Task: Question Answering
Input (English): Passage: The Norwegian Bratvaag expedition, studying the glaciers and seas of the Svalbard archipelago from the Norwegian sealing vessel Bratvaag of Ålesund, found the remains of the Andrée expedition on 5 August 1930. Kvitøya was usually inaccessible to the sealing or whaling ships of the time, as it is typically surrounded by a wide belt of thick polar ice and often hidden by thick ice fogs. However, summer in 1930 had been particularly warm, and the surrounding sea was practically free of ice. As Kvitøya was known to be a prime hunting ground for walrus and the fogs over the island on that day were comparatively thin, some of the crew of the Bratvaag took this rare opportunity to land on what they called the "inaccessible island".Two of the sealers in search of water, Olav Salen and Karl Tusvick, discovered Andrée's boat near a small stream, frozen under a mound of snow and full of equipment, including a boathook engraved with the words "Andrée's Polar Expedition, 1896". Presented with this hook, the Bratvaag's captain, Peder Eliassen, assigned the crew to search the site together with the expedition members. Among other finds, they uncovered a journal and two skeletons, identified as Andrée's and Strindberg's remains by monograms found on their clothing.The Bratvaag left the island to continue its scheduled hunting and observations, with the intent of coming back later to see if the ice had melted further and uncovered more artifacts. Further discoveries were made by the M/K Isbjørn of Tromsø, a sealing sloop chartered by news reporters to waylay the Bratvaag. Unsuccessful in this, the reporters and the Isbjørn crew made instead for Kvitøya, landing on the island on 5 September in fine weather and finding even less ice than the Bratvaag had. After photographing the area, they searched for and found Frænkel's body, and additional artifacts, including a tin box containing Strindberg's photographic film, his logbook, and maps. The crews of both ships turned over their finds to a scientific commission of the Swedish and Norwegian governments in Tromsø on 2 and 16 September, respectively. The bodies of the three explorers were transported to Stockholm, arriving on 5 October. 
Question: Who  uncovered a journal and two skeletons?
