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 ... : Under "Further details" subsets of this dataset are provided which are arranged by different groups. ...
