• Core: Roosevelt Island Ice Core (RICE) Combined Record AMJJASON Season Isotope Data

  Antarctica New Zealand

  Here we examine the water stable-isotope data from the Roosevelt Island Climate Evolution (RICE) ice core. In this study, we use empirical orthogonal function (EOF) analysis to investigate the relationship between RICE ice-core oxygen-18 isotopes (δ18O) and Southern Hemisphere atmospheric circulation during the extended austral winter (April–November)....
