Ice Profiler TM Processing Toolbox and User Guide

In response to our customers, we developed the IPS Processing Toolbox and User's Guide. (applicable for all IPS4 & IPS5 data) Features List ~ Licensed Copy ~ System Requirements ~ Toolbox Routines ~ Further Details **Now available ** - easier to use Graphical User Interface(GUI) routines with improved documentation for processing Ice Profiler data sets. The included User's Guide gives an in depth set of instructions for the sequence of processing steps as well as some technical discussions on the theoretical rationale of resolving ice drafts acoustically. (Click here for a more detailed description of the IPS Toolbox and User's Guide) Presently, the toolbox requires MATLAB and can be run either through the Graphical User Interface or through the MATLAB command line. ** Coming soon** - development is underway to create a stand-alone version of the toolbox which does not require MATLAB. Software Feature List Designed to process ASL Ice Profiler data from start to finish, Routines for removal of noisy data: ie. automated and interactive methods for despiking, smoothing, cropping and interpolation, Automated and interactive methods for corrections of sound speed variations, Headers automatically document processing steps, Data viewer now available to plot and compare time series data sets, Ability to save parameter settings, Online help for use of programs. Screenshot of data visualization routine displaying smoothed and raw unsmoothed data. Screenshot example of Graphical User Interface panel. How to Obtain a Licensed Copy Customers may purchase a licensed copy for US$ 1,900, which will include software support available by telephone or email for 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. A four day training course at ASL Environmental Sciences is available upon request. Customers who took training courses with ASL will also be offered reduced rates on future software assistance. Contact us for details. Email: asl@aslenv.com System Requirements An IBM PC or compatible with at least 500 MHz CPU or higher processor. Minimum of 256 MB of RAM. 1024x768 SVGA or higher. Microsoft Windows. CD-ROM for software installation. MATLAB  version 7 or higher is required. IPS4 & IPS5 data processing typically use up to 5 Gb & 20 Gb of hard drive space, respectively. A backup device is recommended for routine backups of processed data files.

The successful processing and analysis of IPS 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 IPS data and the reader may find that she/he may wish 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 the User's Guidel 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 the User's Guide to aid in familiarizing oneself with the software. Regular upgrades and improvements are made to the ASL IPS Processing Toolbox and your feedback is very important.
