Cryptobiota metabarcoding using Autonomous Reef Monitoring Structure (ARMS) Deployed at Coral Reef Sites across Timor Leste from 2012 to 2014

Published by Pacific Islands Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 10, 2026 at 06:01 AM | Dataset Last Updated: May 05, 2021 at 12:00 AM
The data described here includes cytochrome oxidase I (COI) DNA metabarcoding data collected from Autonomous Reef Monitoring Structures (ARMS). ARMS were deployed by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) in Timor Leste under USAID Timor Leste. Developed in collaboration with the Census of Marine Life (CoML) Census of Coral Reef Ecosystems (CReefs), ARMS were designed to mimic the structural complexity of a reef and attract/collect colonizing marine invertebrates. The key innovation of the ARMS method is that biodiversity is sampled over precisely the same surface area in the exact same manner. These data were gathered at specific reef sites across Timor-Leste. ARMS units were set-up, deployed and recovered as described in the ARMS record in the related items section below. After ARMS were disassembled, different size fractions of samples and plate scrapings were preserved in ethanol for metabarcoding.
