The California Current, Devils Hole, and Pleistocene climate.
Herbert et al. (1) are to be commended for their convincing and important correlation of midto late-Pleistocene California Current sea surface temperatures (SSTs), California coastal vegetation, and the paleotemperature record in vein calcite at Devils Hole, Nevada. Their intriguing notion linking California Current SSTs and the Laurentide ice sheet, however, is open to question, as is their as...
متن کاملDating of the devils hole calcite vein.
et al. (2) present a long, continuous, highresolution climate record extracted from a calcite vein in Devils Hole, Nevada. If their dating is accurate, the record appears to contradict the Milankovitch hypothesis (3). Dating of subsamples of the vein was done with the use of well-established principles of 230Th dating (4) and with recently developed techniques for precise measurement of 230Th a...
متن کاملPopulation ecology and monitoring of the endangered Devils Hole pupfish
We assessed four potential sources of error in estimating size of the population of Devils Hole pupfish (Cyprinodon diabolis); net, time of day, diver, and order of diver. Experimental dives (3/day) were conducted during 4 days in July 2009. Effects of the four sources of error on estimates from dive surveys were analyzed using a split-split plot ANOVA. Diver and order of diver had no significa...
متن کاملA Miocene to Pleistocene climate and elevation record of the Sierra Nevada (California).
Orographic precipitation of Pacific-sourced moisture creates a rain shadow across the central part of the Sierra Nevada (California) that contrasts with the southern part of the range, where seasonal monsoonal precipitation sourced to the south obscures this rain shadow effect. Orographic rainout systematically lowers the hydrogen isotope composition of precipitation (deltaD(ppt)) and therefore...
متن کاملA correlation between Earth’s inclinations and the times of the cold events recorded in Devils Hole climate data
The calculated values of Earth’s inclinations during the cold events in the 500 kyr climate record of Devils Hole show a correlation: they cluster in the regions around 1 and 2 degrees. The Devils Hole record has been chosen, since it was dated by absolute methods. Other climate records covering the same period also have a reduced number of cold events between the two regions. The correlation l...
