Abstract
This dataset includes concentrations of total mercury (THg), total methylated mercury (MeHg), total lead (TPb), total manganese (TMn), and dissolved manganese (DMn) in seawater. Samples were collected in December as part of cruise 2019711, Q4, in the northern Barents Sea as part of the Nansen Legacy project. Concentrations were measured at seven different stations using GOFLO bottles attached sequentially and sampled using trace metal clean techniques. THg, MeHg, TPb, and TMn were collected unfiltered. DMn was filtered through a 0.2µm Sartorius Sartobran filter. Additional samples deeper than 500m were collected at stations P6 and P7 using Niskin bottles attached to a rosette. THg was measured by cold vapor atomic fluorescence spectrometry (CVAFS). MeHg was measured by species-specific isotope dilution gas chromatography sector field inductively coupled plasma mass spectrometry (ID-GC-SF-ICP-MS). TPb, TMn, and DMn were measured by ICP-MS.
