Laser Specs for Field Hydrology and Biogeochemistry: Lessons Learned and Future Prospects

Virtual Workshop exploring the potential and pitfalls of a revolutionary technology

Organized by CUAHSI (Consortium of Universities for the Advancement of Hydrologic Science, Inc.) and the USGS, the purpose of the symposium is twofold: (1) exchange technical information on robust application of laser spectrometry, both in field deployment and for analyzing field samples in the lab; and (2) highlight research that makes use of this relatively new technology for understanding basic hydrologic processes and as part of multi-tracer projects that allow new insights into hydrologic and geochemical systems. Thus, goals include both practical and theoretical considerations.
