This page is primarily focused on the results of the Sargasso Sea research project. It discusses both the cyclonic and anti-cyclonic eddies and their transport of nutrients.

This page discussed how eddies may actually account for a significant percentage of global oceanic primary production mainly from zooplankton, in the open ocean.

This page describes a research study that was completed by the University of CapeTown that studied how eddies help transport sea water from the Indian Ocean to the South Atlantic.

This website talks about how satellite use IR sensors d to measure the temperature across large expanses of the ocean surface. This data can then be used to permit scientists to observe ocean circulation and locate major ocean currents.
- GYRES AND EDDIES - KISSING COUSINS of CURRENTS. Ocean World.
http://oceanworld.tamu.edu/students/currents/currents4.htm
This website would be quite useful in a middle school setting. It describes how Eddies and Gryes form. The site has many useful drawings and maps that would help students gain an understanding of these events.

This page discusses how bathymeric data is used to model the effects of Gulf Stream upwelling in the North Atlantic.
- Temperature and Salinity Variability in Thermohaline Staircase Layers. Massachusetts Institute of Technology

The page discussed if eddies an important contributor to subduction in the eastern subtropical gyre. They used numerical models with observations to produce a state estimate of the ocean circulation.
