Project implementation of Pacific HYCOS activities in Tonga had been delayed since Oct
2008 due to difficulties within MLSNR to obtain operational budget and support for proposed
monitoring activities. It had been proposed that MLSNR undertake the regular joint
monitoring activities proposed for Mataki’eua and develop water resource analysis and
reporting skills as well as make improvements to the existing database including inclusion of
paper records and review identified anomalies as well as backup to Tideda.
This chapter provides a brief description of Tonga, its past and present climate as well as projections for the future. The climate observation network and the availability of atmospheric and oceanic data records are outlined.
This report describes the drilling program undertaken during November and December 1997 in the
Pangai – Hihifo and Koulo areas on the island of Lifuka. The purpose of the program was to:
* install seven water salinity monitoring boreholes;
* provide additional training for the Ministry of Works (MOW) drilling crew in the methods used in
the installation of the monitoring system used in this program; and
* instruct the local Tonga Water Board (TWB) staff in monitoring procedures.
