The formation of cold core filaments on an idealized continental shelf is investigated using a numerical model to simulate the ocean's response to surface cooling. A horizontal density gradient forms because of uneven buoyancy loss due...
Denitrification in coastal sediments is a process of significant scientific interest and a major concern in coastal management. Reliable estimates of denitrification in coastal ecosystems are unavailable due in large part to a lack of...
Offshore resource assessment relies on estimating wind speeds at turbine hub height using observations typically made at substantially lower height. The methods used to adjust from observed wind speeds to hub height can impact resource...
The objective of this study was to investigate oxygen consumption rates in permeable Gulf coast sediments and their link to changes in the water and sediment chlorophyll concentrations. The investigation was initiated to improve our...
Recent, recurrent, and extreme weather events have been a cause for concern over the Eastern Caribbean (EC). Given the dependence on rainfall of agriculture, the main stay of the fragile economies throughout the region, accurate and...
A composite study is presented analyzing the influence of upper-tropospheric troughs on the evolution of precipitation in twelve Atlantic tropical cyclones (TCs) between the years 2000 – 2005. The TRMM Multi-Satellite Precipitation...
Submarine groundwater discharge (SGD) is an important pathway for trace element and nutrient cycling in the coastal ocean. I use a combination of hydrological and geochemical tracer observations to gain insights into the natural and...
The nutrient-rich waters of the Amazon River plume (ARP) support dense blooms of diatom-diazotroph assemblages (DDAs) that introduce large quantities of new nitrogen to the planktonic ecosystem and, unlike other nitrogen-fixers, are...
The tectonic separation of Australia from Antarctica is a key constraint on the development of the Antarctic Circumpolar Current (ACC) during the Cenozoic. The ACC plays a critical role in global climate thermally isolating Antarctica...
The foredunes at twenty locations on Santa Rosa Island, Florida have been eroded to varying degree in response to Hurricanes Opal (1995), Ivan (2004) and Dennis (2005). At locations where pre-storm foredunes were high and the island was...
Deep-sea meiofauna along the continental rise off the west coast of North America are nearly unstudied. To begin to remedy this situation, I sampled each of four regions (off Oregon and off northern, central, and southern California) for...
Inserting an externally defined (i.e., synthetic) tropical cyclone (TC) vortex into numerical weather prediction (NWP) model analyses requires that an existing TC vortex first be removed. Similarly, statistical-dynamical forecasting...
Initializing Coupled General Circulation Models (CGCMs) for routine seasonal ENSO prediction is currently an onerous task. This is one of the main reasons on why the CGCMs participating in the Coupled Model Intercomparison Project 5 ...
TOPEX/Poseidon (T/P) sea surface height (SSH) measurements along tracks 91 and 15 crossing the West Florida Shelf (WFS) are used to estimate seasonal across-shelf SSH gradients. These gradients and the knowledge that geostrophic flow...
Heat fluxes at the air-sea interface are an important component of the Earth's heat budget. In addition, they are an integral factor in determining the sea surface temperature (SST) evolution of the oceans. Different representations of...
This study aims to unravel the driving factors of rainfall variability on interannual time-scales and for extreme events over western equatorial Africa (WEA). We first defined homogeneous and contiguous regions with respect to...
This study examines the impact of anomalous differential generation of available potential energy by absorbing aerosols on the transition and early active phases of the south Asian summer monsoon. Aerosol direct and indirect effects...
Paleoceanographic proxy data indicate that the Agulhas leakage into the South Atlantic was dramatically reduced during glacial times. In our former papers, we suggested that this was due to a northward shift of the zero wind stress curl...
Unlike conventional and satellite observations, the Global Positioning System (GPS) radio occultation (RO) techniques provide all-weather, high-vertical-resolution observations that require no calibration. In this dissertation, the...
The subject of localized topographic circulation has received much attention in the past, in particular Taylor columns have been extensively studied and several observations indicate their existence in the real ocean. In contrast, we...
A local, regime-dependent cloud mask (CM) algorithm is developed for isolating cloud-free pixels from cloudy pixels for Geostationary Operational Environmental Satellite (GOES) imager radiance assimilation using mesoscale forecast models...
Physics-based models are often described by partial differential equations (PDEs) involving more than one independent variable, for example, space and time. Solving these PDEs is critical to understanding the behavior of the physical...
Though a large fraction of primary production and organic matter cycling in the oceans occurs on continental shelves dominated by sandy deposits, the microbial communities associated with permeable shelf sediments remain poorly...
We will describe the development of a high-resolution, gridded forecast guidance product for warm season cloud-to-ground (CG) lightning in Florida. Four warm seasons of analysis data from the 20-km Rapid Update Cycle (RUC) and lightning...
During the past two decades, the accuracy of rainfall retrieval based on passive microwave observations has been greatly improved, particularly over ocean. However, rainfall retrieval over land remains to be problematic. The objective of...
The structure of a tropical cyclone (TC) is a spatial representation of its organizational pattern and distribution of energy acquisition and release. This fingerprint depicts a specific phase in the TC's meteorological lifecycle, ...
Community Structure of Benthic Invertebrates on Necker Ridge in the North Pacific: Distribution, Diversity, and Preliminary Comparison to the Hawaiian Archipelago
In shallow water the Hawaiian Archipelago is one of the most isolated archipelagos in the world, but at depth it may be connected to the vastly understudied seamount-rich region of the central and western Pacific by Necker Ridge, an...
Despite the fact that latent heating in cloud systems drives many atmospheric circulations, including tropical cyclones, little is known of its magnitude and structure, largely because of inadequate observations. In this work, a...
Submarine groundwater discharge (SGD) is a major pathway for nutrient transport in coastal marine systems. There are indications that SGD may also release large amounts of dissolved organic matter (DOM) to the coastal ocean and thus...
