Gun-launched instrumented seabed penetrators: initial field tests of the ISP-1 and ISP-2 systems
Until May 1982, the use of instrumented penetrators to obtain in-situ measurements of marine sediment properties had been limited to maximum depths into the sediment on the order of 10 m. This paper describes the initial field tests of two gun-launched, instrumented, seabed-penetrator systems (ISP-1 and ISP-2). These tests have extended the technology of instrumented seabed penetrators by demonstrating the feasibility of obtaining in-situ measurements from depths into sediment greater than 30 m. While the primary objective of these tests was to demonstrate feasibility, a secondary objective was to obtain useful information about the gas-bearing sediments in a region of the Gulf of Mexico currently being actively investigated by several organizations. This paper describes the ISP-1 and ISP-2 and discusses the results of the data from these tests. Furthermore, several new geotechnical instruments that could be developed to exploit the capabilities demonstrated by these tests are discussed. 15 figures.
