Task: Question Answering
Input (English): Passage: Before the start of the voyage Nansen decided to deviate from his original plan: instead of following Jeannette's route to the New Siberian Islands by way of the Bering Strait, he would make a shorter journey, taking Nordenskiöld's North-East Passage along the northern coast of Siberia. Fram left Christiania on 24 June 1893, seen on her way by a cannon salute from the fort and the cheers of thousands of well-wishers. This was the first of a series of farewells as Fram sailed round the coast and moved northward, reaching Bergen on 1 July (where there was a great banquet in Nansen's honour), Trondheim on 5 July and Tromsø, north of the Arctic Circle, a week later.  The last Norwegian port of call was Vardø, where Fram arrived on 18 July.  After the final provisions were taken on board, Nansen, Sverdrup, Hansen and Blessing spent their last hours ashore in a sauna, being beaten with birch twigs by two young girls.The first leg of the journey eastward took Fram across the Barents Sea towards Novaya Zemlya and then to the North Russian settlement of Khabarova where the first batch of dogs was brought on board.  On 3 August Fram weighed anchor and moved cautiously eastward, entering the Kara Sea the next day. Few ships had sailed the Kara Sea before, and charts were incomplete. On 18 August, in the area of the Yenisei River delta, an uncharted island was discovered and named Sverdrup Island after Fram's commander. Fram was now moving towards the Taimyr Peninsula and Cape Chelyuskin, the most northerly point of the Eurasian continental mass. Heavy ice slowed the expedition's progress, and at the end of August it was held up for four days while the ship's boiler was repaired and cleaned. The crew also experienced the dead water phenomenon, where a ship's forward progress is impeded by energy dissipation caused by a layer of fresh water lying on top of heavier salt water. On 9 September a wide stretch of ice-free water opened up, and next day Fram rounded Cape Chelyuskin—the second ship to do so, after Nordenskiöld's Vega in 1878—and entered the Laptev Sea.After being prevented by ice from reaching the mouth of the Olenyok River, where a second batch of dogs was waiting to be picked up, Fram moved north and east towards the New Siberian Islands. Nansen's hope was to find open water to 80° north latitude and then enter the pack; however, on 20 September ice was sighted just south of 78°.  Fram followed the line of the ice before stopping in a small bay beyond the 78° mark. On 28 September it became evident that the ice would not break up, and the dogs were moved from the ship to kennels on the ice. On 5 October the rudder was raised to a position of safety and the ship, in Scott Hansen's words, was "well and truly moored for the winter". The position was 78°49′N, 132°53′E. 
Question: What did the voyage heading to the New Siberian Islands decide to name the first uncharted island they discovered in August?
Output (English): Sverdrup Island.
