Voda je nujna za \u017eivljenje, zato je pomembno, da dobro skrbimo za na\u0161a morja, oceane, reke in jezera.<\/p>\n<\/div>\n<p>Da bi pri tem pomagala, je ESA v orbito okoli Zemlje izstrelila vesoljska plovila, kot so Sentinel. Njihova naloga je opazovati Zemljo iz vesolja in po\u0161iljati slike znanstvenikom na Zemlji. Podatki, ki jih zbirajo, se uporabljajo za spremljanje vodostajev, na\u010drtovanje ukrepov v primeru poplav ter zagotavljanje, da je na voljo dovolj vode za vse.<\/p>\n<p>Zdaj se vse bolj zavedamo velikega problema, s katerim se soo\u010dajo na\u0161i oceani: onesna\u017eevanje s plastiko. V zemeljske oceane se vsako leto odvr\u017ee okoli 10 milijonov ton plasti\u010dnih odpadkov. Plasti\u010dne odpadke je enostavno opaziti, ko jih morje izplavi na pla\u017ee, vendar jih je mogo\u010de najti tudi dale\u010d na odprtem morju. Nekateri so bili odkriti celo v zamrznjenem polarnem ledu!<\/p>\n<\/p>\n<p>Preberite, kako sateliti ESA pomagajo pri upravljanju z vodnimi viri. Avtorske pravice: konzorcij EO4SD-Water.<\/p>\n<p>Plastika v na\u0161ih oceanih se pod vplivom valov postopoma razgrajuje. Nato jo lahko po naklju\u010dju zau\u017eijejo ribe in druga morska bitja. Poleg tega, da je to \u0161kodljivo za te \u017eivali, plastika vstopi v prehranjevalno verigo, kar pomeni, da to vpliva tudi na druga \u017eiva bitja \u2013 vklju\u010dno z ljudmi.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"ESA - ScienceOffice.org\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/04\/Remote_sensing_of_marine_plastic_litter\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2018\/04\/remote_sensing_of_marine_plastic_litter\/17873039-2-eng-GB\/Remote_sensing_of_marine_plastic_litter.jpg\" alt=\"Remote sensing of marine plastic litter\"><figcaption>Daljinsko zaznavanje plasti\u010dnih odpadkov v morju<\/figcaption><\/figure>\n<p>Satelitski zemljevidi morskih tokov se \u017ee uporabljajo za napovedovanje, kje se bo odpadki kopi\u010dili v Tihem, Atlantskem in Indijskem oceanu. Znanstveniki upajo, da bodo lahko naredili \u0161e korak naprej in preverili, ali lahko sateliti neposredno zaznavajo onesna\u017eenje s plastiko, ki plava v zemeljskih morjih. Sateliti ESA bi to posku\u0161ali dose\u010di s preu\u010devanjem infrarde\u010de svetlobe, ki jo odbijajo odpadki, in iskanjem posebnega \u201cprstnega odtisa\u201d, ki ka\u017ee na prisotnost plastike. Ta tehnologija se \u017ee uporablja v recikla\u017enih obratih za lo\u010devanje razli\u010dnih vrst plastike.<\/p>\n<p>\u010ce bo to delovalo, bomo lahko izdelali natan\u010den zemljevid zemeljskih oceanov, na katerem bo prikazano, kje plavajo plasti\u010dni odpadki.
