Breaking the ice: the introduction of biofouling organisms to Antarctica on vessel hulls
Abstract Few reports exist that describe marine non‐native species in the Southern Ocean and near‐shore waters around the Antarctic continent. Nevertheless, Antarctica's isolated marine communities, which show high levels of endemism, may be vulnerable to invasion by anthropogenically introduce...

Abstract Few reports exist that describe marine non‐native species in the Southern Ocean and near‐shore waters around the Antarctic continent.
