A 2700-year annual timescale and accumulation history for the RICE (Roosevelt Island Climate Evolution) ice core from Roosevelt Island, Ross Sea region, West Antarctica.
The timescale was constructed by a combination of manual and automated annual-layer counting, and subsequently validated by volcanic and methane matching to the WAIS Divide ice core on the WD2014 chronology. It constitutes the top part of the Roosevelt Island Ice Core Chronology 2017, RICE17.
Past annual accumulation rates were obtained from the annual layer thicknesses, after correction for firn densification and layer thinning due to ice flow. The uncertainty of past accumulation rates was estimated based on the uncertainty in ice flow thinning with depth.
