An aerial view of the Parker River Estuary
Inter-annual variability in ammonium fluxes from sediments in the Upper Parker River Estuary. Years with high ammonium fluxes (such as 1993) correspond to dry years where the salinity rose to over 15 psu. In contrast, ammonium fluxes were low in 1996 when salinities never above 5 psu during the measurement periods.
