Pacific Islands Fisheries Science Center, PIFSC Special Publication, SP-17-002, 234 p. https://doi.org/10.7289/V5/SP-PIFSC-17-002. The benthic cover data described here result from benthic photo-quadrat surveys conducted by the NOAA Coral Reef Ecosystem Program (CREP) in hard bottom shallow water (< 15 m) habitats in Timor-Leste during reef fish surveys surveys at 150 sites that were selected using a stratified random sampling design in June 2013, and along transects at fixed climate survey sites in September-October 2014 (10 sites and 8 sites, respectively). Climate sites were established by CREP to establish ecological baselines for climate change by measuring multiple features of the coral reef environment (in addition to the data described herein) over time. The reef fish surveys were conducted to generate baseline data on the nearshore coral reef fish assemblages and associated benthic communities around Timor-Leste's north coast and Atauro Island. Percent benthic cover for each site is estimated from a photo-transect (30 photographs, taken at 1-m intervals, 10+ points analyzed per photograph using Coral Point Count with Extensions). NA values represent situations where images were either not gathered or not analyzed. These benthic cover data for Timor-Leste provide an estimate of the benthic community composition at each survey site, and give context to the results from the other survey components. The benthic images, and the associated reef fish survey data and parameters measured to establish ecological baselines for climate change are documented separately. The data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive. In 2011, NOAA and the United States Agency for International Development (USAID) Timor-Leste Mission formed a 5-year bi-lateral partnership agreement from 2012 to 2016, in support of the Government of Timor-Leste—particularly the Ministry of Agriculture and Fisheries (MAF)—by addressing significant information gaps in their nearshore marine ecosystems. Specifically, MAF asked NOAA to address the following questions: 1. Where are the nearshore marine resources? 2. What are the nearshore marine resources? 3. How are they changing over time and what threats are potentially causing these changes? 4. What approaches are needed to manage and conserve the nearshore marine resources? With financial support from USAID and in-kind support from the NOAA Coral Reef Conservation Program (CRCP), the NOAA Coral Reef Ecosystem Program (NOAA-CREP) conducted baseline ecosystem assessment surveys to inform ecosystem-based management planning in Timor-Leste. The primary activities conducted by NOAA to answer these questions included: 1. satellite mapping of nearshore habitats, 2. conducting coral reef ecosystem assessments, 3. establishing ecological baselines for climate change, and 4. building management capacity by developing a spatial data framework The benthic cover data described herein resulted from the second and third activities to conduct coral reef ecosystem assessments (2013) and establish ecological baselines for climate change (2014).

Each time a production run is performed for a region, a calibration exercise is conducted by all staff that will participate in that round of image analysis classification. Usually 100-150 photos are selected from the photos being processed as part of the production run series, or other region-relevant photo streams. Then, CPCe assigns 10 random points per photo. Each photo analyst is asked to classify the same set of points in each of the photos used as part of the calibration exercise. The goal of the calibration exercise is to assess inter-observer variability. Inter-observer variability rates are available upon request for each production run. Handheld GPS units were used to locate and mark site locations. Analytical Accuracy Data sets derived from image analysis include 30 benthic photographs per survey site. Photoquadrat surveys are along one 30 m transect for reef fish surveys. The climate team conducts the surveys along 2 independent transects. Appropriate site level benthic cover estimates are generated from all 30 images. Completeness Measure Photoquads were taken at all climate sites surveyed, and at 139 of the 150 fish sites surveyed. Completeness Report The data set derived from the image analysis is as good as the images themselves; poor images with low contrast, inappropriate white balance, or out of focus may have to be discarded. Therefore, percent cover estimates for some sites may derive from differing number of points between sites. Although the analysis process is statistically robust to allow for differing n (points) between sites, users should be aware of this limitation. Only shallow water (0 to 30 meter depth range) hard-bottom habitats are surveyed. HABITAT_CODE was not recorded at climate sites. Conceptual Consistency The same method of image analysis was used at each surveyed site. The benthic photoquadrat survey methodology, employed by the NOAA Coral Reef Ecosystem Program (CREP) since 2013. Benthic imagery is collected at survey sites and is analyzed using Coral Point Count with Excel Extentions (CPCe) to derive benthic cover values. The benthic photoquadrat imagery were analyzed using Coral Point Count with Excel extensions (CPCe; Kohler and Gill 2006) software. CPCe assigns 10 random points per photo and the benthic elements falling directly underneath each point is identified to two functional group levels: Tier 1 (e.g. hard coral, soft coral, macroalgae, turf algae, etc.) and Tier 2 (e.g. Hard coral by morphology = massive, branching, foliose, encrusting, etc.; Macroalgae = upright macroalgae, encrusting macroalgae, bluegreen macroalgae, and Halimeda, etc.). The detailed list of each functional group level or tier is included in the benthic image analysis classification scheme. Raw survey data includes unique image name and individual point observations identified at two functional group levels of benthic cover with the corresponding physical data which reflect the description of the site. The physical data for all records includes the following: region, island, site, date (day, month, year), latitude (dd), longitude (dd), reef zone, habitat type, depth category, minimum depth and maximum depth.
