National Coral Reef Monitoring Program: Assessing and Monitoring Cryptic Reef Diversity of Colonizing Marine Invertebrates using Autonomous Reef Monitoring Structures (ARMS) Deployed at Coral Reef Sites across the Pacific Remote Island Areas from 2015-04-08 to 2018-08-05 (NCEI Accession 0226243)
This dataset includes species identification data gathered from Autonomous Reef Monitoring Structures (ARMS). The 2-mm fraction morphospecies data provided in this dataset are from ARMS deployed in 2015 and recovered in 2018 at permanent reef sites around Pacific Remote Island Areas during NCRMP missions. These ARMS are used by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) to assess and monitor cryptic reef diversity in Pacific Remote Island Areas as part of the ongoing National Coral Reef Monitoring Program (NCRMP). Developed in collaboration with the Census of Marine Life (CoML) Census of Coral Reef Ecosystems (CReefs), ARMS are 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.
This data was gathered at specific reef sites across Pacific Remote Island Areas. At these sites, divers entered the water and deployed and/or recovered the ARMS unit. Each unit used to gather this data consists of 23 cm x 23 cm gray, PVC plates stacked in alternating series of 4 open and 4 obstructed layers and attached to a base plate of 35 cm x 45 cm that is affixed to the reef. They are designed to mimic the structural complexity of a reef and attract colonizing invertebrates. Soak times are approximately 3 years. Refer to the data to determine how long a particular unit was underwater as soak times can vary by location.
Upon recovery, each ARMS unit was encapsulated, brought to the surface, disassembled and processed on-board the research ship. Disassembled plates were photographed to document recruited sessile organisms, scraped clean, and preserved in 95% ethanol for future DNA processing. Recruited motile organisms were then sieved into 3 size fractions: 2 mm, 500 um, and 100 um. The 500-um and 100-um fractions were bulked and preserved in 95% ethanol for future DNA processing. The 2-mm fraction was sorted into morphospecies. The DNA sequencing data are not included in this dataset.

Purpose | The use of ARMS is a systematic, consistent, and comparable method for monitoring the marine cryptobiota community in coral reef ecosystems over time. The NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP coordinates various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. NCRMP is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the CRCP and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), and many other partners. The Ecosystem Sciences Division at NOAA Fisheries is leading climate monitoring in the U.S. Pacific Islands Region. The climate component of NCRMP in the Pacific provides a comprehensive view of climate change impacts on coral reef ecosystems and helps identify areas of resilience and vulnerability. The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) ecological impacts by collecting data on coral growth rates, erosion, and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem. Each year, ESD scientists work closely with CRCP and partners during Pacific RAMP missions to collect data using moored oceanographic (subsurface temperature recorders) and ecological (calcification accretion units [CAUs] and autonomous reef monitoring structures [ARMS]) instruments stationed at fixed sites in the Pacific Ocean, and water samples collected by divers. The in-situ data (along with satellite-based observations) are also used in modeling efforts. Innovative analysis techniques are used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time. |
