Overview

This package contains Python utilities for interacting with the popular ocean acoustics modeling software, Acoustics Toolbox (AT), developed and maintained by Mike Porter. Code in this package has been adapted primarily from:

• Hunter Akins' PyAT
• Aaron Thodes' MATLAB scripts for interacting with AT.

Current functionality includes:

• KRAKEN (normal modes)
• Basic transmission loss plotting.
• Basic signal processing functions.

Future intended functionality:

• Bellhop (ray tracing)
• Additional plotting functions
• IO functions for reading in experimental data.
• Robust signal processing workflows (e.g., matched field processing)

Setup

Prerequisites

1. Install Acoustics Toolbox (Mac users).

Installation

TritonOA can be built directly from source or installed using pip.

Build from source:

1. Open a terminal and navigate to the desired installation directory.
2. Save TritonOA.yml to the directory by running:
   a. MacOS:
   curl -LJO https://raw.githubusercontent.com/NeptuneProjects/TritonOA/master/TritonOA.yml
   b. Linux:
   wget --no-check-certificate --content-disposition https://raw.githubusercontent.com/NeptuneProjects/TritonOA/master/TritonOA.yml
3. In Terminal, run:
   conda env create -f TritonOA.yml
4. Once the environment is set up and the package is installed, activate your environment by running:
   conda activate TritonOA

Using pip:

1. In a virtual environment, run:
   pip install git+https://github.com/NeptuneProjects/TritonOA.git

Usage

A Jupyter notebooks illustrating use cases is provided in the tutorials folder.
