A new Permian bivalve-dominated assemblage in the Rio do Rasto Formation, Parana Basin, Brazil: Faunal turnover driven by regional-scale environmental changes in a vast epeiric sea
(Elsevier B.V., 2015-12-01)
The basal portion of the Permian Rio do Rasto Formation (Serrinha Member), Passa Dois Group, Parana Basin, Brazil, records an entirely new bivalve fauna intercalated between the underlying Pinzonella neotropica assemblage ...
Increased rainfall remarkably freshens estuarine and coastal waters on the Pacific coast of Panama: Magnitude and likely effects on upwelling and nutrient supply.
(Elsevier Science, 2012-07)
Increased intensity of rainfall events during late 2010 led to a remarkable freshening of estuarine, near- and off-shore waters in coastal Pacific Panama. The increased rain intensity during the wet season of 2010 lowered ...
Did North Atlantic cooling and freshening from 3.65–3.5 Ma precondition Northern Hemisphere ice sheet growth?
(Elsevier, 2020)
The North Atlantic Current (NAC) as part of the Atlantic Meridional Overturning Circulation (AMOC) is the major supplier of heat into the northern North Atlantic. Pliocene changes of AMOC strength were speculated to either ...
The impacts of deglacial meltwater forcing on the South Atlantic Ocean deep circulation since the Last Glacial Maximum
(2014-09-17)
A NCAR-CCSM3 (National Center for Atmo- spheric Research – Community Climate System Model ver- sion 3) state of-the-art transient paleoclimate simulation with prescribed freshwater inflows is used to investigate the changes ...
Marine or freshwater? Accessing the paleoenvironmental parameters of the Caldas Bed, a key marker bed in the Crato Formation (Araripe Basin, NE Brazil)
(Sociedade Brasileira de Geologia, 2020-12-21)
The Aptian Crato Formation is world renowned for its well-preserved fossils in microbially-induced laminated limestones, which are regarded as one of the main Cretaceous Konservat-Lagerstätte of the geological record. ...
Global deglaciation and the re-appearance of microbial matground-dominated ecosystems in the late Paleozoic of Gondwana
(Wiley, 2013-07)
The extensive matgrounds in Carboniferous-Permian open-marine deposits of western Argentina constitute an anachronistic facies, because with the onset of penetrative bioturbation during the early Paleozoic microbial mats ...
Late Holocene hydrology inferred from lacustrine sediments of Laguna Cháltel (southeastern Argentina)
(Elsevier Science, 2014-07)
Hydrological changes that occurred during the last 4700 years have been reconstructed using multi-proxy analyses of sediment cores from the volcanic crater lake of Laguna Cháltel (50°S, 71°W). The chronology is based on ...
Assessing the effect of sea-level change and human activities on a major delta on the Pacific coast of northern South America: The Patía River
(ELSEVIER SCIENCE BV, 2012-05-15)
This paper presents the main physical and human-induced stresses that have shaped the recent evolution of the Patía River delta, the largest and best-developed delta on the western margin of South America. During the ...
Human induced discharge diversion in a tropical delta and its environmental implications: The Patía River, Colombia
(ELSEVIER SCIENCE BV, 2012-03-06)
The Patía River, the number one in terms of sediment yield ~1500tkm -2yr -1 draining the western South America, has the most extensive and well developed delta on the Pacific coast, measuring 1700km 2. During the Holocene, ...
On the temporal variability of intermediate and deep waters in the Western Basin of the Bransfield Strait
(Pergamon-Elsevier Science Ltd, 2018-03)
The Western Basin (WB) of the Bransfield Strait has a complex water mass structure derived from a variety of sources, and is located next to the Antarctic region most affected by climate change. The WB is one of the three ...
