By the turn of the 19th and 20th centuries, exploration of the Antarctic mainland had begun in earnest, with expeditions from Belgium, Britain and Sweden. Germany entered the field with the first German Antarctic Expedition, 1901–03, led by Erich von Drygalski in the ship "Gauss". Drygalski discovered land south of the Kerguelen Islands, but his ship became trapped in the ice at 66°7'S 89°38'E, while still 85 km (46 nautical miles (nmi) from the land. He named this distant coast Kaiser Wilhelm II Land, and an extinct volcano, also observed, was called Gaussberg. Most of the scientific work of the expedition was carried out in a winter station established on the sea ice. When after more than a year "Gauss" was freed, Drygalski tried but was unable to take the ship further south. Hence, when he returned to Germany, in an era when geographical achievements were valued more than scientific results, he found that the expedition was compared unfavourably with Robert Falcon Scott's concurrent "Discovery" Expedition, which had achieved a farthest south mark of 82°17'. Drygalski's scientific results, published over three decades, would retrospectively be recognised as of outstanding importance, but the immediate reaction to his expedition was one of a national failure.
