Description
| 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. |

Notes
| In situ observations of hydrography, currents, and winds during four separate study periods, were obtained, each with its own final data file and archive. For each a pair of one surface mooring and one subsurface mooring were deployed in the center of a long-term HFR coverage area and within the Vineyard Wind 1 lease area. The central surface mooring, stationed along the 40-m isobath, hosted a Vaisala WXT520 weather station and water column hydrography using 7 or 8 temperature-conductivity (CT) sensors (SBE37 Microcats). A nearby subsurface mooring supported an upward-looking ADCP to collect high resolution velocity profiles of the top 8 m of the water column. While all mooring data was returned during all periods, ADCP observations during WTRIM 2 were limited to the first 2 weeks of the deployment. |

| The detailed deployment information for each deployment is given separately. In all, the surface mooring was deployed at 41.0669 degN 70.4828 degW in 40 m of water and sampled surface vector winds, air temperature, air pressure, and relative humidity using a Vaisala WXT520 located at 2 m above mean sea level at 10 min ensemble averages, of 1 Hz data. The Center surface mooring also had 8 temperature-conductivity sensors (SBE37s) that sampled the oceanic water column at fixed depths below the surface of 0.6,4,6.5,10,15,20, and 30 m at 2-min increments. The subsurface mooring was deployed less than 50 m away from the surface mooring at 41.0669 degN 70.4828 degW and contained a sub-surface float at 8-m below sea level in 40 m of water. The float held an upward looking Nortek Signature 1000 AD2CP that collected 2048 pings @4Hz every 20 min at 0.25 m bin depths. The actual depth of the subsurface float varied from deployment to deployment, depending on the length of the mooring, ranging from 10 m to 8 m below the surface. The CT observations were processed to remove both temperature and conductivity spikes as well as biases due to conductivity drift before being used to estimate salinity and density. ADCP along-beam velocities were processed following Kirincich (2009, JPO) to give time series of quality controlled, surface-referenced, horizontal velocities from ~1 m below the surface to 2-4 m above the mean instrument position due to tidal height variability. Acoustic side lobe interference (Gordon, 1996) was carefully estimated, and the exact bin of the side-lobe masking was determined using a precise, signal intensity-based, estimate of the sea surface height that accounted for tidal variability of the water column. All moored timeseries were averaged over independent 1/2 hour time intervals, centered on the hour. |
