The characteristics and behavior of DFG at sea have been described using a range of approaches from anecdotal observations to quantitative methods. Many observations of pelagic DFG have been anecdotal, and data have not been systematically collected on net size, composition, changes in physical properties, or
other attributes. Some information on the characteristics of DFG collected in nearshore environments is known, and these data may inform our understanding of the characteristics and behavior of pelagic DFG. however, physical abrasion and photodegradation of DFG may differ in pelagic and nearshore environments.
