Abstract:
During the JR19002 Icebergs 3 cruise, dissolved organic carbon samples from the surface seawater were collected from Zodiacs, and samples from the sediment-seawater boundary were collected from the CTD rosette. Samples were collected with the motivation of sampling glacially-derived material and determining the biogeochemical composition and environmental significance with respect to iron and carbon cycling. Three main sites were visited during JR19002 from south to north: Marian Cove, Maxwell Bay, King George Island; Borgen Bay, Anvers Island; and Sheldon Cove, Ryder Bay, Adelaide Island.

| Parent Dataset: | N/A |
| Quality: | Sample concentrations were calibrated using certified standard potassium hydrogen haphthalate (1000 +/- 10 mg C L-1, Sigma Aldrich). Repeat standard measurements had a variance of less than 5 percent. The limit of quantification was 0.039 mg L-1 (5 S.D. x limit of baseline). | |

| Lineage: | Data was collected during the JR19002 Icebergs 3 cruise from Zodiac boats by hand or from the CTD rosette. Seawater was filtered through 0.2 micrometer filters. Concentrations for DOC (250 mL) were measured with a Shamdzu TOC-LCHN, with a high-sensitivity catalyst. Sample concentrations were calibrated using certified standard potassium hydrogen haphthalate (1000 +/- 10 mg C L-1, Sigma Aldrich). Repeat standard measurements had a variance of less than 5 percent. The limit of quantification was 0.039 mg L-1 (5 S.D. x limit of baseline). | |
