Hawaiian Islands Benthic Cover with Spatial Clustering, 2005-2016

Benthic cover data from the Main Hawaiian Islands from 2005 to 2016, processed by NOAA's Pacific Islands Fisheries Science Center. The dataset results from applying a downscaling method based on contiguous clustering and mixed model analysis to National Coral Reef Monitoring Program data. It includes categories such as live hard coral cover, soft coral cover, crustose coralline algae, macroalgal and turf algae, sediment, and other.

Use Cases

• Modeling spatial ecological trends based on benthic cover categories like live hard coral and macroalgal cover.
• Assessing reef health and change over time using the 2005-2016 time series.
• Testing spatial clustering algorithms for ecological data aggregation based on the described methodology.
• Analyzing habitat composition for management zones using the derived reporting sector assignments.

Strengths

• Data spans a 12-year period from 2005 to 2016.
• Includes multiple benthic cover categories derived from four distinct survey methods.
• Methodology is documented in a peer-reviewed source (Oliver et al 2020).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may complicate direct computational analysis.
