Abstract

Saunders KM, Grosjean M, Hodgson DA (2013) A 950 yr temperature reconstruction from Duckhole Lake, southern Tasmania, Australia. The Holocene 23(6) 771–783. DOI: <named-content>10.1177/0959683612470176</named-content>.Page 771: AbstractThe calibration model was based on a negative, not positive, relationship between trough area (R<subscript>570/630</subscript>) and temperature. The corrected model is: R = −0.56, p<subscript>auto</subscript> < 0.05, root mean squared error of prediction (RMSEP) = 0.21°C, five-year filtered data, calibration period 1911–2000.Page 774 ‘Reflectance spectroscopy’The correlations in this paragraph are negative (not positive as stated in the original paper). The paragraph should read as follows:VIS-RS data are summarized in Figure 3. R<subscript>570/630</subscript> and R<subscript>660/670</subscript> fluctuated throughout the core with a slight overall decreasing trend towards the surface. R<subscript>570/630</subscript> was positively correlated to R<subscript>660/670</subscript> (R = 0.5, p < 0.05). R<subscript>650;700</subscript> and RABD<subscript>660;670</subscript> were highly significantly correlated (R = −0.85, p < 0.05). R<subscript>650;700</subscript> was weakly correlated to R<subscript>660/670</subscript> (R = 0.36). R<subscript>650;700</subscript>, RABD<subscript>660;670</subscript> and R<subscript>660/670</subscript> were significantly correlated with water content (R = −0.83, 0.60 and –0.53, respectively, p < 0.05). Once corrected for water content, the negative correlation between R<subscript>650;700</subscript> and R<subscript>660/670</subscript> increased (R = −0.41, p < 0.05), while there was no longer a correlation between RABD<subscript>660;670</subscript> and R<subscript>660/670</subscript>.Page 775 ‘Calibration with meteorological data’The R values referred to should be negative:All VIS-RS-derived proxies (R<subscript>650;700</subscript>, RABD<subscript>660;670</subscript>, R<subscript>660/670</subscript> and R<subscript>570/630</subscript>) were calibrated to monthly and annual temperature (mean, maximum and minimum) and precipitation (total) for the period AD 1911–2000. R<subscript>650;700</subscript> was most highly and significantly correlated to mean annual (January–December) temperature (R = −0.84, p<subscript>auto</subscript> < 0.05, p<subscript>auto</subscript> after detrending < 0.05).The correlation between R<subscript>650;700</subscript> and annual temperature was highly significant after applying a five-year triangular filter (non-detrended: R = −0.85, p<subscript>auto</subscript> < 0.001; Figure 4a) and remained significant when detrended (R = −0.29, p<subscript>auto</subscript> < 0.05; Figure 4b).Consequently, as R<subscript>650;700</subscript> (reflecting chlorophylls and derivatives) correlated best to temperature, it was used to develop an annual temperature calibration model for Duckhole Lake: R = −0.56, p<subscript>auto</subscript> < 0.05, RMSEP = 0.21°C, where both R and p were adjusted for autocorrelation.Page 778 Figure 4The y axes of the lower panels in 4(a) and 4(b) were not correct. The corrected figure is above: <named-content> Comparison of R650;700 and annual mean temperature: (a) non-detrended R650;700 and mean annual temperature; (b) detrended data. All data are five-year triangular filtered. Note: reversed y axes in the lower panels (proxy data) of (a) and (b). </named-content><graphic></graphic> [ABSTRACT FROM AUTHOR]
