Two of the seven sighting cards filled out from Platform Emmy were for dolphin 

 or porpoise sightings. One worker guessed he had seen Pacific dolphins and the 

 other thought he had seen common dolphins. Neither checked enough character- 

 istics to be sure of the identification. The worker who thought he saw common 

 dolphons apparently made two sightings between 1600 and 1700 the same day. 

 The platform was doing noma! well work and noise was estimated to be 4 to 6 

 on a scale of 10. One group of dolphins were 50 yards from the platfonn and 

 one group were 500 yards. One group was seaward of the platform and the other 

 was upcoast. Both groups were traveling upcoast. The worker indicated that 

 the dolphins changed direction towards the platform while he was watching. 

 One group had about 20 animals in it and one had 100. They did not swim 

 rapidly. They swam slowly and low in the water and milled around in the same 

 area. They did not jump high out of the water but they did jump out of the 

 water frequently. 



The worker who thought he saw Pacific dolphins made his sighting at 1430. The 

 platform was coring and the worker esimated noise as 7 on a scale of 1 to 10. 

 The dolphins were 20 yards shoreward of the platform. The animals were moving 

 toward shore and did not change direction. The worker estimated that there 

 were 75 dolphins in the herd. They swam rapidly and jumped high out of the 

 water. 



One sighting card from Emmy was for seals and sea lions. The worker said he 

 saw one sea lion, about 12 feet long, and several gray seals. "The sea lion 

 was on board for four straight days. The seals are on board regularly. The 

 sea lion didn't look like an elephant seal but was huge and aggressive." 



Two of the three sighting cards filled out for the Shell Beta Platforms were 

 for gray whale sightings. One observation was made at 1300. The whale was 

 400 yards shoreward from the platform and platform noise was estimated as 7 on 

 a 1 to 10 scale. The whale was traveling downcoast and changed direction 

 towards the platform while the worker was watching. The whale jumped out of 

 the water and slapped its tail. It swam on the surface most of the time. The 

 other gray whale observation was made from a helicopter and the whales were 

 2 miles upcoast from the Beta Platfonsis. A group of six was seen at 1530.
