Majhen vpliv imajo tudi magnetizirane kamnine v zemeljski skorji. Ali ste vedeli, da je tudi morska voda vir magnetizma? Ko slana morska voda te\u010de skozi Zemljino magnetno polje, nastane elektri\u010dni tok, ki nato ustvari magnetno silo. Ta je zelo majhna in izjemno te\u017eko merljiva, vendar so sateliti Swarm ravno to uspeli.<\/p>\n<p>Z kartiranjem magnetnih polj od morske povr\u0161ine do morskega dna so znanstveniki odkrili, kako voda te\u010de na vseh globinah, kar predstavlja povsem nove informacije. Oceani absorbirajo toploto iz zraka, zato je spremljanje \u0161irjenja toplote po oceanih pomemben del bolj\u0161ega razumevanja zemeljskega podnebja. Najnovej\u0161i rezultati misije Swarm nam celo pomagajo spoznavati elektri\u010dne lastnosti zemeljske skorje in obmo\u010dja tik pod njo \u2013 obmo\u010dja, imenovanega litosfera. Swarm je namre\u010d izdelal nov zemljevid magnetnega polja, ki ga ustvarja zemeljska skorja!<\/p>\n<\/p>\n<p>Podjetje Swarm je prikazalo, kako se zemeljsko magnetno polje spreminja v obdobju 24 ur.
