Vogetrader Long-Term Monitoring 12 years After Impact: a collection of benthic data and imagery collected to evaluate reef recovery and the efficacy of restoration efforts at th...

On February 5, 2010, the cargo vessel M/V Vogetrader ran aground a shallow forereef in Oahu, Hawaii. In response to the loss of natural resources, three restoration techniques were implemented in 2013: coral outplanting, rubble removal, and passive restoration. In November 2022, monitoring surveys were conducted across three injury zones and nearby reference sites to assess recovery trajectories and compare the efficacy of the restoration efforts. Data collected before restoration during the initial damage assessment in 2010 is also included in the datasets described in this metadata record to improve usability and access for future datasets.

There are 6 datasets described in this metadata record:

Two datasets including 2010 and 2022 data for (1) coral size for identified taxa at the Vogetrader impact and reference sites across zone, habitat type, and quadrat replicate; and (2) coral abundance for identified taxa at the Vogetrader impact and reference sites across zone, habitat type, and quadrat replicate.

Four datasets of only 2022 data:(1) coral outplant assessment of species, size, and extent of partial mortality ; (2) juvenile coral density and settlement on rubble across varying sites of impact; (3) raw annotations of photoquadrat imagery for analysis of benthic/rubble cover across varying sites of impact; (4) photoquadrat imagery across varying sites of impact

Data was collected by NOAA's PIFSC Ecosystems Science Division. Funding was provided by PIRO and Hawaii's Division of Aquatic Resources. These data were gathered at the vessel grounding site located on the southern channel entrance to Barbers Point Harbor at a depth of 10 to 14m.

Before-After Control-Impact (BACI) and control-impact survey designs included 10 quadrat replicates for all habitat types of the impact and reference sites. 'Before' refers to 2010, and 'After' refers to 2022. Within each quadrat, divers recorded coral species, maximum diameter, juvenile coral density, and the number of juvenile corals attached to unconsolidated reef framework. To evaluate benthic cover, a traditional National Coral Reef Monitoring Program (NCRMP) protocol was followed; digital photoquadrat images were taken along transect lines at each site. These images were annotated with the web tool CoralNet; ten images were randomly selected per site, overlaid with ten random points, and annotated as either rubble or non-rubble substrate. The assessment of coral outplants included recording species, maximum diameter, and the extent of partial mortality for all outplants relocated in the field.

These data are one of the results of the preferred primary restoration alternative of monitoring the natural recovery of the grounding site as outlined in the FINAL DAMAGE ASSESSMENT AND RESTORATION PLAN and NEPA EVALUATION for the FEBRUARY 5, 2010, M/V VOGETRADER GROUNDING at KALAEOLOA, BARBERS POINT, OAHU.

These monitoring surveys were conducted across three injury zones and nearby reference sites to assess recovery trajectories and compare the efficacy of the restoration efforts.

This record will be updated with a link to relevant publications once manuscript has been published.

This child item is one data dictionary for multiple datasets, as there are mostly shared columns. Data was collected on coral density, size, and community composition at the VogeTrader impact and reference sites in 2010 and 2022. Rubble cover, juvenile coral density, and proportion of juvenile corals settled on unconsolidated rubble at the VogeTrader impact and reference sites in 2022, as well as size and extent of partial mortality of coral outplants in 2022.

While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

NOAA Ecosystem Science Division (ESD) Data Sharing Recommendations, version 9.0 updated August 12, 2015:

ESD welcomes the opportunity to collaborate on research issues contributing to the scientific basis for better management of marine ecosystems. ESD has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols.

The following recommendations are for your consideration as you use this data:

1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with ESD principal investigators.

2) In all presentations, product releases, or publications using data generated by ESD, proper acknowledgement of both ESD and the individuals responsible for data collection is expected. Citing the DOI (if available) is preferred, a non-DOI example is listed below.

3) If you collect or generate data for the same study areas, ESD requests that you share relevant information on complimentary data collections.

4) Those receiving data are strongly urged to inform the ESD Data Management Team of any errors and discrepancies that are discovered during the course of using these data. They are further urged to bring to the attention of the Team all problems and difficulties encountered in using these data. This information is necessary in order to improve the collections and to facilitate more efficient and economical data processing and retrieval. The users are asked to supply copies of any missing data that may be located, and to provide information as to significant subsets and special aggregations of data that are developed in using the material provided.

The data was managed with Microsoft Excel and QC'd and analyzed with R.

Ten replicate plots were used within each zone/habitat type to reduce bias related to spatial sampling of coral communities.

The survey design and selection criteria used for collection of the 2022 dataset were consistent to that of the initial 2010 impact assessment to allow for direct comparisons across years.

The data set adheres to the sampling techniques used in the initial 2010 impact assessment.

These data underwent quality control procedures by the PI of the project during the translation from field-sheets. No omission of data from the field-surveys was needed.
