CHALLENGE-2: Antarctic Marine Calcifier Samples

Collection of samples of Antarctic marine calcifiers (echinoderms, calcareous algae and bryozoans) at different depths (25m, 15m, 5m and intertidal) by diving or beach sampling for the study of their mineralogical composition and the effect of marine acidification on their structure skeletal. Samples were collected at the following stations: Deception Island, Livingston Island, Fildes Bay, Ronge, Palmer, Rothera, Port Lockroy, Avian Island, Caleta Cierva, and Piñero Island.
