The Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI) aims to provide the Pacific Island Countries (PICs) with disaster risk modeling and assessment tools. It also aims to engage in a dialogue with the PICs on integrated financial solutions for the reduction of their financial vulnerability to natural disasters and to climate change. The initiative is part of the broader agenda on disaster risk management and climate change adaptation in the Pacific region.
Environmental conditions and anthropogenic impacts are key influences on ecological processes and associated ecosystem services. Effective management of Tonga’s marine ecosystems therefore depends on accurate and up-to-date knowledge of environmental and anthropogenic variables. Although many types of environmental and anthropogenic data are now available in global layers, they are often inaccessible to end users, particularly in developing countries with limited accessibility and analytical training.
GEBCO's aim is to provide the most authoritative publicly-available bathymetry of the world's oceans. It operates under the joint auspices of the International Hydrographic Organization(IHO) and the Intergovernmental Oceanographic Commission (IOC) (of UNESCO).
GEBCO produces and makes available a range of bathymetric data sets and products. This includes a global bathymetric grid; gazetteer of undersea feature names, a Web Map Service and printable maps of ocean bathymetry.
Physical geography, biological, bathymetry, geomorphology, oceanography, uses, risks spatial data for Solomon Islands marine environment.

A high-resolution bathymetric mapping survey was conducted for the seabed surrounding the island of Efate in Vanuatu.The bathymetry chart contained here is the second part of the overall bathymetry chart produced for Efate Island in Vanuatu. This bathymetric map is a blend of multibeam (MBES), and singlebeam (SBES) echosounder data. All slope angles exceeding 60 degrees (degrees from horizontal) were interpreted as scarps. Any Inclined area of the seafloor that was laterally confined by distinctive slopes, with or without an upslope headscarp, was interpreted as a channel.
This record holds the Technical report describing a SOPAC Division marine survey carried out for Kiribati, on the islands of Abaiang, Tarawa, Abemama, Banaba and Onotoa.

This record holds the PDF format of the bathymetry chart of Forari Bay in Efate, Vanuatu. The chart shows the 3-dimensional bathymetry map of Forari Bay showing shallow to deep from red to blue. Two times vertical exaggeration. Chart is the result of high-resolution bathymetric mapping survey of the seabed surrounding Forari Bay in Vanuatu using a blend of multibeam (MBES), and singlebeam (SBES) echosounder data.

This report describes a high-resolution bathymetric mapping survey of the seabed surrounding the island of Efate in Vanuatu, by the Pacific Islands Applied Geoscience Commission
(SOPAC). The survey was carried out over a period of 25
days in August 2003, resulting in the acquisition of over 600 line kilometres of MBES data.
The resultant compilation was used to produce
bathymetry charts of Efate at scales of 1 : 100 000 and 1 : 50 000, with more detailed charts of
Mele Bay, Forari Bay and Havannah Bay at 1 : 20 000.

The Cooperative Study project on the Deepsea Mineral Resources in the Sea Area of the Kingdom of Tonga. This first year survey was carried out in the sea area within the exclusive economic zone of the Kingdom of Tonga, which is located in the middle east of the Lau Basin and has an area of about 36,000 km2.
