©2020 Biological and Chemical Oceanography Data Management Office.This dataset is a compiled global dataset of inorganic and organic carbon and biogenic silica concentrations measured by in situ pumps. We merged the Multiple Unit Large Volume in-situ Filtration System (MULVFS, Bishop et al. 1985) LVP PIC, POC, and bSi dataset published partially in Lam et al. 2011 with new data collected using McLane in-situ pumps equipped with two size-fractionating filters during the GEOTRACES program. The filter sizes generally consist of a 51 micrometer (μm) or 53μm pre-fi...
Show moreThe data in this compilation come from three existing datasets already on BCO-DMO:
(1) The Compilation of MULVFS size-fractionated POC, PIC, and bSi data (https://www.bco-dmo.org/dataset/884057; DOI: 10.26008/1912/bco-dmo.884057.1),
(2) GEOTRACES GP16 Particle Composition (https://www.bco-dmo.org/dataset/668083; DOI: 10.1575/1912/bco-dmo.668083.1), and
(3) GEOTRACES GA03 Particulate Composition (https://www.bco-dmo.org/dataset/3871; DOI: 10.1575/1912/bco-dmo.3871.5.1).
The collection and measurement methodologies for each of these datasets are described in detail on their respective BCO-DMO dataset landing pages.
For this dataset, we merged the Multiple Unit Large Volume in-situ Filtration System (MULVFS, Bishop et al. 1985) LVP PIC, POC, and bSi dataset published partially in Lam et al. 2011 with new data collected using McLane in-situ pumps equipped with two size-fractionating filters during the GEOTRACES program. The filter sizes generally consist of a 51 micrometer (μm) or 53μm pre-filter that collects large particles, followed by a 0.8μm or 1μm filter that collects smaller particles. We annotate large size fraction particles (>53μm or >51μm) as "LSF", and small size fraction particles (1-53μm or 0.8-51μm) denoted "SSF" (small size fraction).
