Controls on the processing and fate of terrestrially-derived organic carbon in aquatic ecosystems: synthesis of special issue

摘要

This special issue brought together a complementary set ofudstudies describing the range of processes affecting theudcycling and fate of terrigenous organic matter withinudaquatic systems. It focuses in particular on headwaterudstreams, and on peat catchments as major global sources ofudfreshwater dissolved organic matter and of particulate organic matter in areas of peat erosion. This work is placed within the wider context of processesudoccurring in forested and agricultural headwaters, largerudriver systems and estuaries, and in a policy context inudrelation to national-scale carbon fluxes, the treatment ofudorganic matter in drinking water supplies and the inclusionudof aquatic carbon in international greenhouse gasudaccounting.
