Abstract
Calcite speleothems have become a significant component of research into past environments, especially climate research. A particular strength of speleothems in this regard is their unique ability to be accurately dated over a long period of geological time by either U/Th or U/Pb dating techniques. Stalagmites are also useful as they contain a range of climatic and environmental proxies such as oxygen and carbon isotopes, trace cations and organic compounds. How can such scientific sampling be managed and what restraints need to be placed? Do we want or need the science? Speleologists and cave managers cannot ignore the pressures for samples and need to understand the valid requirements of the science whilst balancing the need for good cave management. If we understand in general terms why particular numbers of samples are required, we will gain the best from the science without seriously damaging caves. This presentation will look at issues relating to cave conservation and makes some suggestions regarding scientific sampling, publication and use of science.
