Using satellite data and spatial models, researchers estimate human influence in the ocean. Darker means more impact.
Two-thirds of the ocean shows increased strain from human-related factors, such as fishing and climate change. And more than three-quarters of coastal waters suffer from climate change and increases in the effects of harmful land-based activities, including pollution. In all, the researchers classified more than 40 percent of the ocean as “heavily impacted” by human activity.
It looks like you can find much of the data used here, under the Cumulative Impact Mapping section.
