| contents | Plant, soil and algal rock scrape samples were taken in both April and August 2013 on Disko Island, West Greenland using a small trowel, placed into plastic bags, and subsequently transferred into glass vials for freeze drying, with samples powdered using a liquid nitrogen freezer mill and a pestle and mortar. Surface sediments were taken from the uppermost 0.5 cm interval of a HON-Kajak core from lakes Disko 1, 2, & 4. Samples were analysed for carbon isotopes (δ¹³C~org~) and C~org~/N ratios (including provision of TOC and N) using a Costech ECS4010 elemental analyser (EA) coupled to a VG Triple Trap and a VG Optima dual-inlet mass spectrometer (BGS, Keyworth). Analyses were completed as part of Mark A. Stevenson's PhD research while based at the University of Nottingham, UK (Stevenson, 2017, http://eprints.nottingham.ac.uk/46579). Samples are arranged here by broad specimen group for subsequent data exploration. Acknowledgements: Mark Stevenson gratefully acknowledges the receipt of a NERC/ESRC studentship (ES/J500100/1). We acknowledge grants IP-1393-1113 & IP-1516-1114 from the NERC Isotope Geosciences laboratory (NIGL) for the analysis of δ¹³Corg & C/N ratios on sediment, soil and plant samples. We thank Christopher Kendrick for technical support. Financial support for fieldwork was awarded via the INTERACT transnational access scheme (grant agreement No 262693) under the European Community's Seventh Framework Programme and UK RI NERC grant NE/K000276/1.
