How Will the Fukushima Water Release Impact the Pacific Ocean?
;s recommended limit of 10,000Bq per litre for drinking water.Why is it acceptable to release tritium into the ocean?One surprising thing about radiation is how common it is. Almost everything is radioactive to some degree, including air, water, plants, basements and granite benchtops. Even a long-haul airline flight supplies a few chest X-rays worth of radiation to everyone on board.In the case of tritium, natural processes in the atmosphere generate 50-70 peta-becquerels (PBq) of tritium every year. This number is difficult to grasp, so it’s helpful to think of it as grams of pure tritium. Using
Efficient Wave-Generated Power … Really!

i-Tech Services Adds Mini ROV Capability
offering. Furthermore, it provides clients with a reliable, cost-effective and safe alternative to traditional manned inspection or work-class ROV services.”A cost-effective solution for smaller work scopes, the mini ROVs are quick to deploy and can be transported easily to site via helicopter or airline carrier for faster transportation.Despite their compact size, the mini ROVs have high maneuverability and power-to-weight ratio allowing them to carry small tools and manipulators for operating effectively in strong currents, i-Tech Services said. They are well suited for rapid mobilization and
Scientists Study Largest Underwater Volcanic Eruption
In July 2012, airline passengers flying over the Southwest Pacific Ocean spotted a large and unusual object floating on the water’s surface. That object, which turned out to be a giant raft of pumice, was evidence that an underwater volcanic eruption had occurred. And as the raft continued to grow to roughly the size of Philadelphia, scientists observed that the eruption was extraordinarily large. The eruption had occurred at the Havre volcano northeast of New Zealand, and was the largest to take place underwater in the past century. “We knew it was a
US Firm Gets Go-ahead to Resume MH370 Search
Malaysia will allow a U.S.-based exploration firm to resume the search for Malaysia Airlines flight MH370, an airline support group told families of the victims on Friday, in a bid to solve one of the world’s greatest aviation mysteries. Flight MH370, carrying 239 people, disappeared en route from Kuala Lumpur to Beijing in March 2014. Australia, China and Malaysia ended a fruitless search in January last year. An email, sent from the MH Family Support Centre and seen by Reuters, said the government had accepted an offer by the company, Ocean Infinity, to resume the search on a “no
Malaysia Confirms Debris is from Missing MH370
Malaysia confirmed early on Thursday that a piece of a wing washed up on an Indian Ocean island beach last week was from Malaysian Airlines flight MH370, the first trace of the plane found since it vanished last year with 239 people on board. "Today, 515 days since the plane disappeared, it is with a heavy heart that I must tell you that an international team of experts have conclusively confirmed that the aircraft debris found on Reunion Island is indeed from MH370," Prime Minister Najib Razak said in an early morning televised address. "I would like to assure all
Drydocks World Completes World’s Largest Turret
and offshore services to the shipping, oil, gas and energy sectors marked a major milestone in successfully completing the world’s largest turret mooring system with His Highness Sheikh Ahmed bin Saeed Al Maktoum, President, Dubai Civil Aviation Authority and Chairman and Chief Executive, Emirates Airline and Group attending the sail-away and completion ceremony to celebrate the occasion. At almost 100 meters high, weighing over 11,000 tons and with a diameter of 26 meters, the turret will ensure the Prelude floating liquefied natural gas (FLNG) facility can operate safely in the most extreme
ESS Buoyancy Solutions for Bluefin Robotics AUVs
Engineered Syntactic Systems (ESS), a global supplier of syntactic solutions, provides syntactic buoyancy for Bluefin Robotics Autonomous Underwater Vehicles (AUVs), including the 4,500 meter Atremis 21 used in the ongoing search for missing Malaysian Airline’s Flight 370. The Bluefin 21 was designed for extended remote operations in the hostile conditions of the deep sea. At 21 inches in diameter, space for uplift (buoyancy) is limited, but critical. ESS said it worked closely with Bluefin to engineer a buoyancy solution that would meet their design specifications, providing a syntactic
Ebola Fears Hit the Maritime Market
entry procedures for ships that have sailed from West Africa in a bid to control the potential spread of the deadly Ebola virus. Ebola has killed more than 3,400 people in Guinea, Sierra Leone and Liberia, and its spread has become a global concern -- with worries for trade, which could affect the airline and tourism industries together with seaborne activity. The virus is already threatening to disrupt logistics activity in West Africa and has already rattled commodities and mining markets as the region is a major source of raw materials such as iron ore as well as crude oil, bauxite and cocoa
