TRICUSO aims to expand observation capacity in the vast Southern Ocean, home to consortium partner South Atlantic Environmental Research Institute (SAERI). Based in the Falkland Islands, SAERI operates the research vessel Pharos, which will be used in TRICUSO for the deployments of floats and a wave glider, and their flights. We asked CEO Paul Brickle to share some thoughts on the vast waters down under and why TRICUSO is an important project.
