Telkiniuose, kurie per t\u016bkstantme\u010dius susiformavo po vis\u0173 pasaulio j\u016br\u0173 dugnu, yra did\u017eiuliai kiekiai metano. \u0160ios nematomos, klimat\u0105 ter\u0161ian\u010dios dujos gali i\u0161siskirti \u012f vanden\u012f per \u012ftr\u016bkimus j\u016bros dugne, da\u017enai pasirodydamos burbuliuk\u0173 srautu, kylan\u010diu \u012f pavir\u0161i\u0173.<\/p>\n
Apie \u0161iuos povandeninius i\u0161siskyrimus, j\u0173 veikim\u0105, skai\u010di\u0173 ir metano kiek\u012f, kuris patenka \u012f atmosfer\u0105, palyginti su kiekiu, kur\u012f suvartoja metan\u0105 vartojantys mikroorganizmai, gyvenantys vandenyne, \u017einoma palyginti nedaug.<\/p>\n
Metano nuot\u0117kiai Antarktidoje yra vieni i\u0161 ma\u017eiausiai i\u0161tirt\u0173 planetoje, tod\u0117l tarptautin\u0117 mokslinink\u0173 komanda nusprend\u0117 juos surasti. Jie naudojo laivuose \u012frengtus akustinius prietaisus, nuotoliniu b\u016bdu valdomus aparatus ir narus, kad paimt\u0173 m\u0117ginius i\u0161 \u012fvairi\u0173 viet\u0173 Roso j\u016broje.<\/p>\n
J\u0173 atradimai nustebino juos pa\u010dius. Mokslininkai nustat\u0117 daugiau nei 40 metano nuot\u0117ki\u0173 Roso j\u016bros sekliuose vandenyse, kaip teigiama \u0161\u012f m\u0117nes\u012f \u017eurnale \u201eNature Communications\u201c paskelbtame tyrime.<\/p>\n
Daugelis nuot\u0117ki\u0173 buvo rasti vietose, kurios buvo ne kart\u0105 tiriamos anks\u010diau, o tai rodo, kad nuot\u0117kiai nauji. Tai gali reik\u0161ti \u201eesmin\u012f pokyt\u012f\u201c metano i\u0161siskyrime regione, teigiama ataskaitoje.<\/p>\n
Metano nuot\u0117kiai yra gana paplit\u0119 visame pasaulyje, ta\u010diau anks\u010diau Antarktidoje buvo patvirtintas tik vienas aktyvus nuot\u0117kis, teig\u0117 ataskaitos autor\u0117 ir j\u016br\u0173 mokslinink\u0117 i\u0161 mokslini\u0173 tyrim\u0173 organizacijos \u201eEarth Sciences New Zealand\u201c Sarah Seabrook. \u201eTai, kas buvo laikoma retu rei\u0161kiniu, dabar, atrodo, tampa pla\u010diai paplitusiu\u201c, \u2013 ji sak\u0117 CNN.<\/p>\n
Kiekvienas j\u0173 aptiktas nuot\u0117kis sukeldavo \u201egreit\u0105 entuziazm\u0105\u201c, kuris \u201egreitai virsdavo nerimu ir susir\u016bpinimu\u201c, sak\u0117 mokslinink\u0117.<\/p>\n
Baiminamasi, kad \u0161ie nuot\u0117kiai gali greitai perkelti metan\u0105 \u012f atmosfer\u0105, tod\u0117l jis taps planet\u0105 \u0161ildan\u010dio u\u017eter\u0161imo \u0161altiniu, kuris \u0161iuo metu n\u0117ra \u012ftrauktas \u012f ateities klimato kaitos prognozes.<\/p>\n
Mokslininkai taip pat yra susir\u016bpin\u0119, kad metanas gali tur\u0117ti did\u017eiul\u012f poveik\u012f j\u016br\u0173 gyv\u016bnijai.<\/p>\n
N\u0117ra ai\u0161ku, kod\u0117l \u0161iame regione atsiranda metano nuot\u0117kiai, ta\u010diau mokslininkai tiria, ar juos gali paveikti klimato kaita.<\/p>\n
Kitoje pasaulio pus\u0117je, Arktyje, padid\u0117j\u0119s metano i\u0161siskyrimas i\u0161 po \u017eem\u0117s buvo susietas su klimato kaitos poveikiu, sak\u0117 S.Seabrook, \u012fskaitant \u0161iltesnes temperat\u016bras, j\u016bros lygio poky\u010dius.<\/p>\n
Tai gali sukurti gr\u012f\u017etamojo ry\u0161io kilp\u0105, prid\u016br\u0117 S.Seabrook, kai klimato kaita didina metano nuot\u0117k\u012f, o tai savo ruo\u017etu dar labiau didina klimato kaitos temp\u0105.<\/p>\n
Mokslininkai v\u0117l gr\u012f\u017eta \u012f Antarktid\u0105 dviem m\u0117nesiams, kad i\u0161samiau i\u0161tirt\u0173 nuot\u0117kius.<\/p>\n","protected":false},"excerpt":{"rendered":"Telkiniuose, kurie per t\u016bkstantme\u010dius susiformavo po vis\u0173 pasaulio j\u016br\u0173 dugnu, yra did\u017eiuliai kiekiai metano. \u0160ios nematomos, klimat\u0105 ter\u0161ian\u010dios…\n","protected":false},"author":2,"featured_media":32221,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15],"tags":[25,30,31,34,35,24,32,33,37,39,36,38,40,23,22,44,28,29,26,27,74,75,76],"class_list":{"0":"post-32220","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-pasaulis","8":"tag-antrastes","9":"tag-breaking-news","10":"tag-breakingnews","11":"tag-featured-news","12":"tag-featurednews","13":"tag-headlines","14":"tag-latest-news","15":"tag-latestnews","16":"tag-lietuva","17":"tag-lietuviu","18":"tag-lithuania","19":"tag-lithuanian","20":"tag-lt","21":"tag-naujienos","22":"tag-news","23":"tag-pasaulis","24":"tag-populiariausios-naujienos","25":"tag-populiariausiosnaujienos","26":"tag-top-stories","27":"tag-topstories","28":"tag-world","29":"tag-world-news","30":"tag-worldnews"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@lt\/115490822880419186","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/posts\/32220","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/comments?post=32220"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/posts\/32220\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/media\/32221"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/media?parent=32220"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/categories?post=32220"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/lt\/wp-json\/wp\/v2\/tags?post=32220"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
