The GPS station Enta, (ENTA & ENTC), is operated by the Institute of Earth Sciences, University of Iceland, in collaboration with IMO and with support from RANNIS. Many thanks go to the Icelandic Coastguard for their field assistance. The GPS benchmark ENTA was installed in 1993. Semi continuous measurements at the site, using a simple tripod setup, began on the 26. March 2010 in response to the Eyjafjallajokull flank eruption (20. March). On May 29 a permanent short drilled braced steel monument was set up next to the site (ENTC).
The data were analyzed at the University of Iceland using the GAMIT/GLOBK analysis software using over 100 global reference stations to determine stations coordinates in the ITRF05 reference frame. Here we show detrended time series for the North, East and Up components (in millimeters). The GPS time series are detrended using linear terms estimated from 2001-2009 campaign GPS data. The red thick line show 20. March and 14. April 2010, the red thin lines show 9. July and 6. September 2011. For more information contact Sigrun Hreinsdottir, IES |
