Kaneohe Bay Water Quality and Storm Response Data

Water column profiles and surface water samples were collected to monitor the impact of storm runoff on coral reefs in southern Kaneohe Bay, Hawaii. Sampling occurred at nine primary stations on a bi-monthly basis during the rainy season and monthly during the dry season from 2005 to 2007, with intensified daily sampling following storm events. The dataset was generated by NOAA's National Centers for Environmental Information in support of the Coral Reef Instrumented Monitoring Platform (CRIMP) program.

Use Cases

• Analyzing relationships between storm events (defined as >5.1 cm rain/24h) and changes in nutrient concentrations like ammonium (nh4+), nitrate (no3-), and phosphate (po43-).
• Modeling temporal and spatial variability of water quality parameters such as salinity, dissolved oxygen, chlorophyll-a, and pH across nine monitoring stations.
• Investigating the duration and dissipation of storm runoff plumes by tracking parameters like specific conductivity (spcond), fluorescence, and dissolved silica (sio2) over daily post-storm sampling periods.

Strengths

• Includes high-frequency daily sampling for one week following storm events, capturing short-term dynamics.
• Covers a multi-year period (2005-2007) with consistent seasonal sampling protocols (bi-monthly rainy season, monthly dry season).
• Monitors a wide range of physical and chemical water quality parameters, including nutrients, salinity, and dissolved oxygen.

Limitations

• Exact row count, dataset size, and complete column list are not provided by any source platform.
• Conflicting last updated dates exist between sources (2007-10-25 vs. 2026-03-05), creating uncertainty about data currency.
