Land-based nutrient inputs to the ocean have been linked increased coastal productivity, subsurface acidification and O 2 loss, even in upwelling systems like Southern California Bight. However, whether eutrophication alters [environment’s] capacity support key taxa has yet be evaluated for this region. Here, we assess impact of land-based on availability aerobic calcifying habitat pelagic using model simulations. We find that acute, lethal conditions are not commonly induced epipelagic surface waters, but sublethal, ecologically relevant changes pervasive. reduce potential calcifier during late summer, when viable is at its seasonal minimum. A region annually recurring compression predicted 30 – 90 km from mainland, southeast Santa Catalina Island. both vertically compressed by, average, 25%, can as much 60%. This effect traced enhanced remineralization organic matter originates coast. These findings suggest effects nutrients restricted chemistry extend multiple ecological economic importance. Considerable uncertainty exists, however, how translates population-level effects.
