Luquillo Critical Zone Observatory: linking spatial and temporal patterns in stream chemistry to underlying critical zone architecture

The Luquillo Critical Zone Observatory is located in the Luquillo Mountains of northeastern Puerto Rico. The mountain massif drains rapidly to the ocean, and consists of three primary bedrock types: volcaniclastic, granitic, and hornfels. For streams draining the three bedrock types, I will describe the time course of stream chemistry (up to 33 years of data, including major storms and hurricanes); spatial variation in phosphorus; and linkages between longitudinal changes in stream chemistry and bedrock lithology.
