Figure 3. Atlantic environmental quality baseline data-acquisition cruises. 



Organisms were collected on these cruises by dip-netting (Sargassum, 

 flying fish, triggerfish, squid), by hook and line (dolphin-fish, sharks) by 

 standard plankton nets, by Isaacs-Kid midwater trawls and dredges. Pre- 

 cautions taken against contamination included the use of residue-free 

 ethanol (from ethylene hydration) to wash implements and containers, 

 avoiding plastics, and preservation by freezing in glass or in washed 

 aluminum.
