When we use streamers or ocean-bottom cables, we have the data in real time. When we use autonomous ocean-bottom nodes, we have the data only when we retrieve them. With 100 days endurance, we may be shooting blind for three months without knowing if

We analyse seismic polarisation of direct and reflected PS arrivals on multi-component ocean bottom (OB) data, by mapping vector fidelity as a function of azimuth and angle of incidence at the seabed. We compare data from a cable system with data fro

We present a detailed mode identification performed on the 1994 Whole Earth Telescope (WET) run on GD 358. The results are compared with that obtained for the same star from the 1990 WET data. The two temporal spectra show very few qualitative differ

When we use cables, we have the data in real time. When we use autonomous nodes we have the data only when we retrieve them. This is a challenging situation. The main objective of onboard QC is to verify that a survey can proceed as planned, or not!

We compute the energy density and pressures due to the quantum production of particles of a scalar field. This scalar field propagates in the external gravitational field of a (3+1)-dimensional, spherically symmetric, static geometry with flat spatia

The quantum production of spinless particles 〈 n k ( t )〉, and of energy-momentum-stress 〈 T â b ( P )〉 by the tidal forces of classical curved space-time are computed for the test case of 1 + 1 dimensions. Our new tools are gauge invariant

We consider the quantization of a tachyon field T in the background of the two-dimensional black hole as described by the SL (2, R ) / U (1) coset theory recently proposed by Witten. An explicit expression for 〈T2(x)〉 in the Hartle-Hawking state

We present a method that can be used to determine geophone orientation in a typical multi-component cable system, using data from a single seismic shot. Orientation angles estimated this way can serve as real-time QC during acquisition when not all d
