Middle to Late Miocene paleoceanographic evolution of the south-eastern Indian Ocean 1 (

Deep-water hydrographic variability in the Northeast Atlantic during MIS 4

Intertropical convergence zone and El Niño Southern oscillation controls on late Holocene rainfall variability in Palau

The Tropical West Pacific is an understudied region in environmental and archaeological studies when compared to continental regions. The unique geologies, climate systems, and ecological dynamics in the Tropical West Pacific greatly limit the transferrability of palaeoenvironmental proxies established from studies out...

Impact of the Tibetan Plateau and Rocky Mountains on deep ocean circulation during the Middle Miocene

Persistent influence of the North Atlantic Oscillation on Late Holocene hydroclimate in southwestern Greenland

Understanding how global climate forcing shapes regional hydroclimate on decadal to millennial timescales is critical for predicting the response of continental ice sheets to future warming. Because instrumental observations capture only a short interval, longer-term perspectives require proxy records. Here we present...

Recent strengthening of eastern Pacific ENSO in the last millennium paleorecord.

The Pacific El Niño-Southern Oscillation (ENSO) generates climate extremes that endanger ecosystems, infrastructure, and human well-being worldwide. The response of this system to climate warming is poorly constrained, due both to data scarcity and uncertainties in climate models. The geochemistry of Galápagos coral sk...

Coupling of Pacific and Indian Ocean variability disrupted by 19th century volcanism

Through tropical basin interactions, the Indian Ocean Walker circulation (IWC) and basin mode (IOBM) covary with the Pacific Walker circulation (PWC) on interannual-decadal timescales. Coupling between IOBM and PWC has degraded considerably in recent decades due to greenhouse gas forcing; however, the instrumental reco...
