NTR: autonomous reef monitoring structures (arms)

[cpavloud]

Autonomous Reef Monitoring Structures (ARMS) are standardized 3D collectors of marine life that mimic the complex structure of the sea bottom that is hard to sample without destroying natural habitat. ARMS units are passive monitoring systems originally developed during the Census of Marine Life project for the collection of marine fauna on and near the sea floor. They are stacks of PVC settlement plates that are fixed to each other and to a stable base. They are deployed on marine substrates and colonised by marine species. After a period of time they are recovered and taken apart to see which species colonised them.
