Chlorophyll-a concentrations are derived from NASA's Sea-viewing Wide Field-of-view Sensor (SeaWiFS). The grid cells are organized by country, and the percentage of change from 1998-2007 is calculated for each cell. Each time series was assessed with a linear regression, and cells with statistically significant trends in chlorophyll-a concentrations are identified. The rows of the table are linked to a sequence grid from the "Indicators of Coastal Water Quality:: Ancillary Data" collection to facilitate the mapping of the trend values for selected countries and areas of interest. The data are processed and compiled by the Columbia University Center for International Earth Science Information Network (CIESIN). Purpose: To provide tabular data on the trends of chlorophyll-a concentration on a pixel by pixel basis for identifying areas with improving, declining, and stable coastal water quality that can provide guidance for decision making in the context of coastal management.

Percentage change from all grid cells showing significant trends were combined in the column SCHANGE, and cells with non-significant trends were given the value -999999. Region assignments followed UN classifications. For more details on procedures, see project documentation available at http://sedac.ciesin.columbia.edu/es/seawifs.html.
