Abstract: A marine seismic survey is performed in icy waters by initially planning a survey track traversing a survey area. The initial track is planned based on initial ice conditions in the survey area having the icy waters. After preparing the system, a seismic system is deployed into the water from a survey vessel at the survey area. This is typically done in an area relatively free of ice. At least one escort vessel escorts the survey vessel as it traverses the survey track and obtains seismic data. The survey vessel tows the seismic system under the surface of the icy water to avoid the ice. AH the while, systems and operators monitor the survey area along the survey track for actual ice conditions. In this way, the escort vessel can handling the actual ice conditions along the survey track so the survey vessel does not need to halt.

Title: System and method for performing seismic surveys with a controlled source using maximum-power sweeps
Inventor: DELLINGER JOSEPH ANTHONY
IPC: G01V1/04
Filed: 2014-09-16
Abstract: The output spectrum of a controllable swept- frequency acoustic source at a given frequency can be controlled by making the rate of change of frequency equal to the desired output power spectrum divided by the squared envelope amplitude of the source output signal, both measured at the time after the start of its frequency sweep at which the sweep frequency passes through the given frequency. The system and method can also be used to correct for propagation effects outside the source by dividing the desired spectrum by the propagation effect. The method can further be used either to obtain an output spectrum of a desired shape from a source operating at maximum output or to design a sweep of a minimum feasible duration that will result in an output spectrum of a specified shape and with a specified amplitude.
