THE OPERATIONS OE THE LAUNCH ANTON DOHRN 

 IN SOUTHERN CALIFORNIA WATERS 



By Professor Albert B. Ulrey, A. M., 



Director of the Venice Marine Biological Station of the University of 

 Southern California 



'X^HE character of the work of the Marine Biological Station 

 ■*- of the L^niversity has been determined in large measure 

 by the operations of the station launch the Anton Dohrn. The 

 immediate field of her activities has been chiefly the region be- 

 tween Pt. Dume and Newport Bay and the Santa Catalina 

 Island region. The extreme limits of her sailings at this date 

 extend from the Coronado Islands on the southeast to Anacapa 

 Island on the northwest and out at sea to Sian Clemente Island. 



The launch has been used ( 1 ) in a biological survey of South- 

 ern California waters, (2) to procure living material for the ma- 

 rine station, (3) to provide supplies for special lines of research in 

 progress, (4) for investigation of special problems of economic 

 importance. 



The maps published herewith indicate the field of activities 

 in the biological survey. A series of thirty-five trips were made 

 from June to November, 1914, in the interest of the Li. S. Fish 

 Commission work relating to the Albacore problem. Each trip 

 made by the launch was directed ]3y a biologist who recorded 

 the data obtained and preserved representatives of most of the 

 animal and plant life found in the various localities. During the 

 five years' work the records kept aggregate a considerable vol- 

 ume of biological data and the specimens preserved represent 

 many of the species of the fauna and flora of Southern Cali- 

 fornia waters. 



It would have been impossible to accomplish without ample 

 funds the results attained except for the fact that we were able 

 to use the energy and enthusiastic devotion to a scientific goal 

 found in the students and instructors of the University. This 

 is particularly true with reference to operating" and caring for 

 the launch. No service was too severe or task too difficult for 

 these volunteer sailors to undertake. The fact that the launch 

 has sailed without mishap many times over the sea from Point 

 Dume to Newport and out at sea to Catalina and San Clemente 

 islands and has visited San Diego, Santa Rosa, Santa Cruz, and 

 Santa Barbara islands, speaks eloquently for the amateur sea- 

 manship of these men. 



The list of men to whom credit is due for service on the 

 launch is too long to publish here in full. The following have 

 given special time and service to the work. The responsibility 

 for carrying into execution the work of the Anton Dohrn has 

 been borne by Percy S. Barnhart and J. Ross Beck during the
