Puget Sound Marine Station 



The Station is about a quarter of a mile from the town of Friday Harbor 

 on San Juan Island, and the Island lies between Bellingham and Victoria 

 in the northern portion of Puget Sound. This Island is one of a considerable 

 archipelago left by glacial erosion. The islands of the group are largely 

 composed of metamorphic rock and not easily eroded. The rocks are un- 

 usually clean from silt since there are no large streams on the islands. 

 Thus rock animals and plants find a congenial habitat. North of the Islands 

 is Georgia Strait, a body of water roughly 100x20 miles. This is mostly 

 drained and filled by tidal flows thru the channels among the San Juan 

 group of islands. Since the extreme tides are approximately 13 feet, strong 

 currents are caused, thus insuring an abundance of clean and well aerated 

 water. The temperature of the seawater is about 11.5° C. in July. This 

 seems to be a favorable temperature for many marine animals and plants. 

 The marine life is therefore quite numerous in species, and particularly 

 abundant in individuals. 



The Station is open during the last week in June and the whole of July; 

 6 weeks. Research rooms are available at $50 for the season. Tents are 

 for rent by the Station, and a mess is conducted by it. Both the tents and 

 mess are conducted at a rate merely to be self-supporting over a period of 

 years. The fee without research room is $10 for the season. Class work 

 is given in marine zoology and botany. 



The Station is financially supported by the University of Washington, 

 with the cooperation of the following: 

 Whitman College. 

 University of Oregon. 

 University of Kansas.
