![]() Power is produced by the motion of the wave, which causes the ambient pressure in the air chamber to vary thereby forcing air to flow through the Wells turbine. This L- shaped device opens to the ocean downstream from the wave propagation direction. The water column is a concept used in oceanography to describe the physical (temperature, salinity, light penetration) and chemical (pH, dissolved oxygen, nutrient salts) characteristics of seawater at different depths for a defined geographical point. First proposed by Masuda, the BBDB design is a floating Oscillating Water Column (OWC) device that consists of an air chamber, an L-shaped duct, bow and stern buoyancy modules, and a power take-off (PTO) composed of a Wells air turbine and a generator. Reference Model 6 (RM6) is a Backward Bent Duct Buoy (BBDB), which is a type of oscillating water column wave energy converter. The RMP project team, led by Sandia National Laboratories (SNL), included a partnership between DOE, three national laboratories, including the National Renewable Energy Laboratory (NREL), Pacific Northwest National Laboratory (PNNL), and Oak Ridge National Laboratory (ORNL), the Applied Research Laboratory of Penn State University, and Re Vision Consulting. The point designs also served as open-source test articles for university researchers and commercial technology developers. Most plants can take in nutrients through both routes, and there are advantages to having nutrients in both locations. Department of Energy (DOE), was a partnered effort to develop open-source MHK point designs as reference models (RMs) to benchmark MHK technology performance and costs, and an open-source methodology for design and analysis of MHK technologies, including models for estimating their capital costs, operational costs, and levelized costs of energy. There are two approaches to fertilization: dosing directly into the tank with liquid fertilizers (water column dosing approach) and using substrate based fertilizers (rootzone fertilization). The Reference Model Project (RMP), sponsored by the U.S. In a water column sweep, a modified dip net (where the net is angled 90 degrees from the handle) is plunged vertically to the benthos, minus the distance of the net height, and slowly towed vertically to the surface to capture free-floating macroinvertebrates within the water column. This data was generated upon completion of the project on September 30, 2014. These full scale geometry files are saved as SolidWorks assembly, IGS, and STEP files, and require a CAD program to view. Contains the Reference Model 6 (RM6) full scale geometry files of the Oscillating Water Column, developed by the Reference Model Project (RMP).
