Gulf Stream

Powerful currents driven by winds.

Temperature and Salinity

Set the density of water.

- Changes in density cause circulation.

CTD

Conductivity Temperature Depth Sensor. Measure conductivity and temperature to infer salinity.

Ocean Circulation

Mixed Layer

The density/salinity is influenced by the atmosphere.

Deep Layer

Description

Surface Density of the ocean

Density differences in the ocean can drive currents, with dense water sinking and moving from poles to the equator.

Dense water "wedge"

If there's a dense water wedge, evidence of density circulation.
