title: Phytoplankton pigment concentrations of seawater sampled during the Antarctic Circumnavigation Expedition (ACE) during the Austral Summer of 2016/2017.

description: <strong>Dataset abstract</strong> This dataset contains phytoplankton pigment concentrations sampled during the Antarctic Circumnavigation Expedition (ACE) Leg 1-3 and analysed using high performance liquid chromatography. Water samples were collected from the underway seawater supply every 3 hours and at multiple depths from select CTD (conductivity, temperature and depth) rosette deployments. Pigment concentrations have been quality controlled. This circumpolar dataset contains the main pigment concentrations of phytoplankton and can be used to infer phytoplankton biomass and class composition. <strong>Dataset contents</strong> ace_phytoplankton_pigments_20200511CURRSGCMR.csv, data file, comma-separated values ace_phytoplankton_pigments_lod.csv, metadata, comma-separated values ace_phytoplankton_pigment_concentrations_change_log.txt, metadata, text data_file_header.txt, metadata, text README.txt, metadata, text Pigment concentration values below the limit of detection are reported with fill value ‘NaN’. Any null values are reported with fill value ‘NaN’. <strong>Change log</strong> <strong>v1.1</strong><br> - Added statement to ReadMe in original data collection statement acknowledging analysis performed by Celine Dimier<br> - Added statement to Acknowledgements section of DOI acknowledging analysis performed by Celine Dimier<br> - Metadata for samples have been updated: AT/ACE/2/1/28/1026/DA/13 A_C07N17 and AT/ACE/1/1/14/402/DA/10<br> - Corrected ship name to R/V Akademik Tryoshnikov<br> - Corrected citation DOI for one minute cruise track <strong>v1.0 </strong><br> - Initial release of phytoplankton pigment concentration dataset.
description: The Antarctic Circumnavigation Expedition was made possible by funding from the Swiss Polar Institute and Ferring Pharmaceuticals. This research was partially supported by the Australian Government through the Australian Research Council's Discovery Projects funding scheme (project DP DP160103387). The analysis of pigments was performed by Céline Dimier from the SAPIGH (Service d'Analyses de Pigments par HPLC) analytical platform of the Insitut de la Mer de Villefranche (CNRS and Sorbonne Université).
