AU_AADC collected data on the heavy metal content of the amphipod Paramoera walkeri during the summer of 2003/04. Measurements consist of parts per million (ppm) concentrations for 45 heavy metals, derived from specimens deployed in experimental mesocosms near Casey station. This work was part of ASAC project 2201 to assess natural variability and human-induced change in Antarctic nearshore communities.
Use Cases
- Analyze ppm concentrations of 45 heavy metals to assess bioaccumulation levels in Paramoera walkeri tissue.
- Compare heavy metal profiles between specimens from potentially impacted Brown Bay sites and control sites like O'Brien Bay.
- Investigate temporal changes in metal uptake by analyzing data from three separate two-week experimental deployments.
- Model the relationship between site conditions (impacted vs. control) and specific metal concentrations detected via ICP-MS analysis.
Strengths
- Covers 45 distinct heavy metal analytes per specimen.
- Includes data from three separate experimental runs over a summer season.
- Provides comparative data from both impacted and control sites.
Limitations
- Sample size is limited to specimens from one Antarctic summer and four specific sites.
- Data is temporally stale, collected in 2003/04 with no indicated updates.
- Unknown row count and specific file format details.
