Regime shifts in the marine environment have recently received much attention. To date, however, few large-scale meta-analyses have been carried out due to insufficient data coverage and integration between sustained observational datasets because of diverse methodologies used in data collection, recording and archival. Here we review the available data on regime shifts globally, followed by a review of current and planned policies with relevance to regime shifts. We then focus on the North and Baltic Seas, providing examples of existing efforts for data integration in the MarBEF Network of Excellence. Existing gaps in data coverage are identified, and the added value from meta-analyses of multiple datasets demonstrated using examples from the MarBEF integrated data project LargeNet. We discuss whether these efforts are addressing current policy needs and close with recommendations for future integrated data networks to increase our ability to understand, identify and predict recent and future regime shifts.
近年来，海洋环境中的生态系统变迁受到了广泛关注。然而，由于数据收集、记录和归档所采用的方法多样，加之持续观测数据集之间缺乏充分的数据覆盖和整合，目前为止，仅有少数大型元分析得以开展。本文首先对全球范围内现有的生态系统变迁数据进行了综述，随后对与生态系统变迁相关的现行政策和计划政策进行了综述。接着，本文聚焦于北海和波罗的海，以 MarBEF 卓越网络中现有的数据整合工作为例，介绍了数据整合的现有努力。本文还确定了数据覆盖方面的现有差距，并通过 MarBEF 综合数据项目 LargeNet 的示例展示了来自多个数据集的元分析的附加值。最后，本文讨论了这些努力是否满足当前政策需求，并就未来的综合数据网络提出了建议，以提高我们理解、识别和预测近期和未来生态系统变迁的能力。
