This CD contains part of the data from the Benthos Information system, the database of the Monitor Task-group of the NIOO.
The data included are the available data from 1985 until 2004. All included samples are from the South-Western part of the Netherlands (Delta and coastal area) taken with a Reineck Box-core, a sub-sampling with one or more cores from a box-core, or one or more cores directly taken from the sediment. All samples are taken approximately 30 cm deep into the sediment.
All data is presented in two-types databases (Access and Paradox), each containing two tables. And as an Excel workbook. One table holds all data of the macrobenthos, the other table holds information about the sediment (mean grain-size, silt content). The two tables can be linked through the Sample_id. Sediment data are only available for part of the data. The sediment data are not included in the Excel workbook. Samples with two or more replicates and samples which where divided in several slices are aggregated to one sample.
All actual counted numbers and measured weights are included as well as the calculated density and weights (mg) per square meter. Positions are given in the Dutch system and as geographic coordinates (datum: European 1950 and World 1984). Depth is given in meters below NAP.
Species-names are matched with the European Register of Marine Species as much as possible. Taxonomy and feeding-type are included. All samples whithout any benthic fauna, are added to the databases (not in the Excel-workbook) as entries with empty fields for spesies name and taxonomy. The number, density, AFDW and biomass are set to 0.
DISCLAIMER:
All data on the CD are owned by the Monitor Taskforce of the NIOO-KNAW.
