Objective	The BIOMIN project is an integrated study on the link between biodiversity/fauna activity and mineralization of organic matter based on a diversified ecological situation (quality of OM and micro/macrofauna). Therefore, the main objective is to study the effects of benthic fauna diversity on processes on bioturbation (bio-irrigation, reworking of sediment), organic matter mineralization processes and the fluxes of the main biogenic elements at the water-sediment interface. In this context, it will involve: 1/ Characterizing the biogeochemical properties of interstitial water and sediment (diagenetic species, nutrients, organic matter, radio elements), 2/ Defining benthic fluxes at the water sediment interface, and 3/ Characterizing the benthic fauna biodiversity and the intensity of bioturbation.

Summary of measurements

-Sampling and measurements in the water column. O2, temperature and salinity (in-situ NKE/Aanderaa SDOT and SPTS type probes), 226Ra (from surface to 3-4 levels), O2, nutrients, metals and CO2 (bottom water samples).
-In situ probes: Two NKE/Aanderaa probes of SDOT (O2, T°C; optode) and SPTS (salinity, T°C, depth) types were mounted on the multitube corer in order to measure O2, temperature and salinity profiles in the water column.
-Radioelement 226Ra: A: surface, 10, 20 (3 levels), E: surface, 25, 50, 70 (4 levels). Water (20 L) was just drained into already rinsed containers and a dose of concentrated HCl added.
-Bottom water sampling: O2, nutrients, metals and CO2.
-Benthic fluxes at the water-sediment interface (O2, NO3-, SRP, Sid, alkalinity, pH): 3/5 closed cores were incubated in the dark at in situ temperature.
-Cutting of cores (1 core ss nitrogen): geochemistry and radoc. Cutting into 20-25 slices: 0-0.5, 0.5-1, 1-2, 2-3, 3-4, 4-5, 5-7, 7-9, 9-11, 11-13, 13-15, 15-17, 17-' cm.
-Ex situ microelectrodes (1 core). Measurements with microelectrodes for high resolution distributions of O2, H2S and pH. No sampling: 50/500 µm.
-Cutting of core samples( 3 cores): MO. Cutting into 12 slices: 0-0.5, 0.5-1, 1-2, 2-3, 3-4, 4-5, 5-7, 7-9, 9-11, 11-13, 13-15, X-X, Y-Y cm (2 deepest layers). Water/Corg content, pigments, amino acids.
-Diversity/biomass of macrofauna: 5 Van Veen grab hauls + 2 Hamon grab hauls (0.25 m2) + sieving.
-Sedimentary structure: SCOPIX and cutting of cores (1 core ss nitrogen): AVS and CH4.
