Two Antarctic minke whales marked with "Discovery tags" – 26 cm (10 in) stainless steel tubes with an inscription and number engraved on them – in the [[Southern Ocean]] during the austral summer (January) were recovered a few years later off northeastern Brazil (6° – 7°S, 34°W) during the austral winter (July and September, respectively). The first was marked off Queen Maud Land (69°S 19°E) and the second southeast of the South Orkney Islands (62°S 35°W). Over twenty individuals marked with these Discovery tags showed large-scale movements around the Antarctic continent, each moving more than 30 degrees of longitude – two, in fact, had moved over 100 degrees of longitude. The first was marked off the Adélie Coast (66°S 141°E) and recovered the following season off the Princess Ragnhild Coast (68°S 26°E), a minimum of 114 degrees of longitude. The second was marked north of Cape Adare (68°S 172°E) and recovered nearly six years later northwest of the Riiser-Larsen Peninsula (68°S 32°E), a minimum of over 139 degrees of longitude. Both were marked and recovered in January.
