Length and widt data were collected for 4233 nematode individuals. For each genus, the feeding type was determined (when possible). Samples were taken at depths ranging from 160 m to 1220 m, in two replicates.

This dataset, compiled in the framework of a Msc thesis, contains information on the meiobenthic communities of six different stations in the Southern Bight of the North Sea, together with information on a number of environmental parameters.

Meiobenthos data, as well as data on water parameters and sediment parameters, was gathered at 8 stations along the Turkish Black Sea coast, during 12 sampling events, at 2 depths (3 and 10m). All data is restricted.

This dataset is the result of a laboratory experiment to determine the response of benthic nematode communities to different pollutants in various doses and in two sediment types. The Lynher estuary is characterised by muddy sediments, whereas the Exe estuary is sandy.

Experimental data using benthic mesocosm facility at Solbergstrand, Norway. - 4 box cores containing four cages. Cages= two replicates of two densities of Brissopsis. Samples taken inside cages. Samples taken outside cages = controls

This dataset was the first of its kind, making use of simplified ecosystem models or so-called microcosms to examine the effects of different frequencies of physical disturbances on meiofaunal communities.

The Darwin mounds area was sampled to investigate the importance of local-scale topographic features and small-scale biogenic structures in influencing the density and diversity of the associated meiobenthic communities and nematodes in particular.

Experimental data - sediment from Fal estuary (field-contaminated with heavy metals) seeded with meiofauna from Lynher estuary in microcosms

Experimental data - nematode data from microcosms dosed with three levels of contaminants (Cu, Zn, Cd,Pb) plus controls and initial field samples.

This dataset was compiled in the framework of a PhD thesis. It focuses on the copepod density, diversity and community structure in relation to sediment characteristics and depth for one sandbank.
