Winter phytoplankton distribution, pigments, macronutrients and trace metals (dissolved and particulate) in the upper 250m of the Indian Southern Ocean along the 30°E transect (GEOTRACES GIpr07)

This data set shows winter phytoplankton distribution and trace metal data parallel sampled from the upper 150 m of the Indian sector of the Southern Ocean along the 30°E longitude during the Winter 2017 Cruise onboard the SA Agulhas II. The data set contains phytoplankton pigment concentrations (HPLC), phytoplankton community composition (group chla concentration and percentage via CHEMTAX), macronutrient concentrations, and dissolved and particulate trace metal concentrations. The data set also contains various other parameters (Turner Fluorometer Chla and POC) that were previously published in Weir et al. (2020) for this cruise and relevant to this study.

Also contained is a file for all the trace metal data (dissolved and particulate) in the upper 250m of the transect and associated trace metal star (Metal*) values calculated according to Moore (2016) - http://dx.doi.org/10.1098/rsta.2015.0290.

This data is related to the Preprint by Viljoen et al. titled: Winter dynamics of phytoplankton and micronutrients in the Southern Ocean available on ESS Open Archive at: https://doi.org/10.22541/essoar.173884384.49518335/v1.

Original HPLC phytoplankton pigment concentration data and their limits of detection is availble in a separate repository at: https://doi.org/10.5281/zenodo.14610498.
