Expeditions and Surveys

★ In 1885-1886, Toll took part in an expedition to the New Siberian Islands, organized by the Petersburg Academy of Sciences and led by Alexander Bunge. Eduard Toll explored the Great Lyakhovsky Island, Bunge Land, Faddeyevsky Island, Kotelny Island, as well as the western shores of the New Siberia Island. In 1886 Toll thought that he had seen an unknown land north of Kotelny. He guessed that this was the so-called "Zemlya Sannikova" (Sannikov Land), a land that Jakow Sannikow and Matvei Gedenschtrom claimed to have seen during their 1808-1810 expedition, but whose existence had never been proved. The results of this expedition were appreciated by the Academy as "a true geographical deed".

★ In 1893 Toll led an expedition of the Petersburg Academy of Sciences to the northern parts of Yakutia and explored the region between the lower reaches of the Lena and Khatanga Rivers. Eduard Toll was the first one to map the plateau between the Anabar and Popigai Rivers and a mountain ridge between the Olenek and Anabar Rivers (which he named after Vasily Pronchischev). He also carried out the geological surveys in the basins of the following rivers: Yana, Indigirka, and Kolyma. During one year and two days the expedition covered 25,000 km, of which 4,200 km were up the rivers, carrying out geodesic surveys en route. Owing to the difficulties of the expedition and his hard work, the Russian Academy of Sciences awarded Eduard V. Toll with the Large Silver Medal of N.M.Prozhevalsky.

★ In 1899, Toll took part in a voyage of the icebreaker Yermak under the command of Stepan Makarov to the shores of Spitsbergen.


★ In 1900-1902, Eduard Toll headed an expedition of the Petersburg Academy of Sciences to the New Siberian Islands on schooner ''Zarya'' (Заря). The main aim of the expedition was to find the legendary Sannikov Land. During this voyage and especially during their winterings near the northwestern part of the Taymyr Peninsula and western part of the Kotelny Island, Eduard Toll conducted an extensive hydrographical, geographical, and geological research.
Due to severe ice conditions the expedition was forced to spend two winters in the region of the bleak New Siberian Archipelago. In the end, Eduard Von Toll traveled to Bennet Island by sledge and kayak along with three expedition members.
Ship "Zarya" attempted to reach Bennett Island to evacuate Toll's party but was unable to do so because of severe ice conditions. Apparently, Toll made a decision to go south to the continent but no further traces of the four men have ever been found.
Two search parties were dispatched in the spring 1903. One of them searched the shores of the New Siberian Islands and the other, naval commander Aleksandr Kolchak traveled by whaleboat to Bennet Island. They did not find the lost explorers but they found the diaries and the collections of the Zarya expedition, which shed light on the tragic fate of Baron Eduard Von Toll and his companions.

The name of Eduard Von Toll remained on the geographical maps Fridtjof Nansen published. He named the Bay at the north-west coast of the Taymyr Peninsula in honour of Eduard Von Toll. There is also the Tollievaya River, a cape on the Tsirkul Island in the Minin Skerries, mountains in Novaya Zemlya, the northernmost cape at Stolbovoy Island, the strait and a plateau at Kotelny Island and the central ice cap at Bennett Island.
In certain fields, like paleontology, zoology and botany many specimens of fauna and flora are named after Baron Eduard Von Toll, like for example the foraminiferan named ''Dendrophyra tolli'' (Awerinzew, 1911).
Baron Toll was an expert in Siberian palaeontology. The following statement of Russian Academician V.A.Obruchev is well-known: ''"In all our guides on physical geography you can encounter the name of Eduard V. Toll as the founder of the doctrine of 'fossilized ice formation' – the doctrine which became a classic one".''
