Figure 7. Sample field experiment plan. Bottom panel shows an archived AVHRR false color image of the study region. The thick white lines are the Topex/Poseidon ground tracks, and the thin white lines are the historical mean and meander envelope of the SST front (P. Cornillon, personal communication). The red lines are the ship tracks of the R/V Cape Henlopen. Red x's are plotted every 24 hrs out of port. The dashed blue line between Bermuda and NJ is the ship track of the M/V Oleander, with x's at New Jersey and every 24 hrs out of New Jersey, and o's at Bermuda and every 24 hrs out of Bermuda. The cyan x's and *'s are NOAA bouys. The Dashed blue line out of Norfolk is the ship track of the M/V Godafuss. Top: the climatological mean SSS along the ship track. Dashed lines indicate turning points in the cruise pattern (Courtesy S. Howden, GSFC).
