Attributes of communities-at-sea, including the size of servicesheds and climate change risk exposure scores, determined from Vessel Trip Report (VTR) data for commercial fishing trips from 1996 to 2014

<p>Communities-at-sea are peer-groups of vessels which share a gear type and are associated with a particular port (e.g., vessels from New Bedford, MA that use gillnets). For vessels using trawl gear, small and large trawlers are considered separate communities according to vessel length (&lt;&gt; 65 feet). We used Vessel Trip Report (VTR) data for commercial fishing trips from 1996 to 2014, as reported by vessel captains, to determine the at-sea \"servicesheds\" or customary fishing grounds of communities.</p>海上作业群组指共享同一渔具类型、隶属于特定港口的渔船同质群组（例如来自美国马萨诸塞州新贝德福德港、使用刺网的渔船）。对于使用拖网渔具的渔船，依据船长尺寸以65英尺为界，将小型与大型拖网渔船划分为不同的海上作业群组。本研究采用1996年至2014年由渔船船长上报的商业捕鱼航程渔船行程报告（Vessel Trip Report, VTR）数据，以确定各海上作业群组的海上‘服务域’或传统作业渔场。
