Global GPS Network Equipment Upgrade, Cachoeira Paulista, SP, Brazil The Permanent IGS Station in Cachoeira, Paulista, SP, Brazil, (CHPI) is operated by The National Institute for Space Research (INPE), the Jet Propulsion Laboratory (JPL) / NASA and UNAVCO. A site maintenance visit was carried out in May of 2003, upgrading the GPS equipment to a new Ashtech Z-Reference station receiver and chokering antenna. A meterological package measuring temperature, pressure, and humidity was also installed.

Mississippi Delta One of this projects' goal is to reconstruct the history of sea level in the Mississippi Delta for the last 2000 years through the collection and dating of peat samples. The GPS component of this project is to measure the elevations of the peat sample locations with cm accuracy and to quantify the vertical errors involved. UNAVCO provided four GPS systems, field support, and data processing support.

McCall Glacier McCall Glacier in the northern Brooks Range is used as an index for glacier contributions of fresh water inputs into the Arctic Ocean. The primary efforts are directed towards mass balance and flow dynamics. Bjorn Johns supported the most intensive initial season of the project to establish a local network and re-survey previous mass-balance locations.

Vertical Ground Motion Monitoring, Las Vegas The GPS Station UNR2 is located in Mesquite Nevada, approximately 60 miles North East of Las Vegas. The purpose of the permanent GPS station is to measure the vertical ground motion as water is extracted from the water table below. The GPS equipment is contained in a water pumping station which has been recently installed and is maintained by the Virgin Valley Water District.

Salmon Falls Creek Landslide Monitoring Project, Twin Falls, Idaho A landslide is pinching off the Salmon Falls Creek and as a result a natural dam is forming. The potential instability of the dam is cause for concern as there are several communities located downstream of the landslide. Idaho State University requested UNAVCO support for the deployment of GPS instrumentation in order to monitor the progress of the slowly creeping slide.
