Benthic percent cover derived from analysis of benthic images collected at coral reef sites in Timor-Leste in 2013 and 2014 (NCEI Accession 0168620)
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.

Supplemental Information | Submission Package ID: X1150E The images used in this analysis were archived separately and can be found in this archive package: Benthic images collected at coral reef sites in Timor-Leste from 2012-10-15 to 2014-10-09 (NCEI Accession 0166378) |
Purpose | 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). |
