An inventory of rock dredge samples collected during the Marine National Facility RV Investigator voyage IN2024_T01. The dataset includes sample identifiers, collection metadata, and detailed macroscopic descriptions of recovered materials, primarily mafic volcanic lithologies. It is provided by the Australian Ocean Data Network and was last updated on June 4, 2026.
Use Cases
- Classify seafloor lithologies based on detailed macroscopic descriptions including colour, grain size, and mineralogy.
- Map the distribution of mafic volcanic rocks and manganese nodules based on sample location and water depth metadata.
- Assess sample alteration and vesicularity for petrological studies based on standard geological attributes.
- Locate physical samples for laboratory analysis using the provided sample storage information and links to photographic records.
Strengths
- Includes detailed macroscopic descriptions using standard geological attributes like lithology, mineralogy, and texture.
- Provides links to supporting high-resolution photographs and thin section data for visual context.
- Documents sample availability and storage to enable discovery and reuse by the research community.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update was 2026-06-04 07:40:01.904755.
