SCIENTIFIC REPORT
ABSTRACT
Ocean Drilling Program (ODP) Leg 188 was drilled based on one of five
linked proposals to decipher Cenozoic glacial history and
paleoenvironments of Antarctica by drilling transects across the
continental margin in five different regions. ODP Leg 178 (Antarctic
Peninsula) was the first such proposal to be drilled. Three sites were
drilled on Leg 188, with one each on the Prydz Bay continental shelf,
slope, and rise. These sites provide records of the transition from East
Antarctic preglacial to glacial conditions on the shelf (Site 1166); the
variability of onshore erosion areas and glaciomarine depositional
settings, during latest Neogene glacial-interglacial periods, on the slope
(Site 1167); and the long-term, lower to upper Miocene transition from
temperate to cold-climate glaciation, with superimposed short-term
glacier fluctuations since early Miocene time (Site 1165). These sites
document the paleoenvironments for select periods during Cenozoic and
older times as Antarctica transformed from a temperate to polar setting.
