Macro and micro plastics in an urbanized and non-urbanized fjord estuary in the Northeast Pacific Ocean
(2016-06)[author abstract] Plastics, synthetic polymers which are durable and long lasting, have been appearing as marine debris for many decades. Macro-plastics (larger than 5 mm) and their effects on marine life have been well ... -
Macrofaunal communities and their relationship with microbial mats: a comparison between the Northwest Caldera site and Cone site of Brothers Volcano, Kermadec
(2018-05-27)Hydrothermal vent systems and their emissions of mineral-rich fluids provide deep-sea oases for the development and long-term existence of chemosynthetic microbial communities as well as macrofaunal communities. The ... -
Manganese concentration of hydrothermal plume at Pele’s Pit, Loihi Seamount, Hawaii
(2011-03)Manganese (Mn) in hydrothermal vent plumes is an indicator of the vent characteristics that spawned the plume. Mn concentrations in Pele's Pit in Hawaii and the Cleft segment in the Juan de Fuca Ridge were compared. Mn was ... -
Mapping Whidbey Island and Possession Sound landslide susceptibility using an additive linear model
(2016-06)[author abstract] The Puget Sound region has a multitude of natural disasters dating back over thousands of years. Due to extreme weather conditions and seismic activity landslides have been a frequently occurring disaster. ... -
Marine Bacteria Colonization Rates on Microplastics in the North Pacific Subtropical Gyre
(2022)Plastic pollution is a growing concern in the microecology of the oceans. Studying bacteria colonization rates on plastic provides one way of understanding of how toxic debris can move through the food chain through ... -
Marine Bacterial Growth Rates in the Presence of Microplastics
(2022)This study investigated the effects of microplastics (MPs) on the growth of marine bacteria in the open ocean to try to obtain a general picture on whether or not bacteria can be harmed by or benefit from the presence ... -
Marine Debris: Modeling the Spatial Distribution of Sinking Plastics into the Deep Ocean
(2017-08)Four to twelve million metric tons of plastic enter the ocean each year. Although there is such a large influx of plastic entering the ocean, much of it does not remain floating at the surface. I implemented a wind-driven ... -
Measurement of pH: comparing methods across the Kuroshio Extension
(2013-06)[author abstract] Accurate pH measurements are the foundation for assessing the extent of ocean acidification, and provide the motivation for this study. We present pH values along a cruise track that crosses the Kuroshio ... -
Measuring physical characteristics and properties of Loihi seamount
(2011-03)The Loihi seamount is an active underwater volcano that has several known venting sites including Pele's Pit. CTD data were gathered and analyzed to characterize the recent volcanic activity of Pele's Pit. It was determined ... -
Measuring the abundance and distribution of microplastics and marine organisms across the surface of the equatorial Pacific using a Manta Net
(2023-06)The increasing production of plastics and their long lifespan have led to concerns about the accumulation of microplastics in marine environments. Due to their ability to be mistaken for food, microplastics act as a ... -
A mechanical design approach to testing fluid turbulence over a rough surface
(2013-06)[author abstract] This experiment took a mechanical design approach to analyzing aquatic energy loss through observing small scale water movement across a rough surface. The project was conducted in three phases. The ... -
Meridional mixing of water masses in the Kuroshio Extension: Origins of North Pacific Intermediate Water anomalies
(2013-06)[author abstract] Freshwater layers were discovered at intermediate depths north of the Kuroshio Extension front in February 2013. The anomalous layers of freshwater were determined to have originated in the Sea of Okhotsk, ... -
Microbial Comparison of Anoxic Saanich Inlet and Oxic Hood Canal using 16S Community Analysis
(2018-05-27)Microbes play a critical role in the marine environment. They cycle nutrients, fix carbon, and can severely alter the water chemistry. Around the world, a place that they are especially important is in marine oxygen minimum ... -
Microplastic abundance throughout Puget Sound
(2018-05-27)Microplastic pollution in the ocean is caused by the human population, and the way it transports throughout the water can be affected by numerous factors such as wind, tides, and residence times of the water. Microplastic ... -
Model/data comparison of a sewage outfall in Puget Sound using ammonium as a tracer
(2007-05)Modeling the effluent plume from the Renton Treatment Plant in addition to monitoring ammonium levels is one way to monitor the water quality of Puget Sound. The modeling was made possible using a Visual Plume (VP) computer ... -
Monitoring Benthic Conditions as an Early Warning System for Alexandrium Blooms in Puget Sound
(2017-07-24)The production of saxitoxin by the dinoflagellate Alexandrium catenella and the bioaccumulation of neurotoxin in shellfish can result in people contracting paralytic shellfish poisoning (PSP) after consuming contaminated ... -
Mysterious mounds of southern Hood Canal:dumpsites,landslide deposits or glacial debris
(2007-05)In 2005 two large seafloor mounds 30-40m high and approximately 350m in diameter were partially imaged in Southern Hood Canal.The geophysical and sediment data indicate that the mounds are at least 12,000 years old and ... -
N* variation within the Eastern Tropical North Pacific
(2012-06)[Author's Abstract] N* is a summary parameter used to describe areas of the ocean as either sources or sinks of fixed nitrogen, with positive values denoting nitrogen fixation (a source) and negative values signaling ... -
Natural and Anthropogenic Changes to the Dissolved Inorganic Carbon System in the Western Equatorial Pacific During the Last Three Decades
(2023-06)The Western Pacific is a relatively unstudied area that is important for the climate because it is influenced not only by natural processes such as El Niño Southern Oscillation (ENSO) and seasonal variability but also the ... -
Near-shore wave power characterized with a remotely controlled surface vehicle in Admiralty Inlet, Puget Sound, WA
(206-06)[author abstract] Wave power availability in Admiralty Inlet, Puget Sound, WA (USA) was assessed using measurements from a surface wave characterization vehicle. The device was designed to analyze wind and wave power, with ...
