Marine Turtle records for Norfolk Island

This dataset is from a paper by Kellie Pendoley and Margaret Christian (2012) giving a summary of marine turtle records for Norfolk Island, Australia. Nothing has been published in the modern literature on the status of marine turtles at Norfolk Island although their presence has been recognised since 1793 (Fidlon & Ryan 1980). This study brings together all the available published, anecdotal and field survey data on marine turtles at Norfolk Island so that the status of habitat usage could be established. The results confirm the Norfolk Island group is used for foraging by resident adult and juvenile Chelonia mydas (Green) turtles and adult Eretmochelys imbricata (Hawksbill) turtles. The natal beaches for these resident animals are thought to be Melanesian and Polynesian islands to the north and the beaches of north eastern Australia. While juvenile hawksbill turtles have not been recorded foraging at Norfolk Island they are the most common species and age class recorded in the island's strandings data. The confirmation of marine turtles at Norfolk means that any species proposals must include assessment of project impacts on these under Australian Federal legislation and their marine bioregional processes.本数据集源自Kellie Pendoley与Margaret Christian于2012年发表的一篇论文，该论文对澳大利亚诺福克岛的海龟观测记录进行了汇总整理。尽管早在1793年就已有学者确认诺福克岛存在海龟（Fidlon & Ryan 1980），但现代学术文献中从未有关于该海域海龟种群现状的相关研究成果发表。本研究整合了诺福克岛海域海龟所有可获取的已发表资料、轶事记录与实地调查数据，旨在明确该区域海龟的栖息地利用现状。研究结果证实，诺福克岛海域是定居性成年及幼年绿海龟（Chelonia mydas）、成年玳瑁（Eretmochelys imbricata）的觅食场所。据推测，这些定居海龟的产卵滩涂位于北部的美拉尼西亚与波利尼西亚群岛，以及澳大利亚东北部的沿海沙滩。尽管尚未有幼年玳瑁在诺福克岛海域觅食的记录，但该物种的幼年个体却是该岛搁浅数据中最常见的物种与年龄组。诺福克岛海域海龟种群的确认意味着，根据澳大利亚联邦立法及海洋生物区系规程，任何物种相关提案都必须包含对该区域海龟受项目影响的评估内容。
