This map represents 762 coastal areas impacted by eutrophication and/or hypoxia. There are 479 sites identified as experiencing hypoxia, 55 sites that once experienced hypoxia but are now improving, and 228 sites that experience other symptoms of eutrophication, including algal blooms, species loss, and impacts to coral reef assemblages. These data were compiled using a literature search conducted by Dr. Robert Diaz of VIMS and WRI staff. Because this map depends on available data, geographic areas with more data availability (such as the United States) may show relatively more problem areas compared to areas with less data.
We need your help to ensure that this dataset is accurate and up to date. Please let us know if we are missing a site, or if you believe a site on the map is misclassified. We look forward to hearing your comments.
