Diatoms of the Antarctic – Environmental Interpretation of the Middle Pliocene at Site 697

Abstract

The Ocean Drilling Program (ODP) was an international cooperative effort that conducted 110 expeditions and drilled 2000 drill holes (IODP website). Site 697 is a drill hole located in the Weddell Sea within the Jane Basin and is 3480 meters below sea level. Site 697 is the deepest of a three-site depth transect of the South Orkney microcontinent (SOM) drilled during ODP Leg 113 (Barker, Kennett et al., 1988)[See O'Connell, Fig. 1, this volume].
