Eos´s tracking route

  • In these last few days Eos traveled 700 kilometers (435 miles) eastward over the Scotia Arc, reaching the edge of the submerged plateau of the Islas Georgias del Sur (South Georgia).

  • Eos continues holding the 2023 season record as the whale that has traveled the farthest (11,235 kilometers; 6,981 miles). After entering the deep ocean basin, she backtracked to her previous location over the Malvinas (Falkland) plateau, east of the islands. Artemisa and Persefone are in the same area, suggesting that the waters over that section of the continental shelf are highly productive.

  • Eos continues to be the whale which has traveled farthest since being tagged, having covered more than 10,700 kilometers (6,649 miles) during her 83 days tracked. She has now left the waters over the Malvinas shelf and entered the deep ocean basin.

  • Eos continued southwards in the deep ocean basin, circled the submerged Maurice Ewing plateau of the Malvinas (Falklands), and is now approaching the Scotia Arc, 300 kilometers northeast of the Islas Georgias del Sur (South Georgia). Eos has thus far traveled about 6,000 kilometers (3,728 miles).

  • Eos is an adult female who, with her calf, traveled the coastal waters between Punta Cormoranes and Morro Nuevo, close to the mouth of the gulf. Almost one month after deployment of her satellite transmitter, on November 22, Eos and her calf began their migration traveling directly to the Blue Hole. They crossed the continental slope and are now exploring the deep ocean basin.
