The seafloor covers some 70% of the Earth’s surface and has been recognised 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 modelling techniques. Knowledge gaps that need
to be tackled, data needs for modelling, and data comparability and harmonisation are also
discussed. In addition, it shows how research on seafloor macrolitter can inform international
protection and c.....
