Description:This report collates the main results delivered in the frame of the CleanAtlantic project, Work package 5.2. Monitoring the presence of marine litter in the marine environment. With this  purpose, an overview of new and improved marine litter monitoring methods for seabed, water surface and coastal compartments in the Atlantic Area is presented. Main findings, gaps on monitoring and research as well as potential improvements and recommendations are highlighted. For some of the topics addressed partners produced fully-dedicated reports. In these cases, links to the original reports are included in the reference section for further information.

Description: This document includes the updated version of the protocol and templates used for monitoring floating macrolitter. These data are recorded along with the monitoring of apex predators. In the frame of the CleanAtlantic project the existent protocol and record sheets were adapted and improved so that they can be used as standard tools for any observer regardless the specificities of the research vessel or institution, and also to facilitate the work of the observers.

Monitoring floating microlitter in offshore waters by manta-trawl (collaboration with iFADO project)

Responsible Partner: IEO
Date: September 2021
Download: Link 
Description: In collaboration with iFADO project 10 samples from Galician offshore waters (NW Iberian Peninsula) were collected by means of a manta-trawl net for microlitter categorization. The results obtained in this work suggest a moderate microlitter density in both coastal and offshore stations. The average of item density for the whole sample collection was 0.0089 ± 0.0091 item/m2 or 0.0446 ± 0.0455 item/m3. Fragments found were abundant in both coastal and offshore stations and were mainly composed by particles with sizes smaller than 1 mm and predominance of green colour.

Assessment between trawl gears baka and GOV for the study of seabed litter

Responsible Partner: IEO
Date: Nov 2020
Download: PDF and DATA
Description: This report aims to assess if there are differences on catchability of seabed litter between the two gears used on the ground fish surveys in the French and Spanish shelves. Baka is the gear used as a sampler in the demersal trawl surveys conducted by the Instituto Español de Oceanografía and the GOV (Grand Overture Vertical) is the standard gear used as a sampler in the ICES area in the demersal trawls surveys carried out by IFREMER and other research institutes in the North of Europe.

Strategy and constraints to support monitoring of Marine Litter Harm: Towards a protocol for the observation of marine organisms entangled/strangled/covered by marine litter during ROV operations

Description: The objective of this report is to review the possible strategies and constraints for monitoring the impact of marine litter in the OSPAR region and to assess the potential of a new indicator of entanglement. Thie report is the result of the research performed within CleanAtlantic, taking advantage of the work done previously by OSPAR, UNEP MAP (Barcelona convention), EU MSFD Technical Group on Marine Litter (TGML) and some EU projects like INDICIT (EU wide), Actions for Marine Protected Areas (AMAre -Mediterranean Sea, https://amare.interreg-med.eu), and Plastic Busters in Marine Protected Areas PBMPA -Mediterranean Sea, https://plasticbustersmpas.interreg-med.eu).

Description: Report describing the App developed by CEFAS. The primary use for the app is for Cefas scientists on board the RV Cefas Endeavour to reduce the use of paper log sheets, streamline the data entry and reduce the time associated with data QC. Therefore, the main focus of the app requirements was based on the Cefas method of seafloor litter logging, which follows the ICES guideline for sampling and the OSPAR categories for seafloor litter, as much of the data is submitted annually to DATRAS.

Marine litter LOC-app

Date: January 2020
Download: Installation Manual, User Manual, Administrator Manual, Annex: Diagram of the data base, APK and server software.
Description: In the framework of CleanAtlantic project, the Technological Institute for the Marine Environment Monitoring of Galicia (INTECMAR) developed the mobile application Marine Litter LOC-app with the objective of facilitate and homogenizate data collection of marine litter pilled-up areas along the coast.
Marine Litter LOC-app allows geolocalizate the zones of accumulation, their characteristics and dimensions, add pictures and comments, as well as collect specific information about the marine litter. Marine Litter LOC- app was created with the purpose of being used during managed monitoring sessions where a coordinator (with the profile of Administrator) must previously choose those sector that will be monitored and must assign each sector to whom will collect data (with the profile of User).
