Eddy impact on anthropogenic chemicals in the lee of Hawai’i
(2011-03)Eddies are a common feature in the ocean waters off Hawaii. This study analyzed the natural and anthropogenic chemicals found in the lee of Hawaii. -
Efects of changing salinity on the lipid composition of Salinivibrio costicola and potential applications as a salinity indicator
(School of Oceanography, University of Washington, 2008-06-19)Salinivibrio costicola is demonstrated to potentially work as a proxy for salinity. Salinity increases in lakes during dry periods, so finding an organism in which salinity changes can be tracked will help track climate ... -
Effect of Acartia grazing on the size distribution of phytoplankton in Academy Bay, Galapagos
(2006-03)The goal of this experiment was to determine if Acartia, a species of zooplankton, fed based on the size of food available. Acartia which more specifically are a type of copepod, have demonstrated this in other experiments. ... -
Effect of cross channel salinity imbalance due to freshwater influence in a narrow estuary
(2015-06)[author abstract] Nootka Sound is a group of narrow and deep fjord-like inlets on the west coast of Vancouver Island. This understudied estuarine system was the focus of an 11 December to 21 December 2014 University of ... -
The effect of frontal features on chlorophyll concentration within the Kuroshio
(2013-06)[author abstract] Physical features in the ocean created by winds and currents affect the productivity of the surrounding area. Frontal disturbances and upwelling eddies that draw nutrients up from deep water sustain ... -
Effect of glacial retreat on sub-surface sediment accumulation in Glacier Bay, Alaska: evidence from 3.5 kHz records
(School of Oceanography, University of Washington, 2008-06-19)The sediments in three areas of Glacier Bay were analyzed using data obtained through echo sounding. Tarr Inlet, the closest to the Grand Pacific Glacier, showed rounded hummocky structures and less fine-grained sediment. ... -
The effect of lower pH on phytoplankton growth in the Galapagos Archipelago
(2006-03)Average ocean pH has dropped 0.1 units over the last 100 years to its current level of 8.1. Models suggest that ocean pH could further drop by up to 0.7 units within the next 300 years. This research focused on the effect ... -
The effect of predatory chaetognaths on zooplankton assemblages at the start of the spring bloom in Glacier Bay, Alaska, U.S.A.
(School of Oceanography, University of Washington, 2008-06-19)Galcier Bay is a suitable ecosystem for chaetognaths with their main prey being the relatively abundant Calanus copepods. Evidence supports a separate nursery habitat for juvenile chaetognaths. A significant negative ... -
The effect of shore armoring on beach slope in mixed sand-and-gravel beaches
(2013-06)[author abstract] This study is a comparison of beach orientation, fetch length, and seawall toe height for 31 pairs of armored/unarmored, mixed sand-and-gravel beaches in southern Puget Sound. Beach profiles from top ... -
Effectiveness of flipped vs traditional course structures in upper division oceanography courses
(2021)In the past decades the introduction of online and remote learning has created the need for new ways to teach content that focus on the active learning component of teaching, one of these methods is the flipped course ... -
Effects of Earthquakes on Hydrothermal Vent Temperature and Resistivity at the Main Endeavor Field, Northeast Pacific
(2021)Hydrothermal vents are important deep ocean structures that provides a necessary biogeochemical environment which supports life. The flux of high temperature vent fluid, via hydrothermal circulation, mixes with cooler ocean ... -
Effects of fluvial and marine processes on nearshore suspended sediment concentrations off the Elwha River
(2013-06)[author abstract] The goal of this project was to determine whether river or marine processes had a stronger effect on the suspended-sediment content (SSC) of water off the mouth of the Elwha River. This was done in ... -
The Effects of Glacial Melting on Precipitation Patterns in Jellyfish Lake, Palau Derived from Hydrogen Isotopes in Algal Lipids
(2021)A meltwater-induced disruption of the Atlantic Meridional Overturning Circulation (AMOC) 8.5- 8 kyr impacted climate globally, with evidence from around the continental Pacific suggesting large perturbations to rainfall ... -
THE EFFECTS OF IRON SUPPLEMENTATION ON PRIMARY PRODUCERS IN THE WESTERN EQUATORIAL PACIFIC OCEAN
(2023-06)This study investigates the effect of iron (FeCl3) incubation on phytoplankton growth in the western Equatorial Pacific, an area known for its high-nutrient, low-chlorophyll (HNLC) conditions, which limit primary production. ... -
The Effects of Lead (II) Nitrate on EPS Production by Colwellia psychrerythraea 34H and the Metal-Binding Capacity of the EPS under Freezing Conditions
(2017-07-24)We examined how [Pb2+] affects the growth of the bacterium, Colwellia psychrerythraea as well as the bacterium’s ability to produce extracellular polysaccharide substances (EPS). In addition, we explored the potential ... -
Effects of Low Oxygen Levels on Copepod Size Distribution with Depth in Hood Canal
(2019)Hypoxia is a condition affecting marine trophic webs throughout the world’s oceans. In Hood Canal, Puget Sound is a basin that experiences seasonal hypoxic due to its bathymetry and poor circulation. High primary productivity ... -
Effects of marine channel morphology on sediment depositional characteristics
(2012-06)[Author's Abstract] Understanding how the shape of marine channels controls the patter of sediment deposited within them can help explain the relationship between seafloor channels and terrestrial rivers. Also, marine ... -
Effects of Nitrate/Nitrites on coral bleaching: Coral Reef health around the Hawaiian Islands
(2011-03)This study involved collecting images and water samples from various locations around Hawaii’s main islands. Images were collected around the Big Island (Hawaii) and Molokini Crater for visual comparison of coral health. ... -
The effects of nutrient additions to phytoplankton size structures based on chlorophyll in the Equatorial Pacific Ocean
(2023-06)Phytoplankton, the primary producers of ocean, have produced over half of the oxygen in the atmosphere and use dissolved carbon dioxide to accumulate biomass which is critical to the biological pump. In High-Nutrient, ... -
The Effects of Ocean Tides on Suspended Surface Sediments in the Amazon River Using In-Situ Sampling and Satellite Imaging
(2017-07)The Amazon tidal river consists of the lowermost 800 km of the Amazon River that is affected by tides. The effect of tides on surface suspended sediment concentration (SSC) in the Amazon has not yet been characterized, ...
