Before the mid-twentieth century, there was no comprehensive narrative about empirical conditions in Swedish seas. Around 1970, this view changed profoundly. In line with growing research and the emergence of ‘the environment’ as a defining concept, conditions in Swedish seas were framed as a ‘narrative of decline’. Marine scientists have since recorded more diverse developments than are described by an overall declensionist narrative. Data show trends of interrupted decline, variability and even recovery, taking place at least partly in response to effective policy and legislation. We suggest that beyond the specialised fields of marine sciences and marine environmental history, the overarching narrative of decline has persisted, paying little attention to local and regional particularities as well as cultural and political dimensions of the marine environment. This overly uniform narrative risks obscuring historical reality and, hence, fails to adequately inform policy and the public about developments and outcomes of interventions in Swedish seas.

瑞典海洋的衰退和多样性：海洋历史，科学和政策中的环境叙事。

在二十世纪中叶以前，没有关于瑞典海经验条件的全面叙述。1970年左右，这种观点发生了深刻的变化。随着研究的不断发展和“环境”这一定义概念的出现，瑞典海域的状况被定义为“衰退的叙述”。自那以后，海洋科学家所记录的发展比整体上的偏执主义叙事所描述的要多样化。数据显示，下降的趋势，可变性甚至恢复的趋势至少部分是由于有效的政策和立法而发生的。我们建议，除了海洋科学和海洋环境史的专业领域外，关于衰落的总体叙述仍然存在，很少关注海洋环境的地方和区域特色以及文化和政治方面。这种过于统一的叙述风险掩盖了历史现实，因此未能向政策和公众充分告知瑞典海域干预措施的发展和结果。
