This repository contains raw data from flow cytometry, diagnostic pigments, and particulate organic carbon and nitrogen analyses, collected during phytoplankton incubation experiments in the Southern Ocean in February 2022 (Indian section). One incubation was conducted in the Polar Frontal Zone and the other in a High-Nutrient, Low-Chlorophyll (HNLC) region. These experiments were carried out under various treatments, including the addition of Patagonian dust, warming, and acidification.

This work was financially supported by the SO-dust project (Responses of phytoplankton to Patagonian dust input and anthropogenic changes in the future Southern Ocean, PI M. Boye) funded by the LEFE-CYBER program of the French INSU-CNRS. The experiments were conducted on board the French R.V. Marion Dufresne II and we extend our special thanks to the Captain and the crew members for their assistance at sea and to the French National Observation Service in the Indian Ocean (SNO OISO) of INSU-CNRS led by Dr Claire Lo Monaco (LOCEAN, Paris) for joining their oceanographic campaign. We thank Dr Julia Uitz and Céline Dimier (Institut de la Mer de Villefranche, France) for the analyses of the phytoplankton pigment concentrations using HPLC within the National Analytical Platform SAPIGH of INSU-CNRS. We also extend special thanks to the French MAP-IO program (Marion Dufresne Atmospheric Program-Indian Ocean) coordinated by Dr Pierre Tulet (LACy, France) for the support in a flow cytometer onboard the ship. Thanks also to Emma Moreau (IPGP, Paris) for her help in data processing and to Prof Rémi Losno (IPGP, Paris) for providing the Patagonian soil.
