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 (66S - 140E) and the Italian and French base Concordia (75S - 123E). 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. One hundred nine (109) measurement series spanning 15 days were acquired at Dumont D'Urville and at sea.
Mr. Yann Courcoux from L'Observatoire de Physique de l'Atmosphere de la Riunion (OPAR) at the Universiti de la Riunion/ CNRS (Saint Denis de la Riunion, France) was the Principal Investigator for aerosol optical measurements and assured data collection at sea.
