Three terabytes of high-resolution imagery and auxiliary data collected from Antarctic fast ice at Cape Evans during November and December 2018-2019. The dataset was acquired by the IMAS/AGP under-ice HI system and a custom ice core scanner for the 'On Thin Ice' grant, a collaboration between AGP and NZARI. It includes in-situ transects under natural light, ex-situ ice core scans, irradiance measurements, fluorometric samples, and media footage.
Use Cases
- Mapping spatial patterns of under-ice microbial and amphipod communities based on high-resolution imagery.
- Analyzing the relationship between light conditions and under-ice habitats based on TriOS RAMSES irradiance data.
- Developing photogrammetric models of sea-ice structure based on scanned transects and ice core sections.
- Studying pigment composition and chlorophyll-a concentration in sea-ice based on HPLC and fluorometric sample data.
Strengths
- Dataset size is explicitly stated as 3 terabytes, indicating substantial data volume.
- Data collection covers both in-situ natural light and ex-situ manipulated light conditions, providing comparative context.
- Includes multiple auxiliary data types such as irradiance measurements, chlorophyll-a samples, and media footage, enhancing analysis potential.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for certain statistical methods.
