Survey
Operations Support
The
Tidal Section determines datum levels for RAN Hydrographic
Service surveys, predicts and models tidal heights
for survey areas, monitors the acquisition of tidal
data during surveys using satellite telecommunication
with survey ships and tide gauges, and analyses
newly acquired data.

Accurate
charts cannot be compiled without tidal information.
The Tidal Section determines an appropriate Chart
Datum for every chart, supplies tidal and tide stream information for charts, and determines if
and where tidal stream information should be shown.
Tidal
Information Service
There
is a considerable demand for tidal information
- especially predictions. The range of requests
handled by the Tidal Section is diverse, supporting
such things as offshore resource exploration, scientific
study and general inquiries from the public. Simple
inquiries can often be addressed quickly and at
little or no charge. More complex inquiries or
access to certain tidal information will require
a formal request and may incur charges or the need
to take out a licence.
