Aquatic Substrate Spectral Library for Bolivar 2001

A 2001 spectral dataset from the Australian National Spectral Database (NSD) Aquatic Library, focused on the Bolivar area. It contains field spectroscopy measurements of marine and coastal substrates, supporting remote sensing analysis of natural and anthropogenic changes. The data is cited in a 2007 technical report for the Adelaide Coastal Waters Study.

Use Cases

• Calibrating satellite imagery for aquatic environments based on in-situ spectral signatures.
• Analyzing changes in coastal substrates due to natural or human-induced processes.
• Conducting end-member studies to decompose mixed spectral signals from imagery.
• Supporting environmental monitoring and reporting for coastal water studies.

Strengths

• Part of the authoritative Australian National Spectral Database (NSD), a national reference resource.
• Directly supports a published, peer-reviewed technical report (ACWS Technical Report No.6, 2007).
• Focuses on a specific, documented location and time (Bolivar, 2001) for precise analysis.

Limitations

• Critical metadata (row count, file size, specific columns, license) is completely absent from all source records.
• Data access requires navigating to an external URL (cmi.ga.gov.au) with no direct download or preview available.
• The 'last updated' metadata field shows a future date (2026-04-16), indicating a potential system error or misconfiguration.
