| Following a preliminary mapping survey using a combination of acoustic techniques, spatial patterns of sedimentologic and biological characteristics of the Bay of Douarnenez were studied in 2001 from a series of grab samples and underwater video recording aiming at calibrate the acoustic facies of the bottom and at characterized them from a biological point of view. Results obtained from community structure analysis showed that four principal ecological groups dominate : The coarse sands community with Branchiostoma lanceolatum, Glycymeris glycymeris and Glycera lapidum, the fine to medium sand community with Nephtys cirrosa, Ophelia borealis and Gastrosaccus spinifer, the mixed muddy sand and gravel community with Amphiura filiformis, Edwardsia sp. and... |
