The BGS website and hosted sites such as OneGeology will be temporarily offline for essential maintenance from 12:00 on Monday 27 February. Hopefully normal services will resume within the hour. Apologies for any inconvenience.
The Bedhampton and Havant spring complex in Hampshire is one of the best examples of Chalk karst springs in the UK. This an overview of the karst hydrogeology in the catchment of the springs, based on available data for the catchment, and current knowledge of the nature of Chalk karst in England.
The Eli Simpson Archive is an extensive collection of material covering caves and caving in Yorkshire and Derbyshire. It was compiled by Eli Simpson (1884–1962), the founder of the British Speleological Association (now the British Cave Research Association (BCRA)), with contributions from other members.
We are now about two weeks into the RRS James Cook cruise, which departed from Santa Cruz, Tenerife, on 29 October 2016. The current cruise forms part of the MarineE-tech project (marine ferromanganese deposits — a major resource of e-tech elements).
Karst results from the dissolution of rocks and is usually associated with cave systems and landscapes characterised by rocks sculpted by dissolution, large surface depressions, disappearing rivers and major springs. However, karst processes occur in all soluble rocks, and can result in rapid transport of pollutants into and through the ground, sometimes over distances of many kilometres.
This knowledge exchange project concerns the Chalk and Jurassic and Permian limestones of England. These are soluble-carbonate aquifers in which caves are uncommon and karst often not well-recognised.
