Hi Mexi, Cessy n Saut
iya nih seperti yang disampaikan oleh Cessy, metode ini menggunakan gelombang suara yang ditembakkan ke dasar laut dan akan dikembalikan ke receivernya, mirip sonar. Ide nya adalah bahawa batuan dengan Hc memiliki properti yang berbeda dalam memantulkan gelombang suara tersebut sehingga dapat di bedakan mana yang berasal dari daerah yang memiliki HC atau tidak. Multibeam technologi ini mengclaim bisa membuat peta topografi dasar laut dengan akurasi yang tinggi dan menawarkan coring pada daerah yg teridentifikasi sebagai seepage di dasar laut.

tentang Barrow delta, nah itu ada di laporan disini nanti pv ya, hahahahaha

Mexi!!!

Mexi, in a report I’ve read about these multibeams Illo mentioned about; the physical and geophysical attributes of the seafloor could be affected by these fluid seepages and its biologic and mineralogic manifestations. once the multibeams were map, we will be able to identify anomalous bathymetry that might be related to seepage, because the seep occurrence will affect the seafloor roughness and impedance.
Not much of an info isn’t it, but I’m sorry, I can give you a full report. But I’ll email you the references cited on the report. Is that OK?

Hi ilo, bloody brilliant.. anyway do we have oil seepages on seafloor in NW Shelf, since I’m concern in Barrows Subbasin and how to determine those seepages through multibeam? cheers
