A systems approach to pelagic ecosystem dynamics in an estuarine environment

Creator:: Iverson, Richard L.
Abstract:: Phytoplankton dynamics in Auke Bay, Alaska, were studied during summer, 1969. Nitrate, chlorophyll a, particulate organic carbon, phytoplankton and zooplankton species composition and hydrographic and meteorological data were collected and analyzed. Nitrate input into Auke Bay through freshwater runoff was negligible. A bloom of Thalassiosira aestivalis formed the spring bloom...

Tidal exchange of decapod larvae and small benthic peracarids between the ocean and the Salmon River estuary, Oregon

Creator:: Gonzalez, Exequiel
Abstract:: Zooplankton samples taken during daylight periods in a fast flushing estuary on the Central Oregon coast were analyzed for Brachyuran and Anomuran larvae and also for benthic gammaridean amphipods and Myscidacea. Several larval stages of Pinnixa littoralis, Hemigrapsus oregonensis, Pachycheles spp., Cancer oregonensis and Pagurus granosimanus were sufficiently abundant for...

Early spring nutrient conditions of southeastern Alaska's Inside Passage

Creator:: Coughenower, D. Douglas
Abstract:: Observations were made of salinity, temperature, nitrate + nitrite, phosphate, silicate, total available nitrogen, and chlorophyll a in nine areas of the Alaskan Inside Passage during April of 1971. In general all properties indicated the water to be well mixed throughout this area. The conservative properties were particularly uniform. The...

Diversity and similarity of benthic fauna off Oregon

Creator:: Stander, Jeffrey M.
Abstract:: Samples of benthic organisms off the coast of Oregon, taken from depths varying from 50 to 2900 meters, have been analyzed in terms of diversity at a given station, and similarity and ecological distance to other stations. Estimates of epifauna abundance were also made. In the analysis an important distinction...

The distribution and partitioning of dissolved organic matter off the Oregon Coast : a first look

Creator:: Hill, Jon K.
Abstract:: The purpose of this thesis is to provide a first look at the spatial and temporal distributions of dissolved organic material (DOM) off the Oregon coast of North America. While this paper is not a comprehensive examination of these distributions, several patterns are identified as promising candidates for continued research....

Distribution of foraminifera, Netarts Bay, Oregon

Creator:: Hunger, Arthur Adelbert
Abstract:: Netarts Bay is a coastal lagoon on the northern Oregon coast. Four major sedimentary environments are recognized including channel, sand flats, mud flats, and marsh. Fine-grained sediment is carried in by streams and deposited in the marshes and mud flats. Fine sand for the channel and sand flats is derived...

Foraminiferal assemblages preserved in surface sediments correspond to multiple environmental and preservation variables

Creator:: Ross, Ann E. Morey
Abstract:: Here we investigate the relationships between modern foraminiferal assemblages from Atlantic and Pacific surface sediment samples and multiple environmental properties including water column and preservation variables using Canonical Correspondence Analysis (CCA). CCA finds two fauna] dimensions that are highly correlated to the environmental variables included in the analysis, and then...

The release of total and dissolved organic carbon from macroalgae and phytoplankton

Creator:: Kawasaki, Nobuyuki
Abstract:: Many phytoplankton and macroalgae release dissolved organic carbon (DOC). Many macroalgae also produce and store secondary metabolites which in some case have been shown to deter their grazers. The metabolites may be released into the surrounding seawater and could inhibit primary production. On the other hand, some phytoplankton can use...

Distribution, structure, and function of marine ecological communities in the northern California Current upwelling ecosystem

Creator:: Reese, Douglas Charles
Abstract:: Within systems characterized by substantial spatial and temporal variability, abundances of organisms tend to be higher in localized areas. Within the northern California Current system, the identification of such marine, biological hotspots would be of great importance to resource managers, conservationists, and research planners, and is consequently a growing area...
