Pore Water Geochemistry of Hawaiian Reef Sediments from 1996-1997

NOAA_NCEI provides a dataset examining the geochemical behavior of permeable reef flat sediments on Checker Reef, Oahu, Hawaii. It captures spatial and temporal changes in pore water dissolved oxygen, nitrate, nitrite, ammonium, and nitrous oxide. The data was collected between October 1996 and July 1997 to study hydraulic control of geochemistry following significant wave events.

Use Cases

• Analyzing temporal changes in dissolved oxygen to study oxic-suboxic zone dynamics.
• Correlating nitrate and nitrite concentrations with wave events to understand hydraulic control.
• Mapping spatial distributions of ammonium and nitrous oxide across the reef flat.
• Studying post-disturbance recovery of pore water geochemistry in a permeable sediment system.

Strengths

• Data collection targeted a specific hydraulic control process following significant wave events.
• Monitored multiple key geochemical species (O2, NO3-, NO2-, NH4+, N2O) relevant to nitrogen cycling.
• Temporal coverage spans a 9-month period from October 1996 to July 1997.
• Cross-platform presence on NASA EarthData and Data.gov indicates recognized importance.

Limitations

• Exact row count, file size, and complete column names are not provided by any source.
• Sources conflict on the last updated date (1997-07-03 vs 2026-03-05), creating ambiguity about metadata maintenance.
• License information is not specified for any platform.
