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.

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.

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.

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.

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.

Overview of most abundant benthic species and their related densities in the Sluice Dock between 1976 and 1981. The data were digitized by VLIZ from the original report: Thielemans, L.K.H.; Heip, C.H.R.; Van Gansbeke, D. (1982). A summary of benthic studies in the Sluice Dock of Ostend during 1976-1981, in: Heip, C.H.R. et al. (Ed.) (1982). Geconcerteerde Onderzoeksacties Interuniversitaire Actie Oceanologie: eindverslag 3.

In the framework of the OMEX-programme (Ocean Margin Exchange, CEC-MAST II), data were collected on the metazoan meiobenthos along the continental slope of the Goban Spur.

Meiofauna monitoring in the Trieste harbour, Northern Adriatic Sea (Port Authority), 2013 and 2015. In June 2013 and March 2015, sampling was carried out in the harbour of the Trieste port by a KC Haps bottom corer with polycarbonate sample tubes (12.7 cm I.D. with a sample area of 127 cm2). In laboratory, one sediment core was subsampled by means of 3 cut-off plastic syringes (2.7 cm I.D., surface area of 5.72 cm2, 0-10 cm top sediment) in order to obtain three pseudoreplicates for the meiofauna. Meiofaunal organisms (38–1000 m) were extracted from sediment subsamples by sieving each pseudoreplicate and by centrifuging the material retained by a 38 μm mesh net with Ludox HS-40 (density of 1.15–1.18 g cm−3). All meiobenthic organisms were counted and taxonomically classified to the main groups under a stereomicroscope (Olympus SZX12; final magnification of × 32-40)

Nematode and harpacticoid copepod species abundance data are listed as counts per sample. Other available data include sediment granulometry and trace metal concentrations. For a detailed description, see listed publications
