, Port Mikkelsen bay, Trinity Island, one of the Palmer archipelago. It was inaugurated by the Argentine Navy on December 10th , 1954. Its original name was Port Mikkelsen Refuge.
In March 2017, it was renewed by a task force of the M/V ARA Bahía San Blas; a group of 6 Navy men remained for 8 days in the shelter making maintenance and replace spare parts until March 17, 2018.
On the evening of the first day of navigation in Antarctica, the M/V ARA “Bahía San Blas” anchored near Trinidad Island, where the Capitán Caillet Bois Naval Refuge is located, thus starting the operations of the final stage of the 2018 Antarctic Summer Campaign.
