Ana Martins and Catharina Pieper, researchers from the Department of Oceanography and Fisheries (University of the Azores) are two of the co-authors of the paper “Toward the Integrated Marine Debris Observing System”.

The paper acknowledges that existing ocean circulation models are not able to accurately simulate drift of debris because of its complex hydrodynamics. In this paper the discussion of the structure of the future integrated marine debris observing system (IMDOS) that is required to provide long-term monitoring of the state of this anthropogenic pollution and support operational activities to mitigate impacts on the ecosystem and on the safety of maritime activity is considered. The proposed observing system integrates remote sensing and in situ observations. Also, models are used to optimize the design of the system and, in turn, they will be gradually improved using the products of the system. Remote sensing technologies will provide spatially coherent coverage and consistent surveying time series at local to global scale. Optical sensors, including high-resolution imaging, multi- and hyperspectral, fluorescence, and Raman technologies, as well as SAR will be used to measure different types of debris.
