July 6, 2012 (CAPE COD) Cape Wind is set to begin a survey of the area in Nantucket Sound where they plan to build a 130-turbine wind farm. It begins today and continues through early fall. The first step involves acoustic imaging to map the seafloor. Then, sampling will be done ensure no Native American artifacts will be disturbed and to analyze the soil. That will be followed by deeper soil borings. Cape Wind hopes to begin construction next year and produce power in 2015. Critic Audra Parker of the Alliance to Protect Nantucket Sound says Cape Wind faces major obstacles before construction, including four federal lawsuits.
