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: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
