The quantification of microplastics along a primary Puget Sound river A study from headwaters to estuary
(2017-07)The world’s reliance on plastic is a contemporary dependence as its malleable function, low production cost, and increasing abundance has been universally favored over all other products. Created with the intention of ... -
A quantitative analysis of the carbon cycle and comparison of carbon remineralization rates in marine Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Sediment cores were collected and analyzed for rates of carbon remineralization. It was hypothesized that the sediments beneath regions and areas of relatively high primary production rates would exhibit higher carbon ... -
Radial growth of Balanophyllia elegans as a response to changes in carbonate system parameters DIC, pH, and CO32-
(2017-07)The steady, increasing flux of carbon dioxide from the atmosphere into the ocean is posing a major threat to the marine biota that depend on stable pH and chemical concentrations for biomineralization. One important and ... -
Recent changes to the biogeochemistry of Muchalat Inlet, B.C., and the implications for HABs
(2015-06)[author abstract] The western coast of Vancouver Island, B.C. experienced anomalous events in the late spring and early summer of 2014. A persistent warm sea surface temperature anomaly reached the fjords, as did a massive ... -
Reconstructing paleoceanographic oxygen conditions in the Soledad Basin, Mexico
(2012-06)[Author's Abstract] The global oceans contain relevant information about past environment. Oceanic sediments retain signatures from variations in productivity, water conditions and temperature making it possible to recreate ... -
Relating Tectonic Spreading Rate to Crustal Roughness across a Tectonic Triple Junction Using High-Resolution Multibeam Sonar
(2012-06)[Author's Abstract] Mid-ocean ridges, where magma is released to form new oceanic crust, can differ greatly in their shape depending on how quickly crust is produced and the complexity of the surrounding system of tectonic ... -
Relationship between Bottom Water Oxygen Concentration and Palmitic Acid Preservation in Saanich Inlet, BC and Hood Canal, WA
(2018-06-01)The global carbon cycle in the ocean is closely associated with dissolved oxygen in the surface ocean. Phytoplankton produce oxygen, and the oxygen in the atmosphere and surface seawater diffuses down to the seafloor. Dead ... -
The relationship between current flow direction and sediment distribution within slope-confined submarine canyons off the north coast of Moloka’i, HI
(2023-06)Submarine canyons play an important role in transporting sediments from terrestrial sources to abyssal environments. Sediment can be transported along continental shelves and into submarine canyons through bottom currents ... -
Relationship between phytoplankton abundance, available nitrate, ammonium, and temperature at Station ALOHA, and the R/V Roger Revelle Cruise RR1604.
(2022)The goal of the project was to assess the relationship between phytoplankton abundance, various available nutrient concentrations (𝑁𝑂3, 𝑁𝐻4) and temperature (C), based on data collected at station ALOHA, a time-series ... -
The relationship of tropical Pacific sea surface temperature and sea level to tropical cyclones on varying time scales
(2017-07)This study examined the relationship between sea surface height (SSH), sea surface temperature (SST), El Niño Southern Oscillation (ENSO), and tropical cyclones (TC) on high-frequency (monthly to yearly) and low-frequency ... -
Relationships of fine-grained glacial sediment and total organic carbon in Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)The relationship between marine geology and marine chemistry was explored in Glacier Bay by correlating sediment grain size to particulate organic carbon (POC.) Marine and alpine glaciers produce sediment in the bay. It ... -
Relative Abundance and Distribution of Phytoplankton in Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)This study measured and identified the diatom population at three distinct areas in Glacier Bay. Diatoms play a significant role in the absorption of carbon dioxide in the oceans, but have not been fully characterized in ... -
Resolving the Thickness of Submarine Lava Flows in the North Arch Volcanic Field Using Magnetometry
(2022)The North Arch Volcanic Field is a part of the greater Hawai’ian volcanic arch north of O’ahu. Only discovered in the 1960s; relatively little is known about it and the arch volcanism that formed it. One general property ... -
Roca Redonda Island formation due to development of an extensional transform zone, northern Galápagos Archipelago
(2006-03)The Galápagos hotspot is located only 250 km south of an east-trending mid-ocean ridge spreading center and transform fault. One theory holds that the northern islands of the Galápagos were not formed by hotspot volcanism. ... -
Satellite based productivity models across the Kuroshio extension
(2013-06)[author abstract] As anthropogenic perturbations to the Earth’s climate have continued to become more severe, it has become increasingly necessary to understand the processes that control atmospheric CO2. One such process ... -
Satellite Remote Sensing of Chlorophyll: Significance of PAR & Spatial Scale
(2012-06)[Author's abstract] Satellite remote sensing is used worldwide in many different sectors of science. The advent of remote sensing allows a global database of daily information. The National Aeronautics and Space Administration’s ... -
Scaling response of a canyon-incised shelf break
(2012-06)[Author's Abstract] The continental shelf break is a global, large-scale geologic structure which separates continents from the deep sea. Along the shelf break many finer-scale features can be recognized, such as canyons ... -
Seafloor terrain and sediment characterization at Molokaʻi, Lōʻihi, and Cross Seamount via seafloor mapping
(2011-03)Research conducted between 27 Dec. 2010–4 Jan 2011 in Hawaii, at Molokai, Loihi, and Cross Seamount, combined seafloor mapping with sediment analysis to provide a comparison of different sediments over different terrain ... -
Seasonal Patterns of Fin Whale Calls in the Northeast Pacific
(2021)After a century of commercial whaling fin whales are currently listed as a vulnerable species and are increasingly at risk of endangerment from new anthropogenic noise, vessel traffic, entanglement, and habitat degradation. ... -
Sediment accumulation rates in the West Arm of Glacier Bay, Alaska based on Lead-210 analysis
(School of Oceanography, University of Washington, 2008-06-19)The rate of sedimentation in Glacier Bay is considerably higher than in similar environments. Because of glacier melt, sedimentation rate is an important indicator of climate change. This study measured 210Pb in sediment ...
