Marine research material
1. Ocean bottom seismometer
is a instrument is that design to to record the earth motion under oceans and lakes from man-made sources and natural sources. This is to sensor the seismic and acoustic events in the sea floor. It can be caused by the earth quake and also can be caused by the tremors as well by the artificial sources. analyzing the data information about the kind of source and, in case of natural seismic events, the geophysics and geology of the sea floor and the deeper crust. This instrument is place in the under water and this machine will detect all of the vibration in under water, and also this machine will know the source of the vibration.
2. ROV underwater
ROV is a remotely operated underwater vehicle, so basically this is machine is the vehicle that can run in under water but we don’t have to put human in it, all of it is already controlled by remote. Because the ocean is so deep, so human can’t resist the pressure down there. So with this machine we can do dive into deep ocean without go down we just controlled this thing to down there and observe from the ground.
Conventional R.O.V.s are built with a large flotation pack on top of an aluminium chassis, to provide the machine to float to the ground. Syntactic foam is often used for the flotation. A tool may be fitted at the bottom of the system and can accommodate a variety of sensors. By placing the light components on the top and the heavy components on the bottom, the overall system has a large separation between the center of floating system and the center of gravity (this provides stability and the stiffness to do work underwater) and also in this rov is placed the camera to us to see what’s happened down there.
