Field deployments of diffusive gradients in thin-films (DGT) passive samplers for trace-metal monitoring occurred in the Antarctic nearshore environment. AU_AADC collected this data during the 2017/2018 summer season near Casey and Wilkes stations. Samplers were deployed on moorings for periods of 21 to 37 days.
Use Cases
- Analyze temporal trends in trace metal concentrations from time-series deployment data.
- Compare trace metal bioavailability between sites near Casey and Wilkes stations.
- Correlate deployment duration (21-37 days) with accumulated metal concentrations.
- Assess spatial variability of contaminants in shallow (<5m depth) Antarctic coastal waters.
Strengths
- Data covers a full summer field season (2017/2018).
- Deployments provide integrated measurements over 21-37 day periods.
- Spatial coverage includes two distinct Antarctic station areas.
Limitations
- Sample size (number of deployments or rows) is unknown.
- Specific trace metal analytes and their concentration values are not detailed.
- Data is from a single season and may not represent long-term trends.
