Multiple sea-ice and seafloor hyperspectral imaging transects collected at Cape Evans, Antarctica, in November 2023. The data were acquired using the HIcyBot remotely operated vehicle (ROV) as part of a long-term NIWA benthic monitoring program. The dataset also includes hyperspectral scans of retrieved organisms to support habitat mapping algorithm development.
Use Cases
- Develop habitat mapping algorithms based on hyperspectral scans of algae, urchins, and sea-stars.
- Model biomass and photophysiology of under-ice communities using hyperspectral and RGB imagery.
- Assimilate multi-scale biophysical data with known regional information for change monitoring.
- Test and refine under-ice hyperspectral imaging and photogrammetric payloads for ROV systems.
Strengths
- Data includes co-located hyperspectral and normal RGB imagery from a dual-camera system.
- Each hyperspectral frame is timestamped and linked to underwater position via a GNSS-integrated USBL transponder.
- Imaging transects are 10-40 meters long, providing spatial context.
Limitations
- Data processing is still underway as of April 2025, indicating it is a preliminary release.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
