海洋垃圾威胁着夏威夷西北群岛的珊瑚礁生态系统。碎片是一种污染物，会缠绕并杀死濒危的夏威夷僧海豹（Monachus schauinslandi）、珊瑚和其他野生动物。我们描述了一个新的多机构的努力，使用潜水员系统地调查和删除两个NWHI在1999年的捕捞渔具。在利西安斯基岛、珀尔环礁和爱马仕环礁清除了14吨废弃渔具，并记录了碎片分布、密度、类型和污染程度。珊瑚礁碎片密度从每平方公里3.4至62.2个不等。拖网是最常见的碎片类型（88%），按重量计算是回收的最大碎片组成部分（35%），其次是单丝刺网（34%）和海线（23%）。大多数碎片回收，72%，有光或没有污垢，这表明碎片可能有很短的海洋环流历史。我们的研究表明，非法渔具对夏威夷群岛的珊瑚礁生态系统构成持续威胁。出版社：Elsevier Science Ltd
Marine debris threatens Northwestern Hawaiian Islands' (NWHI) coral reef ecosystems. Debris, a contaminant, entangles and kills endangered Hawaiian monk seals (Monachus schauinslandi), coral, and other wildlife. We describe a novel multi-agency effort using divers to systematically survey and remove derelict fishing gear from two NWHI in 1999. 14 t of derelict fishing gear were removed and debris distribution, density, type and fouling level documented at Lisianski Island and Pearl and Hermes Atoll. Reef debris density ranged from 3.4 to 62.2 items/ km(2). Trawl netting was the most frequent debris type encountered (88%) and represented the greatest debris component recovered by weight (35%), followed by monofilament gillnet (34%), and maritime line (23%). Most debris recovered, 72%, had light or no fouling, suggesting debris may have short oceanic circulation histories. Our study demonstrates that derelict fishing gear poses a persistent threat to the coral reef ecosystems of the Hawaiian Archipelago. Published by Elsevier Science Ltd.
