Tool: Sound Speed Manager (SSM)

Sound Speed Manager (SSM) aims to merge together functionalities present in three existing applications that process sound speed profiles (SSP) for underwater acoustic systems: NOAA Velocity, MAC SVP Editor, and HydrOffice SSP Manager.

Sound Speed Manager has been designed to ease integration into existing data acquisition workflows. The liberal open source license used by the project (specifically, GNU LGPL) provides for understanding of the chosen processing solutions through ready inspection of the source code, as well as the ability to adapt the application to specific organization needs.

This adaptation is eased by the modular design of the application, with the NOAA-specific functionalities organized so that they can be easily deactivated for non-NOAA users.

The main functionalities include: wide support of commonly-used sound speed profile formats, full integration with common data acquisition/integration applications (e.g., Kongsberg SIS), profile enhancement based on real-time and climatologic models, and database management of the collected data with built-in functionalities for analysis and visualization. With a long-term support and development plan, Sound Speed Manager is a turnkey application ready to be used (and extended) by professionals and institutions in the hydrographic community.

The application is jointly developed by the Center for Coastal and Ocean Mapping, UNH and NOAA Coast Survey Development Laboratory (CSDL).
Sound Speed Manager is written in Python 3, and the current release is 2017.2.0.
