Collaborative East Antarctic Marine Census (CEAMARC)
Collaborative East Antarctic Marine Census (CEAMARC)
Description Revealed by the powerful lights of a trawl-mounted camera, these elegant solitary sea-squirts, or tunicates, stand half a metre high on the sea bed, 200 m below the surface of the sea off Terre Adélie. They were photographed during the Collaborative East Antarctic Marine Census (CEAMARC) voyage to the Southern Ocean earlier this year. Solitary sea-squirts are fast growing, early colonizers that take advantage of new habitat created by ice bergs scouring the sea bed.
