Detailed Data Description

This data set includes three Roosevelt Island Climate Evolution (RICE) ice core samples drilled on Roosevelt Island, Ross Ice Shelf, Antarctica. The RICE elements analyzed were: Sr, Cd, Cs, Ba, La, Ce, Pr, Pb, Bi, U, As, Li, I, Al, S, Ca, Ti, V, Cr, Mn, Fe, Co, Na, Mg, Cu, Zn, K, and top and bottom depth.

The RICE ice core was processed at a very high resolution in order to analyze it better in order to understand the phasing sequences in the Arctic and Antarctic abrupt climate change, even at the level of individual storm events; and to determine the impact of changes in the Westerlies and the Amundsen Sea Low on past, present, and future climate change. The study should also show how sea ice extent has varied in the area, to compare the response of West Antarctica climate to other regions during glacial/interglacial cycles, and to determine how climate of the Ross Sea Embayment changed during the transition from the Ross Ice Sheet to the Ross Ice Shelf. The intellectual merit of the RICE deep ice core project is that it is expected to provide a 30kyr long and possibly 150kyr long extremely high-resolution view of climate change in the Ross Sea Embayment Region and data essential to test and understand critical questions that have emerged as a consequence of the recent synthesis of Antarctic and Southern Ocean climate change presented in the Scientific Committee for Antarctic Research (SCAR) document: Antarctic Climate Change and the Environment (ACCE 2009).

Data Acquisition and Processing

The RICE Ice core was drilled on Roosevelt Island, Ross Ice Shelf, Antarctica as part of a multi-nation collaboration, then cut and melted in the GNS Science laboratory in Wellington, NZ. Inductively Coupled Plasma Mass Spectrometer (ICP-MS) samples were shipped to the Climate Change Institute in Orono, ME to be analyzed. ICPMS samples were buffered to one percent nitric acid solution with an internal standard and analyzed 30 days after acidification.
