RV Alpha Crucis

Alpha Crucis is the most recent oceanographic research vessel in Brazil, replacing the older Wladimir Besnard research vessel. It is named after the star that represents São Paulo state in the Brazilian flag. It is 64 meters long and 11 meters wide, and has capacity for 25 researchers and 15 and is capable of remaining 40 days without being resupplied.

The vessel was built in 1974, and was originally called Moana Wave. It was firstly owned by the University of Hawaii. In 2010, the Foundation for Research Support of the State of São Paulo has funded the acquisition of the Alpha Crucis after a fire in 2008 rendered the RV Wladimir Besnard inoperant. It is now administered by the University of São Paulo.

The vessel is being used for several research projects in Brazil, in topics such as global climate change and biodiversity.
