Recent pace of change in human impact on the world's ocean: Cumulative impacts

These are the Cumulative Impact data for publication: 'Recent pace of change in human impact on the world's ocean' (Halpern et al. 2019).
The goal of this project was to describe the patterns and pace of change in cumulative impact on ocean ecosystems due to expanding and increasing intensity of human activities. We combined high resolution, annual data on the intensity of 14 human stressors and their impact on 21 marine ecosystems over 11 years (2003-2013). To determine average annual change in cumulative impacts, we applied a linear regression model to each raster cell.
These data include: Cumulative impacts rasters for 2003 to 2013. These rasters are created using scripts located in the 'impacts' folder of the 'impact_acceleration' Github repository. Average annual change in cumulative impact raster from 2003 to 2013 (i.e., trend). This raster is created using scripts located in the 'trend' folder of the 'impact_acceleration' Github repository. Ecosystem rasters describing the location (1 if present, otherwise NA) of 21 global marine ecosystems. These rasters are the same as used in previous years, with the exception of seaice. The seaice raster was created using a script located in the 'habitats' folder of the 'impact_acceleration' Github repository. A vulnerability matrix describing the vulnerability of each ecosystem to each stressor, with values ranging from 0-4. The impact_acceleration-1.0.zip GitHub repository with the code used to generate, analyze, and visualize data. Data for the individual 14 stressors comprising the cumulative impact are provided in other KNB repositories.
