    Notes: [Auszug] Surface water acidification has been variously ascribed to the effects of acid precipitation3, land-use change4, afforestation5'6 and long-term change7, the importance of which can be assessed by palaeoecological techniques. We consider the last two of these processes first. Long-term ...

    Notes: [Auszug] Many lakes in Europe and North America have been acidified in recent decades3'8; however, arguments persist over the possible causes of acidification. Rosenquist1, supported by Krug and Frink2, has argued that the increase in the quantity of raw humus in lake catchments as a result of land-use ...

    Diatoms, lake acidification and the Surface Water Acidification Programme (SWAP): a review (1994)
    Springer
    Hydrobiologia 274 (1994), S. 1-7 
    Details
    ISSN: 1573-5117
    Keywords: lake acidification ; diatoms ; palaeolimnology ; weighted averaging ; database ; quality control

    Topics: Biology
    Notes: Abstract The Surface Water Acidification Programme (SWAP) was set up as collaborative research project involving scientists from Norway, Sweden and the UK. Its aim was to evaluate the factors responsible for fish decline in acid streams and lakes. A substantial sub-project was concerned with the palaeolimnological evidence for acidification and its causes. The central technique used was diatom analysis. In order to harmonise methodology between the seven diatomists from four laboratories in three countries a programme of taxonomic quality control was organised, involving slide exchanges, ‘blind’ counting, and regular workshops. In addition a calibration data-set of surface sediment diatoms and water chemistry from 170 lakes was constructed and archived on DISCO, the UCL diatom database. This data-set was used to generate diatom-chemistry transfer functions for pH, DOC and total Al using a weighted averaging technique. Application of the pH transfer function to sediment cores from a range of lakes demonstrated a dose-response relationship between lake sensitivity to acidification (as represented by mean Ca2+ values) and acid deposition (g S m -2 yr -1), indicating the overwhelming importance of acid deposition as the cause of lake acidification.

    An automated technique for the accurate positioning of sediment core sites and the bathymetric mapping of lake basins (1983)
    Springer
    Hydrobiologia 103 (1983), S. 71-74 
    Details
    ISSN: 1573-5117
    Keywords: paleolimnology ; sediment core positioning ; hydrographic survey ; computer contouring ; morphometric calculation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Automated techniques for sediment core site positioning, hydrographic survey, and contour mapping are described. The computer contouring system can be extended to calculate values for morphometric variables such as maximum length (1max), maximum width (wmax), lake perimeter (10), lake area (A) and lake volume (V). The techniques are exemplified using results from Augher Lough, Northern Ireland.

    Obervations on the occurrence of scales and bristles of mallomonas spp. (Chrysophyceae) in the micro-laminated sediments of a small lake in finnish North Karelia (1980)
    Springer
    Hydrobiologia 71 (1980), S. 225-232 
    Details
    ISSN: 1573-5117
    Keywords: Mallomonas scales and bristles ; laminated sediments
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Scales and bristles ofMallomonas crassisquama (Asmund) Fott andM. elongata Reverdin are reported from the laminated sediments of Laukunlampi, a small kettlehole lake in N. Karelia, Finland. The white summer laminae in the deeper sediment are composed almost entirely ofM. crassisquama scales and bristles. The taxonomy, ecology and distribution ofM. crassisquama andM. elongata are briefly discussed and factors influencing the preservation of scales and bristles in sediments are considered. It is suggested that analysis of sedimentary associations of scales, bristles and cysts could be used to improve cyst taxonomy inMallomonas.

    ISSN: 1573-5117
    Keywords: sediment ; diatoms ; phosphorus ; acidification ; eutrophication

    Topics: Biology
    Notes: Abstract Palaeolimnology has developed rapidly over the last two decades to deal with problems of eutrophication, and acidification. This paper reveiew the techniques for coring, dating and interpreting sediments. The applications of palaeolimnology in interpreting the past through ‘transfer functions’ calculated from biological indices are reviewed. Rates of change, the causes of change, and the restoration of lakes to some predefined target are reviewed and the direction of future developments considered.

    Sensitive surface waters — A UK perspective (1986)
    Springer
    Water, air & soil pollution 31 (1986), S. 631-645 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract This overview of sensitive surface waters in the United Kingdom has focused on palaeolimnological studies, the estimation of acidification values according the Henriksen, and correlation with non-marine sulphate values of available chemical data and trends in salmonid populations. The palaeolimnological studies of lakes with unafforested catchments in Galloway led to the conclusion that changes in water acidity, since the 1800's, have been caused by acid deposition. Significant differences in stream chemistry between mature conifer forests and adjacent moorland catchments, in both Wales and Scotland, suggest that afforestation as well as acid deposition have contributed to the decline and, in some areas, the elimination of the salmonid population.
