DOWNLOADING DATA VIA FTP
Data can be downloaded through a Web browser or command line via FTP. When using a Web browser, the FTP link first directs you to an Optional Registration Form that if filled out, will allow you to receive notifications about updates or processing changes related to that specific data set. After completing the Optional Registration Form, the FTP directory becomes available. For additional help downloading data through an FTP client, go to the How to access data using an FTP client support page.

Data Acquisition and Processing
Samples of 25 to 100 cm in length were obtained as longitudinal slices (outside edges removed) from the WAIS Divide WDC06A ice core. Water stable-isotope concentrations were measured by laser spectroscopy (Picarro L2120-i instrument) at the University of Washington, and are reported as δ18O deviations in per mil (‰) from Vienna Standard Mean Ocean Water (VSMOW), normalized to VSMOW and Standard Light Antarctic Precipitation (SLAP), where δ18O = R/RVSMOW-1, R is the abundance ratio of 18O/16O in water, δ18O VSMOW = 0.0‰ and δ18O SLAP = - 55.5‰.
