Electron backscatter diffraction was used to quantify grain boundary misorientations in experimental samples doped with deuterium-enriched water. The same samples were subsequently studied with nanoSIMS to look for boundary enrichment of D2O. Grain boundary misorientation data were collected using EBSD to test the possibility of misorientation angle dependence on measured D2O concentrations. No clear misorientation dependence was observed. Folders names include the name of the PDRA who collected the data. Data are images, text files (ctf), and other file formats that can be opened using Oxford Instruments EBSD software. Supporting EDS files are available on request

This dataset provides a 308 year (1702-2009) deuterium isotope record from the Ferrigno 2010 (F10) ice core. The core was drilled on the Bryan Coast in Ellsworth Land, West Antarctica, during the austral summer 2010/11. The record was measured using a Los Gatos Liquid Water Isotope Analyser at 5cm resolution, corresponding to ~14 samples per year, with annual averages calculated for January-December. Funding was provided by the NERC grant NE/J020710/1
