Key facts
Contents & fields
The dataset description is stored in an Excel workbook with a summary sheet and multiple sonobuoy deployment data log sheets. The summary sheet has one line per deployment. Data log sheets are separated by start date. Each deployment has an initial entry and subsequent rows as a running log. Fields include:
- Observer(real time/post-processing)——Real-time or post-processing observer
- Summary of the sounds——Summary of sounds within the 70-minute sample
- Total recording length (in minutes)——Total recording duration in minutes
- Date——Date
- UTC time of deployment——UTC time of deployment
- Initial latitude (decimal degrees)——Initial latitude in decimal degrees
- Initial Longitude (decimal degrees)——Initial longitude in decimal degrees
- Depth setting of sonobuoy hydrophone (90, 120, or 300m)——Hydrophone depth setting
- National Instruments sound card gain (0, 5, or 10 times)——NI sound card gain
- Ship heading (true degrees)——Ship heading in true degrees
- Ship speed (knots)——Ship speed in knots
- Distance of deployment from CTD location (if applicable)——Distance from CTD station
Research uses
This data can support acoustic monitoring of marine mammals in the Southern Ocean, studies of species distribution and behavior, and development of sonobuoy data processing methods.

Why this is hard to get on your own
Marine mammal acoustic survey data are often difficult to reuse due to inconsistent acquisition procedures, processing workflows, and field structures. This dataset provides detailed acquisition and processing descriptions, but the license is not specified, requiring further confirmation of usage conditions.
