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...

Defining habitat preferences of pelagic loggerhead sea turtles (Caretta caretta) in the North Atlantic through analysis of behavior and bycatch

Creator:: McCarthy, Abigail L.
Abstract:: For many species of marine turtle the characteristics that define pelagic habitat have yet to be fully identified. A better understanding of these habitat characteristics is critical to reduce high seas fisheries interactions with turtles, especially as the status of many turtle populations has placed them on the threatened or...

A cooperative effort to track Humboldt squid invasions in Oregon

Creator:: Chesney, Tanya A.
Abstract:: Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....

Video on the rocks : use of a video lander platform as a survey tool for a high-relief nearshore temperate rocky reef

Creator:: Easton, Ryan Reid
Abstract:: The nearshore waters off the Oregon coast (< 73 meters) are a region of high productivity and economic value, with a variety of habitats that include rock outcrops. Temperate reef habitats are important to many commercially important fishes inhabiting the Pacific coast, including canary rockfish (Sebastes pinniger) and yelloweye rockfish...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

Community-based sea turtle monitoring and management at Helen Reef, Hatohobei State, Republic of Palau

Creator:: Barr, Julie M.
Abstract:: Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...

Seasonal abundance and behavior of Steller sea lions in Oregon

Creator:: Katalinich, Jennifer D.
Abstract:: Behavioral studies of populations provide clues as to what influences their movements and life history strategies. This is an area of study that has been underutilized in research surrounding the declining western stock of Steller sea lions, Eumet opias jubatus, particularly with regards to haulout behaviors. During the time of...

Movement patterns and marine habitat associations of juvenile loggerhead sea turtles (Caretta caretta) in the southwestern Atlantic Ocean

Creator:: Barceló, Caren
Abstract:: Bycatch, or the incidental capture of non-target species, has been implicated as one of the main factors leading to population declines of many large marine vertebrates, including sea turtles. To effectively manage and conserve these long-lived species, their marine distribution, high use areas, foraging habitats, and regions of highest likelihood...

Physiological ecology of juvenile Chinook salmon (Oncorhynchus tshawytscha) rearing in fluctuating salinity environments

Creator:: Hackmann, Crystal R.
Abstract:: Estuaries provide juvenile salmonids with highly productive feeding grounds, refugia from tidal fluctuations and predators, and acclimation areas for smoltification. However, these dynamic, fluctuating salinity environments may also be physiologically stressful to growing juvenile fish. In order to evaluate the costs and benefits of estuarine marshes to juvenile Chinook salmon,...

Divergent anti-predator strategies and risk allocation in juveniles of three NorthPacific flatfishes

Creator:: Boersma, Kate S.
Abstract:: Frequent or lengthy predation risk can cause one of two modifications of prey feeding behavior: 1) postponement of feeding to less risky periods, or 2) resumption of feeding behavior despite persistent risk. North Pacific flatfishes exhibit both of these responses when confronted with temporal variation in risk, and this experimental...
