Brief description

These data describe the field deployments of the trace-metal passive sampling tools, diffusive gradients in thin-films (DGT). Deployments occurred over the summer 2017/2018 season in the coastal region adjacent to Casey and Wilkes stations. Deployments of DGT to the nearshore marine environment was achieved with small watercraft and shallow (less than 5m deep) moorings, which were left in situ for 21-37 days, depending on the site.

Lineage

Progress Code: onGoing
Statement: Some DGT moorings were lost due to iceberg ensnarement. These are document in the dataset.

Notes

Purpose
These data provide DGT-labile trace metal concentrations time-averaged over their deployment duration. This is valuable for monitoring contaminant fluxes to the environment or for understanding the biogeochemical cycling of trace metals in Antarctic coastal areas.

Data time period: 2017-12-27 to 2018-02-11
