Cruise and Sampling Plan — Offshore Waters of California 



Samples will be collected at various latitudes in the North Pacific 

 during Marine Life Research cruises in this area. As shown on the 

 track chart, Figure 6, these cruises run about 1200 miles offshore from 

 San Francisco and 2000 miles offshore from Cabo San Lucas, or more 

 than halfway to the Hawaiian Islands. Samples are being collected near 

 shore and close to known sources of pollution — San Francisco and Los 

 Angeles metropolitan areas and oil-producing areas — and from remote lo- 

 cations in the North Pacific Gyre. Attempts are being made to collect 

 sediments and benthic organisms in the same areas. Additional samples 

 are being obtained in the Bering Sea and Arctic Ocean.
