Main Achievements
Stéphane Blain received his Ph.D. in chemical oceanography from the University of Brest in 1992. In 1993, he served as a post doc at the Moss Landing Marine Laboratories during the preparation of IRONEX1. He is actually professor of chemical oceanography at the University Pierre et Marie Curie (Paris). He is working at the Marine station of Banyuls sur Mer, where he has founded and directed the Microbial Oceanography Laboratory (2010-2013), a research unit in partnership with the UPMC and the CNRS. His research interests are the functioning of the biological pump of CO2 in the ocean with focus on iron biogeochemistry and the Southern Ocean. He is also involved in the development of new analytical tools and methods for in-situ chemical oceanography.
He has initiated the project KEOPS (KEOPS: Kerguelen Ocean and Plateau compared study) ten years ago. The main objective of KEOPS is to study the impact of natural iron fertilization of the Southern Ocean. KEOPS is international project that gathered researchers from 10 French laboratories and foreign colleagues from different nations (Australia, Belgium, Chili, The Netherlands, South Korea, USA, UK). The first phase of this project was conducted in 2004-2009 and and the second phase took place in 2011-2014). All together more than 100 publication were produced.. As principal investigator of KEOPS, He has co-organized two special sessions with colleagues of the National Oceanographic Center of Southampton (OSM, Hawaii 2006) and with colleagues of the Alfred Wegener Institute (ASLO meeting, Orlando 2013). He was involved in the SCOR WG and invited to international workshops and conferences. The strong collaboration with australien colleagues during KEOPS has led to the invitation of S. Blain as invited professor of Tasmania University in 2015 and to the participation at the HEOBI cruise (Jan-Feb 2016) at Heard Island.
During the past 20 years he has been very interested in observing systems. In 1997, he has organized an international symposium on marine analytical chemistry for the monitoring of oceanographic research. He has participated to the first development of nutrient in situ chemical analyzers and to the deployments of biogeochemical sensors on buoys. Recently, he has used fluorescence sensors mounted on elephant seals of Kerguelen to produce the first two dimensional climatology of chlorophyll in a region of the Southern Ocean. He is presently Co-PI of the project SOCLIM (Southern Ocean and Climate) dedicated to the study of the carbon cycle in the Southern, using innovative tools like BGC-Argo floats and instrumented moorings.
Besides the research activities described above S. Blain has also explored the multiple facets of the interactions between iron and microorganisms using laboratory experiments. He was the PI of the ANR BACCIO (Biomolecular approach of the iron and carbon cycle in the ocean) project where the metabolic response of heterotrophic bacteria to iron limiation was extensively studied. In collaboration with other colleagues of the laboratory he has for the first time applied genetic tools (mutants and bioreporters) to elucidate the role of ferrritine in iron homeostasis of picophytoplancton. New studies are now underway to apply the same approaches to heterotrophic bacteria.
