Microplastics in Marine and Estuarine Species From the Coast of Portugal
Pequeno, João; Antunes, Joana; Dhimmer, Viren; Bessa, Filipa; Sobral, PaulaUIDB/ 04292/2020 IT057-18-7252; Microplastics (MP) have been confirmed as emerging pollutants in the marine environment due to their ubiquity, bioavailability, persistence and potential toxicity. This study contributes with valuable data regarding the abundance and characteristics of the MP found in five species collected from Portugal. The mussel Mytilus galloprovincialis (n = 140) was collected from the Tagus...
Quantifying marine macro litter abundance on a sandy beach using unmanned aeria...
Gonçalves, Gil; Andriolo, Umberto; Gonçalves, Luísa; Sobral, Paula; Bessa, FilipaUIDB 00308/2020 REM/30324/2017 IT057-18-7252 UIDB/04292/2020; Unmanned aerial systems (UASs) have recently been proven to be valuable remote sensing tools for detecting marine macro litter (MML), with the potential of supporting pollution monitoring programs on coasts. Very low altitude images, acquired with a low-cost RGB camera onboard a UAS on a sandy beach, were used to characterize the abundance of strande...
