Sediment Dynamics in Coastal and Marine Environments: Scientific Advances

Sediment Transport Dynamics in Ports, Estuaries and Other Coastal Environments

Remote Sensing for Marine and Coastal Environments

A scanning lidar system provides high-resolution two-dimensional measurements of ocean wave displacement. The airborne operation further enhances the speed of data acquisition. These properties allow rapid characterization of the ocean wave environment. In addition to active ranging, the scanning optics can obtain passive measurements of surface emissivity, yielding a digital image of the surfa...

Estrogens from sewage in coastal marine environments.

Estrogens are ancient molecules that act as hormones in vertebrates and are biologically active in diverse animal phyla. Sewage contains natural and synthetic estrogens that are detectable in streams, rivers, and lakes. There are no studies reporting the distribution of steroidal estrogens in marine environments. We measured estrogens in sewage, injection-well water, and coastal tropical and of...

Ecotoxicological characterization of marine sediment in Kostrena coastal area.

Samples of marine sediment were taken on 4 selected sites close to the shipyard industry in Kostrena coastal area. Concentration of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and heavy metals (Cu, Pb, Zn, Hg, Fe) were analyzed from chemical-analytical and toxicological aspect. For toxicity detection, the bacterial bioluminescence test (Vibrio fisheri) was used. Co...

Benthic diatom communities of coastal marine environments

This project examined the effects of ecological factors and anthropogenic contaminants on benthic diatom communities near Casey Station, in the Windmill Islands, Antarctica. Preliminary sampling indicated significant compositional differences occurred between diatom communities in bays immediately adjacent to Casey Station and those more distant. Subsequently, a more detailed appraisal of spati...
