Macrozoobenthic abundance and biomass from two locations along the southern coast of the Baltic Sea (2019) (ISOFUN)

The dataset contains the quantity of macrozoobenthic organisms collected at eight stations across two sampling locations (ML - open coast, MW - Vistula prodelta) along the southern coast of the Baltic Sea (latitude 54.373 to 54.978, longitude 17.331 to 19.255). Macrofauna samples were collected in three replicates during two research campaigns onboard s/y Oceania in January-February and October 2019 using Van Veen grabs. Samples were sieved over a 0.5 mm mesh size sieve and preserved in formaldehyde solution. Organisms were identified under a stereomicroscope to the lowest possible taxonomic level, counted, and weighed (wet weight). The dataset presents the abundance (number of individuals per square meter) and biomass (grams per square meter) of 30 taxa in total. The dataset is available through IOPAN geonetwork and can be accessed at [doi].
