Costs and consequences of natural hazards can be enormous; each year more people and infrastructure are at risk. We develop and apply hazards science to help protect U.S. safety, security, and economic well being. These scientific observations, analyses, and research are crucial for the Nation to become more resilient to natural hazards.

IMMeRSS-- Geophysical Imaging for Methane Seep Studies

Geophysical imaging relies on specialized tools to detect anomalies in the water column or to map features on or beneath the seafloor.  Equipment may be towed, mounted on the side of a ship, or attached to the ship’s hull.  Many geophysical techniques rely on transmitting an acoustic signal of a particular frequency and analyzing the information in the returning signal to infer the properties...
