Sunday 09th April: labour zul !

Onboard the R/V Pourquoi pas? operations and experiences are running day and night.

On TAG site, the fluids/plumes team realized the first yo-yo profile with the CTD-rosette to sample the hydrothermal plume. Jean-Pierre now analyzes in the chemistry lab container the seawater trapped in the sampling bottles. The container is equipped with chromatographs to analyze the methane, CO2… contained in seawater.

Agathe, on her side, analyzes the manganese concentrations.

In the meantime, Charline is processing the bathymetric profiles and backscatter data acquired by the multibeam echosounder, to produce maps of the exploration licence.
