Inverse Modeling of the Deep Brazil Basin Circulation
(2021)The pathways of seawater through the deepest parts of the world ocean are relatively unknown but critical to understanding how the ocean distributes heat that is taken up at the surface. The deep and abyssal circulation ... -
Investigating changes in channel complexity across the coastal zone
(2012-06)[Author's abstract] Nearly half the world’s population lives in a coastal watershed where all the anthropogenic input to the hydrologic network are transported downstream and onto the continental shelf. This connectivity ... -
Investigating responses of calcium carbonate nucleation rates in artificial seawater to changes in saturation states due to ocean acidification
(2016-06)[author abstract] Reduced saturation states of carbonate ions caused by ocean acidification make it harder for marine calcifiers such as corals to build their shell or skeleton. Nucleation is vital to corals because it is ... -
Investigating the geological evolution of Rumble II West Volcano Using EM300 Bathymetry and TowCam Imagery
(2010-01-20)The geological evolution of Rumble II West was characterized by bathymetric mapping and undersea photography. The volcano was compared to the Brothers volcano, also in the Kermadec Arc. The pattern of faults in Rumble II ... -
An investigation into flow features at Cross Seamount, Hawaii
(2011-03)Seamounts are areas of raised bathymetry, which occur throughout the world’s oceans. They actively influence biological, chemical and geological processes in the ocean. This study examined the circulation pattern of the ... -
An investigation into sources and distributions of iron, aluminum, and nutrients in Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Iron in seawater is biologically significant for its contribution to primary productivity. This study showed a high livel of iron in Glacier Bay, as well as higher values for the metal in water beneath the mixed layer. ... -
Investigation of lava flow morphology using a sub-bottom profiler in the North Arch Volcanic Field
(2022)Located 100 km north of Oahu and over four kilometers of water, the North Arch Volcanic Field covers an area of 25,000 km2 and includes the longest known underwater lava flow. There have been a few previous studies of ... -
Investigation of the Equatorial Undercurrent on the eastern side of the Galapagos Islands
(2006-03)The Equatorial Undercurrent, or EUC, flows eastward throughout most of the Pacific Basin and acts as a conduit for water mass conservation in the equatorial region. The Galapagos Islands sit atop a platform located in ... -
Is the tidal triggering of earthquakes at Axial Seamount predictive of eruptions?
(2022)Scientists have long hypothesized that tidal forces can trigger earthquakes due to the change in stress along a fault. This phenomenon is called tidal triggering of earthquakes. My study investigated the tidal triggering ... -
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. ...
