Observation Campaigns along the Landes Coast

The aim of this project is to develop an eco-physiological model to predict production flow of certain species of planktonic Foraminifera, which are representative of the main ecological system, as well as their habitat (depth, season), from climate forcing. The eco-physiological and geochemical/isotopic characteristics must be determined by the data obtained during cruises. The data from closing nets and sediment traps will be used to evaluate flows from different Foraminifera and the acquisition of their isotope and geochemical signals according to the depth of their habitat and their development cycle. The project is linked to ANR FORCLIM (coordinator L.Labeyrie, LSCE).

Data is organised into two parts : 1/ measurements of physiochemical and biogeochemical parameters in the water column ; inventory of planktonic Foraminifera - 2/ Measurements of biogeochemical parameters and the interface between sediment and water: inventory of benthic Foraminifera fauna. The campaign is connected to the STEEPL Observation Service (Temporal monitoring of benthic and planktonic ecosystems in the Landes plateau) – OSUNA funding (Nantes Angers Sciences of the Universe Observatory).
