Calliope´s tracking route

  • Since the beginning of February Calliope has been over the continental shelf, at the latitude of Rawson, 300 kilometers (186 miles) southeast of Peninsula Valdés. Her zigzag path in this area suggests that she is feeding.

  • Calliope returned to the continental shelf during the last week of January, after traveling within the deep ocean basin for almost 3 months. She is now 250 kilometers (155 miles) east of Peninsula Valdés.

  • Calliope is at present about 200 kilometers (124 miles) away from Artemisa. Both of their tracking data show feeding behavior in the ocean basin. This area, as well as the Argentinan continental shelf, are preferred in the summer months by the whales which breed in the waters of Peninsula Valdes.

  • Calliope, as well as Artemisa, is now in the deep ocean basin. While traveling in these deep waters this whale swam in large clockwise circles, which could indicate that she is utilizing the productive currents which bring nutrients to the surface. Mother and calf are now more than 1,300 kilometers (808 miles) east of Peninsula Valdés.

  • Calliope was tagged on October 24, during a brief spell of good weather. This female and her calf explored Golfo Nuevo almost entirely. Like Artemisa, Calliope then traveled to the northeast of the gulf near Punta Cormoranes and Morro Nuevo. On November 7 mother and calf left the waters of Valdés and crossed the continental shelf without stopping until they reached the continental slope. They then traveled from north to south in the Blue Hole, continuing on to the deep ocean basin where Calliope is probably feeding.
