Marine Animal Observations 



Yearly sightings of nine types of marine ani- 

 mals were chosen to be of most probable use to the 

 oceanographic community. A graph was con- 

 structed which shows the annual temperature and 

 latitude range of the nine animals as well as their 

 weighted mean (fig. 21). The weighted mean 

 temperature was computed using the following 

 formula: 



E ^vr. 



i= I

flight, that (Iocs nut necessarily indicali' thai the 

 organism was absent from the sruvey area. 



Marine animal observations are presented in 

 this report as a by-product of ART surveys. This 

 author feels that these sightings, limited as they 

 are. will benefit those in the oceanographic com- 

 munity, both government and private, dedicated 

 to the marine biological sciences. 



ACKNOWLEDGEMENT 



The author is indebted to the pilots and crews 

 of the Coast Guard aircraft involved in the 

 monthly ART surveys and especially to the Coast 

 Guaid Oceanographic Unit technicians who ob- 

 tained these data. 



Where: T = SST of the sighting 



W — Number of sightings at that SST 



Likewise, the same formula was used for the 

 weighted mean latitude: 



Where: 5 = Substituted for (T) 



w = Number of sightings at that 

 latitude 



No attempt was made, nor should be, to attach 

 any significance to the presence or absence of any 

 marine animals. Although no observation of a 

 specific animal was made during a particular
