| During 1985 and 1986, sublittoral communities on hard substrates in the southern Delta area, SW Netherlands, were investigated at 79 stations. The stations were distributed over 20 localities situated in the saline Lake Grevelingen, the Oosterschelde estuary and the SE North Sea. The percentage cover of all sessile organisms were estimated using quadrat sampling techniques; data were processed using cluster analysis. The stations were characterized by the assessment of the most important environmental parameters: available light, hydrodynamics and sediment characteristics. Eight sublittoral communities on hard substrates are described by characteristic and dominant species. Three communities are subdivided into variants on account of differences in... |

| Sponge diversity and community composition in bathyal cold water coral reefs (CWRs) were examined at 500-900 m depth on the southeastern slopes of Rockall Bank and the northwestern slope of Porcupine Bank, to the west of Ireland in 2004 and 2005 with boxcores. A total of 104 boxcore samples, supplemented with 10 trawl/dredge attempts, were analyzed for the presence and abundance of sponges, using microscopical examination of (sub)samples of collected coral branches, and semi-quantitative macroscopic examination. Approximate minimum size of identified and counted sponge individuals was 1 mm. Literature data were added to the Porcupine Bank results to compensate for a less intensive sampling program in that location. Species richness and abundance were... |
