no data on it. "We didn't know if it was a significant part of...

Intensifying winds in the Southern Ocean have had little influence on the strength of the Southern Ocean circulation and therefore its ability to absorb carbon dioxide from the atmosphere, according to a study published yesterday in Nature Geoscience. The Southern Ocean slows the rate of greenhouse warming by removing carbon dioxide from the atmosphere and storing it in the ocean. But previous studies raised the alarm by suggesting the Southern Ocean carbon sink is now 'saturated"˜...

A recent study has found that the Southern Ocean has proved more resilient to global warming than previously thought and remains a major store of mankind's planet-warming carbon dioxide. Oceans act as a brake on climate change by absorbing large portions of the extra CO2 released by mankind through burning fossil fuels or deforestation and experts say the Southern Ocean is the largest of these "carbon sinks." Researchers in the past have suggested the vast ocean between Australia and...

HOBART, Australia (AFP) -- Scientists have discovered dramatic changes in the temperature and salinity of deep waters in the Southern Ocean that they warn could have a major impact on global climate. Expedition leader Steve Rintoul of Australia said his multinational team of researchers had found that waters at the bottom of the Southern Ocean were significantly cooler and less salty than they were 10 years ago. He said the size and speed of the changes surprised scientists, who have long...

jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
