Kutshanje, kuye kwafunyaniswa ukuba iintambo eziqhelekileyo zefiber optic zinokusebenza njengezixhobo zoluvo lwe-seismic. Ukungcangcazela kuqweqwe lomhlaba kuchaphazela intambo ebekwe kwindawo yomsebenzi kwaye kubangele ukutenxa kwinqanaba lokusasazwa komqadi wokukhanya kwii-waveguides. Isixhobo sithatha ezi zitenxo kwaye zichonge njengomsebenzi wenyikima. Kuvavanyo olwenziwa kunyaka ophelileyo, umzekelo, ukusebenzisa iintambo zefiber-optic ezibekwe emhlabeni, kwakunokwenzeka ukurekhoda namanyathelo abahambi ngeenyawo.
Kwagqitywa ukuba kuvavanywe olu phawu lweentambo ze-optical ukuvavanya ukuziphatha kwee-glaciers - kulapho intsimi ingalinywanga. Imikhenkce ngokwazo isebenza njengezalathi zokutshintsha kwemozulu. Ummandla, umthamo kunye nokushukuma (iimpazamo) kwezona ndawo zinkulu zomkhenkce eMhlabeni zibonelela ngolwazi oluxabisekileyo lokuqikelela imozulu yexesha elide kunye nokuqikelela ukuguquka kwemozulu. Ekuphela kwento embi kukuba ukujonga umkhenkce usebenzisa izixhobo zesiqhelo zenyikima kuyabiza kwaye akufumaneki kuyo yonke indawo. Ingaba iintambo zefiber optic ziyakunceda kule nto? Iingcali ezivela kwi-Swiss Federal Institute of Technology Zurich (ETH Zurich) zazama ukuphendula lo mbuzo.
Iqela lezazinzulu ezikhokelwa ngu-Andreas Fichtner, uprofesa kwiLebhu yeHydraulics, Hydrology kunye neGlaciology kwi-ETH Zurich, waya kwi-Glacier yaseRhone. Ngexesha lovavanyo, kwafumaniseka ukuba iintambo zefiber optic zingaphezulu kwezixhobo ezigqwesileyo zokurekhoda umsebenzi we-seismic. Ngaphezu koko, intambo ebekwe phezu kwekhephu kunye nomkhenkce phantsi kokufudumeza kwelanga ngokwalo yanyibilika emkhenkceni, nto leyo iyimfuneko ngokupheleleyo ekusebenzeni kwenethiwekhi enjalo yezinzwa.
Uthungelwano oludaliweyo lwezinzwa ezineendawo zokurekhoda zokungcangcazela kunyuso lwemitha enye ecaleni kobude bentambo zavavanywa ngothotho loqhushumbo olulinganisa iimpazamo kumkhenkce. Iziphumo ezifunyenweyo zigqithise konke obekulindelwe. Ngaloo ndlela, kungekudala izazinzulu zinokuba nezixhobo eziya kunceda ukulandelela umkhenkce ngokuchaneka okuphezulu nokulumkisa ngeenyikima kumanqanaba okuqala okwenziwa koqweqwe lwamatye.
