The influence of salinity and sea star wasting syndrome on sea star species composition and distribution in Nootka Sound, British Columbia
(2015-06)[author abstract] The effect of salinity and Sea Star Wasting Syndrome on the distribution and composition of sea star species was studied in Nootka Sound. Using an underwater camera survey were conducted over four days ... -
The influence of water column variability and seafloor topography on multibeam bathymetric mapping
(2015-06)[author abstract] The purpose of this study is to identify influences of seafloor topography and variability of sound velocity properties of the water column on the accuracy of multibeam depth estimates. This study examines ... -
Influence of Zooplankton Community Composition on Copepod Diel Vertical Migration in Hood Canal
(2018-05-27)This study observed zooplankton community composition alongside copepod diel vertical migration patterns in order to make conclusions about the relationship between these two factors. Data on zooplankton community, diel ... -
Insights and predictions of Phytoplankton Biomass in Equatorial Pacific using Random Forest Modeling
(2023-06)Phytoplankton biomass drivers are integral to our understanding of how climate change will impact the carbon cycle as photosynthesis and carbon sequestration play a crucial role in mitigating climate change. The equatorial ... -
Instantaneous sediment accumulation rates in Tarr Inlet, Glacier Bay, Alaska
(School of Oceanography, University of Washington, 2008-06-19)The rate at which sediments accumulate in marine waters affects benthic life and sequestration of organic carbon and PAHs. The instantaneous sediment accumulation in Glacier Bay was measured and found to be slower in March ... -
Inter-annual variability of nutrient distribution in the Eastern Tropical North Pacific oxygen deficient zone
(2017-07-24)In Oxygen Deficient Zones (ODZs) in the ocean, anaerobic respiratory processes remove fixed nitrogen from the marine system as nitrogen gas. The expansion of ODZs over time in response to accelerated anthropogenic climate ... -
Inter-island comparison of phytoplankton growth rates and herbivory rates
(2006-03)The marine ecosystem around the Galapagos Archipelago is characterized by regionally high primary production and chlorophyll a concentrations that are uncharacteristic of the surrounding waters of the Eastern Equatorial Pacific. ... -
Internal tides at Cross Seamount
(2011-03)The R.V. Thomas G. Thompson was used to study currents in the North Pacific Ocean over Cross Seamount, a large extinct submarine volcano South of Oahu, Hawai’i. An Acoustic Doppler Current Profiler (ADCP) was used to measure ... -
Interpolating Coastal Shallows via Trends in Terrestrial and Marine Topography
(2018-05-27)Acquiring bathymetry data of coastal shallows in Puget Sound is both an important and difficult task. Puget Sound estuaries contain a large number of processes that dynamically impact coastal topography and communities, ... -
Interpretation of a temperature and salinity section at 180 degrees longitude in relation to the ENSO cycle in the equatorial Pacific for March 2023
(2023-06)El Niño-Southern Oscillation (ENSO), which is the cycle consisting of El Niño and La Niña has major global impacts on climate. El Niño and La Niña are characterized by large changes in temperature in the equatorial ... -
Interpretation of the relationship between benthic fauna, geologic distributions, and methane seeps at Southern Hydrate Ridge, Oregon continental margin
(2016-06)[author abstract] Deposits of methane and their associated seeps are found worldwide along continental margins. These seeps are of importance and increasing interest because their potential as an energy source, their ... -
Interpreting Rainfall Changes as a result of the 8.2 ka Event through δ2H ratios in the El Junco Lake, Galapagos
(2023-05)The most recent major climate perturbation, the “8.2 ka BP Event,” was a result of a mass influx of meltwater from the drainage of Lakes Agassiz and Ojibway into Hudson Bay. An influx of this magnitude has the potential ... -
Interpreting submarine structures for glacial retreat periodicity within Muchalat Inlet in Nootka Sound
(2015-06)[author abstract] At the end of the last glacial maximum a tidewater glacier, as part of the larger Cordilleran Ice Sheet, filled what is now Muchalat Inlet within Nootka Sound on Vancouver Island. As the glacier retreated ... -
The introduction and dissemination of pathogenic bacteria in the coastal waters of southern California and Mexico
(2012-06)[Author's Abstract] I investigated the introduction and dispersion of potentially disease-causing bacteria in the coastal waters of southern California and Mexico between March 16th and March 27th, 2012. These bacteria ... -
Inverse Echo Sounding: Using measured water depth to calculate water temperature and its variation over time
(2011-03)Inverse echo sounding is a new method that, in this investigation, has been used to calculate average temperature difference in the water column over time using the difference in the recorded depth of points on the sea ... -
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 ...
