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 ... -
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 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 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 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, ... -
Effects of populated towns on water quality in neighboring Galàpagos bays
(2006-03)Human activities profoundly influence the global cycles of nutrient transport coastal waters. Because of this, dissolved nutrient levels were studied in three Galàpagos Island bays (Academy Bay, Turtle Bay, and Wreck Bay) ... -
The effects of sill-circulation on zooplankton patchiness
(2015-06)[author abstract] Fine scale zooplankton patchiness is an important component of similarly scaled trophic interactions. There are biological and physical drivers of patchiness--this study focused on the physical component, ... -
The effects of suspended glacial sediments on light attenuation and primary productivity in Glacier Bay National Park, Alaska
(School of Oceanography, University of Washington, 2008-06-19)Glacial flour, or the sedimentation resulting from glacial runoff, attenuates light and therefore productivity in the sea. Measurements of primary productivity and light were taken in Glacier Bay to determine the effect ... -
Endocrine disrupting chemical (EDC) accumulation in Puget Sound sediments and the implications for native fish populations
(School of Oceanography, University of Washington, 2008-06-19)Sediments from Glacier Bay and Puget Sound, Washington were analyzed for the presence of natural and synthetic estrogens and progestogens. Glacier Bay had low concentrations and Puget Sound had high concentrations. The ... -
Environmental controls on zooplankton composition and distribution in Muchalat Inlet, Nootka Sound, B.C., Canada
(2016-06)[author abstract] This study investigates environmental controls on zooplankton populations within the estuarine Muchalat Inlet fjord basin in Nootka Sound, B.C., Canada. Five stations were sampled ... -
Environmental impact assessment: looking at sediments in Nootka Sound for traces of pulp mill effluent
(2015-06)[author abstract] The production of pulp, a paper product, involves a combination of chemical washes and combustion processes that are known sources of many persistent organic pollutants that can bio-accumulate in the ... -
Environmental influences on the distribution of sediment within a water column at a tidewater glacier, Jorge Montt
(2010-05)The purpose of this study was to determine how certain factors present in the environment helped to direct the distribution of sediment within the water column at the Jorge Montt glacier in Chile. The developing behaviour ... -
Establishing a link between bacterial distribution and nutrient variation
(2010-05-07)The purpose of this research was to study the variation in bacterial communities along with variation in the natural environment. By doing so, it becomes possible to establish connections between different bacteria species ...
