These entities are mapped by the OSCAR dataset.
Instruments used to measure these things include a sonar-like device called an ADCP. Deep examples of these entities are the subject of the Argo project. These entities are mapped by the OSCAR dataset. Gradients of the Coriolis force cause the "westward intensification" of these entities. Wind forcing results in these entities moving 90 degrees to the wind in Ekman transport, and these entities have geostrophic (*) balance when pressure gradient forces balance the Coriolis force. Differences in temperature and salt concentration drive these entities in the thermohaline circulation. Their total flux is measured in Sverdrups, and examples of them include the Kuroshio and Antarctic circumpolar. For 10 points, name these flows of water through earth's largest bodies of water.
