NO. 1 HARTMAN, BARNARD: BENTHIC FAUNA OF DEEP BASINS 



ACKNOWLEDGEMENTS 



The University of Southern California and the Allan Hancock 

 Foundation provided the facilities of the VELERO IV and the labora- 

 tory space in which the studies were conducted. We are indebted to the 

 various crews that cooperated in taking and processing the samples on 

 board ship. To Captain Allan Hancock we are much indebted for con- 

 tinued interest and support. Dr. K. O. Emery and associates in the De- 

 partment of Geology provided the physical data, some of which are taken 

 from manuscript notes. Dr. Emery aided further in providing the chart 

 data and in organizing many of the trips to the deep basins. David Scholl 

 processed many of the samples aboard ship. Determinations of some 

 animal groups were made by others: Fred Ziesenhenne provided the 

 names of echinoderms ; Dr. Myra Keen aided with some of the mollusks ; 

 Dr. Orville Bandy supplied the name of a foraminif eran ; and Dr. John 

 Soule those of the bryozoans. 



HISTORICAL 



The deepwater fauna of southern California is known through 

 studies resulting from catches made during operations of the U. S. Fish- 

 eries Steamer ALBATROSS in 1904, when dredging and trawling were 

 done. Seven stations in four outer basins (Appendix I) yielded 24 species 

 of animals (Appendix V), of which 19 were various kinds of annelids, 3 

 were ascidians, one a sipunculid and another an amphipod. All were un- 

 known to science. Some of the same species have since been recovered 

 in quantitative samples from these or adjacent areas, and many other 

 kinds of animals have been found (Appendix VI). 



The San Pedro Basin has a limited and impoverished fauna (Hart- 

 man, 1955a) and shares these faunistic characteristics with Santa Monica 

 Basin (Hartman, 1956). 



The subsill pelagic waters support faunas which differ in the various 

 basins; they have been studied from photographs made aboard the 

 VELERO IV and are partly reported (Hartman and Emery, 1956).
