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 Mariana Archipelago from 2011 to 2017

Metadata Updated: February 27, 2019

Autonomous Reef Monitoring Structures (ARMS) are used by the Ecosystem Sciences (ESD) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) to assess and monitor cryptic reef diversity of colonizing marine invertebrates. The 2-mm fraction morphospecies data provided in this dataset are from ARMS recovered since 2014 from permanent reef sites across the Mariana Archipelago during NCRMP missions.

Each ARMS unit, designed to mimic the structural complexity of a reef and attract colonizing invertebrates, consisted of 23 cm x 23 cm gray, type 1 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, which was affixed to the reef by divers and recovered ~3 years later. Developed in collaboration with the Census of Marine Life (CoML) Census of Coral Reef Ecosystems (CReefs), ARMS sample biodiversity over precisely the same surface area in the exact same manner. Thus, the use of ARMS is a systematic, consistent, and comparable method for monitoring the cryptobiota community over time.

Upon recovery, the ARMS unit was encapsulated, brought to the surface, and disassembled and processed on-board the NOAA 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 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.
