Scopoli’s shearwater, Calonectris diomedea, in the southwest Atlantic Ocean

Marine Biodiversity, 2017
Knowledge of marine biodiversity has been increased by combining modern and traditional tools that render species identification an accurate process. In addition, understanding the ecological differences between closely related species is critical for effective conservation.

Bacterial Abundance and Production in the Southwest Atlantic Ocean

Hydrobiologia, 2004
A bacterial dynamics study was conducted in the southwest Atlantic Ocean off the Brazilian coast from October to December 1998 with samples collected at the depth of chlorophyll a maximum. The bacteria were counted by flow cytometry with the SYTO13 DNA dye and bacterial activity was measured as carbon production by the uptake of 3H-leucine. The samples

Variations of the mean sea level in the southwest Atlantic Ocean

Continental Shelf Research, 1988
Abstract The lack of information on the variation of sea level in the southern hemisphere hinders its estimation. It is for this reason that in this paper an analysis of 64 years of hourly tide heights at the most trustworthy Argentina oceanic station has been made, using a symmetric low-pass filter based on the Kaiser-Bessel window, which permits ...

The evolution of the Rio Grande Rise in the southwest Atlantic Ocean

Marine Geology, 1984
Abstract The Rio Grande Rise, a major aseismic rise in the western South Atlantic Ocean, is composed of two portions with distinct morphologies and geological histories. The western portion of the Rise (WRGR) is a large elliptical bulge with its crest at a mean depth of about 2000 m. Numerous guyots protrude from its main platform.

Clymene dolphin (Stenella clymene) whistles in the Southwest Atlantic Ocean

The Journal of the Acoustical Society of America, 2018
The Clymene dolphin despite being endemic for the Atlantic Ocean continues to be the least known species in the genus Stenella without available information on their vocal repertoire in Brazilian waters. Data were obtained during mitigation and monitoring work required by IBAMA under the federal environmental licensing as conditions of the license 108 ...

Marine debris ingestion by the South American Fur Seal from the Southwest Atlantic Ocean

Marine Pollution Bulletin, 2017
In this paper, we examined the ingestion of marine debris (MD) in South American fur seals (SAFS), Arctocephalus australis, found dead in coastal beaches of northern Argentina and southern Brazil. Seven percent of 133 SAFS analyzed presented marine debris in their stomach (n=10), with no differences between sampling countries (Brazil n=7, Argentina n=3)

Post-Miocene fluctuations of Antarctic Bottom Water paleospeed in the southwest Atlantic Ocean

Deep Sea Research Part II: Topical Studies in Oceanography, 1993
Abstract A gap in the Falkland Escarpment serves as the primary channel through which Antarctic Bottom Water (AABW) flows into the Argentine Basin from the Georgia Basin. The particle-size distributions of the biogenic-free silt fraction in four cores near the Falkland Gap and the hiatus frequency at water depths greater than 4000 m throughout the ...
