GPS Monitoring of Vertical Land Movements in the UK

Abstract:	Changes in mean sea level recorded by tide gauges are corrupted by vertical land movements at the tide gauge sites, which can be of a similar order of magnitude. The development of techniques for the application of the Global Positioning System (GPS) to monitoring vertical land movements at tide gauge sites has been on-going at the IESSG since the late 1980s. The IESSG and the Proudman Oceanographic Laboratory (POL) have carried out several projects for monitoring vertical land move-ments at selected sites of the UK National Tide Gauge Network. The initial projects were based on the use of episodic GPS campaigns, and the current project uses a combination of a small number of continuously operating GPS receivers and episodic GPS measurements. The paper gives details of the development and applica-tion of high precision GPS techniques to the monitoring of vertical land movement at tide gauges sites in the UK.
