Description
Eight seismic profiles totaling about 2000 km and bathymetric data collected by the RAT "Rig Seismic" vessel in February 1992 provide coverage of the Christmas Island area. The Australian Ocean Data Network compiled this data to produce a new bathymetric map at a 1:1,000,000 scale, offering more detail than previous maps from the 1970s and 1980s. The dataset likely contains information on seabed morphology, sediment thickness, seamount distribution, and the structure of the Java Trench.
Use Cases
Compile high-resolution bathymetric maps based on seismic and bathymetric data.
Assess sediment thickness for offshore mineral resource evaluation.
Analyze seamount distribution and tectonic features like the Java Trench.
Compare new digital data with older analog maps to identify previously missing features.
Strengths
Includes about 2000 km of seismic profiles and nearly twice as much bathymetric data.
Compiled a new bathymetric map at a 1:1,000,000 scale, providing more detail than previous 1:5,000,000 or 1:10,000,000 maps.
Integrates high-quality data from the "Rig Seismic" survey and digital water depths from the USA National Geophysical Data Bank.
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 on a specific area around Christmas Island.
