Evaluation of contaminant element sources and mobility in contrasting hydrologic environments of Chile: Creation of regional geochemical baselines
This is a 3 year project funded by ANID from November 2018 to October 2021. In this project, I’m the principal researcher.
The sampling areas are shown in the figure below and the preliminary results are found in the video.
Selected sampling areas of Chile (in red rectangles). (a) Image on left: northern and central Chile; (b) Image on right: central and southern Chile. Climatic zones of Chile following the Köppen classification: the dry and wet Andes (Lliboutry, 1999), central (CVZ), southern (SVZ), and austral (AVZ) volcanic zones separated by the Pampean flat-slab and Chile Rise, respectively. In addition hot springs and volcanoes of Chile are shown. BWhn: warm desert with abundant clouds; BWn: desert with abundant clouds; BWk’: cold desert; BWk: normal desert; EFH: polar (altitude effect); BSk’s: cold semi-arid with winter rain; BSks: temperate semi-arid with winter rain; BSn: semi-arid with abundant clouds; Csb: warm temperate with winter rain; Csbn’s: warm temperate with winter rain and atmospheric humidity; Cfsb: warm rainy temperate, mediterranean-type climate; Cfb: warm, rainy temperate without dry season; Csc: cold temperate with winter rain; Cfsc: cold rainy temperate, mediterranean-type climate; Cfc: cold rainy temperate without dry season; ET: tundra; ETH: tundra (altitude effect); ETH(ws): tundra (altitude effect with scarce or nonexistent rain); ETH(w): tundra (altitude effect with summer rain).
