Intrashell oxygen and carbon stable isotope profiles (δ18O,δ13C) were established for Mesodesma donacium shells from the preceramic archaeological site, Quebrada de los Burros in coastal southern Peru, to reconstruct the sea-surface temperature (SST) variations and to estimate changes of the El Niño-Southem Oscillation (ENSO) interannual variability from the early Holocene to the present. Very strong oxygen isotopic excursions attributed to El Niño events are evident in three shells dated…

ENSO reconstructions over the past 60 ka using giant clams (Tridacna sp.) from Papua New Guinea

We present 12 seasonally resolved δ18O profiles of giant clams (Tridacna sp.) from the Huon Peninsula, Papua New Guinea, spanning discrete periods of time (9–38 years) over the past 60 ka. The

Modes of eastern equatorial Pacific thermocline variability: Implications for ENSO dynamics over the last glacial period

[1] Changes in El Nino–Southern Oscillation (ENSO) variability are difficult to extract from paleoceanographic reconstructions because they are superimposed on changes in seasonal variability that

Controls on δ18O and δ13C profiles within the aragonite bivalve Arctica islandica

The geochemistry of Arctica islandica shells provides an opportunity to reconstruct intra-annual resolution climate records in temperate latitudes, and the annual banding allows close temporal



Evidence for stronger El Niño-Southern Oscillation (ENSO) Events in a Mid-Holocene massive coral

We present a 47-year-long record of sea surface temperature (SST) derived from Sr/Ca and U/Ca analysis of a massive Porites coral which grew at ∼ 4150 calendar years before present (B.P.) in Vanuatu

Otolith δ18O Record of Mid-Holocene Sea Surface Temperatures in Peru

Peruvian sea catfish (Galeichthys peruvianus) sagittal otoliths preserve a record of modern and mid-Holocene sea surface temperatures (SSTs). Oxygen isotope profiles in otoliths excavated from Ostra

El Niño Variability in the Coastal Desert of Southern Peru during the Mid-Holocene

Fourteen organic-rich sedimentary layers in the deposits at Quebrada de los Burros, in coastal southern Peru (Tacna department), lie between two debris-flow units, interpreted to result from El Niño

Variability of El Niño/Southern Oscillation activity at millennial timescales during the Holocene epoch

A record of sedimentation in Laguna Pallcacocha, southern Ecuador, which is strongly influenced by ENSO variability, and covers the past 12,000 years continuously is presented, finding that changes on a timescale of 2–8 years become more frequent over the Holocene until about 1,200 years ago, and then decline towards the present.

Variation in Holocene El Niño frequencies: Climate records and cultural consequences in ancient Peru

Analysis of mollusks from archaeological sites on the north and central coasts of Peru indicates that between ca. 5800 and 3200–2800 cal yr B.P., El Nino events were less frequent than today, with

Suppression of El Niño during the Mid‐Holocene by changes in the Earth's orbit

A number of recent reports have interpreted paleoproxy data to describe the state of the tropical Pacific, especially changes in the behavior of the El Nino-Southern Oscillation (ENSO), over the

Holocene history of the El Niño phenomenon as recorded in flood sediments of northern coastal Peru

Significant precipitation along the north-central coast of Peru (lat 5°-10°S) occurs exclusively during El Nino incursions of warm water into the Peruvian littoral. Flood deposits from this region

Upwelling and productivity changes inferred from a temperature record in the central equatorial Pacific

A SERIES of C37–39 alkenones synthesized by prymnesiophyte algae is commonly preserved in marine sediments, and can be used for estimating past sea surface temperatures (SSTs)1,2. Here we present an
