The interactions between marine mammals an … The interactions between marine mammals and sonar have been a subject of debate since the invention of the technology. Active sonar, the transmission equipment used on some ships to assist with navigation, is detrimental to the health and livelihood of some marine animals. Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts their feeding and can cause mass strandings. Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey. It is conjectured that active sonar transmitters could confuse these animals and interfere with basic biological functions such as feeding and mating. The study has shown whales experience decompression sickness, a disease that forces nitrogen into gas bubbles in the tissues and is caused by rapid and prolonged surfacing. Although whales were originally thought to be immune to this disease, sonar has been implicated in causing behavioral changes that can lead to decompression sickness.s that can lead to decompression sickness.

Estudis recents han demostrat que els zífids i els rorquals blaus són sensibles al sonar actiu de freqüències mitjanes i s'allunyen ràpidament de la font del sonar, comportament que en pertorba l'alimentació i pot provocar encallaments en massa. Alguns animals marins, com ara les balenes i els dofins, fan servir l'ecolocalització («biosonar») per localitzar els depredadors i les preses. S'ha conjecturat que els transmissors de sonar actiu podrien confondre aquests animals i interferir amb funcions biològiques bàsiques com ara l'alimentació i l'aparellament. L'estudi ha demostrat que les balenes pateixen la síndrome de descompressió, un trastorn que provoca embolismes amb bombolles de nitrogen als teixits i passa quan els animals surten a la superfície de manera ràpida i prolongada. Tot i que anteriorment es considerava que les balenes eren immunes a aquest trastorn, el sonar s'ha relacionat amb canvis etològics que poden causar la síndrome de descompressió.poden causar la síndrome de descompressió.
