Baltijos j\u016bra. Eltos nuotr.<\/p>\n

Neseniai \u017eurnale \u201eFrontiers in Earth Science” paskelbtas tyrimas rodo, kad giliuose centrin\u0117s Baltijos j\u016bros dalies vandenyse deguonies kiekis per pastar\u0105j\u012f de\u0161imtmet\u012f spar\u010diai ma\u017e\u0117jo, o dabartinis stagnacijos laikotarpis, prasid\u0117j\u0119s 2016 m., suk\u0117l\u0117 did\u017eiausi\u0105 deguonies tr\u016bkum\u0105 matavim\u0173 istorijoje.<\/p>\n

\u00a0<\/p>\n

Tyrim\u0105, bendradarbiaudami su kolegomis i\u0161 Suomijos ir Latvijos, atliko Tavio Libliko (Taavi Liblik) vadovaujami mokslininkai i\u0161 Talino technikos universiteto J\u016br\u0173 sistem\u0173 instituto.<\/p>\n

\u201eSutapus keliems veiksniams deguonies tr\u016bkumas daugiau nei 100 m. gylyje tapo bepreceden\u010diai dideliu. Giliajame sluoksnyje susidar\u0117 vandens mas\u0117 su dideliu vandenilio sulfid\u0173 kiekiu, kurioje deguonies tr\u016bkumas siekia 2,5 mln. ton\u0173”, – pabr\u0117\u017e\u0117 T.Liblikas.<\/p>\n

Tai l\u0117m\u0117 kelios prie\u017eastys. Deguonis negali prasiskverbti \u012f gilesnius Baltijos j\u016bros sluoksnius, nes vanduo susisluoksniavo: ry\u0161kus druskingumo pokytis veikia kaip \u201edangtis”, nepraleid\u017eiantis deguonies i\u0161 pavir\u0161iaus \u012f apa\u010di\u0105.<\/p>\n

Deguonies deficito augim\u0105 skatina ir kiti veiksniai. I\u0161 \u0160iaur\u0117s j\u016bros \u012f Baltijos j\u016br\u0105 nepatenka pakankamai deguonimi prisotinto vandens, kuris kitomis s\u0105lygomis pad\u0117t\u0173 \u201ev\u0117dinti” giliuosius sluoksnius. Gelm\u0117s \u0161yla, o \u0161iltame vandenyje deguonies yra ma\u017eiau.<\/p>\n

Be to, \u0161iluma skatina organini\u0173 med\u017eiag\u0173 skilim\u0105, o tam irgi reikalingas deguonies. Visa tai vyksta tokiomis s\u0105lygomis, kai antropogenin\u0117s maistin\u0117s med\u017eiagos, pavyzd\u017eiui, gaunamos i\u0161 \u017eem\u0117s \u016bkio, lemia dar didesn\u012f organini\u0173 med\u017eiag\u0173 kaupim\u0105si, o pastarosios nus\u0117dusios \u012f dugn\u0105 eikvoja gili\u0173j\u0173 vanden\u0173 deguonies atsargas.<\/p>\n

Kyla klausimas – ar situacija gali pager\u0117ti?<\/p>\n

Pasak mokslinink\u0173, greitai tai ne\u012fvyks. Baltijos j\u016bra priklauso nuo intak\u0173 i\u0161 \u0160iaur\u0117s j\u016bros, kurie \u012f giliuosius sluoksnius atne\u0161a \u0161vie\u017eio vandens ir deguonies. Giliuose sluoksniuose jau susidar\u0117 reik\u0161mingas deguonies deficitas ir net labai stiprus antpl\u016bdis, tikriausiai negal\u0117t\u0173 visi\u0161kai jo kompensuoti.<\/p>\n

Taip pat t\u0119siasi klimato at\u0161ilimas, kas irgi u\u017ekerta keli\u0105 pad\u0117ties ger\u0117jimui. Visgi galimyb\u0117 ilgainiui pakeisti situacij\u0105 yra.<\/p>\n

Tam reikia, kad Baltijos regiono \u0161alys ir toliau ma\u017eint\u0173 tar\u0161\u0105 bei ribot\u0173 maistini\u0173 med\u017eiag\u0173 patekim\u0105 \u012f j\u016br\u0105.<\/p>\n","protected":false},"excerpt":{"rendered":"1 nuotr.
