Abstract

We surveyed eight of the permanent subtidal stations, and spent considerable time replacing surface and subsurface buoys on these stations. Little change was evident in densities of quantified invertebrates. Densities of some of the brown algae continued to increase. Surveys of random 30-m2 subtidal stations in the North Control were completed. Davidson current oceanographic period intertidal surveys were begun. High seas prevented us from occupying stations on several days of excellent minus tides; however, 12 random and 4 permanent stations were surveyed. The annual census of bull kelp, Nereocystis luetkeana, yielded a count of 11,323 surface canopy plants, a decrease from last year's estimate. Foam observations were continued in Diablo Cove. (15pp.)
