NASA Sees Hurricane Charley Slice a Florida Island

13.10.2005


Hurricane Charley came ashore on the southwest coast of Florida as a Category 4 hurricane on Friday, Aug. 13, 2004, and changed the look of North Captiva Island.



The U.S. Geological Survey (USGS), NASA and the U.S. Army Corps of Engineers are studying the effects of Charley as part of a cooperative research project investigating coastal change.

The USGS Coastal and Marine Geology Program investigates the extent and causes of coastal impacts of hurricanes and extreme storms on the coasts of the United States. The program’s overall objective is to improve the capability to predict coastal change that results from severe tropical and extra-tropical storms. Such a capability will facilitate locating buildings and infrastructure away from coastal change hazards.


On Aug. 15, aerial video and still photography were acquired from Venice to Marco Island, Fla. On Aug. 16, NASA’s laser mapping system called EAARL (Experimental Advanced Airborne Research Lidar), measured ocean depths and the topography of the ocean floor and the coast.

The data were compared to an earlier survey conducted in June 2004 by the Army Corps of Engineers using CHARTS (Compact Hydrographic Airborne Rapid Total Survey) to detect the magnitude and spatial variability of coastal changes such as beach erosion, overwash deposition and island breaches. The data will also be used to develop and test computer models that will predict coastal impacts from severe storms. It will be made available to local, state and federal agencies for purposes of disaster recovery and erosion mitigation.

"They are trying to better understand how hurricanes or Nor’easters impact coastal environments," said C. Wayne Wright, remote-sensing scientist at NASA Goddard’s Wallops Island Flight Facility, Wallops Island, Va.

This is a joint project with NASA, the USGS and the Army Corps of Engineers. The partners are using this to measure beach face changes as a result of severe storms.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
