The samples travelled 1400km upstream from the Igarka permafrost museum to Krasnoyarsk Federal University. This is the end of the intensive sampling of the Ienisei. Thanks to every single people who helped in this initiative: Virginie, Marie-Jo, Annick, Stéphanie et l’équipe d’ULISSE, Elena (our special agent in Krasnoyarsk), the Geocryology Laboratory team and particularly Anatolii and Nikita. Finally a collective thank to Igarka people who helped in any way to make this sampling possible!
