Long term albacore (Thunnus alalunga) spatio-temporal association with environmental variability in the Northeastern Pacific

Creator:: Phillips, A. Jason
Abstract:: This study investigated long-term (1961-2008) changes in albacore (Thunnus alalunga) abundance and distribution in relation to local environmental and large-scale climate indices in the Northeastern Pacific using time series and spatial analyses. Prior to the time series analysis, a wavelet analysis was conducted to examine nonrandom patterns of cyclical variability...

Development and use of satellite-derived sea-surface temperature data for the nearshore North Pacific and Arctic Oceans : temperature pattern analysis and implications for climate change at ecoregional scale

Creator:: Payne, Meredith C.
Abstract:: The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. Recent research indicates that there has been a warming trend in ocean temperatures over the last...

Geochemical and helium isotopic variability within the Lau Basin

Creator:: Goddard, Charlotte Ives
Abstract:: This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...

Exploring a fluorescence-based analytical method for Ba in natural waters and a field study of the major ion chemistry of Lake Issyk-Kul, Kyrgyzstan

Creator:: Qiu, Xuemei
Abstract:: Two separate research projects are described here. One involves development of a new analytical method for determination of Ba in seawater and other natural waters. The other is a collaborative field study of the chemistry of Lake Issyk-Kul, Kyrgyzstan. The method project explored an ion chromatography-fluorescence detection bench-top approach for...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Nonlinear internal waves on the continental shelf

Creator:: Shroyer, Emily L.
Abstract:: The properties and evolution of nonlinear internal waves (NLIWs) depend upon the background conditions within which waves form, propagate, and dissipate. As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged...

Turbulence in sheared, salt-fingering favorable environment

Creator:: Kimura, Satoshi
Abstract:: Instability and turbulence in sheared, salt-fingering favorable stratification are studied using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable stratification is gravitationally stable, because the unstable vertical gradient of salinity is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering instability can occur at the interface of these different water-masses....

Sea surface water motion off Chile latitudes18°S-40°S, revealed from satellite images ofchlorophyll and temperature distribution

Creator:: Espinoza, Felix R.
Abstract:: The mesoscale sea-surface circulation pattern within 400 km off Chile and between 18°S and 40°S latitude is described using chlorophyll and temperature images from the Coastal Zone Color Scanner NIMBUS-7 satellite. The data base is a set of four mosaics developed from band-3 (550 nm) images taken on June 4...

Distribution, structure, and function of marine ecological communities in the northern California Current upwelling ecosystem

Creator:: Reese, Douglas Charles
Abstract:: Within systems characterized by substantial spatial and temporal variability, abundances of organisms tend to be higher in localized areas. Within the northern California Current system, the identification of such marine, biological hotspots would be of great importance to resource managers, conservationists, and research planners, and is consequently a growing area...

Utilization of natural and supplemental biofuels for harvesting energy from marine sediments

Creator:: Nielsen, Mark E.
Abstract:: A benthic microbial fuel cell (BMFC) is an electrochemical device that generates current from the redox gradient at the sediment-water interface. Early prototypes had anodes buried in anoxic sediments and cathodes in overlying water. The BMFCs described in this dissertation are based on a chamber design that enables the use...
