cruises carried out on private- yachts, on which a certain amount of 

 biological collecting is c-one, for oceanographic work is in this 

 case only incidental. Fur then.iore . it is difficult to estimate 

 whether the increasing frequency of such undertakings reflects any 

 corresponding appreciation of the value of marine research, or 

 whether they simply evidence the inter...3t that some persuasive

B. SEA-SIDS LAB0RAT0RI2S, A3 HEADQ,UiiRTW:S FOR OCSANOGRAPHIG 



INV2STIGaT1CN3 



In addition to the ship work just sammcirized , certain fields 

 of investigation, especially in oceanic biology, and in chemistry, 

 are now being prosecuted at sea-side laboratories on both coasts, 

 and at oth^r'stations, the more important of which must be mentioned. 



1. Atlantic Coast 



On the Atlantic Coast these phas'^s of Oceanography are 

 being actively attacked at the ft.tlantic Biological Station of the 

 Biological Board of Canada at St. Andrews, and Y/ork in this 

 direction is projected for the new marine laboratory of the Board 

 at Halifax, W. S. The station-proirrs-r. here incluU-s investigations into 

 many fields where fisheries Questions are most obviously dependent 

 on the underlying problems of organic production in the sea. It is 

 not necessary to list these here; they have to do chiefly with the 

 general physiology of marine organisms, and (on the oceanographic 

 side) include studies on the penetration of light; on the circulation 

 of the water as making the dissolved food stuffs available for 

 plant production; on the sources of these food stuffs and, (at St. 

 Andrews) a very detailed study of tidal currents as agents in main- 

 taining the great organic fertility of that region. 



The Mt. resert Island Biological Laboratory has, during the 

 past year, undertaken a joint exploration of the local waters, in 

 cooperation with the Buffalo Society of Natural History, to include 

 both the Biological and the Physics-Chemical aspects. The Woods Hole 

 and Beaufort Laboratories of the United States Bureau of Fisheries 

 and the Marine Biological Laboratory at Woods Hole are also centers 

 for such activities. 



At the Woods Hole Laboratory of the Bureau of Fisheries, where 

 for administrative reasons it has only recently been possible to 

 outline any definite station program, the problems under study are 

 fundamentally similar) with especial emphasis on the life histories 

 and general ecology of individual species of comimercial importance. 

 This laboratory has been made the head-quarters for various of the 

 projects attacked on the periodic cruises. Thus the investigations 

 on the Physiology of the oyster have recently centered here, like- 

 wise those on the life history of the mackerel, on the distribution 

 and dispersal of fish eggs and larvae by ocean currents, on the 

 migrations of the cod fish, and on fish metabolism, to mention only 

 a f ew. -'■ 



-'•The Woods Hole Laboratory of the Bureau of Fisheries also ad.nits 

 outside investigators many of whose problems are not oceanograph ic. _
