Benthic fluxes of oxygen and nutrients in sublittoral fine sands in a north-western Mediterranean coastal area

Abstract: Elsevier Sospedra, J.; Falco, S.; Morata T.; Gadea, I.; Rodilla, M. (2015). Benthic fluxes of oxygen and nutrients in sublittoral fine sands in a north-western Mediterranean coastal area. Continental Shelf Research. 97:32-42. doi:10.1016Research. 97:32-42. doi:10. /j.csr.2015 AbstractTraditionally, benthic metabolism in sublittoral permeable sands have not been widely studied, although these sands can have a direct and transcendental impact in coastal ecosystems. This study aims to determine oxygen and nutrie… Show more

“…In our study, the discrepancy between benthic and diffusive fluxes is also due to the lack of data from overnight samples; thus, our calculations only reflect daylight processes without taking into account night respiration and fluxes, which generally differ substantially from the daylight ones. Several authors, in fact, have reported differences in night and day fluxes or during light and dark incubations (Rizzo 1990;Billerbeck et al 2007;De Vittor et al 2012;Dunn et al 2013;Sospedra et al 2015).…”

“…The sampling station (39º 00' 37" N, 00º 09' 19" W) was at a depth of approximately 9 m, where the seabed is composed of 90% fine and very fine sands. These sediments were moderately well sorted with an average grain size value of 0.138 mm (Sospedra et al 2015) and a porosity of approximately 0.47. The community was composed mainly of polychaetes, molluscs, crustaceans and echinoderms between 0.5-20 mm in size.…”

“…These incubations were used to determine DO, ammonium (NH 4 + ), nitrite plus nitrate (NO 2 -+NO 3 -), phosphate (PO 4 3-) and silicic acid (Si(OH) 4 ) fluxes between the sediment and water column in each sampling campaign. Three semi-spherical dark chambers of 40 cm internal diameter, previously used in works in the Gulf of Valencia (Morata et al 2012;Morata et al 2014;Sospedra et al 2015), were placed in the sediment in each sampling campaign. Each chamber had a volume of 16.7 L and covered a sediment surface area of 0.125 m 2 .…”

“…At the surface of the sediment, an excess of organic matter can lead to anoxic conditions (Sospedra et al, 2015). Sediments are also habitat for a great number of Background microorganisms, invertebrates and plants, which are an integral part of the N cycle (Capone et al, 2008).…”
