Abstract
The Global Geodynamics Project was renewed for the foreseeable future at the IUGG in Perugia. The second cycle (called GGP2) of operations started in 2003, and followed the initial years of GGP1 (1997–2003). Thus GGP has now completed 10 years of collecting data from all the currently operating superconducting gravimeters (SGs). During the last cycle, GGP operations have gone smoothly for most stations, but with the inevitable instrumental problems. We have lost (at least temporarily) stations Boulder and Bandung, but gained an instrument in MunGyung (S. Korea) and two instruments in Hsinchu (Taiwan). New installations were recently done in Pecny (Czech Republic) and Dehradun (India), and several other locations in the US and Asia are being contemplated in the next cycle of GGP (2007–2011). Over the past two years, we have worked to prepare raw GGP data (at sampling times of 1–5 s) for inclusion into the IRIS data set for the seismologists to use in normal mode studies of the Earth. A successful GGP Workshop was held in Jena, Germany in March 2006, and the first official Asian SG Workshop took place in March 2007 in Taiwan, hosted by our colleagues in Hsinchu. Of continuing interest within GGP is the issue of combining measurements from absolute gravimeters at the SG stations for a variety of long-term studies of the gravity field such as tectonic uplift, subduction zone slip, and determination of the Earth’s centre of mass with respect to the terrestrial reference field. GGP has now become involved with the development of GGOS, a project that intends to coordinate the use of many different geodetic data sets for future ease of access
