Si kastaba ha noqotee, koox ka mid ah bayoolajiyada badda, oo ay hoggaaminayaan Mary Ann Daher oo ka tirsan Machadka Oceanographic ee Woods Hole, ayaa ku soo warramay New Scientist bishii Diseembar 2004 in ay raad-raacayeen nibiri ku yaal Waqooyiga Baasifigga muddo 12 sano ah oo "heesaya" 52 Hz. Saynisyahannadu ma awoodaan inay sharxaan farqigaas caadiga ah; si kastaba ha noqotee, waxay aaminsan yihiin in nibirigu yahay nibiriga oo aan u muuqan inuu yahay nooc cusub, taasoo soo jeedineysa in noocyada hadda la yaqaan ay yeelan karaan heerar cod oo ka ballaaran intii hore loo maleynayay. Waxaa jira khilaaf ku saabsan bulshada ee nibiriga ee codka deegaanka iyo in ay tahay mid ka mid ah codadka qoto dheer ee nibiriga buluugga ah ee laga maqlo inta lagu jiro muddada dheer ee muddada dheer iyo muddada gaaban ee cilmi baarista.
