Floating marine debris, particularly derelict fishing gear, is a hazard to fish, marine mammals, turtles, sea birds, coral reefs, and even human activities. To ameliorate the economic and environmental impact of marine debris, we need to efficiently locate and retrieve dangerous debris at sea. Guided by satellite-derived information, we made four flights north of Hawaii in March and April 2005. During these aerial surveys, we observed over 1800 individual pieces of debris, including 122 derelict fishing nets. The largest debris concentrations were found just north of the North Pacific Transition Zone Chlorophyll Front (TZCF) within the North Pacific Subtropical Convergence Zone (STCZ). Debris densities were significantly correlated with sea-surface temperature (SST), chlorophyll-a concentration (Chla), and the gradient of Chla. A Debris Estimated Likelihood Index (DELI) was developed to predict where high concentrations of debris would be most likely in the North Pacific during spring and early summer.
漂浮的海洋垃圾，尤其是废弃的渔具，对鱼类、海洋哺乳动物、海龟、海鸟、珊瑚礁乃至人类活动都构成危害。为减轻海洋垃圾对经济和环境的影响，我们需要在海上高效定位并回收危险垃圾。在卫星衍生信息的引导下，我们于2005年3月和4月在夏威夷以北进行了四次飞行。在这些空中调查中，我们观察到超过1800个独立的垃圾碎片，包括122个废弃渔网。最大的垃圾聚集区位于北太平洋亚热带辐合带（STCZ）内的北太平洋过渡区叶绿素锋（TZCF）以北。垃圾密度与海表温度（SST）、叶绿素a浓度（Chla）以及Chla梯度显著相关。我们开发了一个垃圾估计可能性指数（DELI），以预测北太平洋春季和初夏最可能出现高浓度垃圾的区域。
