Welcome to the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics Gravity Lab |
IGPP Gravity GroupOur group began in the mid 1980's when Mark Zumberge and Glenn Sasagawa began surveying California with an absolute gravity meter built at the Institute of Geophysics and Planetary Physics at Scripps Institution of Oceanography. As an outgrowth of that original work, we have continued to apply high precision metrology - often based upon laser interferometry - to problems in geophysics. Today our research projects have evolved beyond gravity research, although that remains an important component of our group's thrust. In addition to gravity measurements on the sea surface, in the mid-water column, on the seafloor, and on land, we are carrying out research on a new optical fiber infrasound sensor (OFIS), optical fiber strain measurements in boreholes and in the Antarctic ice sheet, and we are beginning the design of several new instruments including an observatory seismometer and an AUV-borne gravity meter.
