The mission of the Geomagnetism Program is to monitor the Earth's magnetic field.
Gas Hydrates - Primer
What is Gas Hydrate?
Gas hydrate is an ice-like crystalline form of water and low molecular weight gas (e.g., methane, ethane, carbon dioxide). On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost. Gas hydrates have also been inferred on other planets or their moons.
At the molecular level, gas hydrate...
Hurricane Sandy Response - Storm Impacts and Vulnerability of Coastal Beaches
Scientists evaluated and improved the accuracy of pre-landfall forecasts of storm-induced coastal erosion hazards for Northeast beaches using data from post-Sandy lidar sruveys, beach morphology, and storm hydrodamics.
Hurricane Sandy Response - Barrier Island and Estuarine Wetland Physical Change Assessment
This project integrated a wetland assessment with existing coastal-change hazard assessments for the adjacent dunes and beaches of Assateague Island, Maryland, to create a more comprehensive coastal vulnerability assessment.
Coral Reef Seafloor Erosion and Coastal Hazards
Synchronized field work focused on geochemistry, geology, and metabolic processes overlaid on a habitat map of an entire reef to produce a synoptic overview of reef processes that contribute to carbonate precipitation and dissolution.
Hawaii Tsunami Messaging
Recent scientific study reveals that certain large earthquakes in the Aleutian Islands can produce much greater tsunami inundation than Hawaii typically experiences. This higher level of tsunami inundation necessitates changes to current tsunami safety instructions - but only for this Aleutian event.
