Mertz Drift Sediment Data from Sub-Bottom Profiling and Cores

Recently discovered drift deposits on the Antarctic continental shelf provide access to Holocene palaeoceanography data. The dataset from the George Vth Basin includes evidence from 35 Khz sub-bottom profiling and sediment cores. It is hosted by the Australian Ocean Data Network and was last updated in 2026.

Use Cases

• Reconstruct Holocene bottom current activity based on sediment core evidence.
• Study Antarctic Bottom Water source variations based on drift deposit analysis.
• Model paleoceanographic conditions in deep shelf basins based on sub-bottom profiling data.

Strengths

• Focuses on a recently discovered and previously inaccessible geological feature.
• Data includes evidence from 35 Khz sub-bottom profiling and sediment cores.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
