TL;DR: In this paper, the authors used diatoms and radiolarians to reconstruct the last glacial environment at the EPILOG (19.5 −16.0 −1.0 ǫ) or 23 −000 −19 ǔcal yr.

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 article, the authors present a new multiproxy data set of sea surface temperatures (SST), dust and iron supply, and marine export productivity from the marine sediment core PS2489-2/ODP Site 1090 located in the subantarctic Atlantic, that allow them to evaluate various hypotheses on the role of the Southern Ocean (SO) in modulating atmospheric CO2 concentrations back to 11 Ma.

TL;DR: A study of 230 surface sediment samples collected in the Atlantic sector of the Southern Ocean between the southernmost Weddell Sea and the Subtropical Zone documents the modern distribution of diatoms revealing patterns of paleoenvironmental significance as discussed by the authors.

TL;DR: In this paper, the authors used time-series sediment traps combined with the mapping of diatom assemblages from surface sediments to define a proxy for past variations of sea-ice extent.
