摘要: We present some of the latest developments in marine instrumentation for geophysical instrumentation, and their evolutions. For several years, we have been developing magnetotelluric seafloor instruments. Initially deep mantle studies, recording at low frequency with long term instruments, more recently crustal studies industrial exploration high recording. are also currently electromagnetic observatories. Thanks to collaborations Pacific Marine Environmental Laboratory (NOAA & Oregon State University) Newport, (USA) acquired knowledge contact autonomous hydrophones monitor seismicity oceanic areas population mammals. All these investigation technical leading us toward development permanent
