Abstract:

Two bottom-moored Environmental Acoustic Recording System (EARS) buoys were deployed between 2017-06-08 to 2017-06-17 and recovered between 2017-10-12 to 2017-10-15. The buoys consisted of two hydrophones recording onto two paired, single-channel EARS recording systems sampling at 192 kHz each, stored in 16-bit proprietary binary format. Five buoys were recovered in October, with up to four disks each, containing raw acoustic data, but some disks were corrupted. This dataset contains an inventory of the raw acoustic files, including a complete catalog of individual files and a description of mooring location and data return. To request the raw acoustic files, please contact Dr. Natalia Sidorovskaia at nas@louisiana.edu with specific buoy/file information from the data inventory.

Purpose:

Acoustic data were collected to determine presence/absence and distribution of marine mammal species after the Deepwater Horizon oil spill, specifically sperm whales, beaked whales, and other odontocetes.

Data Parameters and Units:

Raw acoustic files are recorded in a proprietary format. After extraction of the header information and conversion to wav format, parameters include timestamp (MM/DD/YYYY HH:MM:SS), voltage (V), and sample number. Filenames contain the following information: 7dddFFFF.BBD where, 7 = year 2017 for LADC-GEMM year 3 data collection event ddd = three-digit yearday FFFF = hexadecimal index number BB = buoy number, 01 to 10 D = disk number, 0 to 3 To request raw acoustic files, please contact Dr. Natalia Sidorovskaia at nas@louisiana.edu with the exact buoy/disk/file information that corresponds to the inventory. File transfer methods will depend on the overall size of the requested data.
