Abstract
A marine survey system and method for ultrahigh resolution (UHR) mapping of a marine bottom (B) below a body of water (W) by means of a frame (20) towed as a whole by one or more towing cables (12) at a distance (Xf) behind a marine vessel (10) moving over the water (W) in a movement direction (V). The frame (20) comprises a rigid framework (23) and a plurality of independent acoustic sources (21), wherein each acoustic source (21) is independently controlled to emit a separate acoustic wave (A) propagating through the water (W) and reflecting off bottom regions of the marine bottom (B) for the mapping thereof. The acoustic sources (21) are kept fixated by the rigid framework (23) at a source-to-source distance (Ys) less than four meters in a transverse direction (Y) perpendicular to the movement direction (V) of the vessel (10) to distinguish the bottom regions with an ultrahigh resolution (Ry) of less than two meters at least in the transverse direction (Y).
