On 2-3 November, a workshop and training on Marine Litter monitoring was arranged by CCB in the Gdansk area. The event was arranged in cooperation with MIO-ECSDE and led by Thomais Vlachogianni.
The primary audience was CCB Member Organisations, partners and other NGOs wishing to learn more about Marine Litter Monitoring. There were lectures on basic theory and one actual monitoring event carried out on the beach. The aim was to enable NGOs to gather more data about Marine Litter in the Baltic Sea.
The presentations by Thomais Vlachogianni, MIO-ECSDE held at the workshop are available below:
- The Growing Threat of Marine Litter
- Monitoring Marine Litter on Beaches
- Marine Litter Data Processing
The findings of the survey carried out during the workshop indicate that the majority of items collected are plastic (94%). The top 10 items include cigarette butts and filters (33.6%), cotton bud sticks (20.8%), plastic pieces 2.5cm ><50cm (7.7%), other identifiable plastic/polystyrene pieces (5.2%), plastic caps/lids from drinks (~3.1%), unidentified plastic caps/lids (2.5%), plastic construction waste (2.3%), lolly sticks (2.1%) and foam sponge (2.1%). These are just some preliminary results and definitely more regular surveys are needed to identify the main sources of litter in the area, however these first data indicate that the majority of litter originates from recreational activities on the coast, while the increased presence of cotton bud sticks reveal inputs from sewage discharges either released directly into the marine environment or released into the nearby Vistula River. The calculated density of litter items was 482 items/100 meter stretch or 0.079 items/m2.
