Surface geophone

A land streamer is an array of geophones designed to be towed along the ground. The name originates from marine streamers: arrays of hydrophones towed behind boats for marine seismic surveys. Land geophysicists have long envied the high productivity achieved in marine surveys. Now it appears that highly-productive reflection, refraction, and surface-wave surveys can be achieved on land. Early Land streamers were developed by individuals using a variety of innovative towing mechanisms. Case histories can be found on the Internet by searching for "land streamer", including papers comparing data quality and productivity between towed array and conventional surveys. As a general rule, geophones planted in the ground set the standard for data quality, but land streamers record excellent data in many applications while making the survey economically feasible. A "good" affordable survey often will be a better choice than a "great" survey that can't be done due to its cost. Geostuff has introduced a commercial land-streamer system which we believe will provide better data, be less expensive, more reliable, and easier to use than individually constructed units. To satisfy the needs of individual applications and users, systems are available with just the hardware, or with a wide variety of geophones in single or multi-component. The basic LS-1 system consists of a base plate, tow webbing, top plate and wing. It is designed to be used with your existing geophones and cables to quickly convert them to a low-cost land streamer.
