Macrozoobenthos communities in the area of marine pipeline route at Piltun-Astokhskoye oil field (shelf of northeastern Sakhalin) and their long-term variability
Results of macrozoobenthos surveys (in total 86 stations, 432 sediment samples) in the area of marine pipeline route at Piltun-Astokhskoye oil field in July of 2007-2010 are presented. The sediment samples were collected by van Veen sampler (1-3 samples per site from the area 0.05 m2, 0.11 m2, or 0....

description | Results of macrozoobenthos surveys (in total 86 stations, 432 sediment samples) in the area of marine pipeline route at Piltun-Astokhskoye oil field in July of 2007-2010 are presented. The sediment samples were collected by van Veen sampler (1-3 samples per site from the area 0.05 m2, 0.11 m2, or 0.25 m2) at the depth 0-45 m. The samples were washed by sea water through the sieve with mesh 1 mm, and the residues including macrobenthos were preserved by 4 % buffered formaldehyde for later processing with total identification of macrozoobenthos (species composition, abundance and biomass) in the laboratories of Far-Eastern Research Hydrometeorological Institute and Institute of Marine Biology in Vladivostok, following to standard techniques. The data were analysed using the PRIMER software including multidimensional cluster analysis of samples by hierarchical agglomerative method of group-average linking based on Bray-Curtis similarity of the macrozoobenthos species composition by biomass. In total, 272 species of macrozoobenthos are identified at the surveyed area, with the highest species number for amphipods (86 species) and polychaetes (72 species). Mean total abundance of macrozoobenthos is 26556.4 ± 2660.9 ind/m2, its mean total biomass is 669.7 ± 40.3 g/m2. Cumaceans and amphipod crustaceans are the most numerous groups; sea-urchins, bivalves and cumaceans have the highest biomass. Five benthic communities are defined by cluster analysis. There is concluded that the bottom sediments and depth are the main factors determining the characteristics and distribution patterns of benthic assemblages at present time. |
