This dataset contains phytoplankton data collected from the Black Sea during cruise 33 of the R/V "Professor Vodyanitskiy", from June 2nd to June 19th 1991.

The data were collected by the IBSS staff at 18 stations in the Black Sea during August 1957 (Cruise 2). This dataset contains abundance data (individuals per liter) for phytoplankton taxa. No additional metadata is available.

The data were collected by the IBSS staff at two diurnal stations in the halistatic region of the Black Sea during April and July 1957. This dataset contains abundance (individuals per liter) and biomass (mg/m³) data for phytoplankton taxa. No additional metadata is available.

The data were collected by the IBSS staff at 18 stations in the Black Sea during November 1957 (Cruise 2). This dataset contains abundance data (individuals per liter) for phytoplankton taxa. No additional metadata is available.

This dataset contains phytoplankton data collected in the Black Sea during the 5th cruise of the R/V "Kiev, from November 11th to December 5th 1995.

The data were collected by the IBSS staff at 18 stations in the North-Western part of the Black Sea during August 1957 (Cruise 1). This dataset contains abundance (individuals per liter) and biomass (mg/m³) data for phytoplankton taxa. No additional metadata is available.

The data were collected by the IBSS staff on vessel T-197 at 13 stations in the Black Sea during April 1952 (Cruise 3). This dataset contains abundance (individuals per liter) and biomass (mg/m³) data for phytoplankton taxa. No additional metadata is available.

The main aim of the dataset is preparing the available data by diversity and distribution of the Black Sea seagrasses, which were collected the scientists from IBSS around Ukranian and Russian coastal zone during last 50 years (1960 - 2009). The data about region, location, sampling equipment are given for each seagrass species. The species diversity is described from 45 transects, 164 stations at 0,3 - 20 m depth. These data are available now for scientists, professionals and they can be used in various purposes.

The dataset contains abundance and biomass data of four species of gelatinous zooplankton (<i>Mnemiopsis leidyi, Beroe ovata, Aurelia aurita, Pleurobrachia pileus</i>) obtained in October 2005 and October - November 2010 (32 stations in October 2005 and 98 stations in October - November 2010) in the Northwestern Black Sea.
