One of the main criteria for evaluation of potential tidal energy sites is the current speed. ASL has been involved in several site evaluation projects such as Race Rocks, Victoria, and others near Campbell River. Flow measurements are often augmented by numerical modelling.

In order to design the bases for offshore wind turbines the engineers need to know the waveregime. ASL conducted a winter long study of wave and current measurement at a proposed wind farm site in Hecate Strait using a bottom-mounted TRDI ADCP wave gauge. Storms occurred every few days with significant wave heights (Hs) reaching 6 m and generating current surges of 5m/second.
The fact that ocean waves have enough energy to require marine engineers to factor them into their designs also makes them a promising renewable resource. Potential wave energy sites along the BC coast and worldwide are being evaluated and measurements being made to access the long term wave climates.
