For Platform Hondo, there was not a significant relationship between length of 

 employment on the platfonn and frequency of marine mammal sightings, although, 

 workers who had been employed longer did see marine mammals more frequently. 

 Of the Platfonn Hondo workers interviewed, 22.2 percent had seen no large 

 whales, 11.1 percent had seen one, 55.6 percent had seen a few, and 11.1 percent 

 had seen many. All those who could name a species said they had seen gray 

 whales. 40 percent of the workers had seen the whales within 880 yards of 

 Hondo while 60 percent said the whales had been 2,640 yards away. 66.7 percent 

 of the workers reported seeing whales throughout the day, 22.2 percent saw 

 whales at dawn or dusk, and 11.1 percent could not remember what time of day 

 they had seen whales. For time of year of whale sightings, 45.5 percent of 

 the workers could not remember, 45.5 percent said winter, and 9.1 percent said 

 throughout the year. All of the workers who had seen whales said the whales 

 were alone and none of the vrarkers could remember what direction the whales 

 were moving in. None of the workers had noticed any relationship between the 

 whales and platform activity. In all cases in which whales were seen, Hondo 

 was drilling. 



58.3 percent of the Hondo workers had seen a few dolphins or porpoises, 8.3 per- 

 cent had seen one, and 33.3 percent had seen none. 62.5 percent of the workers 

 had seen the dolphins or porpoises at dawn or dusk, while 37.5 percent had 

 seen them throughout the day. None of the workers could remember the time of 

 year of the dolphin or porpoise sighting or what direction the animals had 

 been moving in. 62.5 percent of the workers said the dolphins or porpoises 

 were in groups, while 37.5 percent had seen solitary animals. None of the 

 workers had noticed any relationship between dolphin or porpoise behavior and 

 platform activity. 



All of the workers interviewed on Platfonn Hondo reported seeing many seals or 

 sea lions. All the workers said they saw the seals or sea lions throughout 

 the day and throughout the year. 88.9 percent of the workers reported seeing 

 both single animals and groups while 11.1 percent said the seals or sea lions
