The cruise plan (updated 09-Aug-2002) is available here as a MS Word doc or here as a text file.
Cruise participants should read this for some tips on going to sea on the R/V Gyre.
Recent Sea Surface Height altimetric maps from Bob Leben's group at CCAR of Colorado University maps show the series of highs and lows in the Gulf which can be interpreted much like weather maps to indicate the direction and strength of the currents.
If you must communicate with someone on board the R/V Gyre during the cruise the information here will help you do so.
