Rock Dredging Samples from RV Investigator Voyage IN2024_T01

An inventory of physical rock dredge samples collected during the Marine National Facility RV Investigator voyage IN2024_T01. The dataset includes sample identifiers, collection metadata, and detailed macroscopic geological descriptions. Samples are primarily composed of mafic volcanic lithologies like porphyritic basalts, with additional manganese nodules and minor sediment.

Use Cases

• Classifying seafloor lithology based on detailed macroscopic descriptions of colour, grain size, and texture.
• Mapping the distribution of mafic volcanic rocks based on sample location and water depth metadata.
• Studying sample alteration and vesicularity to infer geological history and processes.
• Linking physical sample characteristics to associated high-resolution photographic records for visual validation.

Strengths

• Includes detailed macroscopic descriptions using standard geological attributes like mineralogy and groundmass texture.
• Provides links to supporting imagery, including high-resolution photographs and thin section data where available.
• Documents sample storage information to enable physical access 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.
• Data may reflect geographic and temporal bias inherent to the specific research voyage.
