The PIRATA FR32 cruise in February-April 2022 on the R/V Thalassa

The last PIRATA cruise is currently taking place from 22 February to 9 April 2022 from Las Palmas to Las Palmas aboard the R/V Thalassa with the swap of 6 moorings including 3 T-FLEX in the Gulf of Guinea.

Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) is a multinational program initiated in 1997 in the tropical Atlantic to improve our understanding and ability to predict ocean-atmosphere variability. PIRATA consists of a network of moored buoys providing meteorological and oceanographic data transmitted in real time to address fundamental scientific questions as well as societal needs.

The network is maintained through dedicated yearly cruises, which allow for extensive complementary shipboard measurements and provide platforms for deployment of other components of the Tropical Atlantic Observing System.

This paper describes network enhancements, scientific accomplishments and successes obtained from the last 10 years of observations, and additional results enabled by cooperation with other national and international programs.

Capacity building activities and the role of PIRATA in a future Tropical Atlantic Observing System that is presently being optimized are also described.

New: the story of the PIRATA rise

The rise of PIRATA 1995-2005


The PIRATA project is a joint effort between Brazil, France and the United States to collect oceanic and meteorological observations in the tropical Atlantic.

The experimental program PIRATA (initially « Pilot Research moored Array in the Tropical Atlantic » and named « Prediction and Research Moored Array in the Tropical Atlantic »  from 2008) has been implemented in 1997 in the Tropical Atlantic Ocean (Servain et al. 1998). It has been launched in the framework of the international program CLIVAR (CLImatic VARiability and predictability) and implies scientific teams from three countries: France (IRD, in charge of coordination and oceanic cruises, Météo France, with contributions by IFREMER and CNRS/INSU), Brazil (DHN and INPE) and USA (NOAA/PMEL). Financial supports for the program are from the IRD, Météo France, and Observatoire Midi-Pyrénées/Université Paul Sabatier.


French PIRATA cruises DOI informations

From early 2016, informations about all PIRATA-FR cruises have been made available through a "DOI" (Digital Object Identifier) 10.18142/14 through the French Oceanographic Portail.

Each PIRATA-FR cruise has it own DOI number. Each DOI gives access to cruise information, data sets, publications, etc...
