Legislations and commitments regulate Baltic Sea status assessments and monitoring. These assessments suffer from monitoring gaps that need prioritization. We used three sources of information; scientific articles, project reports and a stakeholder survey to identify gaps in relation to requirements set by the HELCOM's Baltic Sea Action Plan, the Marine Strategy Framework Directive and the Water Framework Directive. The most frequently mentioned gap was that key requirements are not sufficiently monitored in space and time. Biodiversity monitoring was the category containing most gaps. However, whereas more than half of the gaps in reports related to biodiversity, scientific articles pointed out many gaps in the monitoring of pollution and water quality. An important finding was that the three sources differed notably with respect to which gaps were mentioned most often. Thus, conclusions about gap prioritization for management should be drawn after carefully considering the different viewpoints of scientists and stakeholders.

立法和承诺规范波罗的海状况评估和监测。这些评估受监控需要优先处理的差距的困扰。我们使用了三种信息来源；科学文章，项目报告和利益相关者调查，以找出与HELCOM的《波罗的海行动计划》，《海洋战略框架指令》和《水框架指令》设定的要求之间的差距。最经常提到的差距是，关键需求没有在空间和时间上得到充分监控。生物多样性监测是差距最大的类别。然而，尽管报告中一半以上的差距与生物多样性有关，但科学文章指出了在监测污染和水质方面的许多差距。一个重要的发现是，在最经常提到的差距方面，这三个来源存在显着差异。因此，应在认真考虑科学家和利益相关者的不同观点后得出有关管理缺口优先次序的结论。
