Study-Unit Description


TITLE Instrumentation for Environmental Measurements

LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course


DEPARTMENT Geosciences

DESCRIPTION This study-unit will introduce the students to the actual instrumentation used in environmental and oceanographic measurements, and provide them with hands-on experience of such instrumentation. It will cover the theoretical basis of how the instruments operate as well as the practical use of such instruments, with site visits where possible.

Study-unit Aims:

This study-unit aims to familiarise students with instrumentation and methods of analysis used in atmospheric and oceanographic sciences. It aims to provide the students with a proper understanding of the physical and chemical principles of measurement used, besides introducing them to the actual instruments through the use of site visits and field work.

Learning Outcomes:

1. Knowledge & Understanding
By the end of the study-unit the student will be able to:

- recall the principles on which these instruments are based;
- describe the method of operation of these instruments;
- describe the kind of data that is produced by each instrument;
- discuss the sensitivity of the various instruments;
- appreciate the requirements of particular investigations and which instruments/tools are to be used;
- use these instruments in the laboratory and field.

2. Skills
By the end of the study-unit the student will be able to:

- handle and use these instruments in the laboratory and field;
- carry out actual measurements, and extract the relevant data;
- evaluate data sets from these instruments and interpret same.
