title: [Distribution of dissolved organic carbon in the Bohai Sea and Yellow Sea in spring].
abstract: Based on the data from cruises that carried out in the Yellow Sea and Bohai Sea from April to May, 2010, the horizontal distribution of DOC was studied. And the influencing factors were preliminary discussed. The results showed that the concentration of DOC in the Yellow Sea and Bohai Sea ranged from 0.96 to 4.71 mg x L(-1) in spring and the average content was 2.27 mg x L(-1). In horizontal distribution, the highest DOC content appeared in the coastal zones both in the south and the north and it tended to decrease toward the offshore in central section on the whole. The highest DOC value was in the nearshore in the western of Bohai Sea and eastern of Shandong Peninsula which was mainly affected by the terrestrial inputs and the offshore current, especially in the nearshore of the western of Bohai Sea, the highest DOC content was 4.71 mg x L(-1). The second highest DOC value was in the Northeast of Yangtze River Estuary which was mainly affected by the Yangtze River Diluted Water (YRDW). However, the low DOC content was mainly found in open seas in the central of the South Yellow Sea, and the DOC value was lower than 1.50 mg x L(-1).
