摘要
A data acquisition system for gathering geophysical data, a corresponding method, and a data acquisition unit for use with the system and method are disclosed. The system ( 10 ) comprises a plurality of data acquisition units ( 14 ) for gathering geophysical data, each data acquisition unit ( 14 ) being connectable to at least one sensor ( 15 ) and being arranged, during use, to gather geophysical data from the at least one sensor ( 15 ). Each data acquisition unit ( 14 ) comprises time referencing means ( 48 ) arranged to generate time reference data usable to control the time at which samples of geophysical data are taken. The system ( 10 ) further comprises means for calculating spatial derivatives between samples associated with adjacent sensors ( 15 ) connected during use to the data acquisition units ( 14 ).
