Abstract
Twin acoustic surveys were designed to simultaneously monitor bat activity on two of the large barges used for the construction of Block Island’s offshore wind turbines. Bat activity was monitored on the two vessels as they traveled between the Block Island Wind Farm and the Port of Providence. Two ultrasonic acoustic detectors were deployed on each vessel and operated for approximately two weeks in August 2016 during construction. Substantial variability in bat pass rates was observed, and those bats that could be identified were discovered to be migratory tree-roosting bats.
