A method of installing cable through material, for example, concrete, wood, masonry, plastic steel, or the like comprising a drill bit with a distal end having a hollow tip with an attachment mechanism for receiving the cable. The drill bit is drilled through the material, and left in place while the cable is attached to the proximal end of the drill bit. There is no need to remove the drill bit from the aperture or material to attach the cable thereto. After attachment to the drill bit, the cable is inserted through the aperture with the drill bit and removed from the drill bit after it passes through the material so it can be attached to a receiver device.

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. All 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.
