This project of collaborative research (project Ha of the NERC TIGGER programme—Terrestrial Initiative in Global Geological Environmental Research) into the climatic history of the late Holocene used a variety of techniques, both tested and experim

The Anglesey lakes, Wales, UK—A palaeolimnological study of the eutrophication and nature conservation status
Autor: E. Y. Haworth, L. C. V. Pinder, C. A. Duigan, J. P. Lishman
Publikováno v: Aquatic Conservation: Marine and Freshwater Ecosystems. 6:61-80
1. Palaeolimnological techniques were used to investigate recent environmental change in three shallow, coastal lakes (Coron, Dinam and Penrhyn) within biological SSSIs on Anglesey, Wales, U.K., where agriculture has influenced two sites while a thir

An assessment of the sources of error in estimations of bulk sedimentary pigment concentrations and its implications for trophic status assessment
Autor: P. V. Allen, J. Hilton, T. R. Carrick, J. P. Lishman
Publikováno v: Hydrobiologia. 218:247-254
Pigment concentrations in surface sediments in two lakes were analysed on ten occasions over a year. Statistical analysis showed that mean concentrations varied through the year and the relative contribution of several sources of variability (analyti

The dominant processes of sediment distribution and focusing in a small, eutrophic, monomictic lake
Autor: P. V. Allen, J. P. Lishman, J. Hilton
Publikováno v: Limnology and Oceanography. 31:125-133
There is evidence for 10 mechanisms of sediment distribution in small lakes. The sediment accumulation rates measured from a common horizon in cores from 64 sites on Esthwaite Water, U.K., were used to determine the relative importance of these mecha

A comparison of some rapid techniques for the measurement of density in soft sediments
Autor: J. Hilton, J. P. Lishman, A. Millington
Publikováno v: Sedimentology. 33:777-781
Four different methods of measuring density in soft sediments have been compared with the density bottle method. Measurement of the wet sediment volume was found to be the step which limited accuracy. Use of open calibrated rings during the slicing o
