This report describes the results of detailed statistical analysis of sea clutter data that were collected during the ESRL 38/97 trial, which was held off the Northern Australian coastline in February 1999. One of the trial's main objectives was to contribute to a database of experimentally collected clutter returns with radar system parameters that are comparable to those used in the Elta EL/M...
This paper introduces a new approach for utilizing the multi-resolution wavelet decomposing for shoreline change rate detection from RADARSAT-1 SAR image. The wavelet approximation of the Two RADARSAT-1 SAR images (1998-2004) defined by the sum two-dimensional wavelet functions at different scales and locations. The raw RADARSAT-1 SAR images were decomposed into a low and high frequencies image...
The Mediterranean mussel Mytilus galloprovincialis (L.) was collected from the fall 2005 to the winter 2009 from the six sites on the Montenegrin coastline. Two wild samples were collected from the open sea coastline, and two cultivated and two wild were from the Boka Kotorska Bay. The mussels soft tissue was analyzed for zinc, copper, lead, cadmium, arsenic and total mercury. Concentrations of...
A quantitative analysis of microplastic pollution along the south-eastern coastline of South Africa.
The extent of microplastic pollution (<5mm) in the southern hemisphere, particularly southern Africa, is largely unknown. This study aimed to evaluate microplastic pollution along the south-eastern coastline of South Africa, looking at whether bays are characterised by higher microplastic densities than open stretches of coastline in both beach sediment and surf-zone water. Microplastic (mean ±...
MESERVEY, R., 1971. The coastline fit of Africa and South America. Palaeogeography, Palaeoclimatol., Palaeoecol., 9: 233-243. It has become axiomatic that the pre-drift reconstruction of Africa and South America is to be made by fitting together the continental shelves. Although this procedure is very plausible, actually the detailed fit of the coastlines is better than that of the shelves and ...
Water corrosivity in Gdansk Bay, Poland, the southern part of the Baltic Sea, was investigated. The analysed region is heavily industrialized, and the coastline is very diverse. Twenty-seven test points along the coastline were selected. Water parameters such as salinity, total dissolved solids content, resistivity, conductivity, oxygenation, pH and corrosion rate were determined. The results o...
This study uses a unique integration of geospatial and hedonic property data to estimate the impact of sea-level rise on coastal real estate in North Carolina. North Carolina’s coastal plain is one of several large terrestrial systems around the world threatened by rising sealevels. High-resolution topographic LIDAR (Light Detection and Ranging) data are used to provide accurate inundation maps...
Shoreline change was identified as a vital sign for the Southwest Alaska Monitoring Network because land loss or gain at the marine edge has important ecological and jurisdictional implications to resource managers of coastal National Parks. To evaluate the type of shoreline changes occurring along the 82 km coastline of Lake Clark National Park and Preserve, 7 of 10 cross-shore beach profiles ...
