A Russian team, however, has been active establishing a chronology of deuterium from snow-cores and -pits near the Vostok station (A.A. Ekaykin, et al., 2014). A summary (www.ncdc.noaa.gov/paleo/study/22532) with digital data became available in May, 2017. The data include annual measurements from 1654 to 2010, providing an overlap with the ice-core record that enables an assessment of present conditions from the perspective of ice-core record.
