Dataset gives a baseline for micro- and mesoplastic pollution distribution in 24 beaches along the Latvian coastline (Northern Europe, Baltic states), filling the existing knowledge gap and contributing to the global understanding of microplastic particles presence, transport, and the processes governing its dynamics. We also highlight citizen science as a fundamental tool to support data collection and raise awareness about microplastic pollution, as samples were collected by up to 250 volunteers during organized campaigns (Dimante-Deimantovica et al. 2023).

The dataset contains information regarding marine litter on the Romanian beaches, collected during 3 seasons: winter, spring and autumn. The methodology used is MSFD related and 9 beach sectors were monitored, from Vama Veche (South) to Edighiol (DanuBe Delta Biosphere Reserve).

Seafloor litter collected during 2022 (June-July and October-November) and 2023 (May-June and November) on the Romanian Black Sea shelf.

The methodology used for monitoring has been applied in the Baltic Sea Region since 2011 and is based on the recommendations issued by UNEP/IOC in 2009. It has been further developed, considering the guidelines of HELCOM, OSPAR, and recommendations of the European Commission's JRC Marine Litter working group. Marine beach litter monitoring data were gathered from 15 beaches. Monitoring of 13 sites was conducted three times during the spring, summer, and autumn periods, while two beaches were visited once (in the spring) and then replaced with other beaches (no further marine litter monitoring was carried out at these sites in 2023).

Beach litter monitoring data from the Swedish coastline of Kattegat, the Sound and the Baltic Sea

This dataset includes data of plastic litter collected by citizens and students during 12 campaigns that were organised in Crete (Greece) during the period May 2022 – May 2023. The campaigns were organized within the framework of the NAUTILOS Horizon 2020 project. More specifically the number of plastic litter items per category (using the J code List of the EMODnet Chemistry Thematic Lot n°4) was recorded together with information about the location, date, surface area covered, data contributor and some environmental characteristics (sediment, weather, surroundings).

The dataset contains the results of the monitoring activity in distinct years in Slovenian coastal waters related to contaminants in Sea water, sediments and biota.
