oratories provided for intercalibration of analytical procedures. 

 The interchange of data derived from reference and intercalibra- 

 tion analyses and from collected samples proved useful in evalu- 

 ating analytical methodology and in maintaining research quality. 



Atlantic Project 



Investigators at the Woods Hole Oceanographic Institution 

 (WHOI), Skidaway Institute of Oceanography, and a marine re- 

 search team from the University of Rhode Island and University of 

 Connecticut made a series of interrelated studies on the distribution 

 pattern of selected chemical pollutants in the open Atlantic Ocean. 

 Objectives of these studies were to identify or predict pollutants 

 affecting the quality of the open ocean environment and to advise 

 IDOE planning and coordinating activities of research priorities 

 indicated by these identifications and predictions. 



The WHOI portion of the project consisted of four phases: (1) 

 To collect typical samples from the North and South Atlantic; 

 (2) to establish analytical methods for measuring chlorinated and 

 petroleum hydrocarbons in the samples: (3) to measure chlorinated 

 and petroleum hydrocarbons in as many samples as possible, and 

 (4) to convene a working group to evaluate all Atlantic data in the 

 light of ecological, geochemical, and oceanographic knowledge, with 

 the objective of making further recommendations to IDOE. 



WHOI cruises, sampling programs, and tracklines are shown in 

 figure 1. WHOI scientists collected an assortment of benthic organ- 



isms from moderate depths and an assortment of mesopelagic in- 

 vertebrates and fishes from several depths between 100 and 1,000 

 m. Plankton and specific surface organisms were also collected over 

 a wide geographical range. 



The Skidaway Institute of Oceanography portion of the project 

 was concerned with the analysis of heavy metals in organisms. Open 

 ocean samples were obtained from the WHOI collections. To sup- 

 plement and extend the regional coverage obtained by WHOI's RV 

 Gosnold, inshore samples were obtained by the Skidaway Institute 

 RV Golden Isles. 



The Skidaway Institute measured metal concentrations (As, Cd, 

 Cu, Hg, Pb, Zn) in organisms from several trophic levels within 

 the marine food web. The samples, including plankton, were ob- 

 tained along the Georgia coast by WHOI's RV Knorr. Additional 

 plankton samples were provided by WHOI from samples taken 

 previously by WHOI's RV Atlantis II off the northeast coast of the 

 United States and the northwest coast of Africa. Other samples were 

 collected by Duke University Marine Laboratory's RV Eastward 

 between Beaufort, N.C., and Jacksonville, Fla. In addition to collec- 

 tions of zooplankton, collections of benthic and pelagic organisms 

 of higher trophic levels were made between Georgia and the Sar- 

 gasso Sea during several cruises of WHOI's RV Gosnold. Water 

 samples were also collected off the Georgia coast and analyzed for 

 Cd, Cu, Hg, and Zn. Figures 2 to 9 show the sampling locations
