Ice Profiler Processing Toolbox
and User's Guide

User's Guide Overview
Examples of Graphical User Interface (GUI) routines

 

In response to our customers, we at ASL Environmental Sciences have developed the IPS Processing Toolbox and User's Guide.

** Now available ** - easier to use software and
improved documentation for processing Ice Profiler data sets.

The User's Guide gives step-by-step instructions. This is an alternative to the 4-day training course offered at ASL Environmental Sciences.

All existing software programs were modified to use Graphical User Interface (GUI) routines to make operating the programs much easier.

A set of new programs has been added to the Toolbox as well:

  • Automated and interactive methods for corrections for variations in sound speed (beta correction)
  • Automatic creation and manual editing of header files
  • Ability to save settings
  • Online help for use of programs

The purpose of this user's guide is to enable users of the ASL IPS Processing Toolbox to develop appropriate procedures for processing IPS4 data. The successful processing and analysis of IPS4 data requires a solid understanding of the instrument itself and of the physics of underwater acoustic and oceanographic processes.

In this user's guide, a detailed suite of MATLAB based software tools are described with instructions and examples of their use. The key features of the IPS instrument are also described, as well as explanations of the relevant physical oceanographic processes, which the software tools are applied to.

Customers may purchase a licensed copy for US$ 1,900, which will include software support available by telephone or email for the the first year for a maximum of 8 man-hours per year. The assistance service can be obtained at a cost of US$ 450 in the future.

Past customers who took training courses with ASL will be offered reduced rates. Contact us for details. Email: asl@aslenv.com

For more details of the User's Guide and examples of the Graphical User Interface - see below.

 

Ice Profiler Processing Toolbox and
User's Guide Overview

The purpose of this user's guide is to enable users of the ASL IPS Processing Toolbox to develop appropriate procedures for processing IPS4 data. The successful processing and analysis of IPS4 data requires a solid understanding of the instrument itself and of the physics of underwater acoustic and oceanographic processes.

Although this manual recommends a processing method it is by no means restrictive. There are many ways to process IPS4 data and the reader may find that she/he wishes to alter or append to the methods suggested in this document. The optimal data processing and analysis approach may depend on such factors as:

  • the sea-ice and oceanographic regime of the study area;
  • platform (e.g. bottom moored or AUV) dependent issues;
  • the available computer environment and resources.

A sample data set is used throughout this manual so that the reader may observe the various stages of the processing procedure.

The majority of the programs contained in the ASL IPS Processing Toolbox have graphical interfaces for ease of use. When necessary, images of these graphical interfaces appear throughout this User's Guide to aid in familiarizing yourself with the software. Regular upgrades and improvements are made to the ASL IPS Processing Toolbox and your feedback is very important to make this process effective.

 

Examples of Graphical User Interface (GUI) routines

1. Computation of uncorrected ice draft time series

To find areas of open water to be used in calculating range correction factors (in particular, small openings in the ice), it is very helpful to have an expanded zoomed-in ice draft time series.

2. Automated detection and removal of erroneous or suspect data

ASL_Despike automatically detects and linearly interpolates over spikes of various sizes within the data.
