Environmental vulnerability winter (BRISK)

A vector grid in 2 x 2 km resolution showing the environmental sensitivity and the underlying themes that have caused the final vulnerability in winter for the Baltic Sea area. This dataset has been produced by COWI (http://www.cowi.dk) for the BRISK project (Sub-regional risk of spill of oil and hazardous substances in the Baltic Sea, http://www.brisk.helcom.fi/). Sensitivity map is based on datasets provided by the BRISK Project Partner organisations. The detailed documentation of what partner provided what data is given in the Annex of the document: 70618-3.1.2.2 Data Collection Report. Field explanations: RS_SR: Rocky shores and stony reefs, Estuaries; Estuaries, Lagoons: Coastal lagoons, Bays: Shallow inlets and bays, Sandbanks: Underwater Sand banks, Beach: Sandy beaches, Seagrass: Sea grass, meadows, Spawning: Spawning area for fish with demersal eggs, Nursery: Nursery areas for fish on shallow water, Off_spawn: Offshore spawning areas for fish with pelagic eggs, Win_Birds: Wintering areas for sea and shore birds, Staging: Staging areas for migrating sea and shore birds, Breeding: Breeding areas for sea and shore birds, Moulting: Moulting areas for sea birds, Mammals: Marine Mammals, Protected: Protected areas, Aquacult:: Fish farms and aqua cultures, Sum: Weighted vulnerability index, Index: Not used Weighted vulnerability index is used to depict vulnerability for the Baltic Sea. Certain parameters have been used to map the environmental sensitivity to oil and each has been weighted for four seasons based on expert judgment. Two alternative sensitivity weighting matrices were also prepared in order to evaluate and validate the results. The sensitivity maps has been combined with the data on oil impact to model environmental damage, and to quantitatively compare the relative efect of the proposed new measures to reduce the risk, impact and damage of oil. Underlaying paramenters used in the vulnerability calculation can be obtained from HELCOM map service under Shipping\Risk Assessment (BRISK)\Environmental parameters -folder.本数据集为分辨率2×2千米的矢量网格，用于呈现波罗的海海域冬季的环境敏感性，以及引发该海域最终冬季脆弱性的潜在影响维度。本数据集由COWI公司（http://www.cowi.dk）为BRISK项目（波罗的海溢油与危险物质泄漏次区域风险，http://www.brisk.helcom.fi/）制作完成。敏感性地图基于BRISK项目合作方提供的数据集生成。各合作方所提供数据的详细说明，收录于文件《70618-3.1.2.2 数据收集报告》的附录中。 字段说明如下： RS_SR：岩岸与石礁（Rocky shores and stony reefs）与河口（Estuaries）； Lagoons：沿海潟湖（Coastal lagoons）； Bays：浅湾与近海小湾（Shallow inlets and bays）； Sandbanks：水下沙洲（Underwater Sand banks）； Beach：沙质海滩（Sandy beaches）； Seagrass：海草甸（Sea grass meadows）； Spawning：底栖卵鱼类产卵场（Spawning area for fish with demersal eggs）； Nursery：浅水鱼类育苗场（Nursery areas for fish on shallow water）； Off_spawn：浮性卵鱼类近海产卵场（Offshore spawning areas for fish with pelagic eggs）； Win_Birds：海鸟与岸鸟越冬地（Wintering areas for sea and shore birds）； Staging：海鸟与岸鸟迁徙中途停歇地（Staging areas for migrating sea and shore birds）； Breeding：海鸟与岸鸟繁殖地（Breeding areas for sea and shore birds）； Moulting：海鸟换羽地（Moulting areas for sea birds）； Mammals：海洋哺乳动物（Marine Mammals）； Protected：保护地（Protected areas）； Aquacult：水产养殖场与水产养殖区（Fish farms and aqua cultures）； Sum：加权脆弱性指数（Weighted vulnerability index）； Index：未使用（Not used）。 加权脆弱性指数用于表征波罗的海的生态脆弱性。本数据集基于专家判断，选取若干参数对油污相关的环境敏感性进行制图，并针对四个季节为各参数赋予权重。此外，为评估与验证结果，研究团队还构建了两套备选敏感性权重矩阵。本敏感性地图已与油污影响数据集结合，用于模拟环境损害，并可定量对比拟实施的新型措施对溢油风险、影响及损害的相对效果。脆弱性计算所用的底层参数，可从波罗的海海洋环境保护委员会（HELCOM）地图服务的「航运风险评估（BRISK）环境参数」文件夹中获取。
