Analysis of south hemisphere temperature anomalies over the last millennium up to the beginning of the contemporary age: a comparison between a statistical model and a global dynamic model
(Scientific Research, 2014-06)
We analyze the consistency of the coupled atmosphere-ocean GISS-ER climate model in reproducing South American temperature anomalies over the last millennium. For that purpose, we compare the model results with the Neukom’s ...
Finding the expression of MCA and LIA along a sediment core from northern Patagonia using fatty acids from leaf waxes
(2018)
The Patagonia is of interest on climatic studies because is directly influenced the entire year by westerly winds from 40° S to 55° S. During the last 1000 years
there are two climatic anomalies described in Patagonia, the ...
Last millennial environmental reconstruction based on a multi-proxy record from Laguna Nassau, Western Pampas, Argentina
(E Schweizerbartsche Verlags, 2015-08)
We present a multi-proxy record from Laguna Nassau (LN), a shallow lake which developed in a blowout depression in the semi-arid sandy lowlands of the Western Pampas of Argentina. This multi-proxy stacked record reveals ...
Interactions between fluvial dynamics and scarp retreat in the Central Ebro Basin during MCA and LIA periods: Palaeogeographical and geoarchaeological reconstruction
(Elsevier Science, 2021-04)
The scarp of Remolinos-Juslibol is an abrupt relief formed by Miocene gypsums located on the left bank of the Ebro River, in the vicinity of the city of Zaragoza. This work provides data for the reconstruction of the channel ...
Southern Hemispheric Westerlies control sedimentary processes of Laguna Azul (south-eastern Patagonia, Argentina)
(Sage Publications Ltd, 2019-03)
Multiproxy investigations of lacustrine sediments from Laguna Azul (52 °S) document multi-millennial Holocene influences of Southern Hemispheric Westerlies (SHW) on the hydroclimatic variability of south-eastern Patagonia. ...
A late Holocene paleoclimate reconstruction from Boqueirão Lake sediments, northeastern Brazil
(Brasil, 2014)
Lake level fluctuations and environmental changes during the late Holocene were inferred from changes in sedimentology, bulk and isotope organic geochemistry, and a diatom based transfer function in a sediment core from ...
Hydroclimate variability of the northwestern Amazon Basin near the Andean foothills of Peru related to the South American Monsoon System during the last 1600 years
(European Geosciences Union (EGU), 2014-11-19)
In this paper we explore a speleothem δ ¹⁸O record from Palestina cave, northwestern Peru, at a site on the eastern side of the Andes cordillera, in the upper Amazon Basin. The δ ¹⁸O record is interpreted as a proxy for ...
Precipitation changes over the eastern Bolivian Andes inferred from speleothem (δ¹⁸O) records for the last 1400 years
(Elsevier, 2018-07-15)
Here we present high-resolution δ¹⁸ records obtained from speleothems collected in the eastern Bolivian Andes. The stable isotope records are related to the regional- to large-scale atmospheric circulation over South America ...
Speleothem records decadal to multidecadal hydroclimate variations in southwestern Morocco during the last millennium
(Elsevier, 2017-10-15)
This study presents the first well-dated high resolution stable isotope (δ¹⁸O and δ¹³C) and trace element (Mg and Sr) speleothem records from southwestern Morocco covering the last 1000 yrs. Our records reveal substantial ...
