This document describes the HydrOffice Sound Speed Library and Manager (2019.2). For the source code, go here.

2.4.1.2. Database Tab

The package provides functionalities to permanently store, delete and retrieve the sound speed profiles. Any time that a profile is exported or transmitted, its data content is stored in the database. A profile can also be stored in the database by using Save to database in the Editor toolbar (Fig. 2.40).

In particular, each profile contains three types of stored data:

  1. The raw data (which makes it possible to redo the processing from scratch).

  2. The processed samples (with flags to identify the different sources of data).

  3. An optional SIS profile (that represents the result of the thinning process required by Kongsberg SIS).

Once stored in the database, the Database tab provides analysis functions and tools to manage the collected profiles (Fig. 2.41).

2.4.1.2.1. Context menu

The context menu provides access to different tools based on the number of selected profiles:

single selection

Fig. 2.42 The single-selection context menu provides functionalities specific to a single profile.

pair selection

Fig. 2.43 The pair-selection context menu provides functionalities like ray-tracing comparison (Fig. 2.44) and bias plots (Fig. 2.45).

bias plots

multi selection

Fig. 2.46 The multi-selection context menu provides functionalities that apply to multiple profiles (e.g., editing common metadata fields for multiple profiles).

2.4.1.2.2. Project and Profiles groups

The Project group provides functionalaties to:

  • Create a new project (New project button).

  • Rename an existing project (Rename project button).

  • Switch among existing projects (Switch project button).

  • Import data from an existing database to the current project (Import data button).

  • Open the folder that contains the project databases (Open folder button).

From the Profiles group, it is possible to import (Import profiles button) or export (Export profiles button) multiple profiles.

Using the Make plots and Export info buttons (Fig. 2.47), you may:
