| Damage from tropical cyclones can have major consequences for coral reef structure and ecology, as well as for human communities and human uses of coral reef resources. Remote sensing with high resolution multispectral satellite images can be used to asses large scale cyclone damages on coral reef areas. SPOT images of the almost atoll of AITUTAKI (Cook Islands) taken in june 1986 and february 1987 after the passage of Cyclone Sally near the island in january, were transformed and subjected to a textural analysis, and then compared to asses damage on the reefs and lagoon.New shallow sand and rubble deposits showed increased reflectance, while lower reflectance seemed associated with damage to reef structure, scouring in the lagoon, deposits of terrestrial... |
