摘要: Floating marine debris, particularly derelict fishing gear, is a hazard to fish, mammals, turtles, sea birds, coral reefs, and even human activities. To ameliorate the economic environmental impact of we need efficiently locate retrieve dangerous debris at sea. Guided by satellite-derived information, made four flights north Hawaii in March April 2005. During these aerial surveys, observed over 1800 individual pieces including 122 nets. The largest concentrations were found just North Pacific Transition Zone Chlorophyll Front (TZCF) within Subtropical Convergence (STCZ). Debris densities significantly correlated with sea-surface temperature (SST), chlorophyll-a concentration (Chla), gradient Chla. A Estimated Likelihood Index (DELI) was developed predict where high would be most likely during spring early summer.
