Biogenic and lithogenic silicon along the GEOTRACES South West Indian Ocean section (SWINGS-GS02)

Data of parameters presented as figures in the manuscript: Biogenic silica (BSi: µmol.L-1), Lithogenic silicon (LSi: µmol.L-1), Total Chlorophyll a (TChla: mg.m-3) and Fucoxanthin (Fuco: mg.m-3).

Note that:

- Total fraction for BSi and LSi is available from Niskin bottles (> 0.8 µm) and in situ pumps (> 0.45 µm);

- Size-fractions for BSi and LSi is available from in situ pumps only (5-53 µm; > 53 µm);

- Total fraction for TChla and Fuco is available from Niskin bottles (> 0.7 µm).

- Integrated data (0-200 m) is available from Niskin Bottles.

Acronym explanations:

- Sampling type: ISP = In Situ Pump; ISP-SF = In Situ Pump with Size-Fraction; NSK = Niskin.

- Method used for BSi and LSi computation: NOC = No Correction applied; RAG = Correction using the method used from the protocol established by Ragueneau et al. (2005); ACR = Average Crustal Ratio method used when one of the criterion from the protocol established by Ragueneau et al. (2005) is not respected.

- bdl = Below Detection Limit

For further explanations in the method, should you please refer to the Material and Methods section in the manuscript (revised version submitted in Marine Chemistry).

The authors would like to thank Catherine Jeandel and Hélène Planquette as the SWINGS chief scientists; the captain and the crew of the R/V “Marion Dufresne II” for assistance on board as well as Marine Piéjus for sampling and filtering on-board; Mustapha Benrahmoune (LOCEAN) for managing clean laboratory; Pierre Burckel and the PARI analytical platform (IPGP) for the Al concentrations measurements. The SWINGS program was supported by the French Research program of INSU-CNRS LEFE-CYBER (Les Enveloppes Fluides de l’Environnement – Cycles biogéochimiques, environnement et ressources) and the French ANR (Agence Nationale de la Recherche, ANR-19-CE01-0012). This work was part of the Master’s degree research of V. Deteix.

Figure: (a) Map of the SWINGS study area (South West Indian Ocean sector) showing the locations of the stations of this study. The coloured dots represent the different station types for sampling: green for in situ pump and Niskin bottles, orange for Niskin bottles, grey for pigment sampling only. The colour represents the detailed map of the satellite-derived surface chlorophyll a concentration averaged over February 2021 (MODIS L3 product). The black lines represent the 1000 m isobath from GEBCO bathymetry. The dotted lines represent the positions of the Southern Ocean fronts determined from satellite-derived surface temperature averaged over February 2021 (CMEMS L4 product): STF = Subtropical Front (18°C); SAF = Subantarctic Front (13°C); PF = Polar Front (4.5°C). Additional maps show details of areas of particular interest: (b) Prince Edward islands area; (c) Crozet Archipelago; (d) Kerguelen Plateau.
