noted. General information on the various gear, samples, and observations is 

 given below, including preliminary on-ship observations regarding the impact, 

 if any, of the oil. Type of samples, data disposition, and other detailed 

 information is contained in the report on the second Delaware II cruise, 

 DE 77-01. 



Observations 



Water temperature profile . Stations: 1-11. Disposition of data: Woods 

 Hole. XBT probes were dropped at each station prior to other sampling. Tem- 

 peratures were nearly isothermal between 5°C in the shoals and 7°C in deeper 

 waters. 



Meteorological Observations . Stations: 1-11. Disposition of data: 

 Woods Hole. Observations (wind speed, barometric pressure, temperature, wave 

 height, etc.) were taken at all stations. Wind speed ranged from 12 to 27 

 knots; wave height, between 3 and 6 feet. 



Surface water samples . Stations: 1-11. Disposition of samples: Woods 

 Hole. Samples taken at every station. There was noticeable oil on the surface 

 at stations 7 and 8, although oil was not apparent in samples. A surface oil 

 sample was taken at station 7, where the oil contained sand. 



Oil slick observations . Stations: 1-11. Disposition of data: Woods Hole. 

 Oil was found at stations 7 through 8, and halfway to station 9 in 5- to 20-foot 

 wide patches occurring in rows from northwest to southeast. The oil resembled 

 floating black cloth, wrinkled from wave action. Other and more general obser- 

 vations (95 to 99% of this area) were the thin, greasy sheen with characteris- 

 tic prismatic phenomena and the odor, which was noticeable but not outstanding. 



Fish samples . Stations: 4 and 6. Disposition of samples: Woods Hole. 

 A 15-minute tow at 3.5 knots using a Yankee #36 trawl without rollers and with 

 a 1/2-inch liner was made at both stations. All species were sorted, identi- 

 fied, and measured (fork length) where applicable. Approximately 20 species 

 of fish and 10 invertebrates were taken. An oil streak 1 by 2 inches was 

 noticed on a winter flounder at station 4. All other specimens appeared oil- 

 free. 



Hydrocarbon samples . Stations: 4 and 6. Disposition of samples: Woods 

 Hole. Approximately 20 species of fish and 10 species of invertebrates were 

 frozen in foil-lined bags for hydrocarbon analysis. 



Stomach analysis . Stations: 4 and 6. Disposition of samples. Woods 

 Hole. Stomachs from little skate, big skate, spiny dogfish, cod, windowpane, 

 and ocean pout were preserved in 10% formalin for food chain contamination 

 studies. 



Maturation . Stations: 4 and 6. Disposition of data: Woods Hole. Gonad 

 development was observed and logged on standard maturation forms; no fish 

 were spawning. Various stages of ripening were observed in cod, long-horned 

 sculpin, and ocean pout.
