Editorial: Wet and dry periods in regions surrounding the Atlantic Ocean Basin
(Frontiers Research Foundation, 2016-02)
The Atlantic Ocean is the second-largest of the world's oceanic divisions. It is bounded by the continents of America, Europe, and Africa and at its polewards margins by the Arctic and the Southern Oceans. Different climatic ...
Patagonian and southern South Atlantic view of Holocene climate
(Pergamon-Elsevier Science Ltd, 2016-04)
We present a comprehensive 10Be chronology for Holocene moraines in the Lago Argentino basin, on the east side of the South Patagonian Icefield. We focus on three different areas, where prior studies show ample glacier ...
From a Shapiro-Keyser extratropical cyclone to the subtropical cyclone Raoni: An unusual winter synoptic situation over the South Atlantic Ocean
(Wiley-Blackwell, 2022-07-01)
The eastern coast of South America is a cyclogenetic region in terms of extratropical cyclones and, in lower number, of subtropical cyclones that are more frequent in austral summer and autumn. However, in June 2021, an ...
Ogmogaster antarctica (Digenea: Notocotylidae) infecting a dwarf minke whale Balaenoptera acutorostrata (Cetartiodactyla: Balaenopteridae) from the southwestern Atlantic Ocean
(Springer, 2020-02-24)
Digeneans of the genus Ogmogaster Jagerskiold, 1891 are intestinal parasites of whales and pinnipeds. Due to the difficulty in recovering these parasites from opportunistic stranding events of their hosts, very little ...
Estimating the geographic range of a threatened shark in a data-poor region: Cetorhinus maximus in the South Atlantic Ocean
(Oxford University Press, 2015-10)
The distribution of the planktivorous basking shark Cetorhinus maximus is influenced by zooplankton abundance at small scales and temperature at medium scales in the North Atlantic. Here, we estimate the distribution of ...
Reproductive biology of the southern thorny skate Amblyraja doellojuradoi (Chondrichthyes, Rajidae)
(Wiley Blackwell Publishing, Inc, 2016-04)
The total lengths (LT) of 193 males (209-556mm) and 130 females (275-515mm) of Amblyraja doellojuradoi, a commercial by-catch species on the Argentinean continental shelf, which are increasingly retained, were analysed. ...
The potential of Glycymeris longior (Mollusca, Bivalvia) as a multi-decadal sclerochronological archive for the Argentine Sea (Southern Hemisphere)
(Elsevier, 2020-03)
In the absence of instrumental records, shell growth increments of bivalves are used to build continuous multi-decadal time series of growth and to estimate environmental variability. While there is interest in such ...
Mesoscale distribution and population structure of the chaetognath Serratosagitta tasmanica (Thomson, 1947) from Southwestern Atlantic Ocean
(Taylor & Francis, 2018-11)
Although Serratosagitta tasmanica is widely distributed, there is little information on how hydrology affects its distribution, abundance and demography. In this study we analyzed the distribution, carbon content and ...
Geometry and structure of the pull-apart basins developed along the western South American-Scotia plate boundary (SW Atlantic Ocean)
(Pergamon-Elsevier Science Ltd, 2018-04)
The South American-Scotia plate boundary is a left-lateral fault system which runs roughly E-Wfor m o reth an 3000 km across the SW Atlantic Ocean and the Tierra del Fuego Island, reaching to the west thesouthern Chile ...
