Barents Sea Marine Litter Monitoring Survey Summary

This survey monitors marine litter in the Barents Sea as part of a joint Norwegian/Russian ecosystem assessment, aiming for good environmental status by 2020. The main goals include exploring the ocean's environment and biology, advising relevant authorities and stakeholders, communicating research results, and developing fishing technology. The survey focuses on aquaculture, coastal areas, oceans, and external influences, with comprehensive spatial coverage and multidisciplinary approaches. The monitoring aims to assess pelagic fish stocks, ecosystem components, and processes, highlighting the need for improved litter registration, detection of degradation products, and knowledge on pollutant effects. The text emphasizes reducing litter discharges, eco-friendly plastics, monitoring standards, and ecosystem health knowledge enhancement. (words: 148)

  1. Monitoring marine litter, a part of the joint Norwegian/Russian ecosystem survey in the Barents Sea Bjørn Einar Grøsvik1, Elena Eriksen1, Tatiana Prokhorova2, Pavel Krivosheya2 • Institute of Marine Research • PINRO, Russland

  3. EU: Goodenvironmental status by 2020 11 descriptors: 1- Biological diversity is maintained. 6 - Sea-floor integrity is at a level that ensures that the structure and functions of the ecosystems. 8 - Concentrations of contaminants are at levels not giving rise to pollution effects. 9 - Contaminants in fish and other seafood for human consumption do not exceed levels established by Community legislation or other relevant standards. 10 - Properties and quantities of marine litter do not cause harm to the coastal and marine environment.

  4. ▶ Main goal • Explore the environment and the biology of the oceans and coasts • Give advice to the Ministry of Fisheries and Coastal Affairs, the Food Safety Authority, the fishing industry and other stakeholders regarding management of the ocean and coast’s biological resources and environment • Communicate the research results • Develop technology for fisheries and catching • IMR has a free and independent role in all scientific questions

  5. ▶ Main focus areas • Aquaculture and coastal areas • Oceans • External influences

  6. Joint Norwegian-Russian Ecosystem survey in the Barents Sea during autumn aimed to obtain capelin, herring, polar cod, blue whiting, shrimps and 0-group abundance estimates/ indices, and monitor the status of some ecosystem components and processes Autumn survey activity August-September: largest ice-free area and minimal stocks migration. Timing is optimal to reflect feeding success and for assessing pelagic fish stocks for assessment and fisheries management advice.

  13. Still there are many questions • The litter registration is dependent of catchability and the amount may be underestimated • We do not register degradation products like microplastic and nanoplastic • To which degree may these be taken up by organisms? • And how it may affect their fitness • We do not know of which other pollutants that adsorbs to different types of plastic

  15. OSPAR: 15 countries together with EU, cooperate to protect the marine environment of the North-East Atlantic. • It started in 1972 with the Oslo Convention against dumping of hazardous waste in the Atlantic and the North Sea. • It was broadened to cover land-based sources and the offshore industry by the Paris Convention of 1974. • These two conventions were unified, up-dated and extended by the 1992 OSPAR Convention. • Annex on biodiversity and ecosystems was adopted in 1998 to cover non-polluting human activities that can adversely affect the sea.

  16. Conclusion • We should work for reducing discharges of litter • Produce more environmental friendly and degradable plastic products • Improve methods and develop standards for monitoring • We need more knowledge on how litter or degradation products may effect ecosystem health
