Safe navigation gets boost in region

The safety of navigation and the protection of the marine environment in the region took a positive step forward recently with the signing of a Memorandum of Understanding between the International Hydrographic Organization (IHO) and Secretariat of the Pacific Community (SPC). Hydrography is the study, surveying, and mapping of the oceans, seas and rivers, especially related to navigation and the environment.

IHO is comprised of 80 member governments represented by their respective national hydrographic offices.  Its objectives include the standardization of nautical charts as well as the adoption of reliable and efficient methods to conduct hydrographic surveys.

The purpose of the MOU is to provide a framework for cooperation between the IHO and SPC to support the efficient and effective development and coordination of hydrographic and nautical charting programmes for Pacific island countries and territories.
This is in accordance with the requirements of international treaty obligations.

Dr. Russell Howorth, Director of SOPAC, a Division of SPC, said that the agreement would be of substantial value to the region.
“SOPAC has been developing bathymetry charts, by measuring the depth of oceans and seas, for many years, but IHO is the only organization that can officially stamp charts as suitable for navigation,” said Dr. Howorth.

Additionally the MOU is to promote the widespread use of hydrographic data collected by the two organisations or their members for the benefit of safety of navigation and life at sea, protection of the marine environment, national infrastructure development, coastal zone management, marine exploration and resource exploitation, maritime boundary delimitation and policing, maritime defense and security, and natural disaster management.

Thursday 19 September 2013, Secretariat of the Pacific Community (SPC), Suva, Fiji – On 19 September, guest lecturer Dr. Tom Durrant of the Australian Bureau of Meteorology presented his wave modelling research to students at USP Marine Science Campus. This new research provides a better understanding of ocean wave movements across the Pacific and will be used by SPC’s Applied Geoscience and Technology (SOPAC) Division to enhance development planning and disaster management in the region.

According to Durrant, “Waves and wave climate have significant implications for coastal security, marine resources, and alternative energy options. Waves on the ocean, Durrant explained, range in period from tidal waves, with periods of 12 and 24 hours, to Tsunamis, with periods around 15 minutes, to wind driven waves with periods of around 2 to 20 seconds.

In the case of wind driven waves, the focus of Durrant's work,  the longer the wind blows over a greater area, the bigger the waves. Pacific Islands are affected not only by local, short period, wind-generated waves but also by long period swells generated by far away storms.

Long period swell waves are fast-moving waves caused by distant storms that can pile up when they reach land. Such waves have caused widespread flooding, damage and loss of life in the Pacific, for example, in the Mortlock Islands of Papua New Guinea in 2009 and in the Marshall Islands in 2012. “These events haven’t been studied much because of lack of data,” said Durrant.

To this end, Durrant has been working under the AusAid-funded Pacific and Australia Climate Change Science and Adaptation Planning (PACCSAP) Programme to develop wave models for the Pacific that can in turn be used to assess wave-induced coastal inundation events in detail.
