Heading west from coastal Oregon we are able to make our initial seismic images beneath the seafloor continuously as we go. Where once our data would have been recorded on magnetic tapes only to be analyzed long after the expedition was over, thanks to the wonders of modern signal processing, we can now make images… read more
