Title: Marine litter LOC-app
Responsible Partner: INTECMAR
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).



Title: Microplastic ingestion by pelagic and benthic fish and diet composition: A case study in the NW Iberian shelf
Responsible Partner: IEO Vigo
Date: March 2021

Description: This study evaluated the incidence of microplastics in the digestive tract contents of four fish species: Engraulis encrasicolus, Sardina pilchardus, Callionymus lyra and Mullus surmuletus. Alkaline digestion (10% KOH) was used to degrade the organic matter. The percentage of fish with microplastics was 78% (88% fibres, 12% fragments). The main types of polymers identified by Raman spectroscopy were polyethylene and polypropylene. The diet of the four species was also studied and two feeding types were determined: plankton-feeders and benthic-feeders. The effect of a set of biological variables (Length, Fullness index, Fulton’s condition factor and Feeding type) on the number and size of microplastics ingested was studied using Generalised Additive Models (GAMs). A significant increase in the number of microplastics with increasing length was observed. No significant effect of trophic variables (fullness index and feeding type) on the number and size of microplastics was found.


Title: Ingestion of plastic debris (macro and micro) by longnose lancetfish (Alepisaurus ferox) in the North Atlantic Ocean
Responsible Partner: IEO Vigo
Date: January 2020

Description: This study evaluates the ingestion of plastic marine debris (macro and micro plastics) by a piscivorous predator, Alepisaurus ferox Lowe (1833). A total of 27 specimens were captured in 2015 and 2016 in the North Atlantic (around 34º–36º N and 10º–16º W) and their stomachs were dissected and inspected for plastic elements. Macroplastic particles were found in 37% of fish, with an average weight of 0.46 ± 1.14 g with film being the most abundant category (60%). The main polymers characterized were Polypropylene (PP) and Polyethylene (PE). Microplastics were found in 74% of the stomachs, with item values per individual ranging from 0 to 16, with an average value of 4.7 ± 4.8 items per stomach. Only microfibers and fragments were observed, with microfibers (85 %) being the dominant type.


Title: Will COVID-19 Containment and Treatment Measures Drive Shifts in Marine Litter Pollution?
Responsible Partner: ARDITI, OSPAR and DRAAC
Date: August 2020
Download: Link to publication
Description: This opinion article underlines the authors’ concern about the mass use of disposable masks and other personal protective equipment without a concerted strategy for their recycling, which could result in an increase of litter entering the marine ecosystems. The paper intends to act as a call on policy makers and international organizations to maintain their goals in plastic reduction in the oceans and to adapt their litter monitoring programs so as to identify litter from the use and disposal of personal protective equipment.

Title: Monitoring the presence of marine litter in the marine environment: potential of remote sensing
Responsible Partner: CEFAS
Date: October 2019
Download: Report
Description: This report focus on the potential of satellites to develop and improve monitoring methods of marine litter. More specifically, it assess the feasibility of Sentinel 2 data in identifying plastic litter hotspots; investigates what the spectral ranges of polymers using Sentinel 2 data are; and proposes a method of plastic litter hotspots identification.
