NASA’s DopplerScatt Radar to Benefit Weather and Climate Studies, Maritime Uses

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Ocean currents and winds form an endless feedback loop: winds blow over the ocean’s surface, creating currents there. At the same time, the hot or cold water in these currents influences the wind’s speed.

This delicate dance is crucial to understanding Earth’s changing climate. Gathering data on this interaction can also help people track oil spills, plan shipping routes and understand ocean productivity in relation to fisheries.

Instruments already exist that measure ocean currents, and others that measure wind, such as NASA’s QuickScat and RapidScat. But a new, airborne radar instrument developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, is able to measure both.

NASA uses Aircraft mounted instruments to examine growing Deltas in Louisiana

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Louisiana coastline is sinking under the Gulf of Mexico at the rate of about one football field of land every hour (about 18 square miles of land lost in a year). But within this sinking region, two river deltas are growing. The Atchafalaya River and its diversion channel, Wax Lake Outlet, are gaining about one football field of new land every 11 and 8 hours, respectively (1.5 and 2 square miles per year).

Last fall, a team from NASA’s Jet Propulsion Laboratory in Pasadena, California, showed that radar, lidar and spectral instruments mounted on aircraft can be used to study the growing deltas, collecting data that can help scientists better understand how coastal wetlands will respond to global sea level rise.

The History of Renfroe Station on the Red River, 1780 – Part 2

 

Clarksville Tennessee HistoryClarksville, TN – In 1780 a group of 300 daring pioneers decided to journey upon the Tennessee River and the Cumberland River in flatboats and canoes.

The destination for some of them would be present day Montgomery County, upon the Red River at the mouth of Passenger Creek. Yet, in order to arrive at their destination they had to guide their boats through a frontier full of Native Americans determined to attack them.

Why would they attempt such an endeavor which seemed to almost promise violence, deprivation, and other hardships?

NASA Survey discovers extensive coastal erosion from Gulf Oil Spill

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Dramatic, widespread shoreline loss is revealed in new NASA/U.S. Geological Survey annual maps of the Louisiana marshlands where the coastline was most heavily coated with oil during the 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico.

Following the spill, the length of shoreline that receded more than 13 feet (4 meters) a year quadrupled compared to the year before the spill. The land losses occurred mainly in areas where oil had washed ashore during the spill.

Riding the Natchez Trace Parkway

 

Natchez Trace ParkwayTupelo, MS – The Natchez Trace, also known as “Old Natchez Trace,” is a 440 historic forest trail that links the Cumberland River, Tennessee River and Mississippi River.  The trail was used by Native Americans and later, by European and American Explorers.

Today, the Natchez Trace Parkway and bridge, commemorates the path used by early explorers.

It’s a recreational favorite among bikers, bicyclists, hikers, campers, boaters and just about anyone who enjoys the great outdoors, surrounded by incredible history.

NASA uses Airborne Radar to study sinking rate of New Orleans

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New Orleans and surrounding areas continue to sink at highly variable rates due to a combination of natural geologic and human-induced processes, finds a new NASA/university study using NASA airborne radar.

The observed rates of sinking, otherwise known as subsidence, were generally consistent with, but somewhat higher than, previous studies conducted using different radar data.

The research was the most spatially-extensive, high-resolution study to date of regional subsidence in and around New Orleans, measuring its effects and examining its causes.

Subsidence in Jefferson Parish, Louisiana, from June 2009 to July 2012, as seen by NASA's UAVSAR instrument. The measured displacements are a combination of movement of the ground and of individual structures. The inset at lower right shows the parish location within Greater New Orleans.
