Nutrient dynamics in the Pomeranian Bay (southern Baltic): Impact of the Oder River outflow

Temporal and spatial variability of phytoplankton photosynthetic characteristics in a southern European estuary (Douro, Portugal)

“…River flow magnitude and water column stratification also influenced nutrient temporal and vertical distribution. In most estuaries, nutrient concentration is often related to river flow magnitude (Jordan et al 1991, Balls 1992, Snow et al 2000, Pastuszak et al 2003. Pereira-Filho et al (2001) reported a tide-nutrient relationship, with a nutrient decrease during the flood and high tide and an increase during the ebb.…”

Role of micrometer sediment particles (SPLITT fractionation) in phosphorus speciation and its recycling in lakes

“…nitrate, phosphate) (Nixon 1995). It may occur naturally but can also be the result of human activity (cultural eutrophication) and it is particularly evident in rivers, shallow lakes, and coastal areas (Csathó et al 2007;Duarte 2009;Nixon 2009;Voss et al 2005;Pastuszak et al 2003). Cultural eutrophication is the process that speeds up natural eutrophication because of human activity, such as, intensive agriculture with excessive use of fertilizers, deforestation, mining, urbanization, industrialization, irrigation, and damming (Howarth 2008;Humborg et al 2006;Meybeck 2004;Stal et al 2003;Carpenter et al 1998;Howarth et al 1996;Nixon et al 1996).…”

Managing Eutrophication in the Szczecin (Oder) Lagoon-Development, Present State and Future Perspectives

“…One problem in the Oder River and Szczecin Lagoon system is that coherent GES targets and MAI do not exist (Pastuszak et al, 2003(Pastuszak et al, , 2005Schernewski et al, 2011;Pastuszak and Witek, 2012a,b). For Small Lagoon, nutrient target threshold concentrations calculated by Brockmann et al (2005), were far too ambitious to be reached even with an highflying river basin management (Schernewski et al, 2008(Schernewski et al, , 2012bNausch et al, 2011).…”
