Glacier, सियाचिन ग्लेसियर, Self-monitoring, analysis and reporting technology

सियाचिन ग्लेसियर :  स्मार्ट (Self-monitoring, analysis and reporting technology ) ग्लेसियर?

Smart glaciers

Masi kagad chhuyo nahin, kalam gahi nahi haath….मसि कागद छुयो नहीं कलम गही नहि हाथ. 

Kabir das
While writing this article, I remember the above mentioned line of Kabir. It is apparent that his couplets were not written by him but his followers.  His couplets are still prevalent in the society that needs to be corrected even after  more than 500 years.  Similarly, in the context of proposing a probable solution for reducing the tragedies from the Glaceir avalances, land slides after cloud bursts, eventhough I have not worked on the area but propose the following. 

Avalanche in Siachen and deaths of soldiers

After the avalanche in Siachen glacier  of 3rd Feb, whole country has become highly sensitive about this issue as well as about the working conditions of the Army in India and its neighbourhood.   Besides 10 soldiers we lost in the recent disaster, over hundred were lost by our neighbour in Gayari.  It is proposed here that one of the solutions is to give alarm by more than 24 hours or even more to the inhabitants of such risky hills (including Himalayan range, border roads, or even Badrinath route).  These routes are very often blocked by the land erosion that comes after heavy rains or as a result of global warming.  Timely monitoring by the type of sensors described below can save the priceless lives as well as loss of property in some cases.

The smart pipes, smart bridges, smart tapes, smart port- why not smart galciaers, smart hills?
Self-monitoring, analysis and reporting technology or, briefly SMART is the budge word of today.  When you can have optical fibre running across the meditarian/ atlantic, why not along a few slops of glaciers?
Photonics
One of the fast developing areas of science and technology in which physics and electrical engineering departments are working throughout the word is known as PHOTONICS.  In recent years, FIBER Optics has revolutionased the high speed internet and telecon and mobile phone technology.  Neck to neck are the developments in sensor technology with fibre optics.
Nobel Prize by Braggs and fibre Bragg Gratings (FBG)
Father – son got the Noble Prize in 1915 for an equation known as Bragg’s law (nλ = 2d sinθ) while working with X-rays.  For wavelengths of the order of visible or near IR raidations, similar structures can be made in fibres.  If we send a light beam at 90 degrees , depending on the spacing of the Bragg structure, some portion of light can return or pass.  The behaviour depends on the stress/ deterioration caused by any external parameter (temperature, stress, gas leak etc.).  This kind of sensing is known as fibre Bragg grating (FBG) sensing and is popular in various areas as mentioned above.  Solar operatted batteries can be used and usual maintenance can help this kind of project. 
Install FBG across the hillocks/ glaciers and monitor them
Nothing stops from throwing  (installing) some FBG lines on the blue glaciers (that re harder than concrete but break occasionally) and monitoring their health from this economic technology to safeguard our invaluable soldiers who are already under severe stress at such high battle fields.  Both India and Pakistan or even other countries should look for this technology and lay down some of these lines across  hills near such glacier posts and ,hills that are prone to soil erosion.   As a test cases, this technology must be quickly checked in hillocks near the cities, research centers etc.  Scientists might have to take their  position out of their comfort zones , i.e. labs or class rooms!  Yes, some things are difficult, very difficult.
Some defense lab must take up this project and implement as fast as possible.
Glaciers for sports and Army activity
If you google for “glaciers deaths” you will realise that glaciers have become integral part of the sports and, of course army after the well sought positions of Siachen were taken by Indian army during  and after 1984.

Surviving with Chocolates 
None of the two countries' citizen want their sons to be stationed at 18-24000 feet above the sea level.  Here, barely the living becomes a battle with oneself.  Soldiers stop eating food as for Indian way of cleanliness after the natures' call becomes difficult!  The avalanches make this thought process  even miserable.

Best wishes,

Prem
