These data describe counts of macrobenthic infauna (with associated station metadata) taken from sediment samples collected at sites in the Tyne, Thames and Shoreham, UK from 2000 to 2006. For selected samples, wet biomass data is also included per taxon. The samples from the Shoreham site were collected across an aggregate extraction area over 4 years with the aim to test several habitat mapping techniques by documenting the presence of different faunal levels across the area. The samples collected at the Tyne and Thames were initiated at former sewage sludge disposal sites. Cefas conducted annual sampling in these areas during and post cessation of sewage disposal after January 1999 to monitor the benthic macrofauna community.

Species composition, abundance and biomass of the phytoplankton at selected depths from the seabed to the surface.

Biomass and abundance of western Baltic Sea benthic meio and macrofauna (all fauna >6 um sieve). Individual measures of body size, from Bornholm to Lulea. Only from Swedish and Danish waters.

Species composition, abundance and biomasss of zooplankton at selected layers from the seabed to the surface. Approximately 100 species included in the database.

The database contains abundance of main meiofaunal groups and of harpacticoid copepods separately. There are also data present from a recolonisation study.

Abundance (individuals/m2) and biomass (g/m2) of macrozoobenthic taxa from seagrass meadows along the Southern Bulgarian Black Sea coast (Burgas Bay), collected during field surveys of IBER-BAS in 2013-2014 as part of project PERSEUS. Due to the sampling method (hand corer), the dataset represents the infauna associated with the seagrasses. The dataset also contains measurements of several environmental parameters at the stations: sediment grain size (% gravel, sand, and silt/clay); sediment moisture content (%) and total organic matter (% loss on ignition); temperature and salinity of the water.
