health and conservation by the public. There’s an increased awareness about the dependence of our security and our economy on the oceans. People simply care a lot more (today).• A growing awareness of the necessity for sustainable use of our oceans, which includes everything from fisheries, to marine transportation, to critical minerals and pharmaceuticals. Using that same time frame, put in perspective the evolution of unmanned maritime systems as you see it.To start, just this week we’ve decided we are going to move from the word ‘unmanned’ to ‘uncrewed.’

As ROV SuBastian makes its way up the slopes of the seamounts and canyons the team has been exploring this expedition, the changes in light, temperature, pressure, and other environmental factors are remarkable. From the dark and cold soft sediments of the plateau floor to exposed rocky escarpments, fields of mesophotic black corals, and eventually the well-lit realms of the upper slopes and reef crest - these changes lead to a whole gradient of habitats suitable in different ways for many diffe

Offshore Wind Could Bring In $1.7B to U.S. Treasury by 2022

The United States has an opportunity to accelerate offshore wind energy growth, and benefit from 28 new gigawatts of wind power and $1.7 billion in U.S. Treasury revenue by 2022, according to a study released by the energy intelligence group Wood Mackenzie. Apart from the benefits to the Treasury, the offshore wind industry in the U.S. could create 80,000 jobs annually from 2025 to 2035.Commissioned by four energy industry groups, American Wind Energy Association (AWEA), National Ocean Industries Association (NOIA), New York Offshore Wind Alliance (NYOWA), and the Special Initiative on Offshore

Scientists Discover First Methane Seep in Antarctic Sea Floor

Scientists have discovered an active methane seep from Antarctica's sea bed that could shed light on the potent greenhouse gas trapped beneath the frozen continent.Marine ecologist Andrew Thurber first glimpsed what a colleague described as a "microbial waterfall" during a dive in the icy waters of the Ross Sea in 2012. What looked like a superhighway of white patches on the ocean floor were clusters of tiny organisms drawn to the methane leak."My first thought was 'wow,' and I was immediately enamored with what this means for science," said Thurber, an assistant

Mediterranean Marine Life Flourishes During Lockdown

Marine life in the Mediterranean off Italy flourished during the coronavirus lockdown as water quality improved and species moved into spaces vacated by people and ships, the Italian coastguard has found.The strict rules halting business and movement for two months offered an unprecedented opportunity to monitor the impact of human activity on the sea that surrounds Italy.Since April, the coastguard has used water samples, underwater footage filmed by remotely operated vehicles and its own divers, and a census of unusual sightings of marine species close to heavily populated areas to monitor the sea.

A recent paper by Monterey Bay Aquarium Research Institute (MBARI) has revealed almost 600 hydrothermal chimneys around the Endeavour Segment of the Juan de Fuca Ridge, about 350 kilometres (220 miles) northwest of Washington State. The vents, located in a valley about 14 kilometres (8.6 miles) long and 1.5 kilometres (0.9 miles) wide, has been studied previously, but never mapped until now because of difficult access.Hydrothermal vents are created by magma beneath the seafloor that heats water within the surrounding bedrock, emerging from the seafloor in the form of underwater seeps and geysers.

experiments, unexploded ordinance, location of drowning victims, and missing evidence recovery. The tools we provide to the operators undertaking these tasks vary from metal detectors and sonar systems to Remote Operated Vehicles (ROVs).According to The Remotely Operated Vehicle Committee of the Marine Technology Society, “exactly who to credit with developing the first ROV will probably remain clouded, however, there are two who deserve credit. The PUV (Programmed Underwater Vehicle) was a torpedo developed by Luppis-Whitehead Automobile in Austria in 1864, however, the first tethered ROV

#Oi2020 History

The 1980s (and into the 1990s) brought about advancements within submersibles used for scientific deep water research. According to the book Advances in Marine Technology, it was marine engineer and submarine Graham Hawkes, who “was recognized for designing approximately 70% of the manned submersibles” manufactured during that time. The book, as published by the Marine Technology Society, also notes that one of Hawkes’ inventions was “the Deep Rover, a battery-powered one-person acrylic bubble submersible equipped with robotic arms strong enough to handle construction yet

, specifically a higher level of appreciation of technologies such as acoustics and sensors. This also included manned submersibles, which at the time, “were believed to be the answer to deep underwater exploration, taking humans beyond safe diver depth,” according to the book Advances in Marine Technology, as published by the Marine Technology Society. In fact, as this technology was developing, it was also concurrently “pushed to the sidelines by the development of ROVs, which proved the safest way to work at deep depths, marking the transition from human intervention to robotics
