Map showing the location of over 400 lake sediment samples used in this new study
A map of the world showing the locations of over 400 lakes whose surface sediments were analysed for biomarker compounds called branched glycerol dialkyl glycerol tetraethers (brGDGTs) are a group of temperature-sensitive membrane lipids found in bacteria that have been widely used in palaeo-temperature reconstruction. The paper expands existing calibration datasets, and evaluates calibration models constructed using a range of statistical modelling approaches
