Twenty-three bottom-trawl fish assemblages were identified from the relative biomass of
33 dominant species that occurred in the National Marine Fisheries Services' triennial
trawl surveys over the continental shelf and upper slope off California, Oregon, and
Washington from 1977 to 1992. The assemblages accounted for about 70% of the total...
Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies of Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...
Manganese nodules are concretions which are widely distributed on
the bottom of marine waters as well as on the bottom of some lakes.
They vary in size, abundance, and to some extent composition, with
location. The nodules are of potential economic value because of the
nickel, copper, cobalt and manganese...
California, Oregon and Washington, in cooperation with the National Marine Fisheries Service and the Pacific Marine Fisheries Commission, have initiated a coastwide Dungeness Crab Management Program. The primary objective of the program is to develop economic and biological information essential in supporting management decisions leading toward better management of the...
This ethnography describes RV [recreational vehicle] seasonal migration as an adaptive, transhumant strategy. The study population is retired, transhumant migrants, who are members of a nation-wide, membership camping organization. Fieldwork was conducted over a period of seven months at two sites located on the West Coast. These sites reflect northern...
In 1973, Oregon, Washington and California along with the National Marine Fisheries Service and the Pacific Marine Fisheries Commission "entered into a cooperative State/Federal Dungeness Crab Management Program." As part of the process of setting up a coastwide management program, this 1977 report is intended to "inventory and evaluate the...
