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. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0011399 Preview graphic PNG 0011399 NCEI ACCESSION NUMBER 2006-12-13 publication AMMONIUM (NH4) CHLORINITY Methane (CH4) NITRATE NITROGEN NITROGEN - ORGANIC phosphate PHOSPHATE - TOTAL PHOSPHORUS - ORGANIC SALINITY Silicon total alkalinity WATER TEMPERATURE theme NODC DATA TYPES THESAURUS CTD instrument NODC INSTRUMENT TYPES THESAURUS chemical physical theme NODC OBSERVATION TYPES THESAURUS University of Hawaiʻi at Mānoa URS Corporation dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS URS Corporation dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Coastal Waters of Hawaii Hawaiian Islands Humpback Whale National Marine Sanctuary North Pacific Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
