In this paper, the main maritime exploration techniques have been analyzed, the seismic refraction, and the seismic reflection. Pursuant to the performed research, we considered the seismic reflection to be of interest, for which we shall suggest improvement in how the data is collected by proposing a hydrophone design. At present, the continuation of exploitation of the traditional basins of natural resources (gas, oil), as well as the emergence of new reserves, such as those in the Black Sea, make it compulsory ...

This paper presents an electro-acoustic instrument, used in geophysical (seismic) prospecting, for the reception of sound waves, namely the geophone. The geophone is a transducer which transforms the displacement of the soil particles into electrical signals. The article aims at presenting the functioning of a standard electromagnetic geophone and of the newer geophone models, built using the MEMS (micro-electro mechanical systems) technology. Below, a scheme for amplifying the original signal generated by a SM-24...

In this article, we will present the types of seismic waves, how their collection is performed and their preparation for analysis and processing. Understanding these aspects can help improve in future any stage of the process, by using new hardware and/or software equipment, in continuous development around the world. There are three steps in seismic exploration of the ground. The first one is seismic data acquisition which is done in a specific location, ground or water, using a seismic source. The seismic wave g...
