POWER and McCLEAVE: SIMULATION OF THE NORTH ATLANTIC DRIFT OF ANGUILLA 



FIGURE 5. — Concentration contours of American eel leptocephali after 90 d of drift (30 May). 



concentrations > 10~ 7 were now being advected past 

 the long. 40°W border of the modeled area. 



Run B' s pattern at 5 mo was similar to those just dis- 

 cussed, but the main concentration of leptocephali 

 was farther offshore of Florida and more broadly dis- 



tributed (Fig. 6B) because the larvae were started in a 

 region of weaker currents. There was a greater degree 

 of northward transport from the main concentration, 

 so that leptocephali joined the Gulf Stream at higher 

 latitudes than in other runs.
