Estimating mixing rates from seismic images of oceanic structure
[1] An improved understanding of the spatial distribution of diapycnal mixing in the oceans is the key to elucidating how meridional overturning circulation is closed. The challenge is to develop techniques which can be used to determine the variation of diapycnal mixing as a function of space and time throughout the oceanic volume. One promising approach exploits seismic reflection imaging of ...
متن کاملExtracting Seismic Profiles from Background Seismic Signals
The idea of obtaining the seismic trace representing the impulse response at one receiver due to a source at another receiver has discussed by many authors. Jon Claerbout (see e.g. Rickett and Claerbout, 1996; Claerbout, web) introduced the concept to seismology. It has been investigated in the laboratory by Lobkis and Weaver (2001), observed in seismic data by Campillio and Paul (2003), and in...

15 صفحه اولcrustal conductivity structure of a continental margin, from magnetotelluric investigations
the deep internal structure of the crust can be determined using appropriate seismic and electromagnetic methods. the natural source magnetotelluric (mt) method is the most suitable electromagnetic technique for probing into the deep crust. a long period magnetotelluric data set obtained in the southern chilean andes is investigated in this paper. dimensionality analysis shows that the data may...
متن کاملSegment-scale variations in the crustal structure of 150–300 kyr old fast spreading oceanic crust (East Pacific Rise, 8◦15′N–10◦5′N) from wide-angle seismic refraction profiles
S U M M A R Y We have simultaneously inverted seismic refraction and wide-angle Moho reflection traveltimes for the 2-D crustal thickness and velocity structure of 150–300 kyr old crust along the East Pacific Rise (EPR) between the Siqueiros and Clipperton fracture zones (FZs). Our results show a strong correlation between ridge segmentation and upperand mid-crustal seismic velocities, with hig...
