The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy (IAG). IGETS continues the activities of the Global Geodynamics Project (GGP, 1997-2015) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network.
The Transportable Integrated Geodetic Observatory (TIGO) of the Federal Agency for Cartography and Geodesy (BKG) was operated with different local partners (Universidad de Concepción, Universidad del Bío-Bío, Universidad Católica de la Santísima and Instituto Geografico Militar) from 2002 until 2015 at Concepción/Chile. Continuous temporal gravity and atmospheric pressure time series from the SG is made available to the IGETS data base hosted by ISDC (Information System and Data Center) at GFZ.
The TIGO Observatory was located near Concepción, Chile (longitude: 73.03 W, latitude: 36.84 S, height above MSL: 180 m) in a hilly region based on weathered granite close to the estuary of the Rio Bío-Bío. One component of the observatory was RSG-038, the first remote controlled SG. The SG was operated in a separate building containing one room with 3 pillars of concrete (SG, AG and Seismic). The building was thermally stabilized by air-conditioning system.
The first period of operation of the SG was from December 2002 until June 2008. For a complete update of the cooling system the SG was sent back to the manufacturer. It was reinstalled in December 2009 and recorded until April 2015 gravity and barometric pressure variations.
From June 2006 until May 2013, periodic (almost weekly) measurements with the absolute gravimeter (AG) FG5-227 were performed, except for a maintenance period from October 2007 to October 2008.
The devastating Mw 8.8 Maule earthquake of February 27th 2010 affected also the registration. Re-centering of the sphere and repair of the tilt compensation system was necessary. For more than one year the gravity time series was disturbed by countless seismic aftershocks, causing spikes and steps in the registration.
At the station, a meteorological (precipitation, air temperature, humidity, wind speed) and hydrological (soil moisture, since January 2006, ground water since April 2012) monitoring system is installed and operated in close cooperation with GFZ Potsdam.
