The gut content (dry mass and organic matter fraction) of three antarctic ascidians (Corella antarctica, Cnemidocarpa verrucosa, and Molgula pedunculata) under different sedimentation regimes were estimated together with mantel glycogen content. Samples were taken by scuba diving at 20 m depth at three different stations inside Potter Cove (South Shetlands, Antarctica): Inner Station (62º13'23.6''S; 58º38'41''W), Middle Station (62º13'54''S; 58º40'06''W), and Outer Station (62º14'10''S; 58º42'48''W) during austral February 2011.
