Wind-Driven Sea Surface Wave and Coastal Water Level Dynamics Across Different Spatial Scales
… propagate over long distances towards vulnerable coastal regions. Complex factors that impact the properties of surface waves, including wind, topography, and water levels, must be incorporated into numerical models to achieve accurate simulations of the wave climate. Predictions of the offshore …

Utility of remote sensing data in retrieval of water quality consituents concentrations in coastal water of New Jersey
… important optical properties used for monitoring coastal water quality are the concentrations of chlorophyll (CHL), color dissolved organic matter (CDOM) and total suspended materials (TSM). Ocean color remote sensing, a technique to collect color data by detection of upward radiance from a …

Evaluation of storage strategies and techniques for the hydrochemical analysis of nutrients in Atlantic Ocean coastal water samples
Filtered and unfiltered samples of coastal seawater from the Atlantic Ocean (Muizenberg and Llandudno beaches, Cape Town) representing a non upwelling region and an upwelling region respectively were stored at -20 deg C. Deviations in the concentrations of silicate, inorganic phosphate, nitrite, …

A study of the New York / New Jersey coastal water : bio-optical characteristics of the harbor estuary and the effects of heavy metals on brown tide alga of the bight
The New York / New Jersey (NY/NJ) coastal area is one of the most productive regions around the world and a major natural and scenic resource for New York and New Jersey. As a result of excessive nutrient loading in the water, algal blooms have been observed since 1950's. The NY/NJ coastal area …

A sea of contested evidence: Disputes over coastal pollution in Hout Bay, Cape Town, South Africa
The City of Cape Town's (CoCT) wastewater management system discharges effluent from households, industries and other sources into the Atlantic Ocean through deep-water marine outfalls in Green Point, Camps Bay and Hout Bay. At total capacity, these three outfalls discharge 55.3 megalitres (Ml) …

The structure of the Kuroshio west of Kyushu
… during January, 1986 in order to investigate the water properties and flow field in the Kuroshio. A similar CTD survey was made in July, 1986 aboard the R/V Washington to study the seasonal variability in the Kuroshio. The Kuroshio in this region exhibited a marked seasonal change in its …

Radium cycling in groundwater : implications for bioremediation and tracer studies
… health risks. While occurrence of Ra in groundwater is concerning for public health and safety reasons, Ra is also a powerful tracer for calculating groundwater discharge and pollutant loading to coastal water. In this thesis, I investigate processes controlling Ra mobility in groundwater that …

Modern sedimentation in the Northern Barents Sea : input, dipersal and deposition of suspended sediments from glacial meltwater
… flour is supplied by several large stable meltwater outflow locations along the ice front. Because the water is fresh and nearly the same temperature as the ambient coastal water, it is bouyant. Although the traction load deposits as the meltwater plume rises to the sea surface, sand (as well …

Dynamics, interactions and ecosystem implications of mesoscale eddies formed in the southern region of Madagascar
… identical to those occurring in the Madagascan coastal water although the reason for this is unknown. It has been proposed that eddies act as a vector of transport for planktonic larvae from the Madagascar island to the southern African east coast. In this study it is shown that eddies spawned …
