Sea floor litter monitored using catches of the International Bottom Trawl Survey
AI summary Read the abstract
This report presents seafloor litter monitoring data collected during the 2015 International Bottom Trawl Survey Q1, updating a Dutch program that has tracked marine litter distribution and composition since 2013. The results provide spatial distribution information on seafloor litter across the North Sea as part of European Marine Strategy Framework Directive monitoring.
The Marine Strategy Framework Directive (MSFD) requires from the European Member States to develop programmes of measures to achieve or maintain Good Environmental Status (GES) in European Seas. To be able to evaluate the quality state and trends of the marine waters on a regular basis and the effect of measures, monitoring programs for MSFD descriptors and indicators have been established by the Member states. GES is described by 11 descriptors, and marine litter is one of them. The Dutch monitoring program for this descriptor includes amongst others the collection of data on the presence and distribution on litter on the seafloor. This data should be collected by statutory task fish surveys using standardized bottom trawling gears, as used in the International Bottom Trawl Survey (IBTS). This report presents the results of the seafloor litter monitoring during the IBTS survey of Quarter 1 2015. Seafloor litter data is collected during this survey since 2013, and the new data is presented in perspective of the data collected in previous years. This is done for the composition and the spatial distribution of the seafloor litter from the catch.

AI summary Read the abstract
This report presents seafloor litter monitoring data from Dutch Continental Shelf surveys using bottom trawls, finding plastics comprising 83–87% of all litter and a mean density of 68 items/km² in recent years. The study notes that trawl catchability for litter is estimated below 5%, meaning current estimates substantially undercount true seafloor litter abundance.

Pilot:"collecting Marine ligtter during regular fish surveys
AI summary Read the abstract
This pilot report presents results from monitoring marine litter on the seafloor using regular Dutch IBTS bottom trawl surveys in 2013, with special attention to litter catches and photography. The pilot established improved registration protocols including net inspection, item descriptions, and photos to build a baseline dataset for future temporal trend assessments.
