Hardwire Underwater Communications

Ocean Technology Systems

Many teams today choose to utilize hardwire communications ocean technology systems because they provide the safety of having divers tethered to the surface while maintaining clear and constant communication throughout their dive. In addition, hardwire systems tend to be less expensive and simpler than wireless units.

Underwater communication ocean technology systems convey a wide range of information, including navigation, sensor data, and video. They are essential for marine exploration, environmental monitoring, and collecting scientific data. Underwater communication networks are also used by military forces.

RF electromagnetic waves enable communication between offshore surface stations and onshore data centers, and between underwater nodes. However, turbid underwater environments make these signals susceptible to significant attenuation and multipath dispersion. Moreover, a lack of energy harvesting options restricts underwater wireless networks’ operational duration and reduces network reliability. Hence, alternative communication methods such as optical and acoustic underwater communication have gained popularity in recent years. These devices can transmit positional data and control autonomous underwater vehicles.

Diver Recall Systems

Ocean Technology Systems

This simple and effective one-shot device is used by dive support personnel on the surface to signal divers to surface or return to their vessel. It creates an acoustic pulse underwater to recall free-swimming divers by emitting 5 alarm signals (horn, siren, wail, yelp and phaser). The ocean technology systems is portable and comes standard with a high-quality hand-held microphone, transducer with 25′ of cable, rechargeable batteries, battery charger and main electronic unit.

The United States. The Navy likes it and so do people who dive for fun or to find treasure.. This diver recall/hydrophone system will alert all divers within range with voice, solid or intermittent tones and offers a listen mode to hear marine biological and man-made noise. It also has a line-in connection for feeding sound into the water (music, pre-recorded announcements) and a record-out receptacle for connecting to a recorder. This is a perfect solution for any scuba diving application.

Subsea Communication Systems

Ocean Technology Systems

A robust marine communication ocean technology systems is critical to enabling underwater collaborative operations. This enables real-time data transfer between unmanned robotic vehicles and human operators for seafloor mapping, territory inspection and maintenance, search and rescue, or infrastructure construction and repair.

Acoustic comm systems use acoustic signals that propagate at the speed of sound through water. However, multipath effects and turbulence interfere with the signal. Furthermore, the high power requirements of acoustic comms limit their deployment and use.

Optical communication uses EM waves, which travel significantly faster in water than acoustic waves. Moreover, optical transmitters and receivers can be located at a close distance, limiting the need for acoustic comms. In addition, EM waves can overcome the problems of acoustic comms with multiscattering and chromatic dispersion. Hence, optical communications have gained considerable interest as a broadband and safe complement to legacy acoustic underwater communication systems. Moreover, they can provide high bandwidth, low latency and bi-directional communication. They can also be used for submarine to surface communication.

Underwater Videography

Ocean Technology Systems

Capturing images or video underwater is a common hobby for many scuba divers, but it also has some serious applications. Scientists, for example, use underwater videos to observe the behavior of motile species such as butterfly fish or seals and to study phenomena such as underwater volcanic eruptions.

Videography equipment includes cameras that can be encased in waterproof housing, as well as lights and other accessories. Often, camera housings are sold separately from the cameras that go inside them.

Lighting is important for underwater videography because the water absorbs light as it moves through it, and this affects colors. For example, reds are filtered out at depth, so a diver who wants their footage to have vibrant color needs to add a flashlight or other light. Editing tools may include noise reduction and stabilization to smooth out shaky footage. A good underwater video also requires careful attention to composition. This is because viewers tend to look at underwater scenes from a down-facing perspective, so the camera should be positioned low enough to reflect this view.
