      Geomorphology is a fundamental control on ecological and economic function of estuaries. However, relative to open coasts, there has been little quantification of storm-induced bathymetric change in back-barrier estuaries. ...
    • Quantifying the residence time and flushing characteristics of a shallow, back-barrier estuary : application of hydrodynamic and particle tracking models 

      Defne, Zafer; Ganju, Neil K. (Springer, 2014-09-23)
      Estuarine residence time is a major driver of eutrophication and water quality. Barnegat Bay-Little Egg Harbor (BB-LEH), New Jersey, is a lagoonal back-barrier estuary that is subject to anthropogenic pressures including ...
    • Relationship between water and aragonite barium concentrations in aquaria reared juvenile corals
