Descriptions

The dataset comprises of GPS site data, bathymetric data from Lago Pato, a small lake basin at 51.3003 S, 72.6786 W and approx 33 m a.s.l., water chemistry collected from lakes in the region made in 2007 and precipitation data generated from the ERA-INTERIM model for Lago Pato. The data are used to help constrain glacier dynamics and lake level change in the TdP and Ultima Esperanza region over the last approx 30,000 cal a BP (30 ka). This project was funded by the Natural Environment Research Council (NERC) through the British Antarctic Survey (BAS) and an UGent BOF bilateral collaboration project. RMcC was supported by Programa Regional R17A10002 and R20F0002 (PATSER) ANID. We gratefully acknowledge the University of Magallanes (UMAG) and the University of Santiago (Carolina Diaz) for assistance with fieldwork; the NERC/SUERC AMS Radiocarbon Facility for providing initial range-finder radiocarbon dates; the NERC Isotope Geosciences Laboratory (NIGL, now National Environmental Isotope Facility, NEIF, at the British Geological Survey) and Melanie Lang for stable carbon isotope analysis; Aberystwyth University (David Kelly), Durham University (Neil Tunstall and Christopher Longley) and Edinburgh University (Chris Hayward) for use of their core scanning and microprobe facilities and technical support.
GPS data were collected using Trimble differential GPS, accurate to 0.1 m with values quoted as ±2-sigma (95% error). Other elevations were determined from Google Earth, and are on average, 6.7±5.9 m (2-sigma) higher than the geoid-corrected dGPS field measurements, hence, we assigned ±10 m errors. Lake water chemistry (pH, conductivity, temperature, dissolved oxygen) were measured in and around Lago Pato and several nearby lakes with a YSI600 Sonde. Light penetration was measured with a Secchi disc and water samples were taken at one metre intervals in the water column of Lago Pato. Data from lakes in Patagonia was collected from a near shore sampling point. Modelled annual and seasonal precipitation for 1979-2016 at Lago Pato and other ERA-INTERIM data and maps were generated using a BAS internal portal to the Dee et al. (2011) dataset. The dataset is arranged as follows Lake water chemistry Patagonia 2007.csv lake water chemistry dataset LP Bathymetry data.csv Lago Pato bathymetry dataset LP GPS data Lago Pato site and lake GPS data Modelled precipitation folder containing modelled annual, summer (December, January, February; DJF) and winter (June, July, August) precipitation data for the Lago Pato latitude and longitude
The WSI600 Sonde was calibrated according to manufacturer's instructions prior to use
