Monday 10th March , 19:30 to 21:00 BCRA Cave Science Seminar: The Underground Mistakes of My Career. Lessons Learned from Maaras Cave, Greece
With: Christos Pennos, Aristotle University of Thessaloniki, School of Geology, Thessaloniki, Greece.
Time: Mon 10-Mar 2025, 19:30 to 21:00 GMT.
To Watch: see Joining via Zoom.
In this talk, I will present data collected from Maaras Cave over the past seven years, focusing primarily on hydrogeology and geomorphology. The Maaras Cave system is located along the northwestern margin of the Aggitis River basin. It contains an active fluvial system fed by a closed karstic basin, the Kato Nevrokopi polje, to the northwest. The cave is formed within the marbles of the Rhodope Massif and exhibits a distinct morphological pattern. It lacks closed loops and follows a hierarchical structure, where lower-order tributaries merge into higher-order passages. The system consists of two main tributaries, an eastern and a western branch—that converge into a single conduit flowing toward the spring a typical branch work cave following Palmer's classification.

2025 BCRA Science Symposium and AGM Please keep the weekend of 11/12 October free so you can attend the 2025 science symposium and AGM. This will be held in the School of Geographical Sciences at Bristol University, hosted by Linda Wilson and Dave Richardson. The BCRA AGM will be held at lunchtime on the 11th of October and there will be several field trips on the 12th.
UIS (Union Internationale de Speleology) Congress Bid for 2029 Update the BCRA in conjunction with the BCA are putting in a bid in to host the 2029 International Congress of Speleology. The UIS hosts an International Congress of Speleology every four years which is the world’s most significant gathering of cave and karst scientists, educators ,managers and explorers. Anyone wishing to assist with the bid should contact the BCRA Chairman and further information will follow if we are successful in our bid to host this prestigious event.
BCRA membership If you have not paid for the coming year, it is not to late to pay through Just Go system
The next council meeting will be held on the 9th of April 2025 via zoom 20.00 to 21.30 Further information is available on the BCRA website
Supporting BCRA.
Members will note that there has been a lack of field meetings since the end of Covid restrictions and we encourage anyone willing to organise a meeting to contact the secretary.
IT Support
Following our appeal in the last Newsletter we now have two volunteers who are doing great work on data from the British Cave Science Centre at Poole’s Cavern. An even bigger task is an overhaul / redesign on the BCRA website . If you feel that you can assist, please contact the secretary: bcra-secretary@bcra.org.uk
Derbyshire Explorers Forum was extremely well attended with some well documented explorations across Derbyshire and much of interest to cave scientists |
