Antarctic fast ice at Cape Evans was the site for this 3-terabyte dataset collected during two field campaigns in November/December 2018-2019. It consists of high-resolution under-ice imagery from a custom sled system, ice core scans, and auxiliary data like irradiance measurements and water samples for chlorophyll-a analysis. The data were gathered by an AGP and NZARI collaboration to test an under-ice surveillance system for mapping sea-ice microbial habitats.
Use Cases
- Mapping spatial patterns of under-ice amphipod communities based on high-resolution near-horizontal imagery.
- Analyzing relationships between light conditions and under-ice habitats based on TriOS RAMSES irradiance data.
- Developing photogrammetry and image analysis techniques for sea-ice microbial communities based on the in-situ and ex-situ HI imagery.
- Correlating biological activity with ice physical properties based on auxiliary ice core section samples and particulate absorption spectra.
Strengths
- 3 terabytes of high-resolution under-ice imagery and auxiliary data.
- Data collected under a wide range of natural and manipulated light conditions for methodological testing.
- Includes multiple data modalities: imagery, irradiance measurements, and filtered ice core samples for pigment analysis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and specific file sizes are unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update is 2026-07-22 02:26:30.127071.
