Preserving The Past: 4K Imaging Shines Light On SubSea Historical Artifacts
In March 2022, subsea explorers made a profound discovery at a depth of 3,008 m (9,869 ft) below the surface of the Weddell Sea’s icy Antarctic waters. The Endurance22 Expedition, supported by the Falklands Maritime Heritage Trust, located the wreck of the Endurance, a wooden ship that sank off the coast of Antarctica in 1915 after getting trapped in the pack ice.
Advancements in Subsea High Definition Imaging
This article discusses how these philosophies are applied to our development of High Definition imaging systems, including FleXlink technology.
LEDs are Now the Choice for Underwater Lights
Properly designed underwater LED lights can be “plug & play” replacements for halogen lights.
Color Purity of LEDs
The term “Color Purity” often invites inquiries from customers viewing the spectral graphs generated by our integrating sphere. Color Purity was specifically created for LEDs with the 1997 CIE 127 Document and does not apply to any other type of light source, such as HID, HMI, CFL, or incandescent.
Recent Advances in Deep Sea LEDs for the Offshore Industry
Manned vehicles, ROVs, and Saturation Divers are adopting Light Emitting Diodes (LEDs) as powerful and durable light sources. Developments continue to follow the rapid evolution of LEDs for general topside illumination. Our engineers have devised compact ocean optics, both reflectors and lenses. Successful pressure compensation of both LEDs and driver electronics foretell future designs in diver and vehicle lighting.
Displacing Darkness: Lights in the Deep Sea
Our line of underwater lights are used around the world by the most demanding end users in the earth's most extreme environments, including hot water hydrothermal vents, high pressure ocean trenches, radioactive nuclear storage facilities, and biohazardous sewage treatment plants.
True Lumens Report: Accurate Lighting Data Guaranteed
We ship a True Lumens Report with our SeaLite Sphere, Lumos, and Nano lights. You can count on the lumens output and emitted color matching our design specifications for every unit.
Subsea High-Definition Video Systems
A technical discussion of the challenges and solutions for High Definition (HD) video systems in subsea applications contrasted against traditional analog technology.
Diode Lasers in Underwater Applications
Diode lasers are particularly well suited to marine applications because of their insensitivity to vibration, long life, compact size, wide input voltage, and instant restrike.
Advanced Underwater LED Power Supply and Light Control
While great attention is given to LED solid state devices during their rapid evolution, they are just one component in a larger electronic circuit.
Underwater Light Reflector Design
Two of the most important performance parameters for underwater lights are beam control and beam angle, both of which are primarily functions of reflector design rather than lamp type.
Optimal Lighting Geometry for Underwater Lights and Cameras
Following ideal reflector design, the placement of an underwater light, or "luminaire", relative to the camera will have the greatest affect on image quality, due to "Common Volume Scattering," which can result in backscatter in the present of suspended particles or organisms.
Products In Use
The Future of Subsea Imaging is a Vision of Collaboration
Collaborating on the Future of 4K Subsea Imaging In 2018, scientists and engineers at the Monterey Bay Aquarium Research Institute (MBARI) began researching upgrades to their high-definition camera systems on the 1,800-meter ROV Ventana and the 4,000-meter ROV Doc Ricketts.
DVS-300 Invades Normandy
Our diver video system, DVS-300, assisted in creating the largest and most precise archaeological map of the five invaded beaches in Normandy to commemorate the 70th anniversary of D-Day.
New Discoveries in Lake Baikal by the MIR Submersibles
The MIRs have provided stable light and camera platforms for the making of well known deep ocean films, including James Cameron’s Titanic, Bismarck, Ghost of the Abyss, IMAX Titanica, Al Giddings’ Treasure of the Deep, and BBC’s Blue Planet.
DeepSea Supplies Ceramic Flotation for HROV Nereus Project
The Nereus was a hybrid ROV built by the Deep Submergence Lab at WHOI to design the deepest parts of the ocean. We designed and manufactured ceramic floatation for the project.
The Edison Towers
Our SeaBatteries and HMI Lights were used to illuminate the Titanic for a live video feed to two cruise ships that were part of a 1996 expedition.
HMI Light with Alvin Featured at Smithsonian Museum
The Smithsonian National Museum of Natural History features an image of Alvin’s manipulator arms with our HMI SeaArc® lights attached.
Lens Field Calculator
Our lens field calculator is a complimentary web-based design tool for calculating video camera lens field of views in air and in seawater.
Under Pressure™ Design Software
Under Pressure is a downloadable PC program that enables quick, accurate designs of pressure housing and pressure vessels.
Under Pressure: Testing Before Deployment is Integral to Success at Sea
Pressure testing has a long and storied history and remains one of the most useful tools subsea designers have available. It is a critical part of preparation but can be one of the first steps cut when resources get stretched.
