Using acoustics to study the metabolism of marine ecosystems (SEAOX)

Deploying a CTD probe during Sea Grass in Corsica, 2013

SEAOX'18 sea trial 23-30 September 2018

The SEAOX'18 sea trial will take place at the STARESO - Station de Recherches Sous-marines et Oceanographiques in Corsica (France). The experiment is conducted under project SEAOX (PTDC/EEIPRO/ 2598/2014), which aims at using the properties of sound propagation in ocean water as a proxy of the amount of oxygen bubbles to monitor the photosynthetic production of marine plants. See here for a description of a previous experiment in that area carried out in 2011 and 2013 under SENSOCEAN project
