Norderney infauna since 1978

Sampling was carried out on board RV "Senckenberg". A 0.2 mm van Veen grab was used for sampling. A single grab was taken at each of the five stations. The samples were sieved over 0.63 mm mesh size and fixed in 4% buffered formaldehyde. After sorting, the organisms were preserved in 70% alcohol. Biomass was determined as ash-free dry weight (AFDW) per mm. Samples were dried for 24h at 85 deg C and burned for 6h at 485 deg C. Biomass data for some taxonomical groups were not available for the years 1989 and 1990. These samples were treated different as these assessments are part of earlier work. Data are available for the 2nd and 3rd quarters from 1978 to 2005, for the 1st quarter from 1978 to 1993 and 2000 to 2005, for the 4th quarter only until 1993.
