Tsunami sand deposit at Nilaveli Beach on the northeastern coast of Sri Lanka following the December 26th, 2004 earthquake and tsunami in the Indian Ocean. The sand deposited by the tsunami is light colored and overlies a pre-tsunami darker sandy soil.

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.

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).

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.

Lab setup aboard R/V Gyre in the Gulf of America from the 2003 field season. Computers, recorders, and other electronic gear are securely mounted in racks or on tabletops and shelving for stability in rolling seas and for access.

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.

Map showing the paths that ocean current-following surface drifters deployed in coral larval slicks off west Maui traveled in 24 hours following their release during a coral spawning event. Such data suggests that the coral reefs off west-central Maui may provide coral larvae to the reefs off northeastern Lānaʻi.

Underwater photograph of larvae being released into the water column from reef-building coral spawning off Maui the night of June 30, 2003. The white larvae are about 0.5 to 1.5 mm across.
