TL;DR: This article presented an updated synthesis of sea surface temperatures during the Last Glacial Maximum, rigorously defined as the period between 23 and 19 thousand years before present, from the Multiproxy Approach for the Reconstruction of the Glacial Ocean Surface (MARGO) project.

TL;DR: In this paper, a multi-proxy approach and a strategy combining lacustrine and marine records along a north-south transect were used to reconstruct high-resolution and well-dated palaeohydrological records and to assess their spatial and temporal coherency.
Journal ArticleDOI
Glacial Mediterranean sea surface temperatures based on planktonic foraminiferal assemblages
TL;DR: In this paper, a new reconstruction of Mediterranean sea surface temperatures (SST) during the last glacial maximum (LGM) was presented, based on a calibration data set based on census counts of 23 species of planktonic foraminifera in 129 North Atlantic and 145 Mediterranean core top samples.

TL;DR: In this article, les carottes reparties dans les principaux bassins de cette mer montrent qu'a l'epoque de la formation du dernier sapropele (S 1 ) en Mediterranee orientale, and environnement 8 000 ans, les temperatures de surface etaient environ 1,5 a 2,5 °C plus froides qu'aujourd'hui dans le bassin occidental alors qu'en Mediterrano Orientale, elles et
