Segregation Of Palaemonid Shrimp Along The Shark River Estuary: Implications For Trophic Function, Lauren C. Mccarthy

HCNSO Student Theses and Dissertations

This study examined the abundance, distribution, and spatiotemporal variation of palaemonid shrimp species in relation to season and salinity in the Shark River Estuary, Everglades National Park (ENP), Florida, USA. Five palaemonid species occurred in the samples: Palaemonetes paludosus, P. pugio, P. intermedius, Palaemon floridanus, and Leander paulensis; L. paulensis was collected only during the wet season. Overall, shrimp catches in traps doubled in the dry season. Catches in the upper estuary were dominated by P. paludosus, particularly in the wet season, while catch per unit effort (CPUE) at the most downstream, …

Analysis Of The Neutral Wind Profiles From The Hex Ii Experiment, Tyler Scott

All Theses

The HEX II sounding rocket experiment was carried out on February 14, 2007, during active geomagnetic conditions. Three rockets released trimethyl aluminum (TMA) chemical tracer trails to measure the neutral winds. Three neutral wind profiles obtained from the upleg trails are presented. The profiles are characterized by a strong wind peak around 113 km altitude in the northwestward direction. Below the peak, the winds exhibit strong shear and a smaller wind peak at around 103 km in the southeastward direction. The wind magnitudes are too strong to be attributed to tidal forcing. Above 120 km the winds are consistently to …

It is designed to produce and provide gridded fields of urban canopy parameters for various new and advanced descriptions of model …

Mechanisms For Temporal Change In Phytoplankton Composition In San Luis Obispo Bay California, Marc T. Tognazzini

Master's Theses

Coastal topography and more specifically, the impact of local hydrography can significantly influence phytoplankton dynamics along the California coast. In San Luis Obispo Bay California, the local hydrography is influenced by the presence of a lee and proposed upwelling shadow in the northwest corner of the bay. These conditions allow for periods of unperturbed phytoplankton growth creating phytoplankton incubation areas. Phytoplankton dynamics including accumulation, advection, and composition were examined in San Luis Obispo Bay California from January to June 2004 using all the primary techniques of ocean monitoring encompassed in the coastal module of the Global Ocean Observing System. These …

The Very Basics Of Sustainability - An Alternative Viewpoint (Slides With Audio) (Large File! To Speed Up Download, Right-Click On "Download" Link To Save To Own Pc.), Jim Mcgovern

Other resources

This presentation sets out the very basics of ‘sustainability’, although a definition of sustainability is not attempted. Some of the very basics are the context in which the Earth and humankind exist in space and time, the Earth’s climate, the Earth’s population and humankind’s options and choices. The author advocates keeping an open mind on all available options, including the use of oil, gas, coal, tar sands, carbon capture and sequestration, nuclear power etc., as well as the technologies that are more widely considered ‘green’. The author also argues that, in addressing the challenges that humankind faces, globally concerted effort …

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Because deep-sea fisheries are increasing as coastal fisheries decline, fisheries scientists need baseline data on deep-sea ecosystems prior to further development of deep-water fisheries. We present preliminary results and ongoing efforts to characterize the trophic structure and energy flow of the pelagic ecosystems of the northern Mid-Atlantic Ridge, from Iceland to the Azores. This study is one component of the international CoML field project MAR-ECO (www.mar-eco.no). We found a diverse deep-pelagic fish fauna (205 spp.), with unexpectedly high bathypelagic fish biomass and spatial complexity. Based on literature reports of species present, crustacean planktivory is the dominant trophic guild (79% of …

Spatial Distributions Of Bathypelagic Fishes Along The Mid-Atlantic Ridge, C. I. H. Anderson, J. Horne, Tracey Sutton

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The spatial distribution of organisms plays a key role in facilitating biological processes, such as trophic interactions, which influence pelagic ecosystem structure and function. This study combines discrete trawl net sampling with continuous, full water column, acoustic measurements to investigate the distribution of bathypelagic (1000- 3000 m depth) nekton biomass along the Mid-Atlantic Ridge from Iceland to the Azores in the North Atlantic. Two, previously unknown, distinct bathypelagic acoustic scattering layers (ASLs) were observed using 18 kHz echosounder data. One, extending down on average ~200 m from 2000 m depth, appears ubiquitous wherever bottom depth allows, while the second, found …

Testing And Application Of Surrogate Surfaces For Understanding Potential Gaseous Oxidized Mercury Dry Deposition, Seth N. Lyman, Mae Sexauer Gustin, Eric M. Prestbo, Phillip I. Kilner, Eric Edgerton, Ben Hartsell

USU Uintah Basin Faculty Publications

Currently there is no standard method for measurement of atmospheric mercury dry deposition. While all operationally defined forms of atmospheric mercury (elemental, oxidized, and particulate) can be dry deposited, oxidized forms are of concern due to high deposition velocities, water solubility, and reactivity. This paper describes the development of a surrogate surface for characterizing potential dry deposition of gaseous oxidized mercury (GOM). Laboratory tests showed that the surface collected HgCl2, HgBr2, and HgO with equal efficiency, and deposition was not significantly influenced by temperature, humidity, or ozone concentrations. Deposition of mercury to surfaces in field deployments was correlated with GOM …

Habitat Mapping In The Farasan Islands (Saudi Arabia) Using Casi And Quickbird Imagery, Gwilym Rowlands, James A. Goodman, Bernhard Riegl, Philip Renaud, Samuel J. Purkis

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Map products derived from remote sensing technology increase our understanding and ability to manage tropical marine environments. The enhanced mapping capabilities of hyperspectral sensors are well understood; yet technology uptake, particularly for large scale tasks, has been slow. The study presented represents one of the largest hyperspectral projects to date, and paves the way towards increased use of this technology. Hyperspectral CASI-550 imagery and multispectral QuickBird imagery, was acquired over 3,168 km² of the Farasan Islands. In addition to the typical image processing steps, inopportune water condensation in the CASI sensors lens necessitated further processing to remove an across-track …

Surface Mucous As A Source Of Genomic Dna From Atlantic Billfishes (Istiophoridae) And Swordfish (Xiphiidae), John P. Hoolihan, Nerida G. Wilson, Ronald M. Faugue, Andrea Bernard, Rebekah L. Horn, Derke Snodgrass, Duane R. Schultz

Marine & Environmental Sciences Faculty Articles

Procedures for sampling genomic DNA from live billfishes involve manual restraint and tissue excision that can be difficult to carry out and may produce stresses that affect fish survival. We examined the collection of surface mucous as a less invasive alternative method for sourcing genomic DNA by comparing it to autologous muscle tissue samples from Atlantic blue marlin (Makaira nigricans), white marlin (Tetrapturus albidus), sailfish (Istiophorus platypterus), and swordfish (Xiphias gladius). Purified DNA from mucous was comparable to muscle and was suitable for conventional polymerase chain reaction, random amplified polymorphic DNA analysis, …

City Of Gloucester Harbor Plan & Designated Port Area Master Plan, July 2009, Sarah Buck, Greg Ketchen, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

A harbor plan is a waterfront land and water use plan intended to establish the community’s objectives, standards, and policies for guiding public and private utilization of land and of water within and adjacent to the commonwealth’s jurisdiction. The 1999 Gloucester Harbor Plan was chiefly focused on infrastructure improvements for both maritime and visitor oriented industries along the waterfront as a central means of recharging the harbor’s economic engine. Many of the improvements have been completed in the wake of this plan. However, it largely ignored the confusing web of land use regulations that has since emerged as the central …

Changing Fecundity And Reproductive Output In Females Of A Chesapeake Bay Population Of Blue Crab, Callinectes Sapidus, Shannon L. Wells

OES Theses and Dissertations

The Chesapeake Bay blue crab, Callinectes sapidus, is an important species both ecologically and as a fishery. Fishery dependent and independent data indicate that the population declined abruptly in the mid-1990s and has remained low. Previous work prior to the decline in population abundance found a significant relationship between size and fecundity for mature females. As with many heavily fished populations, this population has experienced a reduction in the size at maturity. The objectives of this study were to reassess the fecundity of the population, determine the lipid and protein energy allocated for reproduction, and to examine the concentrations …

Nutrient Limitation On Phytoplankton Growth In The Upper Barataria Basin, Louisiana: Microcosm Bioassays, Ling Ren, Nancy N. Rabalais, R. Eugene Turner, Wendy Morrison, Warren Mendenhall

Faculty Publications

The Davis Pond Diversion (DPD) was constructed to divert Mississippi River (MR) water into the Barataria Basin to reduce the salinity in support of wetland restoration on the Louisiana coast. To assess the phytoplankton nutrient limitation in adjacent water systems and potential impacts of DPD, 12 seasonal nutrient-phytoplankton bioassay experiments were conducted from October 2003 to July 2004 using the natural phytoplankton assemblages from freshwater and brackish-water lakes, Cataouatche and Salvador, LA (USA), which receive Mississippi River water from the DPD, and from a nearby freshwater lake, Lac des Allemands, that does not. Dissolved inorganic nitrogen (N), phosphorus (P), and …
