Assessment of N2 production in anoxic regions of Effingham Inlet, British Columbia
(2010-05)Anerobic processes that reduce fixed nitrogen to N2 gas were determined to be present in the anoxic regions of Effingham Inlet, British Columbia. Within this fjord two sills deter circulation of oxygen rich water from ... -
Assessment of nitrogen removal trends in the Eastern Tropical North Pacific using 15N labeling experiments
(2012-06)[Author's Abstract] Areas of low oxygen in the world’s oceans provide a suitable habitat for bacteria involved in the nitrogen removal process. The expansion of one such area in the Eastern Tropical North Pacific (ETNP) ... -
An Assessment of Noise Pollution Propagated by WSDOT Ferries in the Puget Sound
(2109)Increasing ferry traffic in the Puget Sound and Salish Sea raises concern for marine mammals due to noise pollution. This is not a topic of major environmental concern in the design process for future ferry generations. ... -
Assessment of wintertime carbon flux direction in the fjord system of Hood Canal in Washington
(2018-05-27)The relationship between carbon dioxide and the mechanisms behind its exchange between the ocean and atmosphere benefits the study and understanding of climate change given Carbon dioxide’s behavior as a greenhouse gas and ... -
Automatic recognition of seafloor features in sub-bottom profiles using eigenimages
(2015-06)[author abstract] Sonar is the primary tool used to remotely survey the seafloor. Sub-bottom profilers use pulses of sound to penetrate the seafloor and create an acoustic profile of the seafloor and sub- bottom. The ... -
Bacterial abundances and their relationship to iron around the Galápagos Islands, Ecuador
(2006-03)In an attempt to characterize the influence of an iron source on bacteria around the Galapagos Islands, bacteria were sampled at the surface and at four different depths from the R/V Thomas G. Thompson during 13-15 January ... -
Bacterial Biomass along the Kuroshio Extension
(2013-06)[author abstract] Bacteria are essential for the remineralization of nutrients in the ocean between different energy levels. Therefore, understanding what control bacterial abundance in the ocean is important. This ... -
Bacterial growth rates and bacterivory around the Galápagos Islands
(2006-03)The equatorial Pacific is an HNLC (high-nitrate, low chlorophyll) region, with the exception of the area around the Galápagos Islands, where there is commonly a relatively large standing stock of phytoplankton. In this ... -
Bacterioplankton community structure and enzymatic activity in Barkley Sound, Canada, and its response to a simulated diatom bloom
(2010-05)This study examined the bacterioplankton community dynamics in Barkley Sound, located on Vancouver Island Canada, and the extent to which the community structure would change with the occurrence of a simulated diatom bloom. ... -
Bathymetry of Eruptive Fissures in the Submarine North Arch Volcanic Field
(2022)Submarine volcanoes make up 75% of volcanic activity on Earth, but are relatively understudied due to the lack of real-time observations of eruptions and their inaccessibility, often several kilometers below sea level. ... -
Behavior analysis of oithona in hypoxic/anoxic conditions
(2016-06)[author abstract] Oithona, one of the most abundant and ecological important copepods found in the oceans, is considered to be the base of many food chains. Hypoxia- defined as dissolved oxygen levels below 2.0 mL- has ... -
Beryllium-7 sorption to inorganic particles in Tahsis Inlet, Nootka Sound, B.C.
(2015-06)[author abstract] Sediment deposition from fluvial inputs is one of the main ways new sediment is introduced into seabeds, but many other processes can occur before the sediment reaches the seafloor. Beryllium-7 (⁷Be) is ... -
“The Blob”: A Warm Anomaly’s Effect on Interannual Variability of Eastern Subtropical Mode Water
(2017-07-24)A high sea surface temperature (SST) anomaly occurred off the western coast of North America in the winters of 2013-2014 and 2014-2015, which scientists and journalist named the “Blob”. The region affected by this anomaly ... -
Bridging the gap in oceanographic data science curriculum: prototyping experiential learning materials in Python
(2019)The data-oriented field of oceanography asks professionals within it to be confident and capable in working with various types of oceanographic data. To develop such a skillset, individuals must have sufficient self-efficacy ... -
The carbon cycle of Glacier Bay, Alaska: primary productivity, the importance of terrestrial inputs and the air-sea carbon dioxide exchange
(School of Oceanography, University of Washington, 2008-06-19)The study examined dissolved organic carbon, alkalinity, particulate organic carbon, and wind speed over the period of a few days. Gas exchange between the atmosphere and ocean is eight times higher than over the open ... -
Carbon remineralization rates in marine sediments beneath areas of high and low primary productivity in the Galapagos Archipelago
(2006-03)This study was carried out in the Galapagos Islands in January 2006 to determine sedimentary carbon remineralization rates and compare them among regions of differing chlorophyll a concentrations and rates of primary ... -
Catastrophic volcanic activity at Rumble III volcano based on EM300 bathymetry and direct seafloor imaging
(2010-01-13)This study used multibeam sonar survey with a deep-towed camera system to produce the first detailed bathymetric maps of Rumble III. The first photographs of the Rumble III seafloor are also included in the paper. It is ... -
Changes in Acidification of the Water Column Across the California Coastal Upwelling Front
(2022-03-11)The waters off the coast of California experience upwelling that brings cold, nutrientrich, relatively acidic waters onto the continental shelf. During the wintertime, this upwelling system creates a front, and the pH ... -
Changes in bacterial concentrations with depth, temperature, and chlorophyll fluorescence in the Equatorial Pacific Ocean
(2023-06)It is important to consider the abundance of marine bacteria, as they play important roles in biogeochemical processes that are significant in the carbon cycle. Marine bacteria can give us insight about factors such as the ... -
Changes in water stratification due to methane plumes on the Washington Margin
(2018-05-27)The changing climate is causing more methane releases from the seafloor making it important to understand how methane plumes can impact the ocean. Methane plumes can have impacts on stratification and circulation which can ...
