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...
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...
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...
Over the past few decades, Southeast Australia has experienced severe regional climatic events, including devastating floods and some of the most extreme droughts on record, linked in part to influences from both the El Niño Southern...
This research project seeks to evaluate the rainfall forecast accuracy of the GEFS (Global Ensemble Forecast System) following the 2010 model update, analyzing the Atlantic September 2010 Hurricane Karl as a case study. Archived...
Ice and snow particles have a great, yet poorly understood impact on the Earth's climate system. One of the difficulties of studying snow particles is their irregular shape. While spheres and even oblate spheroids backscatter radiation...
The Great Smokey Group and the Mineral Bluff Group of the southern Appalachians Blue Ridge contain units of metaconglomerate that contain stretched quartz pebbles. Quartz pebbles have been widely used as strain markers in conglomerates....
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...
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...
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...
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...
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...
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 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...
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 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...
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 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...
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...
The advent of ensembles permits forecasters to have an implied level of confidence based upon the level of (dis)agreement among those ensembles. However, there are occasionally situations where the ensemble members may agree but be in...
Metallic nodules are common in metamorphosed ordinary chondrites. The origin of metal nodules has been debated because the mechanism of the formation of metal nodules is not known. Several proposed scenarios, e.g., the metal nodules and...
In this paper we examine the variations of the boreal summer season sea breeze circulation along the Florida panhandle coast from relatively high resolution (10 km) regional climate model integrations. The 23 year climatology (1979-2001)...
Sea Surface Temperatures (SSTs) are an important measure of our current weather and climate, as well as an essential variable in both short and long term weather forecasting. Infrared SST retrievals are reliant on passive sensors, and...
Anthropogenic pollution impacts many of the Earth's natural processes. Therefore, understanding the mechanisms that transport pollutants from the surface to the free atmosphere is important for understanding the chemical composition of...
A new metric for identifying severe tornado (F3+) alleys is presented. Regions are distinguished by average F-scale values with a minimum of 15 severe tornado events within 200km. Five distinct "severe tornado alleys" are described...
A data assimilation method is developed to calibrate a heterogeneous hydraulic conductivity field conditioning on observation of a transient groundwater flow field or transient conservative solute transport field. An ensemble Kalman...
Ocean turbulence is responsible for stirring and spreading ocean tracers, and contributes to the mean circulation as eddy bolus fluxes. The influence of the eddies on the mean circulation becomes particularly important in regions where...
Florida is typically considered to be tectonically stable and representative of global eustatic sea level with little evidence for any anomalous local subsidence or uplift during the late Cenozoic. Sea level during most of that time did...
The input of potential vorticity (PV) over the Oceans is estimated from observations to produce a climatological map of PV flux and to study the interannual forcing variability. Particular attention is paid to the North Atlantic...
This study presents the first high-resolution long-term history of seawater lithium isotope ratio (δ7LiSW) reconstructed from analyses of chemically cleaned planktonic foraminifera. The lithium isotope ratio of seawater (δ7LiSW ~31.0‰)...
A karst aquifer is a carbonate aquifer where groundwater flow dominantly occurs through bedding planes, fractures, conduits, and caves created by and/or enlarged by dissolution. Conventional groundwater modeling methods assume that...
This study is focused on the application of 222Rn (radon, t1/2=3.8 d) as a geochemical tracer for evaluation groundwater fluxes in different aquatic systems including submarine springs and lakes. For this purpose improvements of some...
The ridge systems that frame the Lau Basin and Havre Trough, located east of Fiji and north of New Zealand, separating a large counterclockwise gyre at the surface into two smaller gyres at depth. A strong deep western boundary current ...
