La Niña’s effect on the primary productivity of phytoplankton in the equatorial Pacific
(2011-03)This study examined whether La Nina had increased phytoplankton productivity in Hawaiian ocean waters. Dissolved oxygen was measured at four stations with inconclusive results. -
A Lagrangian study of the surface circulation of a fjordic system: the effects of preceding weather conditions and local geomorphology
(2010-05)Variation in the surface and near surface circulation patterns of Effingham Inlet, a fjord on the west coast of Vancouver Island, Canada, were measured using Lagrangian drifters over two days during the early spring of ... -
Landslide generated tsunamis: A smoking gun in Saratoga Passage, Puget Sound, Washington
(2008-07-01)The Puget Sound region with its high, steep bluffs is subject to landslides. An area of Puget Sound off Camano Island, near Onamac Point, was studied to determine if sediments there were a result of a landslide. The volume ... -
LiEFi (Light-Energy Fish): Using Simple Mechanical Models to Simulate Climatic Changes in Fish Communities
(2019)There are many different ways to model climatic changes: through computer modeling, idealized simulations, or real-life mechanical models. This project will use a simple fish-like ROV model with an idealized “fish-eye” ... -
Lignin compound composition of post-glacial sediments in Glacier Bay, Alaska
(School of Oceanography, Unversity of Washington, 2008-06-19)Sediments from Glacier Bay, Alaska, were analyzed to determine the vegetative source of lignin. These samples were analyzed for lignin compounds using a standard microwave digestion and gas chromatograph method. A mix of ... -
Limiting Nutrient Concentrations and Nutrient Assimilation and Storage Gene Expression across the Transition Zone Chlorophyll Front in the North Pacific Ocean
(2022)This study investigates limiting nutrient-relevant cyanobacterial gene expression across the Transition Zone Chlorophyll Front (TZCF) in the north Pacific Ocean. An increase in available nutrients due to upwelling in the ... -
Linking surficial geomorphology with vertical structure in high and low energy marine environments
(2016-06)[author abstract] Puget Sound is a complex system of high energy river inputs to lower energy large basins with direct connection to the open ocean through the Straits of Juan de Fuca. Using a high resolution bathymetric ... -
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 ...
