Abstract
The Hudson South 2 E05 (HS2 E05) NYSERDA buoy was installed in late Jan 2022. The bat and bird acoustic detectors were operational after the first service trip in Jun 2022. This report summarizes bat and bird acoustic data associated with the HS2 E05 buoy collected from Jun 2022 through Oct 2022. The SM4BAT and SM4 bird-acoustic detectors were retrieved in Feb 2023; however, a fatal clock error and power fluctuations caused SM4BAT detectors to fail early and stop recording on 03 Oct 2022. The SM4 bird-acoustic detectors also experienced these issues but storage cards reached capacity on 04 Oct 2022 before any data were affected. Analyses and results thus show all identified species recorded during this operational period (Table 1).
The bat and bird acoustic sensors at HS2 E05 have recorded 13 bat and 5 bird vocalizations representing two bat species (silver-haired bat and Eastern red bat) and one bird species (herring gull) (Table 1).
We matched bird observation times to LiDAR-derived wind speed at 98 m, which was collected simultaneously from the buoy. Meteo wind data substituted any periods when LiDAR was nonoperational. We summarized wind speed to the nearest whole value and generated a distribution to determine the proportion of observations at the recorded wind speed values.
