Dataset developed as part of the with the Pacific Island Groundwater and Future Climates: First-Pass Regional Vulnerability Assessment.

An index of indicators of potential structural change of islands due to meteorological and oceanographic processes in the Pacific. This map was derived using island variables such as lithology, area, maximum elevation and circularity. This index helps to quickly identify islands most susceptible to environmental change. Map 2 of 3.

Map showing islands in the Pacific categorised into eight broad types: composite high, composite low, limestone high, limestone low, volcanic high, volcanic low, continental and reef island. A 30m cut-off was used between high and low islands. Map 1 of 3.

Map showing the geomorphic sensitivity of islands in the Pacific region to climate change. Map 3 of 3.

An earth-science-based classification of islands within the Pacific Basin resulted from the preparation of a database describing the location, area, and type of 1779 islands, where island type is determined as a function of the prevailing lithology and maximum elevation of each island, with an island defined as a discrete landmass composed of a contiguous land area ≥1 ha (0.01 km2) above mean
