    • Submarine groundwater discharge at Kahana Bay, Oahu, 1997-2001: in situ CTD and water chemistry tracer data (NCEI Accession 0011399)

    Metadata Updated: July 28, 2023

    Submarine groundwater discharge (SGD) is neither well understood nor commonly investigated in Hawaii, but it is recognized as a potential pollution source to coastal environments. Between 1997 and 2001, this study located and quantified both total SGD and the terrestrial SGD fraction in Kahana Bay, Oahu. CTD casts were used to profile the water structure and identify potential areas of SGD impact in the bay. Lee-type seepage meters were used to measure SGD rates and collect samples of SGD directly. Radon-222, Si, Cl., and total alkalinity (Ta) were used as natural tracers to measure the terrestrial groundwater fraction within SGD. Nutrient concentrations were also measured to calculate total nutrient fluxes into the bay via SGD. (NODC Accession 0011399)
