There is very typical material from 15 stations in the area, ranging 

 in depth from 20 to 554 fathoms (37 to 1,012 meters), the average 

 depth being 209 fathoms (383 meters) ; bottom temperature is given 

 at eight stations, ranging from 52.3° F. to 75.7° F. (11.2° C. to 24.2° 

 C), the average temperature 58° F. (14.4° C).
