New Subsea Camera Boasts 4K UHD Image Quality

A new subsea camera from Sidus Solutions, the SS490, is a 4K UHD camera that provides superior video image quality at four times the resolution of 1080 full HD images. According to Sidus Solutions, the camera maintains full 4K resolution while providing excellent focus with a 20x zoom and a combined optical and digital zoom of 144x. The SS490 delivers better picture quality than non-4K models due to its use of HDR (high dynamic range). This is especially helpful with varying lighting conditions such as working with multiple ROVs or reflectivity from stainless steel objects. “We developed

How the right measurement technology can help Chile’s aquaculture industry fulfill its potential   Climate change is just one of the challenges that ports in Chile increasingly have to deal with, and an investment in the latest Doppler technology and online systems has proven to be a significant benefit for its ports. How can Chile’s aquaculture industry maximize this technology’s potential?    From the early 1990s to 2007, Chile’s aquaculture took off, and by 2006 it was producing 38 percent of the world’s salmon. Now, the country produces 1.4-1.

The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in a study by researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). Plastic bags, glass shards and fishing nets: despite its location, far from any urban areas, the amount of litter in the depths of the Arctic Ocean continues to rise, posing a serious threat to its fragile ecosystem. Since 2002, AWI researchers have been documenting the amount of litter at two stations of

All Hands on Deck: ROVs and AUVs Aid Search for Franklin

Marine and subsea unmanned vehicle technology is playing an increasingly greater role in underwater archaeology, including the search for the historic shipwreck Franklin.   For centuries, the ever-changing sea ice of the Northwest Passage made the route through the Arctic Ocean unpredictable and, on occasions, virtually impassable. Yet, since the 1500s the promise of connecting the Atlantic and Pacific Oceans, and the economic benefits which would follow, were enough to entice many expeditions into this treacherous pass. One such explorer, Sir John Franklin, set sail in 1845 from England with

Forum ROV to support University Renewables Projects

Forum Energy Technologies, Inc. won an order to supply the University of Limerick with a Remotely Operated Vehicle (ROV) to support its subsea inspection and intervention work on renewable energy infrastructure.   The University’s Mobile and Marine Robotics Research Centre (MMRRC) purchased the Sub-Atlantic Comanche 2,000m Observation Class ROV and associated launch and recovery system for delivery in March 2017 under a MaREI Science Foundation Ireland infrastructure grant (15/RI/3232).    The Comanche was selected due to its high thrust to drag ratio enabling it to operate in

Scientists Find Life at Unexplored Ocean Depths

With a brand new ROV in tow, a team of leading geologists, chemists and biologists recently returned to the largely unexplored Mariana Back-Arc to search for life at depths greater than 13,000 feet.   Led by Dr. David Butterfield, JISAO, University of Washington, and Dr. William Chadwick, NOAA-PMEL and Oregon State University, the group returned to the Back-Arc for the second phase of a two-part exploration of the region. In 2015, the team of scientists located new hydrothermal vents in the Back-Arc region, including evidence of recent lava flows. This year, the team returned to these vent
