Tropical South America is one of the three main centres of the global, zonal overturning circulation of the equatorial atmosphere (generally termed the ‘Walker’ circulation). Although this area plays a key role in global climate cycles, little is known about South American climate history. Here we describe sediment cores and down-hole logging results of deep drilling in the Salar de Uyuni, on the Bolivian Altiplano, located in the tropical Andes. We demonstrate that during the past 50,000 years… 

Past Climate Variability in South America and Surrounding Regions

Paleorainfall variability on orbital and millennial time scales is discussed for the last glacial period and the Holocene, based on a multi-proxy study of speleothem records from Brazil. Oxygen

Wet periods in northeastern Brazil over the past 210 kyr linked to distant climate anomalies

A 210,000-year record of wet periods in tropical northeastern Brazil is presented, finding wet periods that are synchronous with periods of weak East Asian summer monsoons, cold periods in Greenland, Heinrich events in the North Atlantic and periods of decreased river runoff to the Cariaco basin.

Abstract : This thesis evaluates the variability of two tropical climate phenomena over the past 20,000 years. The first phenomenon is the migration of the Intertropical Convergence Zone (lTCZ)

Holocene multidecadal- to millennial-scale hydrologic variability on the South American Altiplano

Precipitation on the South American Altiplano varies at a range of temporal scales. A long-term secular increase in moisture availability from the early/mid Holocene to the present, driven by

Hydrologic variation during the last 170,000 years in the southern hemisphere tropics of South America

Hydroclimate variability in the low-elevation Atacama Desert over the last 2500 yr

Paleoclimate reconstructions reveal that Earth system has experienced sub-millennial scale climate changes over the past two millennia in response to internal/external forcing. Although

Orbital and Millennial-Scale Precipitation Changes in Brazil from Speleothem Records

Paleorainfall variability on orbital and millennial time scales is discussed for the last glacial period and the Holocene, based on a multi-proxy study of speleothem records from Brazil. Oxygen

Eastern tropical Pacific hydrologic changes during the past 27,000 years from D/H ratios in alkenones

[1] The tropical Pacific plays a central role in the climate system by providing large diabatic heating that drives the global atmospheric circulation. Quantifying the role of the tropics in late

Quaternary glaciation and hydrologic variation in the South American tropics as reconstructed from the Lake Titicaca drilling project




Warming of the tropical Atlantic Ocean and slowdown of thermohaline circulation during the last deglaciation

Evidence for abrupt climate changes on millennial and shorter timescales is widespread in marine and terrestrial climate records. Rapid reorganization of ocean circulation is considered to exert some

A 25,000-year tropical climate history from bolivian ice cores

The abrupt onset and termination of a Younger Dryas-type event suggest atmospheric processes as the probable drivers of regional accumulation during the LGS, during deglaciation, and over the past 3000 years, which is concurrent with higher water levels in regional paleolakes.

Molecular stratigraphy of cores off northwest Africa: Sea surface temperature history over the last 80 Ka

The molecular stratigraphy of Biogeochemical Oceanic Flux Study core 31K (19°N, 20°10′W) and Ocean Drilling Program Hole 658C (20°45′N, 18°35′W;) has been studied for C37 alkenone abundances over the

Reassessment of ice-age cooling of the tropical ocean and atmosphere

The CLIMAP project's reconstruction of past sea surface temperature inferred limited ice-age cooling in the tropical oceans. This conclusion has been controversial, however, because of the greater

Constraints on the Origin of Paleolake Expansions in the Central Andes

Abstract During the late Pleistocene, at least one episode of lake expansions occurred in the internally draining high plateau region of Bolivia. Some researchers have advocated that a wetter climate

Foraminiferal faunal estimates of paleotemperature: Circumventing the No‐analog problem yields cool Ice Age tropics

The sensitivity of the tropics to climate change, particularly the amplitude of glacial-to-interglacial changes in sea surface temperature (SST), is one of the great controversies in

Lake-Level Chronology on the Southern Bolivian Altiplano (18°–23°S) During Late-Glacial Time and the Early Holocene

Abstract Stratigraphic analyses of outcrops, shorelines, and diatoms from the southern Bolivian Altiplano (Uyuni-Coipasa basin) reveal two major lacustrine phases during the late-glacial period and

Does a Monsoon Climate Exist over South America

The climatology and the basic state of the summertime circulation and rainfall over South America are studied using assimilation products from the data assimilation system of Goddard Earth Observing

Climate and lake-level history of the northern Altiplano, Bolivia, as recorded in Holocene sediments of the Rio Desaguadero

ABSTRACT Strata exposed in terraces and modern cutbanks along the Rio Desaguadero contain a variety of lithofacies that were deposited in four distinct facies associations. These facies associations
