The NSF Centers for Transformative Environmental Monitoring Programs (CTEMPs) will offer a one-day hands-on workshop on the theory, application and analysis of distributed temperature sensing (DTS) for earth sciences. The workshop will accommodate a wide range of practitioners, from those interested in an introduction to the methods, to those wanting to learn state of the art data processing to getting the greatest possible precision from your DTS data. Examples will be taken from deep ice drilling, the Dead Sea, atmospheric turbulence in Colorado, deep rock installations in Nevada, and rivers and lakes around the world. All participants will have the opportunity to work directly with a wide range of DTS instruments, instrument manufacturers and cables designed specifically for environmental sensing. DTS manufacturers, fiber optic cable manufacturers, and CTEMPs staff will lecture and be available for consultation on special issues.
