“This report summarizes project progress in FY 1976 on the first phase of a survey on the continental shelf and upper continental slope off the coast of Washington. The second and final phase is a replicate survey scheduled for FY 1977. Objectives of the survey were to obtain estimates of...
Groundfish surveys off the Washington coast were conducted in September of 1975 and 1976 between Cape Flattery and the Columbia River. The primary purposes of the surveys were to obtain estimates of biomass and further our knowledge on population parameters of important groundfish species, especially flatfish, occupying the continental shelf...
This report summarizes program progress in FY 1973. Activities were directed entirely at completing the second phase of the work started in 1971, i.e., to complete the resource survey of the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...
This report summarizes program progress in FY 1974. Activities were directed entirely at completing the third of four phases of work started in 1971. The survey conducted in September 1973 was the second run over the continental shelf off the northern Oregon coast. Objectives of the survey were to obtain...
This report summarizes project progress in FY 1974. Activities were directed entirely at completing the fourth and final phase of work started in 1971, i.e., to survey groundfish resources on the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...
This report summarizes program progress in FY 1972. Activities were directed almost entirely toward the groundfish survey of the continental shelf off Oregon between the Columbia River and Cape Blanco. Since the area was too large to be surveyed in one cruise, it will be surveyed over a two year...
Groundfish surveys off Oregon were conducted over a four year period (1971-74)
between the Columbia River and Cape Blanco. Primary purpose of the surveys was to obtain estimates of biomass of important groundfish occupying the continental shelf and upper continental slope.
Survey design was based on a 5 x 5...
Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...
Although nearshore macroinvertebrates are integral members of high
mountain lentic systems, knowledge of ecological factors influencing their
distributions is limited. Factors affecting distributions of nearshore
macroinvertebrates were investigated, including microhabitat use and
vertebrate predation, in the oligotrophic lakes of North Cascades National
Park Service Complex, Washington, USA, and the conformity...
