Pourquoi Pas ? (English: Why Not?) is a research vessel built in Saint-Nazaire, France by Alstom Marine[1] for IFREMER and the French Navy[2] and primarily used by Service hydrographique et océanographique de la Marine (SHOM).[3] Pourquoi Pas ? was ordered in December 2002 and completed in July 2005.[4] The 66 million euro cost was financed by IFREMER (55%) and the French Navy (45%).[5]
Name
She is named after explorer Jean-Baptiste Charcot's famous ship.[4] A space is required immediately before a question mark in French orthography, and accordingly, in French Pourquoi Pas ? is the correct way to write the name.
Use
Pourquoi Pas ? is used on average 130 days per year by the French Navy and the rest by IFREMER.[3] It was designed for hydrography, geoscience, and physical, chemical, and biological oceanography, as well as to launch small submarines such as the crewed submersible Nautile and the ROV Victor 6000.[4] Since 2010, the ship has been used in a series of annual cruises MoMARSAT maintaining the EMSO-Azores observatory at the Lucky Strike hydrothermal field.[6][7]
Notable missions
Pourquoi Pas ? has been used for the 2007 deployment and connection operations for the ANTARES neutrino telescope.[8] In 2008, Pourquoi Pas ? was used for the initial testing and operations of the PERISCOP, a pressurized deep sea fish recovery device.[9] In June 2009, she was used to assist the recovery of Air France Flight 447.[10][11] In November 2020, the ship was used to find the wreckage of an Aquilon fighter jet that had disappeared in June 1960.[12] In April 2024, scientists on board the Pourquoi Pas ? discovered 6 new seamounts in the North Pacific off Mexico.[13]
