A method for recording seismic data in deep water. A plurality of seismic data recorders are attached to a wire stored on a seismic vessel. A free end of the wire is deployed into the water, and the recorders are attached at selected positions along the wire. The wire and recorders are lowered into the water as the vessel moves to control the recorder deployment. The wire controls recorder location and establishes the recorder spacing interval. After the recorders are operated to record seismic data, the wire and attached recorders can be retrieved to the water surface. The recorders can be detached from the wire to facilitate storage and data retrieval from each recorder.

[ What is claimed is:] [1.] A method for collecting seismic data in water, comprising the steps of:deploying a wire free end into the water;engaging a plurality of recorders with said wire at selected locations along said wire;attaching said recorders to said wire;lowering said wire and engaged recorders into the water until said recorders are positioned at selected positions relative to the seafloor underlying the water, wherein the interval between adjacent recorders is established by the engagement with said wire;operating said recorders to detect seismic source energy reflections and to record seismic data representing such reflections; andraising said wire to retrieve said recorders to the water surface.
