INSEA Smart Cable campaign
Abstract
The wet demo SMART (Science Monitoring And Reliable Telecommunications, https://www.smartcables.org/) cable is a cable similar to telecom commercial cables the numerous ones used for telecommunications, approximately 18 km long in which 3 sets of geophysical sensors are integrated. Each set is positioned inside commercial telecom the classic repeaters at a distance of 6 km from each other. of a telecommunications cable (every 6km) and
eEach set is composed by:
- a wide-band triaxial accelerometer,
- a broadband triaxial seismometer,
- a pressure sensor,
- a temperature sensor.
Combining measurements of seafloor temperature, pressure, and ground acceleration can enhance our understanding of ocean circulation, heat storage, tsunami detection, and earthquake hypocenter determination.
Purpose
This is the first prototype of a mini- SMART cable laid in the world and aims to demonstrate that sets of geophysical sensors inserted into underwater telecommunications cables provide high-quality data. Moreover the project aimed to demonstrate that SMARTthe cables can be deployed in a commercially standard manner without compromising the scientific value of the data being transmitted by the sensors.
