‘Ike Wai:

In 2016, University of Hawai‘i launched the Hawai‘i EPSCoR ‘Ike Wai project supported by the National Science Foundation (Award # OIA-1557349) The five-year project uses integrated research, education, and community engagement efforts aimed to ensure Hawai‘i’s future water security and promote resource management within the state that is sustainable, responsible, and data-driven.

To save space on Hydroshare, all ‘Ike Wai project files are stored at the University of Hawai‘i and linked here. Please use the following link(s) to see the files for this resource.

Variables

  • Phosphorus, total dissolved

    id: TDP_uM

    unit: micromoles per liter(umol/L)

    description: Total dissolved phosphorus concentrations (μM) in discrete water samples. Samples were filtered onsite through a 0.45 μM filter and collected into acid-cleaned HDPE bottles and kept at 4 °C until analysis. TDP samples were analyzed in the lab with a SEAL AutoAnalyzer 3 HR in the S-Lab at the University of Hawaiʻi at Mānoa.

  • Nitrogen, total dissolved

    description: Total dissolved nitrogen concentrations (μM) in discrete water samples. Samples were filtered onsite through a 0.45 μM filter and collected into acid-cleaned HDPE bottles and kept at 4 °C until analysis. TDN samples were analyzed in the lab with a SEAL AutoAnalyzer 3 HR in the S-Lab at the University of Hawaiʻi at Mānoa.

    id: TDN_uM

    unit: micromoles per liter(umol/L)

  • Nitrogen, dissolved (free+ionized) Ammonia (NH3) + (NH4)

    description: dissolved ammonium concentrations (μM) in discrete water samples. Samples were filtered onsite through a 0.45 μM filter and collected into acid-cleaned HDPE bottles and kept at 4 °C until analysis. Ammonium samples were analyzed in the lab with a SEAL AutoAnalyzer 3 HR in the S-Lab at the University of Hawaiʻi at Mānoa.

    id: NH4_uM

    unit: micromoles per liter(umol/L)

  • Nitrogen, dissolved nitrite (NO2) + nitrate (NO3)

    description: dissolved nitrate and nitrite concentrations (μM) in discrete water samples. Samples were filtered onsite through a 0.45 μM filter and collected into acid-cleaned HDPE bottles and kept at 4 C until analysis. Nitrate and nitrite samples were analyzed in the lab with a SEAL AutoAnalyzer 3 HR in the S-Lab at the University of Hawaiʻi at Mānoa.

    id: NO3_NO2_uM

    unit: micromoles per liter(umol/L)

  • Phosphorus, phosphate (PO4)

    description: dissolved phosphate concentrations (μM) in discrete water samples. Samples were filtered onsite through a 0.45 μM filter and collected into acid-cleaned HDPE bottles and kept at 4 °C until analysis. Phosphate samples were analyzed in the lab with a SEAL AutoAnalyzer 3 HR in the S-Lab at the University of Hawaiʻi at Mānoa.

    unit: micromoles per liter(umol/L)

    id: PO43_uM

  • Water depth

    id: CTD_depth_m

    unit: meter(m)

    description: water depth (m) measured with a CTD Diver (Schlumberger Inc.) at the time of sampling (for both discrete and time series measurements)

  • Longitude

    id: Long

    description: Sampling site longitude measured with a Garmin GPSMAP 64 Handheld GPS in decimal degrees

  • Latitude

    id: Lat

    description: Sampling site latitude measured with a Garmin GPSMAP 64 Handheld GPS in decimal degrees

  • undefined

    id: Date

    value type: Field Observation

    description: sampling date, in Hawaii Standard Time (HST), date format is: MM/DD/YY

  • undefined

    id: Site

    description: CA# refers to canal sampling sites, CO# refers to coastal sampling sites and SD# refers to storm drain sampling sites. For canal/ coastal sites: CA/CO# (CA/CO indicates canal/coastal and the # indicates the specific coastal site) K = King tide S = Spring tide L = low tide M = mid tide H = high tide Surf = surface water sample Gw = groundwater sample For storm drain sites: SD# (SD indicates storm drain and the # indicates the specific storm drain site) LT = low tide MT = mid tide HT = high tide

    value type: Field Observation

  • Salinity

    id: Salinity

    description: measured in the field during discrete sample collection using a YSI multiparameter sonde

  • Radon-222

    id: Rn_Bqm3

    unit: becquerels per cubic meter(Bq/m3)

    value type: Laboratory Observation

    description: Radon concentrations (Bq/m3) measured using a Durridge RAD7 radon-in-air detector with water analysis accessory. Samples were collected in the field into 250 mL glass borosilicate bottles without headspace and analyzed the same day upon returning from the field. All discrete samples were decay corrected to the time of sample collection.

  • Fluoroquinolones

    id: FQL_ngL

    unit: nanograms per liter(ng/L)

    description: concentration of fluoroquinolones in the discrete sample in ng/L. Discrete samples were filtered onsite through a 0.45 μM filter and collected into pre-combusted amber glass bottles with Teflon lids and kept at 4 °C until analysis. Fluoroquinolones samples were analyzed in the lab using Enzyme Linked ImmunoSorbent Assay (ELISA) compound-specific kits (Abraxis LLC). Following compound-specific instructions provided with each kit for sample preparation, fluoroquinolones was analyzed against known standards at a 450 nm wavelength on a spectrophotometric microplate reader (Abraxis ON 475010, microplate format, 96 well, Model 4303).

  • Caffeine

    id: CFN_ngL

    unit: nanograms per liter(ng/L)

    value type: Laboratory Observation

    description: concentration of caffeine in the discrete sample in ng/L. Discrete samples were filtered onsite through a 0.45 μM filter and collected into pre-combusted amber glass bottles with Teflon lids and kept at 4 °C until analysis. Caffeine samples were analyzed in the lab using Enzyme Linked ImmunoSorbent Assay (ELISA) compound-specific kits (Abraxis LLC). Following compound-specific instructions provided with each kit for sample preparation, caffeine was analyzed against known standards at a 450 nm wavelength on a spectrophotometric microplate reader (Abraxis ON 475010, microplate format, 96 well, Model 4303).

  • Carbamazepine

    id: CBZ_ngL

    unit: nanograms per liter(ng/L)

    description: concentration of carbamazepine in the discrete sample in ng/L.
