International audience TRISTAN (TRasgo para InveSTigaciones ANtarticas) is a cosmic ray detector of the TRASGOfamily. The detector has been installed at the Spanish Antarctic Base in Livignston Island, as oneof the detectors of ORCA (Antarctic Cosmic Ray Observaroty) in December 2019. TRISTANdetector collected data during three journeys crossing the Atlantic Ocean between latitudes 38ºNand 53ºS on board of the Sarmiento de Gamboa and BIO Hesperides oceanographic vessels. Thetrips took place between November 2018 and December 2019. The main purpose is to evaluatethe capability of a TRASGO detector to explore the geomagnetic field variations and the differentatmospheric behaviours at both hemispheres and in the Equator region. The main technical aspectsof the detector and its performance (efficiency, resolutions, and acceptances) will be discussedand the preliminary results of the last journey will be presente
