RV Investigator IN2023_V05: Marine Species Catch Data from Southeast Australia

Catch data for marine specimens collected by Museums Victoria during the RV Investigator voyage IN2023_V05. The voyage, titled 'Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 1)', took place between 27 June 2023 and 29 July 2023, departing from and returning to Hobart. Records include species identification, counts and/or weights, and are linked to sampling metadata such as station, location, depth, time, and gear type.

Use Cases

• Assess species composition and abundance based on catch counts and weights.
• Model species distribution patterns based on linked latitude, longitude, and depth metadata.
• Analyze long-term ecosystem changes based on data intended as a baseline for a 25-year study.
• Study sampling efficiency and gear type effectiveness based on linked gear metadata.

Strengths

• Data is linked to detailed sampling metadata including station number, location, depth, time, and gear type.
• Provides a baseline for a long-term (25-year) monitoring program of the southeast Australian marine ecosystem.
• Voyage dates (27 June 2023 to 29 July 2023) and ports (Hobart) are explicitly stated.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single voyage in southeast Australia.
