Comment on 'Major hydrological regime change along the semiarid western coast of South America during the early Holocene' by Ortega et al., Quaternary Research 78(3), pp. 513-527.

摘要

Ortega et al. (2012) recently published a study presenting the hy-drological regime changes along the semiarid coast of Chile (30-32°S) during the early Holocene based on sedimentological, stratigraphical and geomorphological data from Quebrada Santa Julia (QSJ). They suggest a major hydrologic change in the area from arid conditions without heavy rainfall events and local moisture associated to coastal fog to wetter conditions around 8600 cal yr BP, and the onset of modern ENSO influence since 5700 cal yr BP.
