In the United Nations Environment Programme (UNEP) report on the status of international waters (Global International Water Assessment Report, UNEP 2005) the pollution of the Bo-hai Sea was given highest priority in its list of “Issues of Concern” (Table 1, page 61). The main indicators and causes of this pollution were eutrophication, oil spills and suspended sol-ids. Remote sensing offers the possibility of obtaining a synoptic overview of large areas of the Delta region as well as obtaining information on a smaller scale. Such large scale overviews are important for assessing the scale of eutrophication, the presence and development of algal blooms as well as the distribution and dispersion of suspended matter. The aim of WP 3000 is to provide water quality layers from remote sensing data. This includes the mapping of the coastal water near the delta and the mapping of the substances in the water and the analysis of pollution threats and sources.
WP 3000 is structured in three Tasks with following Activities:
Task 3100: Water quality
Task 3200: Pollution threats/hazards
Task 3300: Point and areal sources
