Natural History of the Phlox Familys or atmospheric pressure changes. Finally long-period gravity variations due to polar motion or hydrogeology can also be observed by superconducting gravimeters because of their low instrumental drift.

Seafloor Geodesy Applied to the Study of Oceanic Spreading Centersystems spanning more than a few kilometers cannot rely solely on this approach. Fortunately, geological evidence suggests that the bulk of spreading center strain accumulation occurs within a few kilometers of the ridge axis. Two approaches to acoustic strain monitoring have emerged. The direct appr

A Method for Measurement of Gravitational Acceleration by Using a Fabry-Perot Interferometererot interferometer had characteristics as theoretically predicted although the sensitivity for the gravitational acceleration is not very high compared with an ideal case owing to beam splitters of medium transmission coefficient. This method is suitable for unmanned automatic measurement of gravit

The seismicity of West and Central Africaen piers were less than 4 microgal. The results show the standard deviation of all instrument’s observations to be 3 microgal while the FG5 instruments (101, 102, 104, 106, 107 and 111) compared at less than 1 microgal (1 microgal = 10. m/ s .).
