South African technical diver Karen van den Oever has claimed a new women’s diving depth record, following her 236m descent into Boesmansgat Cave in Northern Cape province.
The 26 March dive lasted 7 hours 18 minutes, most of that time spent decompressing, and was carried out on open circuit scuba using a bottom mix of trimix 6/85.
The record is an unofficial one until verified by Guinness World Records, which had observer Theo van Eeden at the site to witness the dive.
It has been held for nearly 17 years by fellow South African Verna van Schaik, who carried out her own 221m dive at Boesmansgat and welcomed van den Oever’s dive with the words: “Congrats! It is an epic feat!”
Boesmansgat, the world’s third deepest known sinkhole, lies 1.55km above sea-level.
van den Oever’s previous deepest dive at the site was to 201m in February last year. A science graduate from the University of Witwatersrand in her home town of Johannesburg, she is an instructor with technical diving school Somewhere Out There Diving (SWOT), members of which supported her record bid.
