We have submitted our raw acoustic data (BowdoinCalFr_6229.zip), collected in Inglefield Bredning Fjord, Northwest Greenland; Oct 2022 - Jul 2023).

Please note that the first half of this dataset (Part A; specifically, data for Aug-Sep 2022 @ sensor #6229; Aug-Nov 2022 @ sensor #6230) is available at:

Description of the data and file structure

For recording sound, Soundtrap#6229 was deployed near the calving front of Bowdoin Glacier (77.67 deg N, 68.63 deg W; water depth = 192 m). The sound recorder was programmed to store 4.5 minutes of continuous sound every 20 minutes at a sampling rate of 64 kHz.

Zipped acoustic data is stored in standard audio files (e.g., 6229.220806030000.wav), which corresponds to a recorder's serial number and UTC time stamp (XXXX.YYMMDDHHmmss.wav).

Our data are structured in the following way:

BowdoinCalFr_6229.zip

The archive contains all audio files (6229.*.wav) recorded between October 2022 and July 2023 by Soundtrap#6229 at Bowdoin Fjord (see "Part A" for August - October 2022). For example,  the data set includes a series of files:

6229.221001000000.wav

6229.2212..................wav

6229.2301..................wav

6229.230802010000.wav

where "6229" is the serial number of the used Soundrtap hydrophone separated by a dot (.) from a corresponding time stamp information, interpreted as, e.g.,

"221001000000" = 10 October 2022, 00:00:00 UTC.

Each individual audio data file contains 4.5 minutes of acoustic amplitudes [in units re. Pa].

Code/Software

Acoustic data files *.sud were converted to *.wav using the free software SoundTrap Host (Release 4.0.17), which is offered at http://oceaninstruments.co.nz/downloads/(opens in new window). Data processing and visualizations were made with commercially available Matlab R2022b, Kaleidoscope Pro 5.6.2, and Raven (Lite 2.0 is openly available).
