Pacific Remote Island Coral Reef Benthic Images Since 2014

National Oceanic and Atmospheric Administration benthic habitat imagery from stratified random surveys across the Pacific Remote Island Areas since 2014. The data result from photo-quadrat surveys along transects conducted as part of Rapid Ecological Assessment surveys for corals and fish. A stratified random sampling design was employed, encompassing reef and hard bottom habitats in the 0-30 meter depth range.

Use Cases

• Estimating benthic cover based on photo-quadrat imagery
• Analyzing benthic community taxonomic composition from habitat imagery
• Comparing coral reef health across strata based on island, reef zone, and depth
• Monitoring long-term ecological changes in Pacific Remote Island Areas since 2014

Strengths

• Data collection employs a stratified random sampling design to reduce estimate variance
• Survey domain encompasses reef and hard bottom habitats in the 0-30 meter depth range
• Sampling effort was allocated based on strata area including island, reef zone, and depth

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Site-level estimates and site to site comparisons should be used with caution as noted in the description
