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 ... -
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 ... -
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 ... -
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 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 ... -
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, ... -
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 ... -
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 ... -
Niche occupation of anammox bacteria in the eastern tropical North Pacific
(2012-06)[Author's abstract] Nitrogen is a limiting nutrient controlling oceanic primary production and important to the global carbon cycle. Consequently the nitrogen cycle is important to understanding how the oceans will react ... -
Nitrous Oxide in the eastern tropical North Pacific
(2012-06)[Author's abstract] Nitrous oxide (N2O) is an important greenhouse gas and is currently the most important ozone-depleting anthropogenic emission. However, its atmospheric budget is not well quantified, although it is well ...
