The Astrolabe supply ship belongs to P&O Maritime services. This Ice Class, multipurpose support vessel is operated for the French Government's Institut Polaire Francais Paul Emile Victor (IPEV) to supply the French polar base Dumont d'Urville (66䓨'S - 140䓁'E) and the Italian and French base Concordia (75䓆'S - 123䓕'E). Each year the ship transports staff and freight between Hobart (Tasmania) and Dumont d'Urville and operates in support of oceanographic research programs conducted by the French Polar Institute. Two hundred seventy two (272) measurement series spanning 30 days were acquired at Dumont D'Urville and at sea.
Mr. Yann Courcoux from L'Observatoire de Physique de l'Atmosphere de la Réunion (OPAR) at the Université de la Réunion/ CNRS (Saint Denis de la Réunion, France) was a Principal Investigator for aerosol optical measurements and assured data collection at sea.
