Rapid equilibrium response of a marine diatom to external and internal nutrient concentrations

Creator:: Lundy, Daniel Wayne
Abstract:: Batch cultures of Skeletonema costatum were grown under continual light saturation, with nitrogen nutrients in limiting concentrations. Population parameters measured included ¹⁴C uptake, chlorophyll a, particulate carbon and nitrogen, and ammonia, nitrate, and nitrite, concentrations. A method was developed for measuring cellular nutrient reservoirs in laboratory cultures of marine phytoplankton....

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...

The distribution and role of "available" iron in two estuaries

Creator:: Holden, Robert Bennett
Abstract:: A detailed study of iron concentrations measured by the reducible, reactive ferrous, and extractable methods was conducted in Auke Bay, Alaska during June 1973 and in Hood Canal, Washington during October 1973 and April 1974. The concentrations by each method were generally highest at the bottom and decreased towards the...

An in-situ experiment on the effects of zooplankton grazing and nutrient regeneration on the phytoplankton of Yaquina Bay, Oregon

Creator:: Deason, Ellen Elizabeth
Abstract:: Natural populations of phytoplankton from Yaquina Bay, Oregon, were incubated in large polyethelene bags in- situ, with and without the natural assemblage of zooplankton. Samples were taken daily for two weeks in April, 1974. The biomass of phytoplankton in the bag without grazers reached values two to three times the...

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...

Studies on the occurrence, physiology, and ecology of bioluminescence in dinoflagellates

Creator:: Esaias, Wayne E.
Abstract:: To provide further information on the occurrence and geographical variations of bioluminescent capabilities of marine dinoflagellates, forty species, representing twelve genera, of dinoflagellates from Yaquina Bay, Oregon, were examined for bioluminescence as single cell isolates. Seventeen species from the genera Ceratium (1 sp.), Gonyaulax (3 sp.), and Peridinium (13 sp.)...

Physical hydrography and nutrient nitrogen budget of Auke Bay, Alaska

Creator:: Kirk, Deborah Kathleen
Abstract:: Physical sources of nutrient nitrogen for the Auke Bay, Alaska estuarine ecosystem were investigated. These sources included vertical dispersion, advection, and fresh water sources. Hydrographic circulation patterns for the bay, and a nutrient budget for the surface mixed layer were developed. Measurements of temperature, salinity, currents, wind velocity, rainfall and...
