About David W. Jourdan
- David Walter Jourdan (born December 5, 1954) is an author, founder of Meridian Sciences, and the co-founder and president of Nauticos, a deep ocean exploration company.
- He studied physics and engineering at the U.S.
- Naval Academy and Johns Hopkins University, and served as a U.S.
- Navy submarine officer during the Cold War.
- Jourdan and his Nauticos team have made a number of notable deep ocean discoveries, including the missing Israeli submarine INS Dakar in the Mediterranean and the Japanese aircraft carrier Kaga, sunk in the battle of Midway.
- Most recently he has led two deep ocean expeditions in search of Amelia Earhart’s lost Lockheed Electra airplane.
- He has published several books, Never Forgotten: the Search and Discovery of Israel's Lost Submarine Dakar; The Deep Sea Quest for Amelia Earhart.; and The Search for the Japanese Fleet: USS Nautilus and the Battle of Midway. He has claimed any transmissions attributed to Gardner Island (now called Nikumaroro) in the Phoenix Island Group were false.
- Through his company Nauticos he extensively searched a 1,200-square-mile (3,100 km2) quadrant north and west of Howland Island during two deep-sea sonar expeditions (2002 and 2006, total cost $4.5 million) and found nothing.
- The search locations were derived from the line of position (157–337) broadcast by Earhart on July 2, 1937.
- Nevertheless, Elgen Long's interpretations have led Jourdan to conclude, "The analysis of all the data we have – the fuel analysis, the radio calls, other things – tells me she went into the water off Howland."
