From 1971 onwards, seasonal data (at least twice a year) of the above mentioned parameters are obtained from subsamples (10 cm2) out of the box-core samples of the Southern Bight of the North Sea with detailed information on the Belgian coastal area. Species lists are complete for nematodes, and partially complete for the copepods. Other meiofauna data are not available on the species level. From 1979 onwards, similar data are available for the Western Scheldt. Kenyan mangroves: species lists of nematodes from mangrove areas for Sep 1989, Sep 1990. Greenland (Disko Island) : species list of nematodes from July 1990. Antarctica : meiobenthic taxa, species list of nematodes from Jan 1989 (EPOS leg III expedition). .
