Vogetrader Grounding Site Coral Reef Recovery Data from 2010 and 2022 in O'ahu, Hawaii

Six datasets document benthic coral data and imagery collected to evaluate reef recovery and restoration efficacy at the M/V Vogetrader grounding site in O'ahu, Hawaii. NOAA's PIFSC Ecosystems Science Division collected data in 2010 and 2022, covering coral size, abundance, outplant assessment, juvenile density, and photoquadrat imagery. The data supports a 2024 publication analyzing long-term outcomes of passive and active restoration techniques.

Use Cases

• Assessing coral recovery trajectories based on before-after (2010 vs. 2022) coral size and abundance data.
• Comparing the efficacy of restoration techniques (outplanting, rubble removal, passive) using data from three injury zones and reference sites.
• Analyzing benthic and rubble cover from annotated photoquadrat imagery collected along transect lines.
• Evaluating coral outplant survival and health based on recorded species, size, and partial mortality extent.

Strengths

• Includes a 12-year time series with 'before' (2010) and 'after' (2022) data for a Before-After Control-Impact (BACI) design.
• Data collection followed established protocols, including the National Coral Reef Monitoring Program (NCRMP) method for benthic cover.
• Surveys included 10 quadrat replicates per habitat type across impact and reference sites for statistical robustness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data is provided in PDF format, which may require extraction and conversion for computational analysis.
