“…Typical nitrate accumulation rates in water overlaying sediments range from 20 to 50 mg N/m 2 /d. Mass balance calculations for Pyramid Lake, an oligo-mesotrophic nitrogen-limited terminal lake in western Nevada, showed that internal loading of nitrate from the hypolimnion was around 10 mg N/ m 2 /d and accounted for 70% of annual total inorganic nitrogen loading to the lake (Lebo et al, 1994;Beutel et al, 2001).…”

“…Additional advantages of oxygen over nitrate as a treatment of the anaerobic profundal zone include repression of ammonia release from sediments (Beutel, 2006) and expanded habitat for cold water biota (Moore et al, 1996;Prepas et al, 1997). One final and obvious drawback of nitrate addition is the fact that nitrate is a plant nutrient that can exacerbate eutrophication, particularly in arid and coastal environments (Beutel et al, 2001;Daigle, 2003;Elser et al, 2007).…”

There is renewed interest in the use of nitrate to treat the profundal zone of lakes to inhibit anaerobic biogeochemical processes that result in the degradation of bottom water quality (e.g., sediment phosphorus release, mercury methylation). In this study we used experimental sediment-water interface chambers to quantify the rate of sediment nitrate uptake (SNU) in profundal sediments from Lake Perris, a eutrophic raw water reservoir in Southern California. Deoxygenated chamber water was spiked with nitrate, and nitrate concentration was monitored over time under quiescent conditions, followed by mixed conditions with average water velocities of 1 cm/s. Key findings included: (1) SNU decreased with decreasing nitrate concentration, (2) SNU was higher under mixed versus quiescent conditions by nearly 50%, and (3) nitrate uptake as a function of nitrate concentration followed a conventional sediment oxygen demand model in which nitrate uptake was proportional to the square root of nitrate concentration. The probable mechanism for elevated SNU under mixed conditions was an increased diffusional concentration gradient combined with a decrease in the diffusional boundary layer at the sediment-water interface, both of which enhanced the flux of nitrate from overlaying water into sediment. Managers planning to implement lake nitrate addition should account for induced nitrate demand when determining dosing rates. For example, based on our modeling efforts from this data set, SNU in Lake Perris could range by an order of magnitude, from around 12 mg N/m 2 /d under quiescent, low nitrate conditions (0.1 mg N/l) to around 120 mg N/m 2 /d under mixed, high nitrate conditions (5 mg N/l).

“…The Cyanophyta Nodularia spumigena Mertens (N. spumigena) is a filamentous, heterocystous, nitrogenfixing species known to thrive in brackish and saline waters. There are several reports related to Nodularia bloom in fresh water lake of Turkey (Akcaalan et al, 2009), estuaries of Australia (Blackburn et al, 1996), brackish lakes of Australia and New Zealand (Heresztyn and Nicholson, 1997;Woodward and Shulmeister, 2005), saline lakes and lagoons of USA (Beutel et al, 2001; Galat et al, 1990), Mexico (Falcon et al, 2002), Uruguay (Perez et al, 1999) and Baltic Sea (Sivonen et (Soloviev, 2005). This phenomenon repeated within a short period of time in coastal waters of the southwestern of Caspian Sea in 2009 as reported by the Ecological Aquatic Center of the Caspian Sea (EACCS).…”

Abstract. Despite the increase in phytoplankton population in the Caspian Sea, there is few detail study regarding bloom of some species in the recent years. Previous studies have announced the bloom-forming Cyanophyta Nodularia spumigena Mertens to the Caspian Sea. In this study, we attempt to understand the bloom events that are involved Nodularia spumigena population and environmental parameters in the Iranian coastal water in 2009. The preliminary results suggested that Nodularia spumigena observed in the Caspian Sea in some seasons at different depths but bloom formation starting from middle of summer and reach a maximum in the early of autumn at the surface. Result of this study also showed that phytoplankton assemblage comprised of 46 species after bloom. Bacillariophyta had the highest number of species (17) follow by Pyrrophyta (14), Cyanophyta and Chlorophyta (6) and Euglenophyta (3). But, phytoplankton species of bloom sample is classified in three groups: Cyanophyta, Pyrrophyta and Bacillariophyta which Cyanophyta dominated over the other groups of algae and formed more than 98% and 96% of phytoplankton abundance and biomass, respectively. As of now, the pattern of dominant and frequent species in the Caspian Sea indicated that the health of the water body and aquatic organisms are at risk.

“…N. spumigena blooms have been reported from brackish waters of Australia (Heresztyn and Nicholson, 1997;McGregor et al, 2012), America (Beutel et al, 2001), Africa (Harding et al, 1995), Baltic Sea (Kononen et al, 1993;Mazur and Pliński, 2003;Henriksen, 2005;Mazur-Marzec et al, 2006, 2013Suikkanen et al, 2007, Kankaanpää et al, 2009, and Caspian Sea (Nasrollahzadeh et al, 2011). The mass occurrence of N. spumigena in Lake Burdur was recorded in 2000 for the first time and second for the brackish waters of Turkey (Gülle et al, 2010), the species now the most dominant cyanobacteria species in Lake Burdur.…”
