Oyster shell is a crucial component of healthy oyster reefs. Shell planting has been a main component of oyster restoration efforts in many habitats and has been carried out on scales from individual and grassroots efforts to multiagency efforts across entire estuaries. However, the cycling and lifetime of the shell...
Salmon restoration has become a major priority in the Pacific Northwest. In the State of Oregon, much of
the responsibility for habitat restoration has fallen on local watershed councils, with the majority of their
funding coming from state and federal grants. Funding limitations, including the amount of funds allotted
to...
During two cruises in February and June of 2003, the erodibility of sediment along the western Adriatic Sea was measured using a "Gust erosion chamber". In addition, the surficial sediment properties were characterized through a suite physical and biological measurements including porosity, grain-size, inorganic carbon, organic carbon and colloidal carbohydrate....
The relationship between the outgoing long-wave radiation (OLR) field
over the tropical Pacific and wintertime monthly precipitation for the
western U. S. is investigated, using the mid-latitude upper-air circulation
as an intermediary. Principal components (PC's) of the 500mb monthly
averaged height field over the NE Pacific and western North America...
The marine climate of the Galapagos is spatially and seasonally
heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has
never been done. This study is an initial effort to establish the distribution and
community structure of zooplankton in the Archipelago. I collected zooplankton
samples by vertical tows over the Galapagos...
This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...
The objectives of this dissertation were to describe the complex oceanographic conditions around the Galápagos Archipelago (eastern equatorial Pacific), their seasonal variability, and their effects on patterns of cetacean occurrence. The physical and ecological factors leading to a plume of high phytoplankton biomass in the wake of the Galápagos were...
This internship was supported and funded by the Yap State Environmental Protection
Agency (EPA), the United States Department of the Interior, Office of Territorial and
International Affairs, and the University of Oregon Micronesia and South Pacific Technical
Assistance Program. What follows in this report is a description of the internship...
Tillamook Bay is the second largest estuary on the Oregon coast, and concerns have been raised whether human induced impacts have been responsible for the perceived increase in sedimentation rates during the past century. Major land-use practices within the five watersheds of the Bay include logging, forest fires, the construction...
