The Role of Lightning in Atmospheric Chemistry
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

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, 2022In 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, 1993The 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.

An Overview of the Medusozoa from the Southwestern Atlantic
2018Medusozoans 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 ...

On the Characteristics and Circulation of the Southwestern Atlantic Ocean
Journal of Physical Oceanography, 1977Abstract 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, 2013Abstract 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.

Overview on Primary Production in the Southwestern Atlantic
2018Photosynthesis 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 ...

Indirect wind observations in the southwestern Atlantic
Journal of Geophysical Research: Oceans, 1986Two 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
2013The 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 ...
