Los Angeles, Feb 20 (UNI) Delta-X, a new NASA airborne investigation, is preparing to embark on its first field campaign in US Mississippi River Delta in coastal Louisiana state, according to a release of NASA's Jet Propulsion Laboratory (JPL).

Beginning in April, the Delta-X science team, led by Principal Investigator Marc Simard of JPL, will be collecting data by air and by boat to better understand why some parts of the delta are disappearing due to sea-level rise while other parts are not, the release said on Wednesday.
