The purpose of this study is to test a perfect prognosis scheme used to develop lightning guidance for the warm season (May-September) for three regions of the country (Colorado, Washington, D.C., and Oregon). This guidance product is...
Applications of Calcareous Nannofossils and Stable Isotopes to Cenozoic Paleoceanography: Examples from the Eastern Equatorial Pacific, Western Equatorial Atlantic and Southern Indian Oceans
This dissertation is a collection of five calcareous nannofossil and one stable isotope studies on materials from Ocean Drilling Program (ODP) Legs 183 (Site 1135), 206 (Site 1256), and 207 (Site 1259) that target two important...
The community abundance and diversity of mRNA transcripts for sulfate-reducing prokaryotes were investigated in parallel with rate measurements of sulfate reduction activity in marine subsurface sediments of Aarhus Bay, Denmark. Solid...
Laboratory experiments on a rotating tank of fluid are used to study the fundamental aspects of geophysical fluid flows. The present set of experiments are an attempt to study the effect of a rectangular ridge on the flow of a rotating...
Southern Alaska crustal exposures provide an excellent opportunity to study the growth of collisional continental margins through the processes of terrane accretion, magmatism, accretionary prism development, and subduction of oceanic...
This research involves the creation of a new storm surge index that incorporates many variables important in storm surge generation like maximum winds, radius of maximum winds, pressure, translation speed, and bathymetry. Using a two...
The Florida Big Bend region in the northeastern Gulf of Mexico contains both spawning sites and nursery habitats for a variety of economically valuable marine species. One species, the gag grouper (Mycteroperca microlepis), relies on the...
A large fraction of the continental shelf is covered by permeable sediments that are flushed by wave, wind, and tide generated bottom currents. Elevated dissolved organic carbon (DOC) concentrations in coastal zones, a diverse and...
The deep-sea, soft-bottom habitat is considered the largest ecosystem on Earth, yet little is known about the biogeography of the infauna. This dissertation examines the species' ranges of the meiofaunal taxon Harpacticoida (Crustacea:...
Ice clouds play an important role in earth radiation balance by reflecting solar and absorbing thermal radiation, the so-called albedo versus greenhouse eects, which cause signicant dierential atmospheric heating and cooling in...
Understanding and predicting the evolution of the tropical cyclone (TC) inner-core continues to be a major research focus in tropical meteorology. Eyewall slope and its relationship to intensity and intensity change is one example that...
Rapid intensity changes in hurricanes have been the focus of many publications. Understanding how and why these storms intensify has been the goal of many meteorologists over the last few years. This study explores the energetics of Psi...
The oceanic mixed layer is a region of intense mixing, where turbulence homogenizes vertical temperature and salinity distributions down to depths of O(100) m. Below the mixed layer, in the upper layers of the stratified thermocline, ...
The land/sea warming contrast being greater than unity is a well-known phenomenon in response to anthropogenic radiative forcing. The land/sea surface warming asymmetry is essentially a result of the differing surface and boundary layer...
Seamounts are one of the largest biomes on earth, yet remain one of the least explored. They are known to be centers of increased biomass, species richness, endemism and speciation as well as areas of distinct community structure, as...
Satellite data is compared to objectively analyzed wind data from the Hurricane Research Division's H*Wind software to attempt to quantify the value that satellite data could bring to the objective analysis. Previous research (DiNapoli...
Nitrogen (N) is often a limiting nutrient for primary productivity in the ocean and plays a critical role in the global carbon cycle. Fixation of N2 into reactive N (Nr) by photosynthetic prokaryotes in surface waters is a primary source...
The Hengchun Peninsula (HCP) of southern Taiwan represents the newest emergent segment of the orogen built by the ongoing oblique collision between the Luzon arc and Eurasia continent. Newly recognized exposures indicate that a unit with...
Groundwater-surface water interactions in lakes have been gaining attention in recent years as scientists have recognized the potential significance that groundwater has as a source of nutrients and contaminants to aquatic ecosystems....
In this study, we have diagnosed diabatic heating, meridional adiabatic mass and angular momentum transport, and downward transfer of westerly angular momentum by the pressure torque in isentropic coordinates using daily NCEP-NCAR...
The Tongue of the Ocean (TOTO) region located within the Bahamas archipelago is a relatively under-studied region in terms of both its biological and physical oceanographic characteristics. This region is comprised of a deep trough along...
ABSTRACT This work presents turbulence data collected in the Gulf of Mexico in an attempt to quantify the source or sources of turbulent dissipation along the continental shelf and any possible causes for its seasonal change. In addition...
The geostationary satellite television (TV) signals that are reflected off the ocean surfaces could enter the AMSR-E antenna, resulting in RFI (Radio Frequency Interference) contamination in AMSR-E 10.65 and 18.7 GHz channels. If not...
Riverine inputs, groundwater efflux, and terrestrial runoff enrich coastal waters with silica. Diatoms, which require silicic acid (Si(OH)4) for frustule formation and cell growth, are therefore predominantly found in these waters. Less...
State of the art fully three-dimensional ocean models are very computationally expensive and their adjoints are even more resource intensive. However, many features of interest are approximated by the first baroclinic mode over much of...
Anthropogenic emissions are transported both locally and globally. Depending on the magnitude of the transport, the emissions can have varying impacts on air quality and atmospheric chemistry. Transport occurs most efficiently if...
A greatly expanded section of Holocene sediment was recovered at Site NBP0602-8 in the Firth of Tay near the tip of the West Antarctic Peninsula during the SHALDRIL II cruise aboard the R/V Nathaniel B. Palmer, 2006. Recovery in the four...
It has been suggested in older and recent literature that a broad deep eastern boundary flow is linking the equatorial Pacific Ocean to the Southern Ocean. The depth range of this flow corresponds to the Pacific Deep Water (2500m) where...
Modern (farmed) calcite in Hollow Ridge Cave, Marianna, FL, USA was cultivated seasonally and analyzed for isotopic composition (δ18O and δ13C). Simultaneous in situ cave-air chemistry, drip water composition, and micrometeorology were...
Bacteria serve as traditional indicators of water quality. In the past decade, methods have been developed to explore the use of more human specific indicators. One of these suggested indicators is caffeine. Caffeine is widely consumed...
