Previous volumes in this 'Developments in Paleoenvironmental Research' (DPER) series have focussed on providing in-depth descriptions of palaeoenvironmental techniques or have described the applications of these approaches on various regional bases. The former of these now provide an invaluable series of standard text books for scientists and students, while the latter show how the application of palaeo-techniques can be used across broad geographical scales. In this current volume, we have attempted something a little different. Not only are a variety of palaeo-techniques applied to a single, small lake, but we have tried to show how these methods, and the data derived from them, can be integrated synergistically with contemporary monitoring and predictive modelling. The acidification and metals research provide two good examples of this. Along with other upland lakes across the UK, the early research work at Lochnagar was based on assessing the competing hypotheses for the causes of surface water acidification. As a result, palaeolimnological techniques were used to assess the timing and extent of pH changes over hundreds of years. The subsequent establishment of the UK Acid Waters Monitoring Network (UK AWMN) then allowed a range of biological and chemical parameters to be assessed routinely in order to determine the rate at which the lakes and streams, including Lochnagar, were recovering following emissions reductions.

Brings together the knowledge gained over two decades of multi-disciplinary scientific study, with the results of lake sediment research covering millennia, to show how the loch has changed and developed both naturally and as a result of human impact Because of the focus on a single site, at which a great deal of scientific study has been conducted, it allows an in-depth treatment of subjects that is not possible in texts dealing with these subjects more generally Provides more extensive and detailed background information for interested visitors to the area than standard guidebooks which are either short guides to a much wider region or designed specifically for one interest group (i.e. walking and climbing guides) Draws from a broad range of disciplines (geology, botany, zoology, climatology, meteorology, environmental chemistry) and time-frames (i.e. contemporary high resolution meteorological and hydrological data, to geological data, to future predictions of climate impacts)

Neil Rose's first degree was in Chemistry with Geochemistry at University of Leicester (1981 1984). He then joined the British Antarctic Survey and spent 30 months in the Antarctic working on limnology of sub-Antarctic lakes and discovering the joys of lake sediment. Upon return to the UK, he joined the Palaeoecology Research Unit (later becoming the Environmental Change Research Centre - ECRC) at University College London as a Research Assistant. His PhD was awarded in July 1991 entitled "Fly-ash particles in lake sediments: Extraction, characterisation and distribution". Since then he has remained with the ECRC being appointed Principal Research Fellow in October 2001. His main research focus is in the use of lake sediments to determine spatial and temporal distributions of pollutants in remote lakes and this has led him to work in Svalbard, Greenland, Uganda, China, Alaska and many European mountain areas. Further research areas include the source apportionment of fly-ash particles and the use of SCP temporal profiles to provide lake sediment chronologies for the industrial period. His research at Lochnagar began in 1988 and shows no sign of stopping any time soon.
