Abstract— This study describes the sound produced by a
hydrokinetic turbine operating in a riverine environment near
Iguigig, AK (USA). Drifting spar buoys equipped with
hydrophones and GPS loggers were used to characterize
temporal and spatial variability in turbine sound over a range of
turbine operating conditions. Because of the...
Reference Model #1 is a tidal turbine operating in a narrow, tidal channel. The site is a generalized version of Tacoma Narrows, Puget Sound, Washington. The resource is a mixed, mainly semidiurnal tidal regime with two ebbs and floods each day of unequal strength (i.e., a diurnal inequality in which...
From April 2009 to February 2010, coupons of materials which could be used in the rotor, drive train, or foundation of tidal energy devices were deployed in-situ on the seabed at a prospective tidal energy site to screen for biofouling and corrosion. Materials include glass and carbon fiber composites, stainless...
In 2008, the US Department of Energy’s (DOE) Wind and Water Power Program issued a funding opportunity announcement to establish university-‐led National Marine Renewable Energy Centers. Oregon State University and the University of Washington combined their capabilities in wave and tidal energy to establish the Northwest National Marine Renewable Energy...
This report summarizes the outcomes of a March 22-25, 2010, workshop in Seattle, Washington, on the environmental effects of tidal energy development. The workshop focused on building capabilities to evaluate the environmental effects of tidal energy from turbines placed in the water column throughout the United States. However, it did...
