Dr. C. Marcela Borel
She is a Researcher of CONICET (National Scientific and Technical Research Council, Argentina) at the Instituto Geológico del Sur (INGEOSUR, CONICET-UNS, Bahía Blanca) [Geological Institute of South].Her doctorate (PhD in Geology, 2003), concerned with Holocene paleoenvironmental changes in estuarine and coastal brackish-water systems of Southern Pampa, was conducted at the Universidad Nacional del Sur (UNS) [National University of South].
Her current research focuses primarily onthe diversity and distribution of organic-walled dinoflagellate cysts (dinocysts), including those of toxic species, from recent sediments of the Argentinian Shelf and its relationship with the physico-chemical characteristics of surface water masses and sediments. The tracing of Holocene environmental change in the Southwestern Pampa-Northern Patagonia coastal region by a multi-proxy approach including palynology (dinocysts and other non-pollen palynomorphs), sedimentological characteristics and geochemical data is also an important objective of her work.
She had supervised one PhD thesis at UNS, and is currently supervising and co/supervising PhD studentsat the same institution and at the Universidad Nacional de Mar del Plata.Also she participated in five oceanographic cruises of R/V Puerto Deseado(CONICET-MINDEF, Argentina) and was the coordinator and chief scientist of the 2013 Cruise “Primavera Patagónica”. She conducts aScientific and Technological Research Project (PICT): “Present and Past of Frontal Zones of the Argentine Shelf: a biological and geological perspective of dinoflagellates” funded by Scientific and Technological Research Fund (FONCYT) of Argentina. The main objective of the Project is to improve the links between benthic dinocysts, cells in the planktonic stage, presence of their toxins, and hydrographic and sedimentological characteristics.She participated, in cooperation with researchers of the Marine Ecology Group of Alfred Wegener Institute, Germany, in recent multidisciplinary investigations on links between the presence of viable cysts of toxic dinoflagellates in bottom sediments, hydrographic characteristics and toxins of Argentinian Patagonian Shelf.

Dr. Carlos Lara
I am a marine biologist from Universidad Austral de Chile, with a doctorate degree in applied ecology. I am mainly interested in explaining the complex patterns of populations observed in costal marine ecosystems. I am currently working at the Center for Natural Resources and Sustainability Research at Bernardo O'Higgins University as a principal investigator and professor in Remote Sensing and Advanced Remote Sensing courses for the Faculty of Engineering. My main contribution concern is focused on understanding spatial and temporal variation of primary and secondary production in the coastal ocean. I approach this interest in complex dynamics through the use of empirical information derived from moorings and remote sensors, together with statistical modeling. This combined approach has allowed me to explore the effects of environmental and climatic oscillations and capture their discontinuous effects on biological responses. During the last years I bolstered my analytic skills through several international internships and courses where I have deepened my knowledge of statistics and remote sensing.
Dr. Giuseppe Siani
I am full professor in geologyat the University of Paris Sud. My research topics are aimed at reconstructing the recent Quaternary climate changes from a multidisciplinaryapproach (geochemistry, micropaleontology, tephrochronology, radiochronology14C) from the study of deep marine sediments. I amfocusing on the reconstruction of the chronology, duration and mechanismsbehindclimate changes. The temporal frameworkisconstrained if possible, by tephrochronology, a powerfultool of stratigraphic and chronologicalcorrelation of climaticevents to control the possible existence of synchronous or asynchronous events at the regional and inter hemispheric scale.
Dr. Stephanie Duchamp-Alphonse
My work aims to reconstruct paleoclimate changes and associated biogeochemical interactions within the Ocean-Atmosphere-System during the Cretaceous and the Quaternary, based on micropaleontological (coccoliths) and geochemical (COT, CaCO3, XRF, δ13C, δ18O) analyses of marine sediments. In recent years, I further centered my activity around coccolithophore productivity changes within the Southern Ocean in order to i) reconstruct past changes in seasurface conditions (fertility, [CO2aq] …) and ii) understand the leverage the Southern Ocean Biological Pump has imposed on atmospheric pCO2 over the last 800 ka (Terminations 1 and 5 in particular). Indeed, coccolithophores are single-celled phytoplankton with unique effect on the oceanic carbon cycle in that they use Dissolved Inorganic Carbon (DIC) for both photosynthesis and calcification. They account for a significant proportion of the marine export production, while the calcite plates (coccoliths) constitute an important component of settling carbonate and ballasting organic particles. Hence, coccolithophores widely contribute to the Biological Carbon Pump (BCP) and impact its strength through changes in their relative abundance and mass that modulate the POC:PIC ratio of sinking biogenic material with consequences for the air-sea partitioning of CO2. Coccolith studies (assemblages and morphometrics) are able thanks to the SYRACO software that provides coccolith abundance and mass, using automated microscope (Leica DM6000B). I complement micropalaeontological observations with profiling XRF data reflecting organic carbon and CaCO3 exports to document high-resolution changes in the POC:PIC ratio of sinking material and by inference the contribution of the BCP to the atmospheric pCO2 changes in the past.
