Litter on the seafloor along the African coast and in the Bay of Bengal based on trawl bycatches from 2011 to 2020
We present the occurrence of seafloor litter on the coast of Africa and in the Bay of Bengal based on records from the EAF-NANSEN Programme in 2011 to 2020. Litter bycatch records from 534 bottom trawls were standardized to km2 before analysis. Three percent of the records indicated areas of high li...
