\u00cen timpul campaniei din 2022, Ran a operat timp de 27 de zile sub platforma Dotson, p\u0103trunz\u00e2nd p\u00e2n\u0103 la aproximativ 11 mile \u00een interiorul cavit\u0103\u021bii subglaciare. \u00cen aceast\u0103 perioad\u0103, vehiculul a cartografiat aproximativ 139,86 de kilometri p\u0103tra\u021bi de suprafa\u021b\u0103 inferioar\u0103 a ghe\u021bii.<\/p>\n
Datele ob\u021binute au ar\u0103tat o structur\u0103 mult mai complex\u0103 dec\u00e2t modelele simplificate utilizate anterior \u00een cercetare. Sub stratul de ghea\u021b\u0103 au fost identificate platouri, trepte \u0219i depresiuni alungite, formate prin topirea de la baz\u0103. \u00cen partea estic\u0103 \u0219i central\u0103 a platformei, relieful apare sub forma unor terase suprapuse, \u00een timp ce \u00een vest suprafa\u021ba este mai uniform\u0103, cu canale \u0219i zone erodate mai intens.<\/p>\n<\/div>\n
Aceste diferen\u021be sunt asociate cu circula\u021bia apei oceanice. Observa\u021biile satelitare indic\u0103 o rat\u0103 de sub\u021biere de aproximativ 12.192 metri pe an \u00een unele zone ale Dotson.<\/p>\n

Datele indic\u0103 o eroziune inegal\u0103, mai accentuat\u0103 pe partea vestic\u0103, unde curen\u021bii concentreaz\u0103 fluxul de ap\u0103 mai cald\u0103.<\/p>\n
