On eddy polarity distribution in the southwestern Atlantic [PDF]

Deep-Sea Research Part I: Oceanographic Research Papers, 2012
Abstract Eddies in the southwestern Atlantic were detected from more than 18 years of satellite altimetry data using a modified version of the Okubo–Weiss method. The spatial distribution and polarity of eddies were examined. A larger concentration of cyclonic (anticyclonic) eddies was found on the left (right) side when looking downstream on some of

The flourishing and vulnerabilities of zoantharians on Southwestern Atlantic reefs

Marine Environmental Research, 2022
In the Southwestern Atlantic reefs (SWA), some species of massive scleractinians and zoantharians are adapted to turbid waters, periodic desiccation, and sediment resuspension events. Moreover, phase shifts in this region have mostly been characterized by the emergence of algae and, less typically, zoantharians.

Seasonal variability in the southwestern Atlantic

Journal of Geophysical Research: Oceans, 1993
The circulation of the southwestern Atlantic Ocean is dominated by the Subtropical Gyre and the confluence of the Brazil and Malvinas currents. Observations indicate that the latitude of this confluence changes seasonally, lying farther north during the austral winter than during the summer.

On the Characteristics and Circulation of the Southwestern Atlantic Ocean

Journal of Physical Oceanography, 1977
Abstract The waters found within the southwestern Atlantic Ocean extend into it as separate lavers with markedly different characteristics. Along the western boundary the deeper waters, derived from the North Atlantic, are warm, highly saline, oxygen-rich and nutrient-poor.

The Holocene onset in the southwestern South Atlantic

Palaeogeography, Palaeoclimatology, Palaeoecology, 2013
Abstract In this paper we present a paleoceanographic reconstruction of the southwestern South Atlantic for the past 13 kyr based on faunal and isotopic analysis of planktonic foraminifera from a high-resolution core retrieved at the South Brazil Bight continental slope.

Indirect wind observations in the southwestern Atlantic

Journal of Geophysical Research: Oceans, 1986
Two time series of wind speed have been inferred from ambient noise measurements obtained with bottom‐deployed inverted echo sounders in the southwestern Atlantic. Comparison between inferred winds and winds from the National Meteorological Center Tropical Strip Surface Analysis product establishes that there is a good agreement between the two ...

Biogeography of the Quaternary Molluscs of the Southwestern Atlantic Ocean

2013
The Quaternary comprises a brief time in the Earth’s history, and apart from a few exceptions, molluscan assemblages recovered from exposures along the coast of Southwestern South America (Southern Brazil, Uruguay, Argentina) are essentially the same than those that inhabit the region today, leading to the assumption that no important change in the ...

Deep-Sea Microbes in the Southwestern Atlantic

2020
Microbes possess a great genetic repertoire and metabolic versatility that allow them to face the extreme conditions of the deep sea, drive the biogeochemical cycles, and feed chemosynthetic web chains. These microbes respond to historical, global, regional, and local processes in deep-sea habitats and are influenced by microenvironmental variations ...

Overview on Primary Production in the Southwestern Atlantic

2018
Photosynthesis is the fundamental process by which autotrophs produce organic matter to sustain the biosphere using basic elements (i.e., CO2 and H2O) and solar irradiance as energy source. Marine phytoplankton provides near half of the global primary production (PP), being at the base of most marine trophic webs and playing an important role in the ...
