In the present-day climate, surface water salinities are low in the western tropical Pacific Ocean and increase towards the eastern part of the basin. The salinity of surface waters in the tropical Pacific Ocean is thought to be controlled by a combination of atmospheric convection, precipitation, evaporation and ocean dynamics, and on interannual timescales significant variability is associated with the El Niño/Southern Oscillation cycles. However, little is known about the variability of the… 
Unprecedented recent warming of surface temperatures in the eastern tropical Pacific Ocean
Climate variability in the tropical Pacific Ocean influences climate across much of the planet. A diatom-based record of sea surface temperatures from El Junco lake, Galapagos, reveals that the most
Holocene evolution of the Indonesian throughflow and the western Pacific warm pool
High sea surface temperatures in the western Pacific warm pool fuel atmospheric convection and influence tropical climate. This region also hosts the Indonesian throughflow, the network of currents
Holocene tropical western Indian Ocean sea surface temperatures in covariation with climatic changes in the Indonesian region
The sea surface temperature (SST) of the tropical Indian Ocean is a major component of global climate teleconnections. While the Holocene SST history is documented for regions affected by the Indian
Seawater isotope constraints on tropical hydrology during the Holocene
Paleoceanographic data from the low latitude Pacific Ocean provides evidence of changes in the freshwater budget and redistribution of freshwater within the basin during the Holocene. Reconstructed
Holocene Southern Ocean surface temperature variability west of the Antarctic Peninsula
It is concluded that during the Holocene, Southern Ocean temperatures at the western Antarctic Peninsula margin were tied to changes in the position of the westerlies, which have a critical role in global carbon cycling.
Holocene surface hydroclimate changes in the Indo-Pacific warm pool
Millennial-scale trends in west Pacific warm pool hydrology since the Last Glacial Maximum
The results suggest that convection over the western tropical Pacific weakened 18,000–20,000 years ago, as tropical Pacific and Antarctic temperatures began to rise during the early stages of deglaciation, and that the tropical Pacific hydrological cycle may have a central role in abrupt climate change events.


Climate impact of late quaternary equatorial pacific sea surface temperature variations
Comparison of SST estimates from eastern and western sites indicates that the equatorial Pacific zonal SST gradient was similar or somewhat larger during glacial episodes, and extraction of a salinity proxy from the magnesium/calcium and oxygen isotope data indicates that transport of water vapor into the western Pacific was enhanced duringglacial episodes.
Orbital and suborbital climate variability in the Sulu Sea, western tropical Pacific
A detailed record of planktic δ18O from a sediment core in the Sulu Sea, located between the South China Sea and the western Pacific warm pool, reveals that for the past 400 kyr (1 kyr = 1000 years),
Upper ocean salinity balance in the western equatorial
The upper ocean salinity balance in the western equatorial Pacific warm pool was evaluated using up to 2.5 years of data (September 1991 through April 1994) from the Coupled Ocean-Atmosphere Response
Temperature and surface-ocean water balance of the mid-holocene tropical western pacific
The results suggest that the temperature increase enhanced the evaporative enrichment of 18O in seawater, and transport of part of the additional atmospheric water vapor to extratropical latitudes may have sustained the 18O/16O anomaly.
Salinity records for the 1997–98 El Niño from Western Pacific corals
Seasonal sea surface salinity (SSS) records can be of great value in reconstructing El Niño/Southern Oscillation (ENSO) variability in the equatorial Western and Central Pacific, a region where
Sea-level and deep water temperature changes derived from benthic foraminifera isotopic records
We show that robust regressions can be established between relative sea-level (RSL) data and benthic foraminifera oxygen isotopic ratios from the North Atlantic and Equatorial Pacific Ocean over the
Southward Migration of the Intertropical Convergence Zone Through the Holocene
The Cariaco Basin record exhibits strong correlations with climate records from distant regions, including the high-latitude Northern Hemisphere, providing evidence for global teleconnections among regional climates.
Orbital controls on the El Niño/Southern Oscillation and the tropical climate
The global synchroneity of glacial-interglacial events is one of the major problems in understanding the link between Milankovitch forcing and the climate of the late Quaternary. In this study we
Enhanced Atlantic freshwater export during El Niño
Using two reanalysis data sets, the influence of El Niño/Southern Oscillation (ENSO) on the surface freshwater balance of the Atlantic ocean is examined. We present evidence that the transport of
Coherent high- and low-latitude climate variability during the holocene warm period
A faunal record of sea-surface temperature (SST) variations off West Africa documents a series of abrupt, millennial-scale cooling events, which punctuated the Holocene warm period, documenting a strong, in-phase link between millennial- scale variations in high- and low-latitude climate during the Hololithic.
