Elephant and weddell seals in Antarctica have been equipped with satellite transponders for researching their travel and eat behaviour. During such a campaign our client from Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung was in the polar regions for several months to equip marine mammals. Meanwhile we continuously retrieved navigation data from those transponders, post-processed data and informed our client in field about the recent state. After his campaign we regularly provided track charts and in the end compiled all data to be delivered to the longterm data archive www.pangaea.de.
