Man in the marine environment

Creator:: Hogg, Thomas C., Smith, Courtland L., and Davis, Wilbur A.
Abstract:: This report has three primary objectives; it attempts to examine the relationship of various cultural systems to the marine environment, seeks to create an inventory of uses man has put the marine environment to, and makes an analysis of the attitudes of people towards the marine environment.

Bayesian hierarchical modeling of Pacific geoduck growth increment data and climate indices

Creator:: Helser, Thomas E., Lai, Han-lin, and Black, Bryan A.
Abstract:: Growth increment widths from hard structures of marine and freshwater fish and bivalve species are increasingly used to model growth and elucidate relationships with environmental variability. Fully characterizing the intrinsic age-related growth variation among individuals within and between populations, while estimating the extrinsic environmental effects simultaneously, can be challenging. Using...

Thermal reaction norms for growth vary among cohorts of Pacific cod (Gadus macrocephalus)

Creator:: Hurst, Thomas P., Munch, Stephan B., and Lavelle, Kate A.
Abstract:: While much effort has been directed at determining the spatial scales of adaptation in thermal reaction norms for growth, it is widely assumed that these reaction norms have high temporal stability. Water temperatures in the Gulf of Alaska in 2007 were the coldest on record since the mid-1970s and we...

Cold front induced changes on the Florida panhandle shelf during October 2008

Creator:: Kamykowski, D., Morrison, J. M., McCulloch, A. A., Nyadjro, E. S., Thomas, C. A., Sinclair, G. A., and Grabowski Pridgen, K.
Abstract:: A significant step transition between seasonally stratified and destratified hydrographic conditions occurred during an October 2008 cruise to the Florida Panhandle Shelf along a cross-shelf transect that was sampled before and after a cold front passed through the area. Meteorological measurements from nearby ocean and land-based stations characterized the event....

Diel Feeding Chronology, Gastric Evacuation, and Daily Food Consumption of Juvenile Chinook Salmon in Oregon Coastal Waters

Creator:: Benkwitt, Cassandra E., Brodeur, Richard D., Hurst, Thomas P., and Daly, Elizabeth A.
Abstract:: The diel feeding periodicity of juvenile Chinook salmon Oncorhynchus tshawytscha was determined from stomachs collected in coastal waters off Oregon in 2000 and 2003. Juvenile Chinook salmon exhibited a diurnal feeding pattern with morning and evening feeding periods. There were differences in the duration and magnitude of the dawn and...

Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish

Creator:: Ruzicka, James J., Brodeur, Richard D., Emmett, Robert L., Steele, John H., Zamon, Jeannette E., Morgan, Cheryl A., Thomas, Andrew C., and Wainwright, Thomas C.
Abstract:: The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering...

Estimating minke whale (Balaenoptera acutorostrata) boing sound density using passive acoustic sensors

Creator:: Martin, Stephen W., Marques, Tiago A., Thomas, Len, Morrissey, Ronald P., DiMarzio, Nancy, Moretti, David, Mellinger, David K., and Jarvis, Susan
Abstract:: Density estimation for marine mammal species is performed primarily using visual distance sampling or capture-recapture. Minke whales in Hawaiian waters are very difficult to sight; however, they produce a distinctive “boing” call, making them ideal candidates for passive acoustic density estimation. We used an array of 14 bottom-mounted hydrophones, distributed...

Estimating animal population density using passive acoustics

Creator:: Marques, Tiago A., Thomas, Len, Martin, Stephen W., Mellinger, David K., Ward, Jessica A., Moretti, David J., Harris, Danielle, and Tyack, Peter L.
Abstract:: conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from transect lines or some form of capture-recapture on marked or uniquely identifiable individuals. However, many species are difficult to sight, and cannot be easily marked or recaptured. Some of these species produce...

Tracking North Pacific Humpback Whales To Unravel Their Basin-Wide Movements

Creator:: Palacios, Daniel M., Mate, Bruce R., Baker, C. Scott, Hayslip, Craig E., Follett, Thomas M., Steel, Debbie, Lagerquist, Barbara A., Irvine, Ladd M., and Winsor, Martha H.
Abstract:: In 2014, Oregon State University (OSU) initiated a multi-year project to study humpback whale (Megaptera novaeangliae) migrations in the North Pacific Ocean using satellite tracking technology in combination with genetic and photo-identification (photo-ID) analyses. The study is highly relevant to management, given the need for new information arising from the...

Spatially explicit capture–recapture methods to estimate minke whale density from data collected at bottom-mounted hydrophones

Creator:: Marques, Tiago A., Thomas, Len, Martin, Stephen W., Mellinger, David K., Jarvis, Susan, Morrissey, Ronald P., Ciminello, Carroll-Anne, and DiMarzio, Nancy
Abstract:: Estimation of cetacean abundance or density using visual methods can be cost-ineffective under many scenarios. Methods based on acoustic data have recently been proposed as an alternative, and could potentially be more effective for visually elusive species that produce loud sounds. Motivated by a dataset of minke whale (Balaenoptera acutorostrata)...
