A Modeling Study on Hypoxia Formation in the Bottom Water of the Youngsan River Estuary, Korea

Modelling the marine eutrophication: A review

“… Biogeochemical/biological components Surprisingly, some models of marine eutrophication do not take explicitly into account the nutrients, which are the necessary fuel of excessive biomass production. Several estuarine models are purely physically driven (Peterson and Festa, 1984;Miguez et al, 2001;Li et al, 2003;Fear et al, 2004;Hagy and Murrell, 2007;Steward and Lowe, 2010;Das et al, 2010;Wang et al, 2013;O'Boyle et al, 2015;Beck et al, 2001;Cho et al, 2015;Talke et al, 2009) as well as some coastal zone models (Smith and Hollibaugh, 1989;Legovic, 1997;Helminen et al, 1998;Druon et al, 2004;Pénard et al, 2007;Wan et al, 2012;Chang et al, 2012;Spatharis and Tsirtsis, 2013). "Green tide" models only interested in deleterious effects, i.e.…”

Trophic Structures of Two Contrasting Estuarine Ecosystems With and without a Dike on the Temperate Coast of Korea as Determined by Stable Isotopes

“…The majority of freshwater discharge occurs during July to August by the summer monsoon effect and its discharge is controlled artificially by a dike gate (Sin et al 2012). Hydrological changes from the construction of the dike have resulted in several serious issues in the freshwater and seawater zones, such as the modification of physiochemical properties of the water column and sediments, an increase in nutrients and phytoplankton blooms, hypoxia in bottom water, and changes in biogeochemical processes (Byun et al 2004;Lim et al 2006;Sin et al 2013;Cho et al 2015;Kim et al 2017a). However, despite the importance of understanding carbon flow in anthropogenically altered estuarine systems, relatively little is known about changes in food web structure in the YRE due to the construction of the dike.…”
