Pattern of phosphorus forms in a Mediterranean shallow estuary: Effects of flooding events

Floods are responsible for the variation in the concentration of different phosphorus forms contained in the sediment of a small shallow estuary (Palmones River). The maximum differences were observed in the middle estuary, while other stations, placed in the inner and outer parts, showed a less sen...

Description
Summary:Floods are responsible for the variation in the concentration of different phosphorus forms contained in the sediment of a small shallow estuary (Palmones River). The maximum differences were observed in the middle estuary, while other stations, placed in the inner and outer parts, showed a less sensitive response. The apatite forms (AIP) are the major ones. Noticeable changes in the concentration of different phosphorus forms are related with fine grain size sediment. In spite of different responses obtained along the estuary, the results reveal the possibility of using phosphorus concentration as a flood event index, discarding the use of phosphorus speciation for the same purpose.
