Afrodita´s tracking route

  • For more than a month now Afrodita has remained in a highly productive zone of the mid-continental shelf, at the latitude of Golfo San Matías, 160 kilometers (99 miles) west of the rim of the continental slope.

  • Afrodita continues exploring areas of high biological productivity over the mid-continental shelf southeast of El Rincon oceanographic front. The circular paths she has been traveling since mid-January suggest she is feeding.

  • Afrodita remains over the continental shelf, traveling short distances in irregular patterns, which suggests she is feeding. There is a sea front in this area known as “Frente El Rincón”, an area of high biological productivity.

  • Afrodita crossed the extreme southwestern section of the deep ocean basin and continued her meandering travels over the continental slope. Mother and calf then traveled slowly northwards, Afrodita most likely feeding in the rich, cold waters of the Malvinas (Falklands) current. When they were at 40°S they crossed the continental slope over to the continental shelf, and today are 400 kilometers (249 miles) south of the Bahia Blanca estuary.

  • Afrodita was the first whale tagged in the 2023 season. She and her calf traveled around the northern section of Golfo Nuevo during her first 13 days tracked. She then visited the Área Natural Protegida El Doradillo to the southwest and returned to Puerto Pirámides bay. On November 3 Afrodita began her migration, crossing the continental shelf and the continental slope at the latitude of the Blue Hole. She then continued to the deep ocean basin and the shelf to the east of the Islas Malvinas (Falkland Islands). When she was near the Antilles Arch (46°S, 52°W) she made a 180° turn, and followed her previous route back, this time towards the northwest.
