The impact of anthropogenic activities on nutrient dynamics in the tropical Wenchanghe and Wenjiaohe Estuary and Lagoon system in East Hainan, China

Nutrient distribution and structure affect the acidification of eutrophic ocean margins: A case study in southwestern coast of the Laizhou Bay, China

“…The analytical precision for TDN, NO 3 -N, NO 2 -N, NH 4 -N, TDP, PO 4 -P and DSi was assessed by multiple analysis of standards and replicates. The precision of the analyses of standard solution was better than 5%, which was consistent with the previous report of Liu et al (2011); all analyses of the samples were carried out in duplicate and the relative standard deviations were b 10%, and the results were expressed as the means. The concentrations of dissolved inorganic nitrogen (DIN) were the sum of NO 3 -N, NO 2 -N and NH 4 -N. The concentrations of dissolved organic nitrogen (DON) and phosphorus (DOP) were estimated by the subtractions of DIN from TDN and PO 4 -P from TDP, respectively.…”

Chemical and spectroscopic characterization of dissolved humic substances in a mangrove-fringed estuary in the eastern coast of Hainan Island, China

“…Qinglan Lagoon is famous for its abundant mangroves, coral reef and fringing reef (Liu et al, 2011), and composed by the internal Bamen Bay and the outer Gaolong Bay (Wang et al, 2006). The Bamen Bay connects to Gaolong Bay through Qinglan tidal inlet and joins to the coastal of South China Sea.…”

“…The Bamen Bay connects to Gaolong Bay through Qinglan tidal inlet and joins to the coastal of South China Sea. The mangrove reserves were established from Wenchang River to the northern part of Bamen Bay and Qinglan tidal inlet (Liu et al, 2011). The dominant mangrove species present are Rhizophora, Avieennia, Lumnitzera, Ceriops, Kandelia, Bruguiera and Sonneratia (Mao et al, 2006).…”

<sup>226</sup>Ra and <sup>228</sup>Ra in the stratified estuary of the Krka River (Adriatic Sea, Croatia): implications for submarine groundwater discharge and its derived nutrients

“…Coastal Zone (Gordon et al, 1996), which has been widely used to evaluate the relative importance of external nutrient inputs versus the physical transports and internal biogeochemical processes within a body of water (e.g., Liu et al, 2009Liu et al, , 2011Wang et al, 2016). Except from river and SGD inputs, atmospheric deposition and wastewater were the other two sources for nutrient input to the KRE surface layer.…”
