Turashobora kubona komisiyo ishinzwe mugihe uguze kumurongo wurubuga rwacu.Dore uko ikora.
Ubushakashatsi bushya bwerekanye ko Pole y'Amajyaruguru yegamiye kuri Siberiya kuva mu rugo rwayo gakondo muri Arctique ya Kanada kuko amatsinda abiri manini yihishe munsi y’ubutaka ku mupaka wa mantle yishora mu ntambara.
Iyi myanya, uduce twinshi twa magnetiki itari munsi ya Kanada na Siberiya, igira uruhare mukurwana-gutsinda-byose.Nkuko ibitonyanga bihindura imiterere nimbaraga za magnetique, hari uwatsinze;Abashakashatsi basanze mu gihe ubwinshi bw’amazi munsi ya Kanada bwacogoye kuva mu 1999 kugeza muri 2019, ubwinshi bw’amazi munsi ya Siberiya bwiyongereyeho gato kuva mu 1999 kugeza 2019. Abashakashatsi banditse bati: “Hamwe na hamwe, izo mpinduka zatumye Arctique yerekeza kuri Siberiya.” mu bushakashatsi.
Muri email ye, Phil Livermore, umushakashatsi wungirije akaba n'umwarimu wungirije wa geofiziki muri kaminuza ya Leeds mu Bwongereza, yabwiye Live Science ati: "Ntabwo twigeze tubona ibintu nk'ibi mbere."
Igihe abahanga bavumbura bwa mbere Pole y'Amajyaruguru (aho urushinge rwa kompasse) mu 1831, ni mu majyaruguru ya Kanada ya Nunavut.Abashakashatsi ntibatinze kubona ko inkingi ya rukuruzi ya ruguru yakunze kugenda, ariko mubisanzwe ntabwo iri kure cyane.Hagati ya 1990 na 2005, umuvuduko inkingi za rukuruzi zagendaga zisimbuka uva ku muvuduko w’amateka utarenze kilometero 9 (15 km) ku mwaka ugera ku bilometero 37 (60 km) ku mwaka, abashakashatsi banditse mu bushakashatsi bwabo.
Mu Kwakira 2017, inkingi ya rukuruzi ya ruguru yarenze umurongo mpuzamahanga w’amatariki mu gice cy’iburasirazuba, inyura mu bilometero 242 (kilometero 390) uvuye mu majyaruguru.Noneho amajyaruguru ya magnetiki pole atangira kwerekeza mumajyepfo.Hahindutse byinshi kuburyo muri 2019, abahanga mu bumenyi bwa geologiya bahatiwe kurekura umwaka hakiri kare moderi nshya yisi ya magnetiki yisi, ikarita ikubiyemo ibintu byose kuva kuguruka kwindege kugeza kuri GPS GPS.
Umuntu arashobora gusa gukeka impamvu Arctique yavuye muri Kanada yerekeza muri Siberiya.Nibwo kugeza igihe Livermore na bagenzi be bamenye ko ibitonyanga ari byo nyirabayazana.
Umwanya wa rukuruzi ukorwa nicyuma cyamazi kizunguruka mu nsi yisi yisi.Rero, impinduka mubwinshi bwicyuma kizunguruka gihindura imyanya ya magnetiki mumajyaruguru.
Nyamara, magnetiki yumurima ntabwo igarukira kumurongo.Nk’uko Livermore abivuga, imirongo ya rukuruzi ya “magnet” ivuye ku isi.Biragaragara ko ibitonyanga bigaragara aho iyi mirongo igaragara.Ati: "Niba utekereza imirongo ya magneti nka spaghetti yoroshye, ibibara bimeze nkibice bya spaghetti biva ku isi".
Abashakashatsi basanze kuva mu 1999 kugeza 2019, agace kari munsi ya Kanada kavuye mu burasirazuba kugera mu burengerazuba maze kagabanyamo uduce tubiri duto duhujwe, bishoboka ko byatewe n’imihindagurikire y’imiterere y’imigezi minini hagati ya 1970 na 1999. Kimwe muri ibyo bibanza cyari gikomeye kurusha u ibindi, ariko muri rusange, kurambura “byagize uruhare mu gucika intege kwa Kanada ku isi”, abashakashatsi banditse muri ubwo bushakashatsi.
Byongeye kandi, ikibanza cya Kanada cyarushijeho kuba hafi ya Siberiya kubera gutandukana.Abashakashatsi banditse ko ibyo na byo byashimangiye umwanya wa Siberiya.
Abashakashatsi banditse muri ubwo bushakashatsi ariko, ibyo bice byombi biri mu buringanire bworoshye, bityo rero "guhindura bike gusa ku miterere y'ubu birashobora guhindura inzira igezweho ya Pole y'Amajyaruguru yerekeza muri Siberiya".Muyandi magambo, gusunika kumurongo umwe cyangwa kurundi birashobora kohereza magnetiki mumajyaruguru gusubira muri Kanada.
Kwiyubaka kwimikorere ya magnetiki ya pole yashize kuri Pole y'Amajyaruguru byerekana ko ibitonyanga bibiri, ndetse rimwe na rimwe, byagize ingaruka kumwanya wa Pole y'Amajyaruguru mugihe.Abashakashatsi bavuga ko mu myaka 400 ishize, ibitonyanga byatumye Pole y'Amajyaruguru itinda mu majyaruguru ya Kanada.
Abashakashatsi banditse muri ubwo bushakashatsi bati: “Ariko mu myaka 7000 ishize, [Pole y'Amajyaruguru] isa nkaho yazengurutse inkingi ya geografiya mu buryo butemewe iterekanye aho ikunda.”Ukurikije icyitegererezo, mu 1300 mbere ya Yesu, inkingi nayo yerekeje muri Siberiya.
Biragoye kuvuga ibizakurikiraho.Livermore yagize ati: "Ibyo duhanura ni uko inkingi zizakomeza kwerekeza muri Siberiya, ariko guhanura ibizaza biragoye kandi ntidushobora kubyemeza neza".
Abashakashatsi banditse mu bushakashatsi bwasohotse ku rubuga rwa interineti ku ya 5 Gicurasi mu kinyamakuru Nature Geoscience banditse ku bushakashatsi bwakozwe ku rubuga rwa interineti ku ya 5 Gicurasi.
Mugihe gito, urashobora kwiyandikisha mubinyamakuru byacu bigurishwa cyane mubinyamakuru bya siyansi byibuze $ 2.38 buri kwezi cyangwa 45% kubiciro bisanzwe mumezi atatu yambere.
