Abstract: There is described an underwater positioning body, and a method and apparatus using an underwater positioning body. In an embodiment the positioning body is adapted to be coupled to a flexible elongate member. The elongate member is coupled to an underwater tow body. The positioning body may comprise means for changing or maintaining its horizontal position relative to the tow body for imparting a positioning force on the elongate member during towing.

Abstract: A method for use in surveying a subsurface region beneath a body of water by detecting S waves propagating through the subsurface region. The method comprises using a first sensor configuration to detect mixed S and P waves on or in the subsurface region, using a second sensor configuration located on or in relatively close proximity to the subsurface region to detect P waves in the water, and using the P waves detected in the water to compensate the detected mixed S and P waves, and thereby attenuate the effects of P waves in the mixed S and P waves.

Abstract: A method of providing seismic data (such as marine seismic data) is disclosed. A seismic source is actuated at a plurality of source locations (S2, S4). For each source location, a multicomponent seismic measurement is performed at at least one receiver location (S3). A reconstructing method is applied to each multicomponent measurement to obtain additional data corresponding to source locations additional to the source locations at which the source was actuated (S5). The additional data are output and/or used (S6).
