Investigations were conducted from 15 May 1964 to 3 January 1966 to determine the incidence, distribution, and abundance of marine invertebrate fouling organisms in Hampton Roads, Virginia. Dredging carried out at seven stations revealed that benthic organisms most likely to be involved in fouling were Thuiaria argentea, Alcyonidium verrilli, Microciona prolifera, Amathia vidovici, and Aeverrillia armata. All of these species occur in the Pier 12 berthing area of the Norfolk Naval Base, with. !·...

Microbial communities associated with a particular space or habitat, or microbiomes, play significant roles in host health and the regulation of biogeochemical cycles. In oysters these microbiomes may be important contributors in the removal of biologically available nitrogen (N) from the coastal and marine environment through the process of denitrification. Denitrification is the microbially mediated step-wise reduction of nitrate (NO3-) or nitrite (NO2-) to N2 gas. Excess nitrogen in the Chesa...

A majority of carbon in freshwater and marine ecosystems is in the form of ultraplankton, heterotrophic and autotrophic plankton &<&5 &\mu&m including heterotrophic bacteria, Prochlorococcus, cyanobacteria, and autotrophic eucaryotes. However, ultraplankton and subsequently microbial food webs have yet to be incorporated into models of benthic-pelagic coupling despite the preponderance of macroinvertebrates with the capacity to feed on ultraplankton. I have examined the role of microbial food we...

An experiment was conducted to evaluate the durability, toughness, and strength of Synthetic Fiber Reinforced Concrete after being immersed in five separate environments for one year at FAU SeaTech. The specimens were molded and reinforced with two-inch Polypropylene/Polyethylene Fibers in a concrete aggregate matrix and were cut into identical sizes. Some of these environments had accelerated parameters meant to increase degradation to simulate longevity and imitate harsh environments or seawat...

Textile industries are the major users of dyes in the world. A huge fraction of dyes are discharged out from the textile industries, causing serious damage to the environment. Bioremediation based technologies has been proved to be the most desirable and cost- effective method to counter textile dye pollution. The ability of the microorganisms to decolorize and metabolize dyes can be employed to treat the environment polluted by textile dyes. In this work, a total of 84 bacterial strains were is...

Planktonic organisms form the base of the marine food web and may be impacted by environmental change in many ways. The interactive effects of multiple, simultaneous climate-driven changes on these organisms are not well understood. This dissertation examined the impacts of ocean acidification in combination with other environmental stressors on marine plankton and determined spatial patterns of one of these potential interactive drivers. Chapter 2 investigated the synergistic effects of ocean a...

Adsorption to sinking particulate matter, known as scavenging, is an important yet elusive term in the budgets of many bioactive and contaminant trace metals in the ocean. Scavenging is also involved in the cycling of other trace metals used in ocean sediments to learn about ocean processes, such as circulation rates or biological productivity, of the geologic past. This dissertation is an oceanographic exploration of the naturally-occurring radionuclides 230Th, 232Th and 231Pa aimed to better u...

abstract: Variations of 238U/235U in sedimentary carbonate rocks are being explored as a tool for reconstructing oceanic anoxia through time. However, the fidelity of this novel paleoredox proxy relies on characterization of uranium isotope geochemistry via laboratory experimental studies and field work in modern analog environmental settings. This dissertation systematically examines the fidelity of 238U/235U in sedimentary carbonate rocks as a paleoredox proxy focusing on the following issues:...

Estimating the minimum time since death (minimum Post Mortem Interval, minPMI) is a necessary part of a forensic investigation. Besides the coroner’s assessment of the typical signs of death, minPMI can be estimated using forensic entomology, the scientific discipline that considers insects and other arthropods that colonize the remains. In an aquatic environment, insects, as well as crustaceans, have the potential to provide data regarding the time spent in water of the remains (FT, floating ti...

Thesis (M.B.A)--Boston University / The purpose of this thesis is to analyze the maritime labor costs in connection with their effecta on the industry by three methods of approach: first, to explore the extent of the costs supported by the subsidization policy of the United States Government; second, to evaluate the justifications offered by seamen's unions in support of the wage levels attained by their effortsr and third, to appraise the claims of management in relation to the other two.

Thesis (M.S.)--Boston University / This thesis presents a novel formulation of a gradient-type controller to address the problem of cleaning up marine oil spills. Little work appears to have been done in developing autonomous oil spill clean-up devices, with most research efforts directed toward developing improved oil collection strategies. It does not appear that previous work in this field has included development of control algorithms specific to addressing the problem of deployment strategi...

Carrageenans are sulfated polysaccharides found in the cell walls of red algae with 20 – 30 % of the dry weight coming from sulfate esters. The understanding of how heterotrophic bacteria desulfate and depolymerize carrageenan has become a rather arduous endeavor as there are 15 different classes of carrageenan distinguished by the degree of sulfation and the presence or absence of a unique galactose derivative, the 3,6-anhydro-D-galactose. The depolymerization of carrageenan requires the remova...

Most benthic marine invertebrates have long-lived planktonic ciliated larvae that must feed and grow to reach metamorphosis. Because ciliated cells in animals are unable to divide it is of considerable interest how ciliated larvae are able to grow. To understand how ciliated larvae grow I compared cell proliferation patterns in several species with planktotrophic larvae from five different phyla (Nemertea, Mollusca, Phoronida, Echinodermata, and Annelida). Cell proliferation events were detected...

Magister Pharmaceuticae - Mpharm / Cancer is a major health problem worldwide and killing millions of people each year. The use of natural products as chemotherapeutic agents is well established, however, many of the currently available drugs are associated with undesirable side effects and high toxicity. Furthermore, the development of drug resistant cancers makes the search for anticancer lead compounds a priority. In this study a library of prefractionated marine sponge extracts was establish...

<p> There is a broad perception that many of the greatest knowledge gaps in marine conservation are in understanding and integrating human dimensions. Marine governance must go beyond the rhetoric that conservation will benefit from including human dimensions, and dig deeper into social science disciplines to find specific tools that may be useful. Bennett et al. (2017) advocate for &ldquo;fostering knowledge on the scope and contributions of the social sciences to conservation&rdquo; from the i...

We present the first marine reservoir age and ∆R determination for the island of St. Helena using marine mollusk radiocarbon dates obtained from an historical context of known age. This represents the first marine reservoir age and ∆R determination in the southern Atlantic Ocean within thousands of kilometers of the island. The depletion of 14C in the shells indicates a rather larger reservoir age for that portion of the surface Atlantic than models indicate. The implication is that upwelling ol...

Bacterioplankton provide important ecosystem functions by carrying out biogeochemical cycling of organic matter. Playing an important role in the microbial loop they help remineralize carbon and nutrients. Bacteria also interact with phytoplankton during phytoplankton blooms. However, fundamental understanding on the underlying molecular mechanisms involved in the degradation of phytoplankton-derived organic matter is still in its infancy. Therefore, we analysed data from a mesocosm experiment f...

Seven species of marine phytoplankters assigned to different taxonomic divisions were tested for toxic responses to two different molecular species of selenium known to be prevalent in seawater, selenite and selenate. Selenate proved to be more toxic than selenite, although severe toxicity was only observed at high concentrations (10⁻² and 10⁻³ M) of both selenate and selenite. At these concentrations, growth was completely or severely inhibited in most species tested. In some of the species t...
