Some of the world's deepest caves were explored,[2][3] including the first cave, deeper than 2,000 m, the Krubera-Voronja Cave.[4][5]

Early life, education and career

Kasjan was born in Snjatin, a small town in Western Ukraine, in the Ivano-Frankivsk Oblast (Province), to the north of Moldova. His father Mihail Jurjevič Kasjan was chairman of the District Council of the Sports Society "Grain Ear", which promoted athletic development in the countryside, and his mother Nelja Dmitrievna was a statistician in the accounting department of the district party committee. After high school in Snjatin 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.[6] Kasjan continued as instructor at the Poltava regional center of education in tourism and local history[7] and from there moved on to a career in industrial rope access.[8]

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 Kasjan chose speleology as the closest to geology and joined the Ivano-Frankivsk speleo club Протей [Proteus].[9] He stayed till 1984, since 1981 he was its chairman.[10][11] In 1984 he founded the Poltava speleoclub "Poltava-speleo", which he led until 2003.[12] In 2004 he joined the Kiev speleoclub; for several years he was the head of its speleo school, he is a longtime member of the club board.[13]

In 1992 Kasjan was one of the founding members of the Ukrainian Speleological Association (UkrSA).[14][15] As of April 2019 he is the vice-president of the UkrSA; he served as president in the years 1998 - 2001 and 2006 - 2007.[15] Since 2003 he is an honorary member of the UkrSA,[14] in 1996 and 2012 Kasjan was the recipient of the UkrSa Diploma for Outstanding Achievements.[16]

He is the coordinator of the Training and Methodological Commission of the UkrSA, MIPKAR and “Call of the Abyss” projects, head of the UkrSA Cave Rescue Team.[14]

From 1978 to 1998 Kasjan's caving activity was mostly devoted to caves of Western Ukraine and the Crimea, such as Gvozdetsky abyss, Liu-Khosar shaft, Shaft of the lost ones and discovery and mapping of over 1,5 km long Poltavskiy branch of the labyrinthine Mlinki cave.[12][17] He initiated a program of marking and revising the caves of the Karabi plateau in the Crimea (1998).[12]

From 1998 Kasjan participated in several international caving expeditions, to Arabika massif in Abkhazia (as a leader since 1999), to Skalarjevo brezno cave on Mt. Kanin in Slovenia[18] and Aladaglar mountain range in Turkey as the leader of operations in the cave.

Cavers are known for their superstition,[19] and Kasjan was never tempted to estimate expedition potential in advance:

Openly talking about cave depth (you are going to achieve) is a very bad sign. If you think that you will break the record and take too much equipment with you, the cave will get scared and she will stop you.[19]

Arabika Caves

Kasjan's most important achievements are connected to exploration of a cave system above the eastern coast of the Black Sea, in the Ortobalagan valley in Abkhazia.[20][21] He was leading the following expeditions, nearly always organized by the Ukrainian Speleological Association:
