NOAA_NCEI provides a nine-year annual quantitative monitoring dataset of shallow marine communities inshore of the Sand Island Ocean Outfall, Oahu, Hawaii. The report focuses on benthic and fish community structure to detect changes, covering the period from 1990 to 1998. Analysis showed no statistically significant change in most biological parameters measured, except for invertebrate species and individual counts.
Use Cases
- Analyze trends in percent coral cover and number of coral species over nine years to assess reef health.
- Model relationships between invertebrate species counts, such as Spirobranchus giganteus corniculatus, and environmental disturbances.
- Compare fish species richness and total fish biomass across stations to evaluate gradients in community development.
- Assess recovery of coral communities by examining data from before and after Hurricane Iniki in 1992.
- Detect changes in mean number of invertebrate species and individuals per transect across the monitoring period.
Strengths
- Nine consecutive years of annual monitoring data
- Analysis includes multiple biological parameters: coral cover, species counts, and fish biomass
- Data collection designed to capture gradients in community development across stations
Limitations
- Specific row count, column names, and sample size are not provided
- Data is over 25 years old, limiting analysis of current conditions
- Geographic scope is limited to selected sites fronting Sand Island, Oahu
