    Manganese dynamics in surface waters of the eastern Caribbean
    American Geophysical Union (AGU) ; 1993

    Abstract: The rate of photoreductive dissolution of manganese oxide in eastern Caribbean waters appears to be relatively rapid with an approximate linear dependency of dissolution rate on organic content of these waters. From the magnitude of derived absolute dissolution rates it would appear that reductive rather than oxidative processes should dominate transformations of manganese in surface waters though further insight into the reactivity of “naturally occurring” oxides is needed. Oxidation of Mn(II) added to surface water samples is observed and occurs at rates between those observed for coastal and open ocean surface waters by other investigators. Obvious correlations between oxidation rates and water column characteristics such as total bacterial numbers, dissolved (or particulate) manganese concentrations or organic content of surface waters are not evident. Transformations of manganese in the surface waters of the eastern Caribbean appear to be masked by the supply of fresh particulate material presumably, in part at least, from the Orinoco River.

    Trophic importance of a temperate intertidal wetland to resident and itinerant taxa: evidence from multiple stable isotope analyses

    Abstract: Juveniles of commercially important fish species congregate in shallow vegetated estuarine habitats during high tides. Considerable debate has centred on whether the significance of these habitats lies in their provision of greater feeding opportunities, or shelter from predation afforded by greater structural complexity. We tested the hypothesis that an inundated mangrove and saltmarsh wetland provided feeding opportunities for itinerant species, and that the contribution of wetland primary producers and grazing herbivores could be identified in their diet, using stable isotopes of carbon and nitrogen. Potential sources of dietary carbon included mangrove, saltmarsh, seagrass, seagrass epiphytic material and benthic organic material. Saltmarsh plants (mostly Sporobolus virginicus and Juncus kraussii) and fine benthic organic material appeared to be the primary sources of dietary carbon for the resident grazing herbivores in the wetlands, based on IsoSource mixing models. During high tide, species of itinerant fish enter the mangrove and, when inundated, the saltmarsh, and feed primarily on crab larvae and copepods. Fine benthic organic matter, seagrass epiphyte, and C3 and C4 plant materials also supplement the diet of some fish. The crab larvae therefore provide a significant source of nutrition and an important link between the intertidal wetlands and the adjacent estuarine ecosystem. The carnivorous fish Acanthopagrus australis, at the highest trophic level, hunted within or adjacent to the mangrove–saltmarsh wetland and fed on several lower-order consumers within the wetland. The present study highlights the significance of mangrove and saltmarsh wetlands as a feeding habitat for resident grazers and itinerant nekton.

    Tools based on nuclear and isotopic techniques for the management of threatened coastal ecosystems
    Michigan State University Press ; 2009

    Abstract: Elucidation of in situ environmental processes is the key to effective ecosystem management. However, due to the complexity of coastal ecosystems, few tools are available to determine the inter-relationships and rates of these events. It is only when all of the important variables are understood and computationally described that effective ecological risk analysis can be accomplished. Model packages already exist which describe and predict specific coastal processes and further refinement of subroutines and user-interfaces has some value; however the truly significant advances lie in synergistic integration of different codes. Predictive ecological risk analysis requires transport models predicting contaminant concentrations under a range of environmental scenarios and bioaccumulation and trophic-transfer models using keystone species (or critical groups) identified by models elucidating trophic structure. In an attempt to elucidate natural processes, or solve environmental problems, stable and radioisotope tracers have a number of advantages over conventional techniques. Stable isotope studies replace visual observations of prey-predator interactions with statistically interpretable chemical data. Radiotracers provide real time kinetic data on uptake and transfer of specific contaminants and environmental transport processes. The unique assemblage and application of these nuclear and isotopic environmental probes will greatly assist in effective ecological risk assessment of present situations and the resource-economic evaluation of proposed management options. The nuclear-based technologies developed from studies undertaken in the Sydney (Australia) environs are transferred to developing countries via the IAEA/Regional Cooperative Agreement (RCA) Project: Improving Regional Capacity for Assessment, Planning and Responding to Aquatic Environmental Emergencies (RAS/8/095). The IAEA Project objectives were to improve the regional capacity for the management of aquatic radiological and environmental risks and to develop capabilities in the RCA countries to assess, plan and respond to pollution events in aquatic environments. Expert missions supported national projects in individual Member States, further developing and transferring skills and technologies.

    Abstract: Both the ability of membrane filters to retain iron added (as both Fe(II) and Fe(III)) to surface waters from various sources, and the ability of near ultraviolet light to induce dissolution of colloidal iron oxides suspended in waters from different locations are examined here. In brief, the presence of naturally occurring organic matter exerts a dominating effect on the tendency of iron oxide particles to interact with each other (both in suspension and on or within the membrane matrix). In coastal waters in the vicinity of the Orinoco River, growth of iron oxide particles initiated on addition of either Fe(II) or Fe(III) to the sample of interest, is significantly retarded in comparison to iron particle growth in open ocean waters. Near‐UV light appears to retard particle growth following both Fe(II) and Fe(III) addition to a coastal sample but does little to induce the dissolution of colloidal oxides.
