Heavy metal contamination in Puget Sound and Lake Washington sediments and benthic invertebrates; a focus on the influence of road material on extent of metal concentration
(2019)Heavy metallic elements are found naturally in nature, but have been released into soils, rivers, and bodies of water due to anthropogenic activity, increasing concentrations to levels potentially harmful to human and ... -
Heavy metal contamination in the greater Puget Sound from various anthropogenic point sources; concentrations in the sediment in comparison to marine biota
(2018-05-27)Heavy metals are naturally occurring elements that have a high atomic weight and are usually found in trace levels within the environment, but can become toxic to marine organisms at elevated concentrations. They can enter ... -
Heavy Metal Pollution in Puget Sound Marinas and Shipyards
(2019)As worldwide industrial activities continue to grow, concerns have risen over the varied and potentially harmful effects of heavy metal accumulation in the marine environment. While some of these elements may be necessary ... -
Historical sea level and accommodation zones along Baja California
(2012-06)[Author's Abstract] Change in sea level is an ongoing process which alters the coastal ecosystem on a continuous basis. The physical changes in the world’s coastal ecosystem due to sea level change have occurred many times ... -
How Edge Effects in Eelgrass Habitats Impact Organism Abundance and Diversity in the Puget Sound
(2019)Habitat transitions occur all over the globe. They can be seen in both terrestrial and marine environments and produce influential edge effects. In the Puget Sound, eelgrass habitats are commonly seen with abrupt habitat ... -
How The Environmental RNA Signature of Nitrate Reductase Can Be Used as a Predictor for Phytoplankton Distribution
(2021)With anthropogenic climate change altering the ocean, it is critical to understand what variables control phytoplankton distribution so we can predict how distributions will be altered as result of climate change. This ... -
Hydroaccoustic pinging as a diver tool for underwater navigation in surveying Puget Sound Eelgrass (Zostera marina) densities
(2016-06)[author abstract] Advances in technology have led to a change from data limited, direct observations to much numerous, more remote data. Despite this trend direct observations are still an important source of information ... -
Hydrographic study on the effect of Rumble III on the thermohaline structure and circulation
(2010-01-14)Isotherm (temperature), isohaline (salinity) and isopycnals (density) were plotted for the Rumble III volcano. The data were gathered through measuring current velocity, CTD in vertical transects, and the concentrations ... -
Hydrothermal vent fluid perturbations related to seismic activity at Axial Seamount, Juan de Fuca Ridge
(2021)Mid-ocean ridges are dynamic environments that transfer the largest amount of heat and chemicals from the Earth’s lithosphere to the hydrosphere. Continuous observations of the changes in mid-ocean ridge environments over ... -
Identifying a historic shoreline using fine-scale slope variation
(2013-06)[author abstract] A rise of just one meter of sea level rise could displace millions of people and cause billions of dollars of damage. This research identifies a historic submerged shoreline along the continental shelf ... -
Identifying and Monitoring Water Quality Needs for Puget Sound’s Aquaculture Industry and Environmental Security Through the Design and Use of a Prototype Sensor Suite
(2019)The impact of climate change on the environmental and economic security of marine resources has now entered the public and political discourse. The sectors of the marine industry that must make both short and long-term ... -
Impact of Databases on Oceanographic Citizen Science
(2019)Due to recent advances in low-cost and easily programmable micro-electronic sensors, citizen scientist interested in learning more about their personal connection to the ocean and those aspects of marine waters that they ... -
Impact of hypoxia on the vertical distribution of jellyfish in the Eastern Tropical Northern Pacific
(2012-06)[Author's Abstract] The vertical distribution of four taxa of jellyfish (Siphonophora, Thaliacea, Ctenophora and Hydromedusae) was sampled in Baja Bay, Mexico. The hypothesis that populations would be denser in the oxygen ... -
The Impact of the Mass Mortality of Ochre Stars (Pisaster ochraceus) and Sunflower Stars (Pycnopodia helianthoides) on Intertidal and Subtidal Communities in Puget Sound
(2017-07-24)Severe Sea Star Wasting Disease (SSWD) outbreaks were reported between Alaska and Baja California, including Puget Sound (Eisenlord et al 2016). Eisenlord et al 2016’s results from intertidal surveys in Tacoma and on the ... -
The impact of varying nutrient concentrations on the growth and size distributions of phytoplankton populations within the western equatorial Pacific
(2023-06)The purpose of this research is to identify how the surface water properties and population makeup of phytoplankton communities impact how their growth and size distributions respond to variations in nutrient concentrations. ... -
Impacts from aquaculture facilities on intertidal ecosystems using quadrant surveys and antibiotic tracers
(2013-06)[author abstract] Marine ecosystems are vulnerable to anthropogenic influences due to increased stresses from climate change and habitat destruction. Fish farming and other aquaculture practices have potential impacts on ... -
Impacts of pH on NSAID adsorption to microplastics in the North Pacific Gyre
(2022)The adsorption of non-steroidal anti-inflammatory drugs (NSAIDs) to microplastics, and subsequent ingestion by marine organisms, has many detrimental impacts on the marine organisms, including behavioral changes, reproduction ... -
In situ assessment of initial seafloor massive sulfide mining operation in Papua New Guinea using a cabled autonomous underwater vehicle system: a proposition
(2016-06)[author abstract] This project is a critical analysis of the impacts of the first effort to mine seafloor massive sulfide deposits (SMS). It will be linked to a proposal for assessment, and mitigation, of the negative ... -
