The Antarctic Free Ocean Carbon Enrichment (antFOCE) underwater and surface experimental system was deployed over the last few weeks with a coordinated effort involving the dive team, technicians and station support. Four experimental chambers are now in place on the sea floor, each with 40 metres of ducting and an inlet and thrusters tube attached.

Each duct was lowered through a hole in the sea ice and suspended from the underside of the ice by a system of rope lines lowered through smaller drill holes. Once suspended from under the sea ice, divers used their communications system (divers can talk to each other and the dive supervisor on the surface) to coordinate the lowering of the duct into place on the sea floor (around 12 — 14 metres deep) where each duct was attached to a chamber.
