Abstract:Abstract:The land-fast ice and the platelet ice layer off Adélie Land are inhabited by a dense and diversified diatom community.

The two most abundant taxa were… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
