Source-derived summary

Yuriy Mykhailovych Kasyan (Ukrainian: Юрій Михайлович Касьян; born 6 May 1961) is a Ukrainian speleologist, most known for his work in cave exploration, especially as the Call of the Abyss research project coordinator. He was heading the speleological expeditions to caves of the Arabika massif in Abkhazia and, with Aleksandr Klimčuk, to Aladaglar massif in Turkey. Some of the world's deepest caves were explored, including the first cave, deeper than 2,000 m, the Krubera-Voronja Cave.

Early life, education and career

Kasyan was born in Sniatyn, a small town in Western Ukraine, in the Ivano-Frankivsk Oblast, to the north of Moldova. His father, Mykhailo Yuriyovych Kasyan, was chairman of the District Council of the Sports Society "Grain Ear", which promoted athletic development in the countryside, and his mother was a statistician in the accounting department of the district party committee. After high school in Sniatyn where he also pursued swimming and freestyle wrestling he graduated (1984) in geology at the Ivano-Frankivsk National Technical University of Oil and Gas in the province capital Ivano-Frankivsk. After graduation, he moved to Poltava for a job in the regional branch of the All-Union Research and Design Institute for Explosive Geophysical Survey Methods. Kasyan continued as instructor at the Poltava regional center of education in tourism and local history and from there moved on to a career in industrial rope access.

Speleology

In the autumn of 1978, at the beginning of geology study in Ivano-Frankivsk, there were 3 available extra-curricular courses: in tourism, rock climbing and speleology. From the latter two Kasyan chose speleology as the closest to geology and joined the Ivano-Frankivsk speleo club Протей [Proteus].

Editorial summary

The public source identifies “Yuriy Kasyan” as ukrainian speleologist (born 1961). This brief keeps that definition visible, then builds a research path around Yuriy, Kasyan and Ukrainian.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1961, 1984, 1978—that can be checked directly. The linked authority record independently contributes the date 1961-05-06. Its value is orientation rather than verdict, with Yuriy, Kasyan and Ukrainian providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Yuriy Kasyan”, the useful work is to connect “ukrainian speleologist (born 1961)” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q66364611. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1961, 1984 and 1978.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
