When it comes to natural video presentations of marine ecosystems, sound is an important component. This is often accomplished through use of a hydrophone, or a microphone designed for underwater use. One important consideration is depth. Those who set out to capture sound near the surface sometimes simply covering normal microphones with thin plastic, such as a balloon. For deeper recordings, there are a number of specialized brands, such as the Aquarian H2a. One thing to be aware of is that hydrophones are extremely sensitive to touch. If the hydrophone is connected to a recording device, it has the potential to overload input, damaging internal circuitry. You should also take care not to bump or jostle it. Another important consideration is that hydrophones tend not to have a flat response curve when it comes to detecting frequencies of sound. This reflects the much greater variety of high-frequency sounds underwater (compared to terrestrial environments), which necessitates a limiting of high-end input. When setting up a hydrophone, it is important to carefully scout your location. If you are recording in an area with frequent motorized vessel traffic, such as a popular cove, diving spot, or shipping lane, there may be frequent interruptions to the clear, distortion-free underwater sound you are after.
