Abstract

Se proporcionan sistemas y métodos para detectar parámetros de levantamiento sísmico marino. Un sistema de procesamiento de datos puede obtener datos sísmicos a partir de unidades de adquisición de datos sísmicos dispuestas en un lecho marino en respuesta a una señal acústica propagada desde una fuente acústica a través de una columna de agua. El sistema de procesamiento de datos puede determinar a partir de los datos sísmicos, un tiempo de llegada directo para la señal acústica en cada una de la pluralidad de unidades de adquisición de datos sísmicos, y puede obtener un valor de profundidad estimado de cada una de la pluralidad de unidades de adquisición de datos sísmicos y una velocidad estimada de tránsito de la columna de agua de la señal acústica. El sistema de procesamiento de datos puede aplicar un modelo de profundidad y un modelo de velocidad de tránsito de columna de agua al valor de profundidad estimado y a la velocidad estimada de tránsito de la columna de agua para determinar un valor de profundidad actualizado y una velocidad actualizada de tránsito de columna de agua para cada una de la pluralidad de unidades de adquisición de datos sísmicos.
