Rogue waves off the south/southeastern Brazilian coast

Natural Hazards, 2016
The occurrence of freak waves off the Brazilian coast was investigated through the analysis of data recorded by three buoys deployed in the south/southeast region, at a depth of 200 m. As well documented in the literature, these events are not rare, and more than 700 waves could be classified as abnormal based on the relation between the maximum wave ...

Organochlorine compound accumulation in delphinids from Rio de Janeiro State, southeastern Brazilian coast

Science of The Total Environment, 2012
The present study investigated organochlorine compound levels (PCBs, DDTs and HCB) in blubber samples of six delphinid species from Rio de Janeiro State, southeastern Brazilian coast. The species analyzed inhabit the continental shelf (one killer whale, one false killer whale, two bottlenose dolphins, three rough-toothed dolphins, and four long-beaked ...

Provenance and Transport Processes of Sediments along the Southeastern Brazilian Coast

AIP Conference Proceedings, 2008
Natural gamma radiation measurements of Quaternary sedimentary deposits were performed with the aim of understanding the provenance and transport processes of sediments along the coastal zone of the Brazilian Southeast. The method employs thorium, uranium and potassium as tracers of the mineralogical properties of beach sand minerals, which reflect the

Rhodolith Morphology and the Diversity of Polychaetes Off the Southeastern Brazilian Coast

Journal of Coastal Research, 2012
Rhodoliths modify the physical characteristics of their environment, producing a habitat that can support diverse, associated fauna, where polychaetes often achieve high richness expressed in density and trophic diversity. Nevertheless, there are few studies that describe and identify the fauna associated with this habitat.

New Data on Warrana besnardi, a Tiny Bivalve Mollusk from the Southeastern Brazilian Coast

American Malacological Bulletin, 2020
Warrana besnardi (Klappenbach, 1963) is the single Atlantic species of the genus, and part of the family Condylocardiidae, composed of 21 genera and about 150 species. Recent availability of many well-preserved specimens allowed us to perform a detailed study of the shell of this species, using scanning electron microscopy and descriptions of the hinge

In vivoexperimental study to investigate cytogenotoxicity of a contaminated estuary from Southeastern Brazilian Coast

Journal of Environmental Science and Health, Part A, 2021
The aim of this study was to evaluate cytogenotoxicity in mammalian cells induced by ingestion of superficial water from SESS. For this purpose, surface water was collected from two points of SESS: São Vicente Channel (SVC) and Piaçaguera Channel (PIC).

Fish responses to increasing distance from artificial reefs on the Southeastern Brazilian Coast

Journal of Experimental Marine Biology and Ecology, 2010
Abstract Artificial reefs have been deployed worldwide in shallow marine environments to enhance attraction and capture of fish, but, despite their potential as a fishery management option, few studies addressed whether fish assemblages will change with distance from a reef.

Chemical and pharmacological characterization of halitoxin from Amphimedon viridis (Porifera) from the southeastern Brazilian coast

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1996
The halitoxin complex from the marine sponge Amphimedon viridis, collected in the São Sebastião channel (southeastern Brazilian coast), was isolated by gel-filtration chromatography on Sephadex LH-20. Spectroscopic data (1H, 13C and 2D-NMR) of halitoxin from A.

PCB and PBDE levels in a highly threatened dolphin species from the Southeastern Brazilian coast

Environmental Pollution, 2016
In the Northern coast of Rio de Janeiro State is located the major urban centers of the oil and gas industry of Brazil. The intense urbanization in recent decades caused an increase in human use of the coastal areas, which is constantly impacted by agricultural, industrial and wastewater discharges.

Insights into leaded gasoline registered in mud depocenters derived from multivariate statistical tool: southeastern Brazilian coast

Environmental Geochemistry and Health, 2020
Lead has been widely used since antiquity, but its uses drastically increased during the Industrial Revolution. The global emission of Pb into the environment was mainly due to tetraethyl lead added to gasoline as an antiknock additive. Because of its toxicity and neurological effects, the compound was phased out in the 1980s.
