Marine animal forests as useful indicators of entanglement by marine litter ArchiMer
Galgani, Francois; Pham, Christopher K.; Claro, Francoise; Consoli, Pierpaolo.
Entanglement of marine fauna is one of the principal impacts of marine litter, with an incidence that can vary strongly according to regions, the type and the quantity of marine litter. On the seafloor, areas dominated by sessile suspension feeders, such as tropical coral reefs or deep-sea coral and sponge aggregations, have been termed “animal forests” and have a strong potential to monitor the temporal and spatial trends of entanglement by marine litter, especially fishing gears. Several characteristics of these organisms represent advantages while avoiding constraints and bias. Biological constraints and logistical aspects, including tools, are discussed to better define a strategy for supporting long-term evaluation of accumulation and entanglement of...

Marine Litter Distribution and Density in European Seas, from the Shelves to Deep Basins ArchiMer
Pham, Christopher K.; Ramirez-llodra, Eva; Alt, Claudia H. S.; Amaro, Teresa; Bergmann, Melanie; Canals, Miquel; Company, Joan B.; Davies, Jaime; Duineveld, Gerard; Galgani, Francois; Howell, Kerry; Huvenne, Veerle A. I.; Isidro, Eduardo; Jones, Daniel O. B.; Lastras, Galderic; Morato, Telmo; Gomes-pereira, Jose Nuno; Purser, Autun; Stewart, Heather; Tojeira, Ines; Tubau, Xavier; Van Rooij, David; Tyler, Paul A..
Anthropogenic litter is present in all marine habitats, from beaches to the most remote points in the oceans. On the seafloor, marine litter, particularly plastic, can accumulate in high densities with deleterious consequences for its inhabitants. Yet, because of the high cost involved with sampling the seafloor, no large-scale assessment of distribution patterns was available to date. Here, we present data on litter distribution and density collected during 588 video and trawl surveys across 32 sites in European waters. We found litter to be present in the deepest areas and at locations as remote from land as the Charlie-Gibbs Fracture Zone across the Mid-Atlantic Ridge. The highest litter density occurs in submarine canyons, whilst the lowest density can...

Resilience of benthic deep-sea fauna to mining activities ArchiMer
Gollner, Sabine; Kaiser, Stefanie; Menzel, Lena; Jones, Daniel O. B.; Brown, Alastair; Mestre, Nelia C.; Van Oevelen, Dick; Menot, Lenaick; Colaco, Ana; Canals, Miguel; Cuvelier, Daphne; Durden, Jennifer M.; Gebruk, Andrey; Egho, Great A.; Haeckel, Matthias; Marcon, Yann; Mevenkamp, Lisa; Morato, Telmo; Pham, Christopher K.; Purser, Autun; Sanchez-vidal, Anna; Vanreusel, Ann; Vink, Annemiek; Arbizu, Pedro Martinez.
With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyze species’ potential resistance to future mining and perform meta-analyses on population density and diversity recovery after disturbances most similar to mining: volcanic eruptions at vents, fisheries on seamounts, and experiments that mimic nodule mining on abyssal plains. We report wide variation in recovery rates among taxa, size, and mobility of fauna. While...

The quest for seafloor macrolitter: a critical review of background knowledge, current methods and future prospects ArchiMer
Canals, Miquel; Pham, Christopher K.; Bergmann, Melanie; Gutow, Lars; Hanke, Georg; Van Sebille, Erik; Angiolillo, Michela; Buhl-mortensen, Lene; Cau, Alessando; Ioakeimidis, Christos; Kammann, Ulrike; Lundsten, Lonny; Papatheodorou, George; Purser, Autun; Sanchez-vidal, Anna; Schulz, Marcus; Vinci, Matteo; Chiba, Sanae; Galgani, Francois; Langenkämper, Daniel; Möller, Tiia; Nattkemper, Tim W.; Ruiz, Marta; Suikkanen, Sanna; Woodall, Lucy; Fakiris, Elias; Molina Jack, Maria Eugenia; Giorgetti, Alessandra.
The seafloor covers some 70% of the Earth's surface and has been recognized as a major sink for marine litter. Still, litter on the seafloor is the least investigated fraction of marine litter, which is not surprising as most of it lies in the deep sea, i.e. the least explored ecosystem. Although marine litter is considered a major threat for the oceans, monitoring frameworks are still being set up. This paper reviews current knowledge and methods, identifies existing needs, and points to future developments that are required to address the estimation of seafloor macrolitter. It provides background knowledge and conveys the views and thoughts of scientific experts on seafloor marine litter offering a review of monitoring and ocean modeling techniques....
