Climate change is posing new challenges to cities all over the world. Learn how this fiber optic cable can assist with essential scientific research.
Year after year temperatures have been rising in the Arctic. This has triggered a thawing in the icebergs, permafrost, and the degrading of various infrastructures. Scientists have turned to a fiber optic cable to help monitor these changes.
When a fiber cable breaks the operator must first pinpoint the location of the issue. To check a cable within a fiber optic infrastructure the cable-operator can send a series of light pulses to test for inconsistencies. This same theory is being applied to monitor the permafrost defrost.
The telecom cable will be used to collect seismic data with laser pulses in a technique called distributed acoustic sensing. This method will allow Professor Ming Xiao and her research team to monitor seismic interruptions within the soil. With this continuously collected data, the team will be able to detect permafrost temperature, various soil parameters, and seismic wave velocity. This research will inevitably expose essential patterns to help predict the behavior of future infrastructure thawing in the Arctic.
