## Short summary
This dataset consists of raw data and 10-minute statistics of wind speed and wind direction measurements from a 50m offshore mast at Boockstigen, Gotland, Sweden. The period includes more than 1200 hours of offshore measurements, which starts in 1994.

## Project description
The Bockstigen off-shore wind farm consists of five 500 kW wind turbines erected three km of the SW coast of the island of Gotland on the Baltic. The project was launched in order to gain experience from bottom mounted offshore wind turbine installation. Specifcally, the method of drilling a hole for a monopile foundation, directly into the limestone rock, was in focus for the investigations.
## Measurement system
Measurements are performed in one meteorological mast, and on one instrumented turbine (no measurements in the rotating system). Data are sampled by use of several loggers (DataScan 20 Hz), and the signals are transfered through an optical fibre cable (4500 m) to an onshore cabin. Data is continiously stored on video8 tapes.
