54 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 1 



and the Santa Catalina groups of the Channel Islands. Dredging has 

 been done at various stations off all these shores, in shallow water from 

 the dredge boat and, farther out, in deeper water, from the Velero III. 

 The beam trawl and the tangles have been used to some extent. More 

 recently the tangles have been used with the dredge regularly when the 

 larger dredge is used. Water samples and bottom samples have been taken 

 frequently and, more recently, bottom cores. 



While, in a later part of this volume, a list of the collecting stations, 

 with contributing data, will be given in chronological order, a brief de- 

 scription of each more general location, given in geographical order, will 

 serve to give definition to these locations in larger sections of the coastal 

 area. (See vol 1, no. 3, for station lists.)
