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.

Long-term monitoring of chlorophyll-a, ammonium, dissolved total nitrogen, nitrate, nitrite and phosphate concentrations in the water column at Sozopol, Bulgaria (2013-2021).

Abundance (individuals/m2) and biomass (g/m2) of macrozoobenthic taxa at soft-bottom stations along the Southern Bulgarian Black Sea coast (Burgas Bay), collected during field surveys of IBER-BAS in 2013-2014 as part of project PERSEUS. 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, salinity and dissolved oxygen in the water column and near the bottom.
