Seismology is the scientific discipline of studying earthquakes and seismic elastic waves that travel through and around the Earth. It studies a broad field of work that ranges from exploratory seismology, such as the search for underground deposits of oil, gas and minerals, to earthquake prediction and analysis of the composition and physical properties of the Earth's interior. Marine seismology or marine seismographic acquisition is the process of collecting information and creating an image of the seabed (2D, 3D) with the help of sound waves. With the advancement of technology, modern ships are equipped with a set of complex seismic equipment, the purpose of which is to explore the sea and find hydrocarbon reserves for the oil and gas industry. Such vessels are called seismic vessels. Due to their ability to generate very loud sounds during operation (up to 240 dB), these ships have to follow special guidelines and thus require special care and attention during system operation. These loud noises pose a danger to both humans and sensitive marine animals. This thesis will attempt to investigate, analyze and explain the problems associated with seismic imaging and surveying and provide appropriate solutions and advice on what to do to minimize their impact.
