Advances in Antarctic chronology, paleoenvironment, and paleoclimate using microfossils: results from recent and legacy coring campaigns
Editor(s): David Harwood, Masao Iwai, Denise K. Kulhanek, R. Mark Leckie, and Francesca Sangiorgi
There have been several International Ocean Discovery Program expeditions to the Antarctic in recent years, including 374 (Ross Sea West Antarctic Ice Sheet History), 379 (Amundsen Sea West Antarctic Ice Sheet History), 382 (Iceberg Alley), and 383 (Dynamics of Pacific Antarctic Circumpolar Current, DYNAPACC) as well as numerous national campaigns on oceanographic vessels. These cruises have resulted in an abundance of new studies using microfossils as biostratigraphic and paleoceanographic indicators, in the identification of new taxa, and in advances in geochemical techniques utilizing microfossils or the biomarker they produce. In addition, work on legacy core collections continues to produce new and important Cenozoic records. This special volume provides an opportunity to publish important new studies that will greatly improve our knowledge of Antarctic micropalaeontology and climate evolution in a single special volume.
