Antarctic Sediment Core Samples from Prydz Bay and Mac.Robertson Shelf, 1993

Fifteen gravity cores were collected from Prydz Bay and the Mac.Robertson Shelf during Voyage 7 of the 1992/93 Antarctic shipping season. The Australian Ocean Data Network hosts this cruise preview report detailing a marine geoscience program aimed at studying Quaternary environmental change. Sampling targeted sites to elucidate sedimentation processes and past glacier behavior on the Antarctic shelf.

Use Cases

• Calibrating climatic models based on records contained in ice and sediments.
• Studying past behavior of the Lambert Glacier-Amery Ice Shelf system based on sediment cores from Prydz Bay.
• Interpreting Late Quaternary history based on gravity cores from Prydz Bay and the Mac.Robertson Shelf.
• Elucidating modern sediment types based on grab samples collected in Prydz Bay and the Mac.Robertson Shelf.
• Inferring post-glaciation iceberg gouging extent based on bathymetry and 3.5kHz echo sounder data.

Strengths

• Targets a specific, important site for studying the largest ice stream draining the East Antarctic Ice Sheet.
• Includes data from fifteen gravity cores and additional grab samples collected during a dedicated Antarctic voyage.
• Combines sediment core data with bathymetry and 3.5kHz echo sounder records for interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on two Antarctic regions.
