为了实施基于生态系统的管理、海洋保护区和海洋分区，需要对所有人类利用海洋的空间模式及其累积影响进行定量评估。在这里，我们应用开发的方法来映射全球累积影响的加州电流使用更全面，更高质量的数据为25个人类活动和19个海洋生态系统。该分析指出了加州海流中最需要保护和缓解威胁的地方，并揭示了人口密度高的沿海生态系统以及俄勒冈州和华盛顿外的大陆架受到的影响最严重，气候变化是最大的威胁，多种威胁的影响无处不在。值得注意的是，这些结果在空间上与该区域的全球结果高度相关（R-2 = 0.92），这表明全球模型为没有当地数据或资源的地区提供了指导，以进行类似的区域尺度分析。
Quantitative assessment of the spatial patterns of all human uses of the oceans and their cumulative effects is needed for implementing ecosystem-based management, marine protected areas, and ocean zoning. Here, we apply methods developed to map cumulative impacts globally to the California Current using more comprehensive and higher-quality data for 25 human activities and 19 marine ecosystems. This analysis indicates where protection and threat mitigation are most needed in the California Current and reveals that coastal ecosystems near high human population density and the continental shelves off Oregon and Washington are the most heavily impacted, climate change is the top threat, and impacts from multiple threats are ubiquitous. Remarkably, these results were highly spatially correlated with the global results for this region (R-2 = 0.92), suggesting that the global model provides guidance to areas without local data or resources to conduct similar regional-scale analyses.
