210Pb Accumulation Rates in Andvord Bay, Western Antarctic Peninsula
(2017-07)With the rate of temperature rise on the Western Antarctic Peninsula (WAP) being six times higher than the global average, the effects of modern climate change on glacier dynamics and meltwater production hold particular ... -
Abundance and distribution of bacteria and viruses in the various ecotypes of the Hawaiian Islands Florence
(2011-03)Viruses and bacteria are highly abundant in the marine realm. Many studies have shown that viruses often exceed bacteria in abundance by an order of magnitude. This study utilized epi-fluorescence microscopy and DAPI and ... -
The Abundance and Distribution of Small Zooplankton near Cross Seamount
(2011-03)Seamounts are isolated shallow regions of the oceans formed by volcanoes. Seamounts have been found to support unusually large numbers of fish. It is possible that fish on seamounts are feed on small animals called ... -
The abundance, distribution, and diversity of ichthyoplankton in the Puget Sound estuary and San Juan Islands during early spring
(2007-05)This study examined the diversity of fish species using Puget Sound as a nursery. Five locations in Puget Sound were sampled, and the resulting ichthyoplankton were identified. The significance of the findings for the value ... -
Accuracy assessment of depth estimates from variation in pre- and post-processing of multi-beam SONAR surveys in a fjord environment
(2015-06)[author abstract] The demand for accurate, high resolution bathymetric maps has risen with increases in utilization of offshore resources. This demand has been met with advances in technology. However, surveyors must ... -
Adult female Pseudocalanus abundance, size, and egg production during the winter in Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Pseudocalanus sp. were measured in Glacier Bay before the spring phytoplankton bloom. Low chlorophyll was present, as well as low numbers of the zooplankton. Pseudocalanus sp. were widely distributed throughout Glacier Bay. -
Air-sea CO2 exchange in the Kuroshio and its importance to the global CO2 uptake
(2013-06)[author abstract] The Kuroshio Extension in the western North Pacific is a very significant region in the global CO2 flux estimates. Measurements of surface concentrations of CO2 during a 22-day cruise off the coast of ... -
Alexandrium cyst abundance in Nootka Sound aquaculture and towns
(2016-06)[author abstract] This study measures the number of Alexandrium cysts from samples collected near fish farms found in Nootka Sound in December of 2015. This measurement can indicate the health of the marine environment and ... -
Alkalinity Increase in the Arabian Gulf
(2019)Ocean acidification is an issue that is becoming of increasing global concern due to the dramatic impact it has on marine life wellness as well as economy. The Arabian Gulf uses pearl oysters and coral reefs as a major ... -
The ambient soundscape of inland waters in Seattle, Washington: bridge traffic as a source of urban underwater noise pollution?
(2016-06)[author abstract] Increasing human population is adding anthropogenic sources of noise to natural ambient sound levels and threatening marine ecosystem function and viability. Overwater bridges, features of the Seattle ... -
Analysis of Dinoflagellate Species Distribution in the Puget Sound and their Environmental Conditions from 2015-2022
(2022)Marine dinoflagellates live in conditions that if changed, can create dangerous environments promoting harmful algae blooms (HABs). This study investigates the drivers of species distribution and bloom peaks using data ... -
Analysis of Nitrite Concentrations Over Time in the Eastern Tropical North Pacific
(2017-07)The Oxygen Minimum Zone in the Eastern Tropical North Pacific is the largest and most intense in the world. The lack of oxygen causes bacteria to respire anaerobically and therefore changes the nitrogen cycle. Nitrite has ... -
Analysis of subsurface currents in the West Arm of Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)An Acoustic Doppler Current Profiler (ADCP) was used to measure the tides and currents of Glacier Bay. Data points were limited both temporally and spatially, but a general image of the currents at three depth ranges was ... -
Analysis of zooplankton species composition and depth-based habitat preference in Nootka Sound, B.C., Canada
(2015-06)[author abstract] The composition and abundances of zooplankton were studied in Nootka Sound, an estuarine fjord in British Columbia, Canada in winter 2014. Net tows were conducted at ten stations with varying water column ... -
Analyzing drifter designs and data gathering methods in complex estuarine environments
(2015-06)[author abstract] The ability to accurately and consistently map ocean circulation is important for understanding marine processes like sediment transport, pollution distribution, and plankton migration. My study compares ... -
Annual Carbon Export at the North Pacific Axial Seamount
(2019)As anthropogenic CO2 levels rise, it becomes increasingly important to quantify the flux from the surface ocean down into the deep, where it may be sequestered for thousands of years. The goal of this project is to estimate ... -
Anthropogenic CO2 accumulation in the North Pacific Ocean from changes in C/12C of dissolved inorganic carbon
(2009-02-23)Carbon stable isotope data in the Northeast Pacific Ocean was used to track the uptake of anthropogenic carbon dioxide. There are suggestions that the Northeast Pacific has weakened as a sink for anthropogenic carbon ... -
Are fjords sources or sinks of CO2? A study of air-sea CO2 fluxes in Nootka Sound, B.C.
(2015-06)[author abstract] Carbon dioxide, an important atmospheric greenhouse gas, has increased approximately 40% in the past 200 years due to anthropogenic activity. As a result of this, the global carbon cycle has been thrown ... -
Assessing euphausiid homogeneity in Puget Sound scattering layers
(2019)Euphausiids are ecologically important zooplankton in Puget Sound that vertically migrate and can form scattering layers. The depth of euphausiids across sex, species, and length affects what predator-prey interactions ... -
Assessing the Influence of Acoustic Variation on the Acquisition of Bathymetric Surveying Data
(2013-06)[author abstract] The field of hydrographic surveying is inherently important to achieving a true understanding of the world that underlies the vast bodies of water that cover the earth. In this study I will determine the ...
