Microbes to top predators past data have been gathered as a baseline to a new transdisciplinary sampling programme. The relationship between geodiversity and biodiversity is a key to understanding ecosystems functioning, how benthic communities are structured, and how they might be affected by parameters such as currents, nutrients, sediment chemistry and others. A small remotely operated vehicle (ROV LUMA) has been developed to function down to the deepest zone of the bay (~500m). This project has allowed the continuity of relevant research that investigates signals of global and regional changes in Antarctica. Available metadata from the Brazilian Antarctic Programme (PROANTAR) have been gathered into a format that shall be linked to the Admiralty Bay Benthic Database (ABBED), SCARMarBIN, and the Ocean Biogeography Information System (OBIS) contributing to the Census of Antarctic Marine Life (CAML). The main results have been shown through an Educational and Outreach programme. This has explored the potential to generate relevant didactic and media material, contributing to raising the awareness of Antarctic significance to South America in Brazil.
