Diatom-based sea-surface temperatures over the last 40 kyrs in core MD12-3396CQ northeast of Kerguelen Island, Southern Ocean
Diatom census counts were used to quantitatively estimate summer sea-surface temperatures (SST) over the last 40,000 years in core MD12-3396CQ, collected in 2012 on board the R.V. Marion Dusfresne northeast of Kerguelen Island, Southern Ocean. The transfer function used to reconstruct summer (Januna...
