The Global Eutrophication Watch is designed to allow users to perform a preliminary screening of coastal eutrophication potential (CEP) using satellite-derived chlorophyll (CHL) data. This update version (V2) of the App (202209) is bundled with MODIS/Aqua-derived CHL product (Global), SGLI/GCOM-C (250 m resolution dataset around Japan) and the YOC blended CHL dataset (a regional dataset in the Northwest Pacific region). Users are also able to provide a link to their own asset (dataset) of monthly CHL for the App to read.

The Global Eutrophication Watch is designed to allow users to perform a preliminary screening of coastal eutrophication potential (CEP) using satellite-derived chlorophyll (CHL) data. This update version (V2) of the App (202209) is bundled with MODIS/Aqua-derived CHL product (Global), SGLI/GCOM-C (250 m resolution dataset around Japan) and the YOC blended CHL dataset (a regional dataset in the Northwest Pacific region). Users are also able to provide a link to their own asset (dataset) of monthly CHL for the App to read.The manuscript of this App introduces the terms (1) eutrophication potential: waters with both Low (L) or High (H) CHL levels and Increasing (I) trends (LI, HI); (2) eutrophic potential: waters with CHL levels above a given threshold (H); (3) oligotrophication potential: the opposite of eutrophication potential, waters both L or H but with Decreasing (D) CHL levels (LD, HD). LI and HI are of a particular interest as they indicate waters in a process of becoming eutrophic (LI) or a progression of an already eutrophic (HI) water body.
