Ngemva kwezingxabano ezinde kanye nokushicilelwa kwemibono engqubuzanayo, izazi zasolwandle nokho zafinyelela ukuvumelana, okwakuyimbangela yomsindo “wensimbi” owaqoshwa eminyakeni engu-2 edlule endaweni yaseMariana Trench.
Umsindo ongaqondakali waqoshwa ngesikhathi sokusebenza kwemoto ejulile yolwandle esikhathini sika-2014-2015. endaweni ejulile yolwandle etholakala empumalanga yePacific Ocean. Isikhathi somsindo orekhodiwe sasiyimizuzwana engu-3.5. Yayinezingxenye ezi-5 ezihlukene ngezici zazo, ebangeni lemvamisa ukusuka ku-38 kuye ku-8 Hz.
Ngokusho kwenguqulo yakamuva, umsindo wenziwa umkhomo ovela emndenini wama-minke whale - i-northern minke whale. Kuze kube manje, akukho okuningi okwaziwayo mayelana "nemilutha yakhe yamazwi" kwisayensi.
Njengoba uchwepheshe we-marine bioacoustics evela e-Oregon Research University (USA) echaza, isignali ethwebuliwe iyahluka kuneyake yaqoshwa ngaphambilini mayelana nomsindo oyinkimbinkimbi kanye nesici “sensimbi” yetimbre.
Izazi zasolwandle azikaqiniseki ngamaphesenti angu-100 ukuthi umsindo oqoshiwe wawusho ukuthini. Phela, imikhomo “icula” kuphela ngesikhathi sokuzalanisa. Mhlawumbe isignali yayinomsebenzi ohluke ngokuphelele.
