Eos´s tracking route

  • Eos remains over the plateau of the Islas Georgias del Sur (South Georgia). After more than three months almost stationary in an area southeast of the archipelago, she began moving westwards, coming ever closer to the steep coasts of the largest island.

  • Eos continues over the far southeast corner of the plateau of the Islas Georgias del Sur (South Georgia). Her permanence in this zone since March, and her circular trail, indicate that she has found a highly productive feeding area.

  • Eos remains over the plateau of the Islas Georgias del Sur (South Georgia), in the far southeast and close to the slope of the archipelago. Her prolonged stay of many weeks at the northern tip of the Scotia Sea, and her circular tracks, suggest she has found a productive patch in which to feed, and to which Artemisa and Persefone seem to be approaching.

  • Eos has been roaming the shelf off Islas Georgias del Sur (South Georgias shelf) since the end of February. She explored the northern sector, traveling southeast, always near the archipelago shelf’s slope. Her prolonged time in this area and the pattern of her movements suggest that Eos is feeding.

  • After the last update, Eos explored the northern section of the Islas Georgias del Sur (South Georgia) plateau. She has now paused in the northeastern section, over the slope of the archipelago. Eos’ movements indicate she has likely found a productive zone in which to feed.

  • 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.
