Unit of Competency NWPHYS007 - Use underwater acoustics to map waterways
Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to use underwater acoustics to map waterways.It includes applying acoustic theory and using single beam, side scan sonar and swath echo sounders. It also includes using sonar systems, reviewing and reporting results and understanding the differences between the different methods. This unit supports the attainment of skills and knowledge required for leaders with responsibility for performing hydrographic surveying and may lead to certification as a hydrographic surveyor.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
