Technology Related Environmental Impacts: As the marine renewable energy developers move into permitting
and implementation, need assessment of potential environmental effects.
Scouring Studiespresently underway
in Muskeget Channelto understand effectson sediment transport
Bio-fouling Effects fromTechnology Deployment in
Muskeget Channel
Environmental Evaluations – Muskeget ChannelMooring Structures
Test Mooring Structure to evaluate sediment movement in high velocity zone. Instrumented with velocity sensors and tilt gauges.
