Pendahuluan
Ko te Geophysics he peka o te pūtaiao whenua e ako ana i ngā āhuatanga ā-tinana o te Ao me tōna taiao mā te whakamahi i ngā tikanga ā-tinana. Ko tētahi āhuatanga nui o te geophysics ko te tūhuratanga i raro i te wai, he mea e ngāwari ana ki te pāngia e ngā momo wero nā te taiao ahurei. I roto i tēnei horopaki, ka noho te oro o raro i te wai hei taputapu nui. Ko te oro o raro i te wai, e mōhiotia ana ko te hydroacoustics, e whakamahi ana i ngā ngaru oro hei kimi, hei ine, hei tātari i ngā hanganga o raro i te wai. Ka matapakihia e tēnei tuhinga ngā mātāpono o te oro o raro i te wai me te whakamahinga o aua mātāpono ki te geophysics.
Ngā Mātāpono Taketake o te Oro o raro i te Wai
Ngā Ngaru Oro
He ngaru miihini te oro e horapa ana i roto i ngā mea e tere ana te oro, tae atu ki te wai. Ka rerekē te tere o te oro i roto i te wai i runga i te pāmahana, te tote, me te pēhanga wai. I te nuinga o te wā, ko te tere o te oro i roto i te wai moana he tata ki te 1500 mita ia hekona. Ka taea te whakarōpū i ngā ngaru oro mā te auau ki te infrasonic (auau iti), te audiosonic (auau waenga), me te ultrasonic (auau teitei).
Te Whakaata me te Whakaata
Ka pāngia ngā ngaru oro e rere ana i roto i te wai e te whakaata me te hurihanga ina tūtaki rātou ki ngā rerekētanga o te aukati oro, pērā i te rohe i waenganui i te wai me te papa moana, i ngā paparanga paru rerekē rānei. Ko te whakaata ko te pekepeketanga o ngā ngaru oro ki tō rātou pūtake, ko te hurihanga ko te piko o ngā ngaru oro i a rātou e haere ana i roto i ngā momo pāpāho.
