Maryland BOEM M14AC00018 Raw Audio Data
The project collected three years of baseline data 12 - 60 km offshore of Maryland prior to construction and operation of an offshore wind energy facility. Two main types of sound recording devices that encompassed a range of frequencies were used to detect vocalizations from baleen whales (low frequencies) and toothed whales (high frequencies): the Marine Autonomous Recording Unit (MARU, or pop-up) sampling at 2 kHz and the C-POD (cetacean click detector), which monitors the 20 - 160 kHz frequency range. These were supplemented by additional acoustic recorders during select periods of the study at five sites to provide further information on mid-frequency sounds, such as dolphin whistling behavior. The use of a grid array design for the acoustic detection devices within the Maryland WEA facilitated localization of vocalizing whales to further understand spatial patterns of habitat usage. RESULTS: There is substantial overlap between marine mammals and the Maryland WEA, but this varies seasonally. While the risk to endangered whales is lowest during the summer, the risk to bottlenose dolphins may be highest at this time, as they are most abundant in the summer time. The year-round occurrence of marine mammals offshore of Maryland will require decision-makers to consider the trade-off of the potential impacts
