A severely damaged home, or a portion of one, sits atop debris in Banda Aceh on the island of Sumatra. Damage was caused by a massive, highly destructive tsunami, triggered by a magnitude 9.1 earthquake just offshore of Sumatra, on December 26, 2004.

The USGS studied air photos of the Big Sur coast taken in 1942 and 1994, in cooperation with the California Department of Transportation (Caltrans) and the University of California at Santa Cruz (UCSC).

The USGS, in cooperation with Moss Landing Marine Laboratory, mapped the slopes of the Santa Barbara Channel using sonar. We combined this with deep sea drilling records and seismic records to make these maps.

Here are shown a series of photographs of a rice coral (Montipora capitata) shaded with light filters during a natural “coral bleaching” event observed during anomalously high ocean temperatures in Autumn of 2004 on the island of Oʻahu, Hawaiʻi.

The Great Barrier Reef arches over 2000 kilometers along the northeast coast of Australia. The white calcium carbonate that coats the coral reflects light, making the water above the reef appear bright blue from space.

Airborne lidar is a surveying method that measures distance to a target from a survey plane by illuminating that target with a pulsed laser light, and measuring the reflected pulses with a sensor. Differences in laser return times and wavelengths can then be used to make digital 3D-representations of the target.
