Assessing the maximum limit of SAR-OSL dating using quartz of different grain sizes

quartz was used (inset to Fig. 3a ). The equivalent data for 63–90 μm grains from M#6# are given in the inset to Fig. 3b . The OSL signal used for analyses was the initial 0 to 0.308 s of the decay curve minus a background from the 1.69–2.30 s interval. LM-OSL signals of 4–11 μm and 63–90 μm grains from sample M#6# were also examined (see Fig. S1 ). Fig. 3 Representative SAR dose response curves and decay curves for fine and coarse quartz.

Koonalda Cave, Nullarbor Plain, South Australia – issues in optical and radiometric dating of deep karst caves

providing reliable dating for Koonalda continues to provide a significant challenge for the interpretation of Aboriginal presence in the site. In turn this has prevented a reliable chronology for the sedimentology, physical formation and palaeoenvironment of the cave ( Jennings, 1961 ; Wright, 1971 and Gillespie, 2002 ). 2 Sampling history Gallus dug three archaeological trenches into the main chamber of the northwest passage between 1960 and 1973 ( Gallus, 1968a ; 1971 and 1973 ). Extensions to the third trench were dug by Richard Wright in 1967 in response

A review of radiometric analysis on soil erosion and deposition studies in Africa

degradation worldwide ( IAEA, 2014 ). According to ICOLD (2009) , 27% of land in Africa is degraded, out of which 65% of agricultural land is degraded due to erosion and/or chemical and physical damage. In addition, soil erosion is reported by Collins et al . (2001) as a serious environmental problem in many African countries. The severe soil erosion and degradation largely affect food security in Sub-Saharan Africa ( Dercon et al ., 2012 ). This has been attributed to many developing countries in Africa having experienced expansion of agriculture on to marginal land

Environmental dose rate determination using a passive dosimeter: Techniques and workflow for α-Al2O3:C chips

dosimeter, especially in the field. Taking advantage of these physical properties, our group has used α-Al 2 O 3 :C for developing a comprehensive dosimetric system easily usable in the field (e.g., archaeological sites). We use α-Al 2 O 3 :C chips produced by Landauer Inc . as detectors. Since its development, this material has been extensively studied (e.g., Whitley and McKeever, 2000 ; Akselrod et al ., 1998 ; Erfurt et al ., 2000 ) and it is nowadays also used as detector for personal dosimetry (cf. Yukihara and McKeever, 2011 ). Chips were favoured over

Dendrochronological dating as the basis for developing a landslide hazard map – An example from the Western Carpathians, Poland

) tool was used to make use of the best method of interpolation. RMSE is the most frequently used parameter determining degree of accuracy. It expresses the dispersion of the distribution of the frequency of variances between the original (real) data and the interpolated data. In statistics and probability theory, RMSE is a widely used measure of conformity between a set of estimates and the actual values ( Li, 1988 ). The calculated RMSE values were similar for the methods tested: from 0.49 (Topo to Raster) to 0.57 (Spline). Although the lowest RMSE value was obtained

Assessing the Sensitivity of Riparian Algarrobo Dulce (Prosopis flexuosa DC) Radial Growth to Hydrological Changes

influence of both hydrological variables upon the ring development, we focused on the common time period from preceding year April to current year March, when cambium activity ends ( Giantomasi et al., 2012 ). Correlations were computed with the software DENDROCLIM2002 and tests for significance were determined through the bootstrap method ( Guiot, 1991 ; Biondi and Waikul, 2004 ). Possible differences in radial growth-environmental variability relation as function of tree spatial distribution were analyzed by the means of ANOVA computed on the r/s coefficients ( r

Low to middle Pleistocene paleoclimatic record from the Kraków-Częstochowa Upland (Poland) based on isotopic and calcite fabrics analyses

goal for this work is the improved estimation of studied flowstone chronologies. Oxygen isotopic stratigraphy is tested as an alternative dating method. The second goal is a regional paleoenvironmental interpretation of the obtained records (including δ 18 O and δ 13 C records) and the results of the petrographic observations. 2 Materials Głęboka Cave is located in southern Poland in the Kraków-Częstochowa Upland and is the largest known cave formed of karst from a natural reserve (Mt. Zborów; Fig. 1 ). Its length is 190 m, and the height difference between
