Effects of ultraviolet-B radiation on marine phytoplankton

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...

Changing concentrations of CO, CH₄, C₅H₈, CH₃Br, CH₃I, and dimethyl sulfide during the Southern Ocean Iron Enrichment Experiments

Creator:: Wingenter, Oliver W., Haase, Karl B., Strutton, Peter, Friederich, Gernot, Meinardi, Simone, Blake, Donald R., and Rowland, F. Sherwood
Abstract:: Oceanic iron (Fe) fertilization experiments have advanced the understanding of how Fe regulates biological productivity and air–sea carbon dioxide (CO₂) exchange. However, little is known about the production and consumption of halocarbons and other gases as a result of Fe addition. Besides metabolizing inorganic carbon, marine microorganisms produce and consume...

Identifying habitat factors for canary rockfish (Sebastes pinniger) off Washington and Oregon using environmental data and trawl logbooks

Creator:: Vestfals, Cathleen D.
Abstract:: If fisheries managers are to effectively manage commercially exploited fish populations, a basic understanding of the factors that influence fish distribution and abundance is required. In 2005, efforts to identify Essential Fish Habitat (EFH) for the 82 groundfish species managed by the Pacific Fishery Management Council along the West Coast...

Determination of unsaturation-, growth phase-, and growth rate-dependent hydrogen isotopic fractionation in C₃₇ alkenones produced by Emiliania huxleyi

Creator:: Wolhowe, Matthew D.
Abstract:: Recent works have investigated use of the hydrogen isotopic composition of C₃₇ alkenones (δD[subscript K37s]), lipid biomarkers of certain haptophyte microalgae, as an independent paleosalinity proxy. I discuss herein the factors impeding such an application and identify the potential alternative use of δD[subscript K37s] measurements as a proxy for non-thermal,...

Modeling the energetics of Steller sea lions (Eumetopias jubatus) along the Oregon Coast

Creator:: Malavear, Maria Yolanda Garcia
Abstract:: A dynamic bioenergetic model for Steller sea lions (Eumetopias jubatus) was built using the STELLA simulation modeling system. The model is intended as an aid for the exploration of ecological questions regarding growth and survival of immature Steller sea lions (ages 1-3) living along the Oregon coast under different nutritional...

The cross-equatorial structure of tropical instability waves in sea surface height

Creator:: Lyman, John M.
Abstract:: A linearized model with two vertical modes has been developed to understand observed characteristics of monthly variability in the Equatorial Pacific from TOPEX/POSEIDON measurements of Sea Surface Height (SSH). The 2-mode model is obtained from an equatorial beta plane model that has been linearized about a geostrophically balanced mean flow...

Distribution and abundance of coastal fish and macro-invertebrates in the Galapagos Islands

Creator:: Figueroa, Diego
Abstract:: The Galapagos Islands, located off the coast of Ecuador, have a spatially diverse marine environment suitable for a variety of species with different climatic requirements. A year-long inventory program was carried out in 2000-2001 to provide baseline data on the abundances and distribution of coastal fish and macro-invertebrates. The purposes...

Studies on the spatial variability of phytoplankton physiology and biomass in the Oregon upwelling system

Creator:: Sanders, Rachel B.
Abstract:: The Oregon upwelling system is a region of high biomass and primary productivity as well as strong mesoscale variability. In order to examine the interaction of physical forcing and ecosystem dynamics, four 3-week sampling cruises were conducted in the Oregon upwelling system as part of the Northeast Pacific Global Ocean...

The sea state bias in altimeter estimates of sea level from collinear analysis of TOPEX data

Creator:: Chelton, Dudley B.
Abstract:: The wind speed and significant wave height (H1/3) dependencies of the sea state is in altimeter estimates of sea level, expressed in the form ∆hSSB=bH1/3, are examined from least squares analysis of 21 cycles of collinear TOPEX data. The bias coefficient b is found to increase in magnitude with increasing...
