To avoid unfavorable seasonal conditions, some species of calanoid copepods produce resting eggs that do not immediately hatch. When buried in the sediment, these eggs can remain viable from weeks to years, and therefore can represent a...
A major theme of recent research is the investigation of the nature of climate variability and the current capability to measure, model, and predict it. This is a formidable task that involves understanding complex interactions and...
The Paleozoic growth of the eastern margin of the North American continent is exemplified by the amalgamation of a series of terranes due to the closure of intervening ocean(s) and the obduction of fragments of oceanic and continental...
Ensemble forecasts are the primary tool used operationally to assess forecast uncertainty. Studies of ensemble forecasts, however, have shown that forecast verifications too frequently lie outside of the ensemble's range of possibilities...
Atmospheric conditions during the dry season of the South American monsoon are instrumental in the initiation of convection during the wet season and are strongly correlated to SSTs within the Atlantic Warm Pool. Subsequently, accurate...
Abstract Photographic transects were taken in 2009 and 2010 on the VK826, VK906 and GB535 lease blocks to quantify the amount of the seafloor covered by living or dead colonies of the deep-sea coral L. pertusa, as well as species...
The impact of Stokes drift, a wave-driven mechanism of mass transport, is investigated for surface oil movement in the Gulf of Mexico. Stokes drift was neglected in trajectory forecasts in the Gulf during the Deepwater Horizon oil spill....
The northern part of the West Florida Shelf (WFS) bends sharply to form Florida's Big Bend coast. Eulerian acoustic Doppler current profiler measurements on this narrowing shelf, the first multiyear in situ measurements in this region, ...
Recent work has shown that variability in the properties and/or transport of Mediterranean Seawaters spilling across the Strait of Gibraltar into the North Atlantic have had little impact on the variability of Mediterranean Outflow Water...
The wind speed and wind stress over the Southern Ocean (SO) is compared from the QSCAT, COAPS, ERA-Int, JRA25 and NCEP2. From the results of comparison, NCEP2 seems to poorly represent wind speed in the SO. In the summer months, the...
Pliocene-Pleistocene Calcareous Nannofossil Biostratigraphy of IODP Hole 1396C Adjacent to Montserrat Island in the Lesser Antilles, Caribbean Sea, Plus Experimentally Induced Diagenesis
Integrated Ocean Drilling Program Hole 1396C, adjacent to Montserrat Island, provides a lower Pliocene to Pleistocene record of calcareous nannofossil assemblages (CN11 to CN15). The nannofossil assemblages are generally common to...
This study investigates the changes in skewness and kurtosis of five atmospheric variables due to a change in the forcing of a primitive equation global circulation model. First, the average, variance, skewness, and kurtosis are...
A diurnal warming model is used create a new data set of global, diurnally varying sea surface temperatures over a five year period from 2000 to 2004. The model is forced with atmospheric bulk variables, precipitation rate, and radiation...
Improving knowledge of air-sea exchanges of heat, momentum, fresh water, and gases is critical to understanding climate, and this is particularly true in high-latitude regions, where anthropogenic climate change is predicted to be...
A method for estimating deep, depth independent current variability is described. The procedure uses XBT derived dynamic heights to remove the near surface signal from altimetric sea surface height (SSH). The difference between SSH and...
Microwave Humidity Sounders (MHS) onboard NOAA-15, -16, -17, -18, -19 and EUMETSAT MetOp-A, -B provide radiance measurements at a single polarization state at any of the five observed frequencies. Microwave Humidity Sounder (MWHS)...
Fire-derived compounds have received considerable attention as a refractory form of dissolved organic carbon (DOC), the largest carbon pool in the ocean. Due to its recalcitrant nature, pyrogenic or black carbon, which is produced by the...
Dinoflagellates are unicellular, eukaryotic organisms that consist of both photosynthetic and non-photosynthetic species. The approximately 91 known species of bioluminescent dinoflagellates are the pre-dominate contributors to ocean...
Stable Carbon and Oxygen Isotopes in Cetaceans and in Terrestrial Herbivores as Indicators of Diet, Movement and Environment: Paleoceanographic, Paleoclimatic and Paleoecologic Applications
Stable oxygen and carbon isotopic compositions of modern and fossil cetacean teeth and bones were analyzed to examine if and how they reflect the diet, habitat preference and migratory patterns of modern whales and to reconstruct the...
Biostratigraphy and Comparison of Paleocene to Lower Eocene Calcareous Nannofossils from Broken Ridge and Ninety-East Ridge: Ocean Drilling Program Leg 121, Sites 752 and 758
Ocean Drilling Program Site 752 on Broken Ridge in the Indian Ocean recovered an expanded section containing Paleocene and lower Eocene calcareous nannofossils. Qualitative counts show a diverse, high-latitude assemblage of primarily...
Lagged correlation of dynamic height from the gappy California Cooperative Oceanic Fisheries Investigation (CalCOFI) with monthly San Diego sea level for the period 1949-2001 shows that the dynamic height propagates westward at 4.10 cm/s...
For many years tropical cyclone superensemble has shown remarkable skill in forecasting Atlantic tropical cyclone track and intensity. In this project tropical cyclone superensemble is applied to Eastern Pacific tropical cyclone...
The inter-annual variability of typhoon landfalls in China is investigated using historical and modern records. A north-to-south anti-correlation in yearly activity is confirmed from the historical records. When activity over Guangdong...
Although tropical cyclone (TC) track forecasts have improved considerably in recent years, predicting their intensity continues to be a challenge for both meteorologists and numerical models. A storm's path is primarily influenced...
The wind-driven oceanic circulation in the presence of bottom topography that isopycnals intersect is examined in an idealized setting. A modified quasi-geostrophic (QG) model has been designed and implemented. The model allows staircase...
Zinc acts as a micronutrient in the ocean, capable of influencing and potentially controlling phytoplankton productivity and community structure. Thus, it is important to quantify the distribution of dissolved Zn in the oceans, in...
Water residence time is an important parameter in defining how an estuary functions. The focus of this research was on the residence time and its implications on environmental health. Radium isotopes (223Ra, 224Ra, 226Ra, 228Ra) have...
I examined the acoustic ecology of coastal bottlenose dolphins (Tursiops truncatus) in the Big Bend region of Florida and compared it to other populations of dolphins found in similar habitats. This region is one of the most acoustically...
There are no IAEA-GNIP stations in Florida. In order to improve our understanding of the proxy climate records preserved in speleothems, tree rings and lake sediments and to explore the utility of stable oxygen and hydrogen isotopes in...
There are two objectives of the present study. The primary objective is to undertake the following research projects involving the Arctic Oscillation (AO), the El Niño Southern Oscillation (ENSO), and the Madden Julian Oscillation (MJO):...
This dissertation examines the role of microorganisms in marine biogeochemical cycles with a particular emphasis on sedimentary nitrogen transformations. Nitrogen is required by all living organisms and is a key nutrient controlling the...
