Weathering & Soils Research Group

The hydrologic and nutrient properties of surface soils in the Luquillo Mountains are considered to vary with lithology, vegetation, climate/elevation, and hillslope position. Rates of chemical weathering, landslide frequency, and physical erosion are also known to vary with lithology. Quantifying these relationships and determining their influence on other CZ processes is the primary focus of the Luquillo Critical Zone Observatory.

  •  To address these questions we are conducting coordinated studies that investigate weathering and soil properties by lithology, vegetation, climate/elevation, and hillslope position. Available infrastructure includes shallow and deep observation wells and lysmeters, a network of soil sampling locations, and a soil archive.
