Abstract
Un método para procesar datos a partir de un par de hidrofono-geofono co-ubicado de receptores sísmicos en un sistema de cable de fondo oceánico; se obtiene ruido ambiente pare el hidrofono y geofono; se determina una señal de ruido relativa encontrando la diferencia normalizada entre señales de ruido del hidrofono y geofono; después se miden señales de datos del geofono e hidrofono; después se miden señales de datos del geofono e hidrofono por una cantidad igual a la señal de ruido relativa.
