Data from: Measuring Seafloor Strain with an Optical Fiber Interferometer
About this CollectionA 95.5 day long record of earth strain collected on the seafloor offshore Oregon was collected. The instrument used was a 200-m-long optical fiber cable, stretched between two anchors in an east-west line. The optical phase of 1310 nm laser light was recorded from the output of two interferometers, one for each of two optical fibers in the 200-m-long sensing cable. The fibers differ in their temperature coefficients by about 15% to facilitate separation of phase change due to strain from that due to temperature. Four data files are included: phase1, phase2, temperature, and time. Each is sampled at 20 samples per second. View this collection on the contributor's website.
