Environmental and Earth Sciences

Silixa has been devoted to the environment and earth sciences since its inception. Our solutions deliver vital information to assess environmental conditions and trends, help tackle global climate change challenges and predict environmental hazards.

Our high-sensitivity distributed fibre optic sensing-based solutions find numerous applications in the environmental and earth sciences sectors and have been deployed worldwide.

When installed as a permanent monitoring solution, Silixa’s distributed fibre optic sensing-based systems can function as an effective warning system, hence saving lives, reducing environmental damage and economic losses.

Why use distributed sensing?

Fibre optic sensing is an innovative technology and there are no alternatives that are as cost-effective, technically feasible, and easy to apply in the environmental sector where most processes require high-precision measurements on scales ranging from centimetres to tens of kilometres.

Distributed acoustic (DAS) and temperature (DTS) systems offer high spatial and temporal profiling over large surfaces, long lengths and at locations where conventional point sensing is not applicable or cost effective.

Fibre optic sensing is also well suited for harsh environments and can support scientific work in the most inhospitable environments such as volcanic hot springs or glaciers with minimal environmental impact.

Advancements in DAS enabling new geophysical and geotechnical applications

The advancements in Silixa’s phase-coherent iDAS technology in the recent years have opened new perspectives for several geophysical and geotechnical applications.

The ability to collect high resolution acoustic data utilising dark fibers over very long ranges is invaluable. It enables continuous, remote seismic monitoring of the Earth’s near surface, even in highly populated areas, hence delivering better understanding of the subsurface. This not only offers more precise insight into the effects of climate change but also helps predict environmental hazards such as earthquakes, tsunamis or landslides.

In urban areas, continuous seismic monitoring can also be used to monitor hydrological systems, traffic flow, sediment transport in ports, and canal erosion.

Silixa’s DTS systems, the instruments of choice

Silixa’s distributed temperature sensing systems, with the highest accuracy and resolution performance in the market, have also been the instrument of choice for a number of environmental applications, such as soil moisture monitoring, atmospheric measurements, thermocline profile reproduction in lakes, seepage rate estimation in dams, groundwater-surface water interactions in streams, shallow thermocline environments, fractured rock characterisation and flow dynamics into boreholes.

Climate change challenges

Understanding climate change and its dramatic consequences is the first step towards environmental sustainability.

Silixa’s environmental and Earth sciences’ solutions provide a tool to scientist to solve some of the world’s most pressing environmental issues, including the effect of human activity on the environment.

By assessing environmental conditions and delivering accurate insight into processes our solutions provide vital intelligence to society that can help combat the climate change challenges.

By applying our expertise and innovative technologies to gathering Earth science knowledge we also support policy development and its implementation.


Earthquakes, tornadoes, tsunamis, volcanic eruptions and other natural phenomena have caused millions of deaths and massive damage to the environment and infrastructure. Hence, effective monitoring and warning systems will remain key in delivering vital information on such hazards.

Silixa’s distributed sensing-based solutions increase safety by delivering actionable insight into environmental processes and trends. In numerous applications our cutting-edge fibre optic solutions serve as early warning systems,minimising environmental damage and potential loss of life. They also protect infrastructure from catastrophic damage and costly repairs.

Environmental protection

From detecting contaminated groundwater entering streams and rivers, to providing insight into climate change through monitoring the melting of glacial ice in the Antarctic, Silixa’s instrumentation and environmental geosciences expertise can be utilized to reduce direct anthropogenic impacts to our environment.

By doing so we also guide long-term policy to improve and protect the natural world we share for generations to come.
