Reconstructed temperature and tephra deposit age data from Yanou Lake, Fildes Peninsula, South Shetland Islands, northern Antarctic Peninsula

The dataset comprises reconstructed temperature and tephra deposits age data from Yanou Lake, Fildes Peninsula, King George Island, South Shetland Islands. Data are calibrated to the 2020 radiocarbon calibration curves. The Antarctic and global glycerol dialkyl glycerol tetraether (GDGT) lipid biomarker temperature calibration are included. GDGT MSAT (mean summer air temperature) data was obtained by recalibrating the Pearson et al. (2011) global and Foster et al. (2016) Antarctic lake surface GDGT MSAT datasets. This dataset includes updates with new calibration of data originally published in Roberts et al. (2017).

These revisions were funded as part of the IMCONet (FP7 IRSES, action no. 318718) program led by Doris Abele (AWI); the Natural Environment Research Council (NERC/BAS-CGS Grant no.81); the NERC/BAS science programmes CACHE-PEP: Natural climate variability - extending the Americas palaeoclimate transect through the Antarctic Peninsula to the pole and GRADES-QWAD: Quaternary West Antarctic Deglaciations.
