The SCR watershed has experienced significant change over the past decades due to both urban development and increased drought. The dataset contains measurements of POC samples from Santa Clara River water and sedimentary organic carbon (SOC) from river silt and beach sand, including sample collection information, Δ14C and δ13C measurements and associated analytical uncertainties, and sample collection coordinates. This analysis is helping to establish whether the observed change in the aged OC end member is the result of variation in precipitation or due to other alterations in the watershed. If precipitation is the main control of the aged end member, we can estimate how the expected changes in local climate will affect the OC exported by the SCR. Dr. Hauksson, undergrad student Taylor Hart and PI Ellen Druffel analyzed the samples and are writing the papers with these data.
