Argument for designing an ocean monitoring network based on satellite-derived chlorophyll-a concentration?

The idea is to design an integrated marine monitoring network by surveying in parallel the chlorophyll-a and the other oceanography parameters, which are either trophically related with the ...

How much does the Meridional Overturning Circulation strengthen the Gulf Stream?

While the Gulf Stream is a western boundary current (WBC), one professor told me that the Gulf Stream is stronger than it should be just by using theoretical calculations of WBC. How much is the heat+...

What are black-hole ocean eddies?

How are they formed? Why are they so stable? What finally breaks them apart and what is their typical lifespan? Why are fluid particles trapped inside it and advected towards the center? How do they ...

Availability of mean squared slope or wave spectra data for the sea surface

The mean squared slope is a property of the sea surface that is often sensed by microwave radars [1] [2]. While spatial data for sea surface salinity, sea surface height, and significant wave height ...

How cold would the Earth have to be for the oceans to freeze entirely?

I imagine it is difficult for the ocean to freeze solid due to the low freezing point of salt water and the insulating effect of the formation of sea ice over the cool but still liquid ocean water. ...

Spatial variability in ocean surface winds

For the near-surface winds over the ocean, many model products and satellite footprints have spatial resolutions on the order of tens of kilometers. I'm interested in knowing how much the winds (both ...

Why do Mediterranean main currents surrounding landmasses turn counter-clockwise?

At North Hemisphere, main superficial currents turn clock-wise, because of Coriolis Effect. I would expect on Mediterranean Sea to have currents turning in the same sense, but, surrounding landmasses,...
