Circum-Antarctic Paleobathymetry to 30° South: Present to 75my (NCEI Accession 0304547)
This software package models the paleobathymetry of the circum-Antarctic oceans back to the Late Cretaceous. It is based on a revised tectonic model of the circum-Antarctic region, and incorporates features such as spatially variable subsidence rates, refined rotation poles and a detailed treatment of selected areas.
The software output consists of color-coded maps at user-specified Cenozoic ages and the associated gridded paleobathymetry for all oceans lying south of 30°S.
NCEI decommissioned the Circum-Antarctic Paleobathymetry to 30° South: Present to 75my in May 2025 with no plans for further updates. Comments and questions may be sent to: ncei.info@noaa.gov
