Water quality data from the State of Hawaii Department of Health in Hawaiian waters from 1973 to 2006

공공데이터포털

Water quality data from were collected by the Monitoring Section of the State of Hawaii, Department of Health. Data were obtained from 373 state-wide coastal stations employing well-established instruments and methodologies. This dataset spans 1973-2006. Parameters include temperature, salinity, conductivity, dissolved oxygen, percent saturation of oxygen, pH, turbidity, oxidation-reduction potential, and concentration of fecal coliforms.

Near shore water chemistry data from Island of Hawaii and Lanai 1988-2011 (NCEI Accession 0104398)

공공데이터포털

This data set contains coastal water quality parameters as measured at seven shoreline locations on the west side of the Island of Hawaii and one site on Lanai, Hawaii during 1988-2011. Each location had over 20 sub-sites for sampling. Most were sampled roughly 4 times per year though some only once annually and other years with as many as 11 observational visits. The water quality data comprise 14 parameters and were collected using well-established instruments and methodologies. Parameters are aspects of water chemistry including turbidity. This set does not include measurements of bacteria. The data are stored in spreadsheets of the same format, with one file per location.

Water quality data collected from Maui, Lanai, and Hawaii, 1989-2005 (NCEI Accession 0031350)

공공데이터포털

Transects were made on three Hawaiian islands (Maui, Lanai, and Hawaii) in nine areas to collect in situ water quality measurements. Each area has several survey transects from the shallows seaward. The project was lead by Dr. Richard Brock of the University of Hawaii Sea Grant College Program with sponsorship from the Monitoring Section of the State of Hawaii, Department of Health, Clean Water Branch. Well-established instruments and methodologies were used. Most of the data were during 2001 - 2005, however, some areas have data back to 1989 and several to the mid-1990's. Transects were mostly repeated quarterly to semi-annually. Data is provided in spreadsheet format.

Synoptic Bi-monthly and storm response water quality sampling in Southern Kaneohe Bay, Hawaii, from November 2007 - April 2009 (NCEI Accession 0062644)

공공데이터포털

Synoptic sampling including water column profiles and collected surface water samples was conducted on a bi-monthly basis throughout the rainy season (October-May) and on a monthly basis in the dry season (June-September) at nine locations in southern Kaneohe Bay in support of the Coral Reef Instrumented Monitoring Platform (CRIMP) program. Another dozen or so ancillary stations were also monitored selectively. Storm events were defined as greater than 5.1 cm of rain at the Luluku rain gain in less than 24 hours. The nine southern bay stations were sampled daily for one week after or until no obvious visual evidence of the storm runoff remained.

State of Hawaii, Department of Health, Clean Water Branch Special Surveys for Bellow Beach, Oahu, Hawaii 1992-1999 (NCEI Accession 0014264)

공공데이터포털

The Monitoring Section of the State of Hawaii, Department of Health, Clean Water Branch collected water quality samples at six sites near the mouth of streams and from the surf line along Bellows Beach, Oahu, Hawaii using well-established instruments and methodologies. This dataset spans 1992-1999. This was a special project beyond the routine state-wide monitoring program.

The Monitoring Section of the State of Hawaii, Department of Health, Clean Water Branch collects water quality data at over 300 coastal locations state-wide using well-established instruments and methodologies. This dataset spans 1999-2006.

Windward Community College Heeia Stream and Kaneohe Bay Water Quality Assessment Project 2004-2005 (NODC Accession 0002449)

공공데이터포털

Measurements of water quality parameters were taken by Windward Community College faculty and students at eight sites in the Heeia Stream and adjacent Kaneohe Bay waters from May 2004 through March 2005. Parameters include Combined Nitrogen, Photo Oxidized Nitrate, Photo Oxidized Nitrite, Total Nitrogen, Total Phosphate. Data provided as MS Excel spreadsheets.

Nutrients, temperature and salinity data for Honokohau Harbor, Kealakekua Bay, and Kailua Bay, Big Island, Hawaii 2005-2007 (NCEI Accession 0059191)

공공데이터포털

This dataset was used as groundtruthing for low-altitude thermal infrared imagery of surface nearshore coastal waters of west Hawaii (the Big Island). Data are primarily temperature and salinity data taken in Honokohau Harbor and the adjacent oceanic waters from the surface to 5 m depth during August 2006. Additional Temperature and Salinity data plus nutrients (phosphates, nitrate, and silica) from fresh and brackish wells/ponds, harbors, and coastal waters were measured from August 2005 through May 2007.
