Gridded daily wind vector and wind stress fields, estimated
over global ocean from QuikSCAT scatterometer (referred as DQSCAT) data, have been updated.
A new study has found that turbulent mixing in the deep waters of the Southern Ocean, which has a profound effect
on global ocean circulation and climate, varies with the strength of surface eddies — the ocean equivalent of storms in the atmosphere — and possibly also wind speeds.
The Southern Ocean is separated from the remaining
global ocean by the surface - to - seabed Polar Front [52], which is a major barrier to dispersal of fauna to and from Antarctic waters [53].
A group of international leaders and scientists has set up an independent
Global Ocean Commission aimed at influencing U.N. efforts to preserve the high seas.
Thermohaline circulation, also called
Global Ocean Conveyor or Great Ocean Conveyor Belt, the component of general oceanic circulation controlled by horizontal differences in temperature and salinity.
Ocean oxygen levels have been dropping since the 1980s in a pattern consistent with expectations from global warming, according to a new analysis of 50 years of
global ocean data.

Global Ocean Sampling Expedition: metagenomic characterization of viruses within aquatic microbial samples.
The PDO is calculated by examining the difference in temperatures of the northern Pacific
from global ocean temperatures as a whole in order to isolate changes specific to that region.
bozzza - The differences in the Arctic are perhaps 1/4 the ocean thermal mass
as global ocean averages, small overall size (the smallest ocean), being almost surrounded by land (which warms faster), more limited liquid interchanges due to bottlenecking than the Antarctic, and very importantly considerable susceptibility to positive albedo feedbacks; as less summer ice is present given current trends, solar energy absorbed by the Arctic ocean goes up very rapidly.

Two other moons of Saturn, Titan and Enceladus, are already known to hide
global oceans beneath their icy crusts, but a new study suggests an ocean exists on Dione as well.
Changes in
mean global ocean pH / pCO2, due to uptake of anthropogenic CO2, will reduce pH (ca − 0.3 to 0.5 units / 500 + µatm), and global warming will contribute to increased sea surface temperature (+1.1 to 6.4 °C), by 2100 [1 — 4,7].
A researcher from the Finnish Meteorological Institute has been participating in a comparison of how well
