Abstract:
This dataset contains measured labile particulate and total particulate trace element concentrations (Al, Ti, V, P, Fe, Mn, Co, Ni, Cu, and Cd) of water bottle samples collected during GEOTRACES expedition GN05 (PS100) between 21 July and 1 September 2016 on Northeast Greenland Shelf. Samples were collected using the ultra-clean CTD rosette, equipped with 24 × 12 L GoFlo bottles following GEOTRACES sampling protocols (Cutter et al., 2017; https://www.geotraces.org). Particulate TM samples were collected onto pre-acid leached Polyethersulfone (PES) Membrane filters (0.2 µm, Sartorius) with 1.2 - 4.1 L of seawater filtered per sample. Labile particulates were determined after applying a weak acid leach with a mild reducing agent and a short heating step with a total leach time of 2 h. Total particulates were then analyzed following a 15 h reflux digest at 150 °C using a mixture of hydrofluoric acid and nitric acid. The validation of labile and total particulate trace metal analyses was monitored by reference materials BCR-414 and PACS-3. Information on the analytical procedure including reference materials and limits of detection can be found in related published manuscripts. The concentrations reflect the mean and the corresponding uncertainty is calculated as the standard deviation to replicate measurements. Uncertainty is calculated as one standard deviation (1σ, STD) to replicate measurements via ICP-MS. Use of quality flags (QF) according to GEOTRACES policy (https://www.geotraces.org/geotraces-quality-flag-policy/).
