img3A land streamer is an array of geophones designed to be towed along the ground. The name orginates from marine streamers, which are a string of hydrophones towed behind ships. Land geophysicist have long envied the high productivity achieved in marine surveys. Now it appears that highly-productive relection, refraction and surface-wave survyes can be achieved on land. As a general rule, geophones planted in the ground set the standard for data quality, but land steamer surveys are excellent in many applications, while making the survey economically feasibile. References can be found on the Geostuff website including papers comparing data quality and productivity between towed aray and conventaional surveys.
