Following tag deployment in September 2021 Andromeda and her calf stayed in the northern area of Golfo Nuevo. Their exact departure from Península Valdés is unknown as contact was lost with them temporarily and then recovered when they were already in the ocean basin, having crossed the continental shelf.

After exploring the deep waters off the central continental shelf, Andromeda and her calf traveled southwards. At the end of January 2022, they crossed the arc of the Austral Antilles, 300 kilometers east of the Banco Namuncura-Burdwood and continued across the Scotia Sea to the Islas Orcadas del Sur (South Orkney Islands).

From there they traveled to the Antarctic seas, where between February and May 2022, they explored the Mar de Weddell (Weddell Sea) north of the Antarctic Peninsula. They then returned to the Mar de Scotia (Scotia Sea). Contact was lost with Andromeda son June 8, 2022, when she was between the Islas Orcadas (South Orkneys) and the southernmost tip of the Islas Sandwich del Sur (South Sandwich Islands’) archipelago.

Andromeda’s satellite transmitter provided information about her migration for 254 days over 12,344 kilometers (7,670 miles). Of all the whales tracked during this project, Andromeda broke the record of travels farthest south: she crossed latitude 66°S.
