Cleaning efficiency in a Southwestern Atlantic sandy beach

Regional Studies in Marine Science, 2021
Abstract Although the assessment of beach cleaning efficiency evaluation would be desirable for management purposes, the practice is not common. This evaluation is crucial for the safety of beachgoers, conservation efforts aiming to preserve ecological services, and the sustainable development of the oceans.

An Overview of the Medusozoa from the Southwestern Atlantic

2018
Medusozoans are critical components of coastal and marine ecosystems. They are ubiquitous, living from the surface to the bottom layers of the world’s oceans and tolerating a wide range of environmental conditions. They modulate food webs not only by consuming large quantities of ichthyoplankton and other zooplankton and acting as predators and ...

Polychaete distribution on the southwestern Atlantic continental shelf

Marine Biology Research, 2016
ABSTRACTDiversity and distribution of polychaetes on the southeastern Brazilian Shelf (SBS) adjacent to the city of Santos were studied. The study area is situated in the vicinity of Santos Bay with its estuarine complex and other small rivers along the coast.

BOTTOM SEDIMENTS AND NEAR-BOTTOM CURRENTS IN THE SOUTHWESTERN ATLANTIC

Геология и геофизика, 2015
Abstract On the basis of the author’s data on the composition of sediments and seismic cross sections, together with literature data, the bottom topography was described and the main structural features of the top 10–100 m thick sedimentary sequence in the Southwestern Atlantic (Brazil Basin) were identified.

Diversity and distribution of the mesozooplankton in the tropical Southwestern Atlantic

Journal of Plankton Research, 2008
Mesozooplankton species distribution and abundance were studied in the tropical Southwestern Atlantic, in neritic and oceanic regions off the state of Rio Grande do Norte, northeastern Brazil (3° to 6° S and 32°30' to 35°30' W). Samples were collected with a 120 μm mesh net towed horizontally at 40 stations along five transects in June 1986. A total of

Ichthyoplankton Associated to the Frontal Regions of the Southwestern Atlantic

2018
The study region covers a wide latitudinal range, from 22°S to 55°S, and a bathymetric scope ranging from the coast to the shelf-break and adjacent region to a depth of ca. 1000 m. Hydrography of the region is extremely complex. Oceanographic structures are diverse, including several estuaries, water masses, wind systems, tidal regimes, and two major ...

Acoustic habitat of an oceanic archipelago in the Southwestern Atlantic

Deep Sea Research Part I: Oceanographic Research Papers, 2016
Abstract Underwater soundscapes can be highly variable, and in natural conditions are often dominated by biological signals and physical features of the environment. Few studies, however, focused on oceanic islands soundscapes. Islands in the middle of ocean basins can provide a good example of how untouched marine soundscapes are.

Circulation of bottom waters in the southwestern South Atlantic

Deep Sea Research Part A. Oceanographic Research Papers, 1981
Data from 137 new hydrographic stations are used with older hydrographic data to construct horizontal charts of potential temperature at 4000 m and the depth of the 0°C potential temperature surface for the southwestern South Atlantic. The data are also used to construct seven potentials temperature sections and to calculate bottom water transport ...

Alien Decapod Crustaceans in the Southwestern Atlantic Ocean

2011
Thirteen marine alien species of decapod crustaceans have been recorded from the Southwestern Atlantic. Five species of alien decapods have established local populations: Charybdis hellerii (Brazil), Eurypanopeus depressus (Uruguay and Argentina), Palaemon macrodactylus (Argentina), Pyromaia tuberculata (Brazil and Argentina) and Rhithropanopeus ...
