Title: Water quality instrumentation in tidal waters
Author: N. Babbedge
Document Type: Monograph
Abstract:
Water quality monitors are used extensively by the Tidal Waters Investigation Unit which operates in the Water Quality Planning Section of the Environmental Protection Department. The unit currently uses, or is developing the use of, monitors for use in three types of application: i. Portable hand-held monitors for obtaining spot values in shallow to medium depth water (0 - 20m); ii. Multi-parameter units for continuous near-surface monitoring, either static (i.e. fixed location) or dynamic (from a moving vessel); iii. Multi-parameter units for continuous monitoring at depth or remote from the shore. All three types of monitor can be used for obtaining water quality profiles. The hand-held monitors are the most frequently used at present, primarily because they are simple to operate, reliable, and give good results. The two types of recording multi-parameter instrument are at different stages of appraisal, and are not yet routinely used.
