The basis for the Kahekili HFMA arises from decadal benthic data (collected by DAR and partners since 1994) that shows that coral cover has been declining since 1999, whereas the abundance of algae has sharply increased, especially the abundance of the invasive algae Acanthophora spicifera. Thus the herbivore fish are more abundant to help combat the algae. Benthic transects were performed to assess the diversity and coverage of algal and urchin species in the Kahekili area in 2008-2009. To address the sources of the algal blooms, a seep sampling device for water chemistry analysis and a macroalgae bio-indicators were used to monitor the nutrient conditions. Fine-scale surveys were made in the Kahekili HFMA and in Kihei in 2008 and 2009. Detection of delta-15 nitrogen levels were made all around Maui in the summer of 2007, every mile in built-up areas and every five miles in remote areas, for a total of 116 sites. To better understand the nitrogen source for the algal blooms and to assess the urchin and algae species and coverage in the Kahekili HFMA. A high ratio of N15 is thought to indicate a source from a well, a low ratio a source from runoff, perhaps from excess fertilizer. 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:0068665 Preview graphic PNG 0068665 NCEI ACCESSION NUMBER 2010-11-17 publication BENTHIC SPECIES BENTHIC SPECIES - TAXA COUNTS BIOCHEMISTRY CORAL EFFLUENT - DISCHARGE IDENTIFIER EFFLUENT - DISCHARGE POINT MACROALGAE NITROGEN SPECIES IDENTIFICATION theme NODC DATA TYPES THESAURUS CHN Analyzer mass spectrometer instrument NODC INSTRUMENT TYPES THESAURUS benthic biological chemical laboratory analyses survey - biological theme NODC OBSERVATION TYPES THESAURUS University of Hawaiʻi at Mānoa dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS University of Hawaiʻi at Mānoa dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS 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.
