Abstract:
The Change in Chlorophyll-a Concentrations 1998-2007 component of the Indicators of Coastal Water Quality Collection represents a tabular time series of the chlorophyll-a concentrations for each grid cell, derived from the "Indicators of Coastal Water Quality:: Annual Chlorophyll-a Concentration 1998-2007" data set. 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.

Process Description:
Yearly concentrations contained in "Indicators of Coastal Water Quality:: Annual Chlorophyll-a Concentration 1998-2007" were combined into a time series table, and the following statistics were calculated to characterize trends over time: slope of regression of chlorophyll-a concentration on year (SLOPE), r-square values of regression (R2), change in percent between 1998 and 2007 (expressed relative to 1998) (CHANGE), and p-value of regression (P). 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.
