| Abstract |
Epifaunal growth and changing hydrodynamics alter the softsubstrate and macrobenthic community around a foundation. The sediment and macrobenthos was sampled close to a foundation from 2010 to 2012. Observations were most notable on the Southwest side with changes recorded up to 50 meter distance. A decrease in sediment grain size and increase of organic matter content was observed, together with an enriched macrobenthic community with a dominance of hard substrate related species. However, average densities of two bristle worms increased in comparison to the baseline studies, resulting in a young and dynamic macrobenthic community evolving away from the original (Nephtys cirrosa) community. |
