A Low-Volume Flow-Through System for Rearing Pacific Oyster (Crassostrea gigas) Larvae

Creator:: Fleener, Henry R.
Abstract:: Standard larval Pacific oyster (Crassostrea gigas) rearing systems can be described as either static or continuous flow. While rearing oyster larvae in static cultures can be a low-cost and simple method, static systems require significant husbandry effort, floorspace and can produce highly variable results due to environmental variance among cultures....

The Genetics of Larval Fitness in the Pacific Oyster: Responses to Acidified Seawater and Temporally Dynamic Selection Processes

Creator:: Durland, Evan R.
Abstract:: The Pacific Oyster (Crassostrea gigas) is one of the most economically and ecologically significant shellfish species worldwide. In the Pacific Northwest United States (PNW), the sustainability oyster stocks is increasingly threatened by ocean acidification (OA), which has had significant negative effects on the aquaculture industry in this region over the...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

An introduced Asian parasite threatens northeastern Pacific estuarine ecosystems

Creator:: Chapman, John W., Dumbauld, Brett R., Itani, Gyo, and Markham, John C.
Abstract:: The introduced Asian parasitic bopyrid isopod, Orthione griffenis, was first discovered on the Pacific coast of North America in Washington in 1988 and next in California in 1992. The range of Orthione presently extends from British Columbia to Baja California, where it infests at least two species of the native...

Hydroacoustic monitoring of oceanic spreading centers: Past, present, and future

Creator:: Dziak, Robert P., Bohnenstiehl, Delwayne R., and Smith, Deborah K.
Abstract:: Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means available to observe seafloor-spreading events in real time is via the remote detection of the seismicity...

Larval development in the Pacific oyster and the impacts of ocean acidification : differential genetic effects in wild and domesticated stocks

Creator:: Durland, Evan, Pierre De Wit,, Meyer, Eli, and Langdon, Chris
Abstract:: The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....

Capture-Related Stressors Impair Immune System Function in Sablefish

Creator:: Lupes, Sarah C., Davis, Michael W., Olla, Bori L., and Schreck, Carl B.
Abstract:: The sablefish Anoplopoma fimbria is a valuable North Pacific Ocean species that, when not targeted in various commercial fisheries, is often a part of discarded bycatch. Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the...

Post-Breeding Season Migrations of a Top Predator, the Harbor Seal (Phoca vitulina richardii), from a Marine Protected Area in Alaska

Creator:: Womble, Jamie N. and Gende, Scott M.
Abstract:: Marine protected areas (MPAs) are increasingly being used as a conservation tool for highly mobile marine vertebrates and the focus is typically on protecting breeding areas where individuals are aggregated seasonally. Yet movements during the non-breeding season can overlap with threats that may be equally as important to population dynamics....

Applications of slow-moving autonomous platforms for passive acoustic monitoring and density estimation of marine mammals

Creator:: Fregosi, Selene
Abstract:: Advances in mobile autonomous vehicles for oceanographic sensing provide new opportunities for passive acoustic monitoring of marine mammals. Acoustically equipped mobile autonomous platforms, including gliders, deep-water profiling floats, and drifting surface buoys can survey for a variety of marine mammal species over intermediate spatiotemporal scales. Additionally, such mobile platforms may...
