Tethys is a system for organizing and retaining information from passive acoustic monitoring efforts. We enable the retention and querying of information related to deployments of acoustic data loggers and their characteristics (e.g. sample rate, calibration functions) and information related to the detection and location of sounds within the recording. While our focus is on marine mammals, the work is applicable to a wide variety of passive acousitc monitoring problems.
While details on the system are available in the documentation as well as some of our publications, a twenty-five minute overview video of Tethys can provide potential users with knowledge about the types of things that Tethys can do.
Starting with the Tethys 2.5 release, we have introduced a graphical interface to Tethys that runs in a web browser. It supports both novice and expert query modes. While we still recommend programmatic interfaces for large-scale analysis, the web client enables novice users to perform data exploration as well as ways to export the data into programs such as R and MATLAB for analysis.
