Abstract:

This dataset includes an inventory of detected fish-produced sounds recorded in the Main Pass site (29° 15.3’ N and 88° 17.8’ W) in the Gulf of Mexico from 2010-07-07 to 2012-09-29. Recordings were made by High-Frequency Acoustic Recording Packages (HARPs) a few months to two years after the Deepwater Horizon Oil Spill. The HARPS were bottom-moored in 93m of water. The data were scanned by a combination of manual analysis and computer algorithms to identify fish sounds. The sounds are classified as one of seven (“croack”, “jet-ski”, “downsweep”, “pulse train”, “beats”, “buzz”, and “other”) but cannot be attributed to an exact fish species. Each identified instance of fish-produced sound is logged by type, with the date and time/sixty-minute bin within which it occurred.

Purpose:

Dataset was developed to assess the population of sound producing fish in the Gulf of Mexico at the time and following the Deepwater Horizon oil spill.

Data Parameters and Units:

Detections: Species Code [all UF, Unidentified Fish], type of call, start time of call [GMT].

Methods:

Passive acoustic monitoring was conducted with High-frequency Acoustic Recording Packages. These data were scanned for sound producing fish using a combination of computer algorithms and manual (analyst) scanning of the waveform and spectral data.

Instruments:

High-Frequency Acoustic Recording Package (HARP).

Error Analysis:

False detection rate of less than 10%.
