Values are numbers of valves per gram of dry sediment and are presented by depth in core. A chronology for the core is also provided by radiocarbon dates and short-lived radio-isotopes. The data provide a proxy for changing hydroclimate, lake-level and carbon cycling in the lake and its catchment for the period 2000 – 200 CE Prof Jonathan Holmes University College London Department of Geography Pearson Building, Gower Street London WC1E 6BT United Kingdom not available originator Enquiries British Geological Survey United Kingdom not available distributor Enquiries British Geological Survey United Kingdom not available pointOfContact notApplicable https://resources.bgs.ac.uk/images/geonetworkThumbs/0b5eea83-19d7-5017-e063-0937940ad151.png Geology GEMET - INSPIRE themes, version 1.0 2008-06-01 publication Ostracoda Palaeoclimatology BGS Thesaurus of Geosciences 2022 revision NGDC Deposited Data dataCentre NERC_DDC otherRestrictions licenceOGL Available under the Open Government Licence subject to the following acknowledgement accompanying the reproduced NERC materials "Contains NERC materials ©NERC [year]" otherRestrictions The copyright of materials derived from the British Geological Survey's work is vested in the Natural Environment Research Council [NERC].

The > 250 µm residues were oven dried at 40 ?C and ostracod shells picked from the dried, coarse fractions under a low-power binocular microscope. Although similar amounts of sediment were processed for each level, exact weights were not recorded. Separate samples were therefore subsequently weighed, processed in the same way as the original sample and the ostracod content counted to estimate ostracod concentrations in valves per gram of dry sediment. These data were then used to estimate the concentration of each species, in valves per gram of dry sediment, which are the values presented here.
