Dissolved organic carbon (DOC) is essential to balance the metabolic demands of North-Atlantic deep-sea sponges
ABSTRACT Sponges are ubiquitous components of various deep-sea habitats, including cold water coral reefs and deep-sea sponge grounds. Despite being surrounded by oligotrophic waters, these ecosystems are known to be hotspots of biodiversity and carbon cycling. To assess the role of sponges in the c...
