Disclosed are methods and systems for controlling depth profiles of marine geophysical sensor streamers as they are towed in a body of water. An embodiment discloses a method for marine geophysical surveying, the method comprising: towing a geophysical sensor streamer in a body of water having a surface and a floor, the geophysical sensor streamer being coupled to a survey vessel by a lead-in cable, the lead-in cable having a length that extends from the survey vessel; adjusting the length of the lead-in cable to cause a forward end of the geophysical sensor streamer to follow a depth profile; and deflecting the geophysical sensor streamer in the vertical plane at one or more spaced apart locations.
