Wind Turbine Radar Interference Mitigation (WTRIM) in Situ Validation and Verification Data Collection

This data was collected by the Woods Hole Oceanographic Institution, PI Kirincich, as part of a series of experiments focus on understanding and mitigating the potential impacts of offshore wind turbines on the data collected by land-based HF radar (HFR) systems. The deployments made detailed observations of atmospheric and oceanic properties in areas where wind turbines were being built, operating in small numbers, and operating in larger numbers in the presence of HFR systems measuring surface currents. In situ parameters to be measured included surface atmospheric winds, meteorological properties, near surface ocean currents, hydrographic properties of the ocean such as temperature and salinity at multiple depths. These properties were measured from a pair of moored buoys deployed in the Vineyard Wind I lease area south of Martha's Vineyard Massachusetts. The project also sought to obtain in situ video of the spinning blades of the turbines proximate to the mooring that could be used to provide estimates of the blade rotation rates, visibility assessments of the turbines over time, and potential flicker or visual issues related to the blades that might be of interest to Coast Guard and other first responders. These data are provided separately and not included here. Data were collected within four separate measurement periods: August to October 2023, February to April 2024, April to September 2024, and March to July 2025.
