  1. Summary of results of three-way PERMONAVA of benthic community structure down through the sediment profile with respect to the temporal (three levels: prior to trawling period, 30 and 120 days after intense bottom trawling period) and spatial (three levels: station IP-10, IP-17 and IP-38) variation components (asterisk denotes statistically significant results).
