| Session Description |
There is a growing recognition that the submarine discharge of fresh, brackish, and marine groundwater (SGD) into coastal oceans is as important as river discharge in many areas of the ocean. Since most bio-limiting constituents (i.e., N, P, Si) are very highly enriched in coastal groundwater relative to surface water in general, the relative contribution of SGD versus river runoff may inevitably influence the coastal biogeochemistry and ecosystem. For example, the pollution with nutrients in coastal groundwater or surface water results in red tides and benthic eutrophication in some areas of the coastal ocean. Therefore, in this session we include presentation of any studies on (1) the evaluation of the magnitude or mechanisms of SGD or river runoff, (2) coastal biogeochemistry associated with river runoffs or SGD, or (3) the biogeochemical consequences of land-ocean interactions in the coastal ocean. |
