The phytoplankton dataset includes samples collected from shallow to shelf Romanian waters, in the period 1975 - 1980, from March to November; there is no similar frequency each year. Dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa.

The phytoplankton dataset includes samples collected from shallow to shelf Romanian waters, in the period 1961 - 1970, from March to November; there is no similar frequency each year. Dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa.

The phytoplankton dataset includes samples collected from shallow to shelf Romanian waters, in the period 1981 - 1990, from February to November; there is no similar frequency each year. Dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa.

The macrozoobentos dataset includes a number of 56 samples collected on the Longitudinal profiles (L) of the Romanian littoral between 8 m to 42m depths. Van Veen grab with a sampling area of 1/20 m2 was employed as a macrozoobenthos sampler. One replicate was collected at every station. Sampling was done in autumn period (September, October).The samples have been analyzed qualitative (number of species) and quantitative (densities and biomasses). The macroinvertebrates have been identified at species level.

Phytoplankton data collected in the Black Sea between 1956 and 1960 and processed by Hilarius Skolka and Nicolae Bodeanu. This dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa. Samples were taken by 1L Nansen bottle at standard depths. The standard sedimentation technique for samples preparation (Morozova-Vodianitkaia, 1954) was used.

The macrozoobenthos dataset includes a number of 243 samples collected in the Northern part of the Romanian littoral between Sulina and Chituc from 10 m to 57m depths. Van Veen grab with a sampling area of 0.05 m2 was employed as a macrozoobenthos sampler. One replicate was collected at every station. Sampling was done in spring, summer and autumn mounths.The samples have been analyzed qualitative (number of species) and quantitative (densities and biomasses). The macroinvertebrates have been identified at species level. Dataset contains abundance data (ind/m2) and biomass (g/m2). The macroinvertebrates have been identified at species level.

The macrozoobentos dataset includes a number of 234 samples collected in the East Constanta sector of the Romanian marine waters from five standard stations (Station 1-5) between 14 m to 55m depths. Van Veen grab with a sampling area of 1/20 m2 was employed as a macrozoobenthos sampler. One replicate was collected at every station. Sampling was done in winter, spring, summer and autumn mounths.The samples have been analyzed qualitative (number of species) and quantitative (densities and biomasses). The macroinvertebrates have been identified at species level.

The macrozoobentos dataset includes a number of 347 samples collected in the Northern part of the Romanian littoral between Sulina and Chituc from 5 m to 52m depths. Van Veen grab with a sampling area of 1/20 m2 was employed as a macrozoobenthos sampler. One replicate was collected at every station. Sampling was done in spring, summer and autumn mounths.The samples have been analyzed qualitative (number of species) and quantitative (densities and biomasses). The macroinvertebrates have been identified at species level.

The present database represents the situation of strandings of dolphins along the Romanian coast during 2010 and 2012. The data were collected from the entire Romanian coast, from Sulina to Vama Veche.

Collecting data regarding sightings of the Black Sea cetacean at the Romanian coast.
