“[Here is a] climatology near-surface currents and temperatures for the world, at monthly and one-quarter degree resolution, derived from satellite-tracked surface drifting buoy observations.
Animations of these currents are available [also at aoml.noaa.gov/phod/gdp/animati].
Maps of these currents in various regions can be seen on the Ocean Surface Currents web site [oceancurrents.rsmas.miami.edu/

A photo of the catastrophic flooding in Spain. A street is completely filled with piles of dozens of cars. & ppl in the U.S. be like: "Those climate protestors blocking streets should be arrested and put in jail. 21 states allow prison sentences for peaceful protestors, so if they stop us from driving on the roads, put them in prison."

A photo of a street in Spain, filled with piles of dozens of cars, after catastrophic flooding. The caption reads "Those climate protestors blocking streets should be arrested and put in jail. Twenty-one states allow prison sentences for peaceful protestors, so if they stop us from driving on the roads, put them in prison."

#Upwelling zones are particularly important to ecologists because these zones provide nutrients to the surface layers and are relevant to #ClimateChange research. Upwelling of meridional overturning circulation (MOC) has been notoriously difficult to observe, though known to exist as part of #ocean conveyor belt circulation. A new study using dye tracking suggests that bottom topography of submarine canyons directs deep-sea #currents upward.

image/png A map shows the pattern of thermohaline ocean circulation also known as "meridional overturning circulation" with red surface currents turning to blue at the poles and sinking. This collection of currents is responsible for the large-scale exchange of water masses in the ocean, including providing oxygen to the deep ocean. The entire circulation pattern takes ~2000 years. https://en.m.wikipedia.org/wiki/Thermohaline_circulation

Each year, on average 27.7 million tons of Saharan dust, carried on wind currents across the Atlantic, drop into Amazonia, bringing vital phosphorus from the Bodélé Depression in Chad, an ancient lake bed. Amazonia's plant life needs this transoceanic fertilization. nasa.gov/centers-and-facilitie
