Table 3.— Total relative density and frequency of occurrence of the copepod species taken within 18 km 

 of the Oregon coast, during 1969, 1970, and 1971. Relative density is average number of individuals per 

 cubic meter in samples in which the species occurred. The table entries represent the sums of relative 

 density at each of four stations. A total of 33 samples were collected in 1969, 44 in 1970, and 40 in 1971. 



'The following species were found in less than five samples: Calanus plumchrus, Gaetanus immatures, 

 Paraeuchaeta japonica immatures, Candacia bipinnata, Eurytemora thompsoni, Rhincalanus nasutus, 

 Oncaea borealis, 0. tenella, O. media hymena, O. mediterranea, Sapphirina sp., and Microsetella sp. 



Table 4. -Total relative density and frequency of occurrence of other holoplanktonic taxa and 

 meroplankton taken within 18 km of the coast during 1969, 1970 and 1971 upwelling seasons. Entries are 

 sums of average abundances at each of four stations.
