OHIG Site Information Form International GPS Service for Geodynamics 0. Form Prepared by (full name) : Dr. Wolfgang Schlueter : Klaus Roettcher : Andreas Reinhold : Reiner Wojdziak : Rudi Stoeger Date Prepared : 09-APR-1997 Report Type : UPDATE Prepared Using : 1. Site Identification of the GPS Monument Site Name : ERS/VLBI Station O'Higgins / Antarctica Four Character ID : OHIG Monument Inscription : Pillar K5 IERS DOMES Number : 66008M001 CDP Number : Date Installed : 14-FEB-1995 00:00 UT Geologic Characteristic : BEDROCK Bedrock Type : METAMORPHIC Bedrock Condition : WEATHERED Fracture Spacing : 50-200 cm Notes : Predominant rocks at the station O'Higgins : are quartz-bearing black, grey and reddish : brown low-metamorphic clay slates and : phylitte slates of the Trinity Peninsula : Formation. They are very brittle, fine- : laminated in the mm- and cm-range and : incline with about 60 to 80 degrees to NW. : Because of these characteristics and the : high clay mineral content and the expansive : force resulting from this the slates are : highly susceptible to weathering and mostly : covered by detrital layers. Only tectonicly : less stressed parts and parts resistant to : weathering stick out from these detrital : masses. These have a linear geometry and : show strong cleavings. The instrusions : of 0.5m to 1.5m thick vein rocks, which : pass through the slates, are significantly : younger. The pillar with the Turbo Rogue : antenna is bolted into one of these veins, : which are very resistant to weathering. Additional Information : A ROGUE SNR-8000 operates since : 14-FEB-1995 at the ERS/VLBI- Station O'Higgins. : Upgrading Firmware firmware from V 3.0 to : V 3.2 04-FEB-1996 16:40 UT. : Malfunctiong ROGUE SNR-8000 S/N T319 have : been replaced by ROGUE SNR-8000 S/N T398 : 17-FEB-1997 00:23 UT (Firmware V 3.2 to : V 3.32.4). 2. Site Location Information City or Town : O'Higgins State or Province : Country : Antarctic Peninsula Tectonic Plate : Antarctican Approximate Position X coordinate (m) : 1525872.392 Y coordinate (m) : -2432481.273 Z coordinate (m) : -5676146.066 Latitude (deg) : 63.320724011 S Longitude (deg) : 57.900342018 W Elevation (m) : 30.621 Additional information : The GPS-System was installed nearby : the German ERS/VLBI-Station and the : Chilenian Base O'Higgins. : The System is a stand-alone-system : during long Antartican-Winter. : Only for VLBI-Observation-Sessions : operators travel to O'Higgins during : short Antarctican-"Summer". 3.
