Ka maakera koores leiduvad magnetiseeritud kivimid avaldavad sellele v\u00e4ikest m\u00f5ju. Kas teadsite, et ka merevesi on magnetismi allikas? Kui soolane merevesi voolab l\u00e4bi Maa magnetv\u00e4lja, tekib elektrivool, mis omakorda tekitab magnetj\u00f5udu. See on v\u00e4ga v\u00e4ike ja uskumatult raske m\u00f5\u00f5ta, kuid Swarm-satelliidid on just seda teinud.<\/p>\n<p>Magnetv\u00e4ljade kaardistamine ookeani pinnast merep\u00f5hja on v\u00f5imaldanud teadlastel avastada, kuidas vesi voolab k\u00f5ikidel s\u00fcgavustel \u2013 see on t\u00e4iesti uus teave. Ookeanid neelavad \u00f5hust soojust, seega on soojuse leviku j\u00e4lgimine ookeanides oluline osa Maa kliima paremast m\u00f5istmisest. Swarm-missiooni viimased tulemused aitavad meil isegi saada teavet Maa koore ja selle vahetult all asuva piirkonna \u2013 litosf\u00e4\u00e4ri \u2013 elektriliste omaduste kohta. Tegelikult on Swarm koostanud uue kaardi Maa koore poolt tekitatud magnetv\u00e4ljast!<\/p>\n<\/p>\n<p>Swarm on kaardistanud, kuidas Maa magnetv\u00e4li muutub 24 tunni jooksul.
