Geochemical and petrogenetic effect of the interaction of the Southeast Indian Ridge and the Amsterdam-Saint Paul hotspot

Creator:: Priebe, Louise M. Douglas
Resource Type:: Masters Thesis
Full Text:: . Abstract David W. Graham The interaction of a migrating mid-ocean ridge and a near-ridge hotspot has a

Untangling the complexity of nearshore ecosystems : examining issues of scaling and variability in benthic communities

Creator:: Schoch, G. Carl
Abstract:: The objective of this research was to improve our understanding of how changes in the environment affect ecological processes. Change detection is often confounded by the large variation found in ecological data due to the difficulty of finding replicates in nature. Intertidal communities were chosen for studies of biophysical interactions...

Geochemistry and geochronology of ancient southeast Indian and southwest Pacific seafloor

Creator:: Pyle, D. G., Christie, David M., Mahoney, J. J., and Duncan, Robert A.
Abstract:: Within the Australian-Antarctic Discordance (AAD), a boundary exists between isotopically defined “Pacific-type” and “Indian-type” mid-ocean ridge basalt (MORB) erupted along the Southeast Indian Ridge (SEIR). This boundary has migrated westward beneath the easternmost AAD spreading segment at a minimum rate of 25 mm/yr since 4 Ma; however, its long-term history...

Calanoid copepod diet in an upwelling system : phagotrophic protists vs. phytoplankton

Creator:: Fessenden, Lynne M.
Abstract:: Calanoid copepod diet was investigated in Oregon coastal waters to determine the trophic significance of phagotrophic protists as copepod prey within an ecosystem where the microplankton biomass is typically dominated by large diatoms. Prior to and during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic ciliates were measured...

The Oregon placer mineral technical task force : Resources, management, and potential impacts

Creator:: Ross, Susan
Abstract:: In September 1988, the U.S. Secretary of the Interior and the Governor of Oregon announced the creation of the joint state-federal Placer Minerals Technical Task Force. The group was charged with performing an analysis of the potential economic and environmental aspects of placer mineral mining in the nearshore waters of...

Identification of layered cloud occurrences from the Lidar In-Space Technology Experiment and advanced very high resolution radiometer imagery

Creator:: Stevermer, Amy J.
Abstract:: Realistic assessment of the vertical distribution of clouds, particularly the occurrence of multi-layered systems, is critical for accurate calculations of radiative transfer in general circulation models. Such information is also useful in the design and improvement of satellite retrieval techniques. Current methods for retrieving cloud properties from satellite data assume...

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...

Diversity of bacterioplankton and plastid SSU rRNA genes from the eastern and western continental shelves of the United States

Creator:: Rappé, Michael Stephen
Abstract:: The phylogenetic diversity of two continental shelf picoplankton communities was examined by analyzing SSU (16S) ribosomal RNA (rRNA) genes amplified from environmental DNA with bacterial-specific primers and the polymerase chain reaction (PCR). Picoplankton populations collected from the pycnocline (10 m) over the eastern continental shelf of the United States near...
