Fishing intensity

The datasets on fishing intensity in the EU waters were created in 2020 by Cogea for the European Marine Observation and Data Network (EMODnet). It is the result of the elaboration of the International Council for the Exploration of the Sea (ICES) data on: i) Spatial distribution of average annual fishing effort (mW fishing hours) in the Greater North Sea and Baltic Sea during 2015-2018, by gear type (Beam trawls, Bottom otter trawls, Bottom seines, Dredges, Pelagic trawls and seines, Static gears). Fishing effort data are only shown for vessels >12 m having vessel monitoring systems (VMS); ii) Average annual subsurface (top) and surface (bottom) disturbance by mobile bottom contacting fishing gear (bottom otter trawls, bottom seines, dredges, beam trawls) in the Greater North Sea and Baltic Sea during 2015-2018, expressed as average swept-area ratios (SAR). Due to data confidentiality issues, VMS/logbook data are anonymized and aggregated in a 0.05x0.05 degree grid prior to submission to ICES, using the C-square geocode system (polygons). The dataset is updated yearly and as soon as new data from ICES are released.

本数据集关于欧盟水域捕鱼强度，由Cogea于2020年创建，旨在为欧洲海洋观测与数据网络（EMODnet）提供支持。该数据集系国际海洋探索理事会（ICES）数据加工的成果，具体包括：一、2015-2018年间，北海及波罗的海区域平均年度捕鱼力度（以马力捕鱼小时计）的空间分布情况，按捕鱼工具类型（包括拖网、底拖网、底围网、挖泥船、远洋拖网及围网、静态工具等）进行细分；仅展示拥有船舶监测系统（VMS）且船体长度超过12米的船舶的捕鱼力度数据；二、2015-2018年间，北海及波罗的海区域由移动式底部接触捕鱼工具（底拖网、底围网、挖泥船、拖网）引起的平均年度水下（表层）及水面（底层）扰动情况，以平均扫海面积比（SAR）进行表达。鉴于数据保密性要求，VMS/日志数据在提交至ICES之前已被匿名化并按0.05x0.05度网格进行汇总，采用C-square地理编码系统（多边形）。该数据集每年更新一次，并在国际海洋探索理事会（ICES）发布新数据后及时更新。
