Fishing Activity for UK Vessels 15m and over 2008 Web Mapping Service (WMS)
收藏资源简介:
This data set provides summaries of fishing activity for UK commercial fishing vessels of 15m and over in length that are deemed to have been fishing within a specified calendar year. These summaries have been categorised into aggregated gear groups that have relevance to their potential impact on the seabed, environment, or biota. Positional data have been extracted from GPS-derived Vessel Monitoring Data. At the highest resolution, equal to 0.05 degree sub-rectangle, the following data items are provided aggregated between vessels using passive gear types or mobile gear types separately: 1. For internal requests for information only, the number of 15m and over vessels involved in each gear type, 2. Time fishing (minutes), 3. From 2011 data onwards, effort in KW Hours (calculated by multiplying the time associated with each VMS report in hours by the engine power of the vessel concerned at the time of the activity) 4. Quantity (tonnes) of live weight fish landed with gear type, 5. Value (sterling) of live weight fish landed with gear type.
本数据集提供指定日历年度内,被认定开展过捕捞作业的15米及以上长度的英国商用捕捞渔船的捕捞活动汇总数据。此类汇总数据已按与海底、生态环境或海洋生物群落潜在影响相关的聚合渔具组别完成分类。位置数据提取自GPS船舶监控系统(Vessel Monitoring System, VMS)采集的数据。在最高分辨率(对应0.05度副矩形网格)下,本数据集分别按被动渔具作业渔船与机动渔具作业渔船两类聚合,提供以下数据项: 1. 仅供内部信息查询:各渔具类型所涉及的15米及以上作业渔船数量 2. 捕捞时长(单位:分钟) 3. 2011年及之后的数据包含作业功率时长(单位:千瓦·时):该指标由每份VMS报告对应的作业时长(小时)乘以作业发生时对应船舶的主机功率计算得出 4. 对应渔具类型的上岸活鱼总重量(单位:吨) 5. 对应渔具类型的上岸活鱼总销售额(单位:英镑)
