Dynamics and kinematics of an estuarine network
… have multiple connections to the ocean, multiple freshwater sources, and often contain complex junctions between estuarine segments. The Newark Bay estuarine network is connected to the sea through two tidal straits, and is fed by multiple internal and external sources of fresh water. The …

The Impacts of External Nutrient Sources on Marine Phytoplankton in an Eastern Shore Sea-Side Estuary
… dominated by large river systems. Instead, small freshwater creeks influence many coastal systems yet little information has been documented on their ecological significance. The focus of this research is to identify the biogeochemical and physical interactions within an estuarine water-column and …

Stable Isotopes as Tracers for Freshwater Fluxes into the North Atlantic
… global warming. These changes have affected the freshwater balance of the northern North Atlantic and therefore pose a problem to deep water formation in this region, further impacting the global climate. This thesis uses the quasi-conservative properties of oxygen and hydrogen isotopes in …

A Review of Alternatives to Injection of Petroleum Wastewater from Oil and Gas Extraction
… is likely increasing the toxic contaminants in freshwater sources and contributing to freshwater scarcity despite regulatory guidelines, resulting in negative impacts to aquatic life, soil microbial communities, wildlife, and human communities With the predicted increase in global energy demands …

Hydrodynamics and freshwater diversion within Barataria Basin
… and evaporation over the model domain, and freshwater runoff as point sources. This study is focused on examining the impact of freshwater dispersion from the freshwater sources. Thus, a hydrologic model was developed to estimate runoff. Furthermore grid size was reduced, a new advective …

Development of an acid mine drainage treatment technology and recovery of minerals
… concentrations of toxic metals which can pollute freshwater sources. There is need for development of a technology which treats and recover beneficial minerals from AMD. Samples of AMD, water, sediments from the field and sludge from neutralization batch experiments were characterised for their …

Activities Within a Myotine Bat Community With Emphasis on the Endangered Indiana Bat, Myotis Sodalis
… levels of M. sodalis activity, although standing freshwater sources were most important for foraging during the post-lactation period. Habitat usage also was varied between M. septentrionalis, which favored riparian corridors and forest corridors, and M. lucifugus which favored standing …

Identification of Recharge Source Areas in a Fractured Crystalline-rock Aquifer in Ploemeur, France
… and preserving available groundwater resources within crystalline rocks is pertinent to understanding and predicting resources for ecosystems worldwide. Crystalline-rock aquifers, with favorable structure and climate, can be pumped year-round to meet local domestic demand. The Ploemeur …

Going with the flow : social context, uncertainty and decision-making
Climate change, pollution of freshwater sources, swelling populations, increased per capita consumption, as well as political policies are all threatening water security in communities worldwide. Successful direct and indirect alternative water source AWS projects have been implemented in many …

New evidence for complex mosasaur paleobiology: oxygen isotopes in enamel reveal habitat variation of clidastes from the Mooreville Chalk, Alabama
… mosasaur, possibly resulting from incursion into freshwater sources with low δ18O composition. Semi-regular incursion of the C. propython individual into freshwater suggests that mosasaurs had osmoregulatory function similar to those of their living relatives, sea snakes, who must drink freshwater …

Predicting Plant Zonation in the Salt and Brackish Marshes of Georgia
… is maintained by tidal forces pushing inland and freshwater sources pushing towards the ocean. The first objective of this research was to characterize selected edaphic variables for salt and brackish marshes and determine whether or not there were significant differences between the two marsh …

Using untreated and nanobubble-treated potable and wastewater in mortar
… sector places a significant demand on potable freshwater resources, with more than two billion tonnes of water used each year for producing concrete. The increase in population growth, demand for infrastructure, and climate-induced water scarcity, especially in arid and semi-arid regions such …

Transpiration Electrokinetic Power Generation and Zinc Ion Battery for Autonomous Leak Detection
… in water treatment plants and declining freshwater sources. Additionally, water leaks can create extremely dangerous situations, having been the cause of data center fires, by undetected leaks traveling into battery rooms creating short circuits and extremely dangerous lithium battery …

The effect of the cyanobacterial toxin saxitoxin on neurodevelopment
… shellfish toxins, produced by both marine and freshwater phytoplankton. This group of toxins act by blocking the voltage-gated sodium channels, halting the inflow of sodium ions and the subsequent generation of action potentials. While acute exposure has been well researched, with safety …

Surface functionalized iron oxide nanoparticles for applications in biomedical sciences
… to monitor and remove antibiotic pollutants from freshwater sources and food products. MMIPs are prepared using a microemulsion technique containing vinyl-functionalized iron oxide to selectively bind the model antibiotics erythromycin (ERY) and ciprofloxacin (CPX). The results show that MMIPs …
