Mounting concern about the potential effects of minor oil spills in the Puget Sound region led to the design and implementation of experiments whose purpose was to determine the effects of crude oil spills on selected members of hard substrate, subtidal marine communities. By oiling an early colonizing species of replicate substrates, we simulated the effects of a one-time oiling event on an initial hard substrate colonizer, the encrusting bryozoan Parasmittina trispinosa. Subsequent community development was then monitored over a period of several months.Experimental manipulations were conducted in the laboratory on panels which prior to and after manipulation events were positioned in the natural environment. Thus panels were subjected to natural events except for those we experimentally controlled . These experimental methods on artificial surfaces were determined to be feasible for further experimental substrates of this type. 1982 NOS (National Ocean Service) Library Public Domain 1935
