  abstract = {{O}ver half of the total nitrogen, phosphorus, silicate and dissolved organic carbon ({DOC}) loading was discharged from the {W}ile {R}iver into the {T}hau {L}agoon waters within the first five days of what was considered to be the autumn flash flood period. {S}uch loads represented about 8% and 3% of the yearly averaged total nitrogen and phosphorus load in {T}hau {L}agoon, respectively. {A}lthough this event affected >20% of the total lagoon volume, river trace metal loads contributed apparently only weakly to the increase in labile trace metal concentrations in the lagoon surface waters. {D}ifferences between theoretical dilution values and observed values were also noticed for phosphate, silicate and dissolved organic carbon ({DOC}) concentrations. {DOC} losses (10-50%) mainly through flocculation, together with the substantial increases in some metallic contaminants such as {Z}n (from 6 to >30 mu g {L}-1) observed during the flash flood in saline lagoon waters, may have limited the carbon production of bacterial communities. {T}he potential osmotic shock and the increase in turbidity may mainly explain the low phytoplankton {C} turnover rates (average of 0.02 h(-1)) measured in brackish waters (<30) during periods of heavy flood discharge. {T}he dissolved inorganic nitrogen ({DIN}: {NO}3 + {NH}4) enrichment measured 12 days after the flash flood event in saline lagoon surface waters (from 22 to 143 mu g {N} {L}-1) led to a substantial increase in phytoplanktonic {C} production and associated {DIN} uptake rates (from 2.6 to 7.0 mu g {C} {L}-1 h(-1) and from 0.5 to 1.1 mu g {N} {L}-1 h(-1), respectively). {S}ubsequent accumulation in particulate organic carbon and nitrogen was not observed in the area studied during and after the flash flood period, averaging 549 +/- 50 mu g {C} {L}-1 and 168 +/- 9 mu g {N} {L}-1, respectively. {T}his suggests that most of locally produced microbial production was rapidly filtered by oysters contributing to about 13% of the yearly exploited production in the lagoon and/or exported through sedimentation.},
