Macrozoobenthos data: species composition, abundance (ind/m²), biomass (g/m²) collected during the survey of the National Pilot Monitoring Studies Ukraine (NPMS UA) in the Ukrainian waters (North-Western part of the Black Sea) onboard the R/V "Mare Nigrum" (Romania) in May 2016.

In June 2008 Gaia Research Institute Onlus started a systematic survey of mega-fauna in the Northern Eastern Ionian Sea, in cooperation with the researchers of the Life and System Biology Department of the University of Turin (Italy). GAIA_IONIAN_2008-2018 dataset includes ten years of effort (survey track) and sightings data of marine mammals and marine reptiles collected by experienced marine mammal observers (MMOs) on board of a 12m sailing vessel. MMOs visually inspected both sides (130° angle) of the research vessel, while navigating along random transects. Distance and angle from the track line of each sighting were always recorded.

The Phytoplankton National Monitoring Programme for the identification and enumeration of phytoplanktonic species is an important measurement in the detection of those species which may form a Harmful Algal Bloom event. Where favourable environmental conditions occur, some species may form 'blooms' where high cell densities may cause water discolouration, foaming, mass mortalities of fish, shellfish, invertebrate and benthic organisms through oxygen depletion or produce biotoxins which can accumulate in species of filter feeding bi-valve molluscs, which can cause a variety of human illnesses if consumed when placed on the market for human consumption.
