“…The magnitude of these fluxes is characteristic of each environment because the fluxes are strongly influenced by physical processes such as sediment resuspension, hydrodynamic conditions, sediment granulometry, and seawater temperature (Niencheski and Janhke, 2002;Sakamaki et al, 2006;Grenz et al, 2010). In addition, bioturbation and bio-irrigation (Fanjul et al, 2007), pore water chemistry, and organic matter content contribute significantly to nutrient concentrations (Torres et al, 2009(Torres et al, , 2016Gil et al, 2011Gil et al, , 2014. Torres et al (2016) made the only measurements of benthic fluxes in the northern zone of the SJG and found that sediment consumed DO and nitrate, and released phosphate, silicic acid, and ammonium into the water column.…”
