Benthos, density
Description:
Spatial distribution of selected macrozoobenthic species in the German Bight.
Data source:
Data from environmental impact assessments (EIA) under the permit procedures of the Federal Maritime and Hydrographic Agency (BSH) in the North Sea EEZ and research data of the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research; time period: 1997 to 2011, mainly spring and autumn data (EIA data), but also summer and winter data (AWI data)
Sampling standards:
Data of EIAs follow the standard investigation concept StUK 1-3 (BSH 2007), AWI data collected in accordance with the ICES sampling standard (Rumohr 1999).
Sampling gears:
mainly van Veen grabs (0.1 m², 30-95 kg), few stations by box corer (0.1 m², 160 kg), Nephrops norvegicus and Goneplax rhomboides sampled by beam trawl and dredge (1-3 m width)
Sampling:
1-3 replicates per station, fixation in 4 % buffered formalin seawater solution, dredge and beam-trawl data recorded on board or subsamples frozen stored, abundance and biomass (g wet weight) per species
Data analysis:
science information system of benthic invertebrate data, examination of quality and plausibility, data harmonisation, product computation by AWI
Product description:
Grid: 5x5 km² for grab data, 10x10 km² for data on N. norvegicus and G. rhomboides from beam trawl and dredge hauls; available selectable parameter: number of stations, minimum, maximum, mean, median and standard deviation of density (m-²) per species; classification method: natural jenks (Jenks Caspall algorithm), Note: The products contain a different classification of species density!
Note: Please regard different value ranges!
