Using Offshore Wind Farm (OWF) siting in the Baltic Sea as a demonstration case, key issues on developing community data services (CDS) for Blue Growth sectors are explored: e.g. data and product requirements, level of fitness-for-the-purpose and data gaps on the marine CDS for OWF. Through analysing the Blue Growth and marine service value chain as well as user requirements, a list of value-added products has been identified for two user groups: a public group for planning and managing the OWFs and OWF siting sector. Fit-for-the-purpose assessment is carried out to identify data adequacy for OWF siting per key variable in air, water, biota, seabed and human activity areas and per data characteristics, e.g. spatiotemporal coverage, resolution, timeliness, quality and accessibility. Major data gaps lie in observations of wind profiles, currents, sea ice thickness, bottom slope, sedimentation rate, grain size and transport. The results suggest that a community marine data service for OWF siting should be an integrated data portal with open and free data access. It should be a one-stop shop containing both raw data from satellite, in-situ, modelling, socio-economy and OWF sector, but more importantly tailored products which will allow performing feasibility siting on national scale.

以波罗的海的海上风电场（OWF）选址为例，探讨了为Blue Growth行业开发社区数据服务（CDS）的关键问题：例如，数据和产品要求，适用性水平和OWF海洋CDS上的数据缺口。通过分析“蓝色增长”和海洋服务价值链以及用户需求，为两个用户组确定了增值产品清单：一个计划和管理OWF和OWF选址部门的公共组。进行了针对目的的评估，以根据空气，水，生物区，海床和人类活动区域中的关键变量以及数据特征（例如时空覆盖范围，分辨率，及时性，质量和可访问性）来确定OWF选址的数据充分性。主要数据差距在于对风廓线，海流，海冰厚度，底部坡度，沉积速率，粒度和运输。结果表明，面向OWF选址的社区海洋数据服务应该是具有开放和免费数据访问权限的集成数据门户。它应该是一站式商店，既包含来自卫星，现场，建模，社会经济和OWF部门的原始数据，但更重要的是量身定制的产品，将使在全国范围内可以进行可行性研究。
