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.
Distribution of recent dinoflagellate cysts in surface sediments from the North Atlantic Ocean and adjacent seas in relation to sea-surface parameters
TL;DR: Validation procedures on this transfer function demonstrate that more than 95% of the reconstructions are included within the interannual variability of modern sea-surface conditions, and can be applied to reconstructing paleotemperatures and salinities from analogous assemblages in Quaternary sedimentary sequences.
Journal ArticleDOI
Reconstruction of sea-surface conditions at middle to high latitudes of the Northern Hemisphere during the Last Glacial Maximum (LGM) based on dinoflagellate cyst assemblages
A. de Vernal,Frédérique Eynaud,Maryse Henry,Claude Hillaire-Marcel,Laurent Londeix,Sylvie Mangin,Jens Matthiessen,Fabienne Marret,Taoufik Radi,André Rochon,Sandrine Solignac,Jean-Louis Turon +11 more
TL;DR: A database of census counts of organic-walled dinoflagellate cyst (dinocyst) assemblages has been developed from the analyses of surface sediment samples collected at middle to high latitudes of the Northern Hemisphere after standardisation of taxonomy and laboratory procedures as discussed by the authors.
Journal ArticleDOI
Absence of deep-water formation in the Labrador Sea during the last interglacial period
TL;DR: The results indicate that today's stratification between Labrador Sea Water and North Atlantic Deep Water never developed during the last interglacial period, and the present situation, with an active site of intermediate-water formation in the Labrador Sea, has no analogue throughout the last climate cycle.
Journal ArticleDOI
Isotope stratigraphy, sedimentation rates, deep circulation, and carbonate events in the Labrador Sea during the last ~ 200 ka
TL;DR: In this article, stable isotope and accelerator mass spectrometry 14C measurements in 25 box and piston cores from the Labrador Sea allow the reconstruction of major paleoceanographical changes during the last ~ 200 000 years in this basin and also document the links between the interior of the Laurentide Ice Sheet and the North Atlantic Ocean during this interval.
