Title

A Note on Very Low-Frequency Salinity Variability in a Broad, Shallow Estuary

Abstract

Abstract Wind stress and river discharge data from the Mobile Bay region indicate significant variance at frequencies below the weather band, but above the semi-annual signal. However, the two records are only very weakly coherent. Two years of salinity data were analyzed in an effort to determine the role that forcing in this band may play in the dynamics of the estuary. These analyses suggest that the salinity response at 50 to 80-day periods is largely due to river discharge. This is also consistent with the estimated 50-day flushing time of Mobile Bay during periods of low discharge. Some wind influence within this band is also apparent.
