TL;DR: This is the first set of consistently dated marine sediment cores enabling paleoclimate scientists to evaluate leads/lags between circulation and climate changes over vast regions of the Atlantic Ocean.
Journal ArticleDOI

TL;DR: In this paper, a high resolution marine sediment sequence over the last deglaciation was used to provide evidence for a synchronous and near-linear link between changes in the Atlantic interhemispheric sea surface temperature difference and continental precipitation over northeast Brazil.
Journal ArticleDOI
Different precipitation patterns across tropical South America during Heinrich and Dansgaard-Oeschger stadials
Yancheng Zhang,Cristiano Mazur Chiessi,Stefan Mulitza,André Oliveira Sawakuchi,Christoph Häggi,Matthias Zabel,Rodrigo Costa Portilho-Ramos,Enno Schefuß,Stefano Crivellari,Gerold Wefer +9 more
TL;DR: In this paper, the influence of tropical South American precipitation patterns during Heinrich (H) and Dansgaard-Oeschger (DO) stadials on both inorganic (Fe/Ca record) and organic (C37/C38 ratio) geochemistry was investigated.
Journal ArticleDOI
The Fate of Cold-Water Corals in a Changing World: A Geological Perspective
TL;DR: In this article, a geological approach is presented that by correlating geological CWC records with paleoceanographic data describing past environmental changes allows to identify a set of key environmental drivers that directly or indirectly control CWC vitality.
Journal ArticleDOI
Methane release from the southern Brazilian margin during the last glacial.

TL;DR: The results show that shallow gas deposits on the southern Brazilian margin responded to glacial−interglacial paleoceanographic changes releasing methane due to the synergy of sea level lowstand, warmer bottom waters and vigorous bottom currents during the last glacial period.
