Nutrient Pollution is Widespread in US Lakes -EPA

A recent study has found that nutrient pollution is widespread in the U.S. lakes, with four in 10 lakes suffering from too much nitrogen and phosphorus, according to national assessment conducted by the U.S. Environmental Protection Agency (EPA).   Excess nutrients can cause algae blooms, lower oxygen levels, degraded habitat for fish and other life, and lower water quality for recreation. The National Lakes Assessment also found an algal toxin – microcystin – in 39 percent of lakes but below levels of concern. Low concentrations of the herbicide atrazine were found in 30 percent of

US Offshore Wind Faces Pushback from Fishing Groups

a petition to delay the auction was presented to the federal court. The U.S Bureau of Ocean Energy and Management (BOEM) requires an extensive stakeholder marine spatial planning process that de-conflicts the wind energy area prior to the Point of Sale Notice (PSN).  The Business Network for Offshore Wind, a business network that aims to help usher the U.S. into the offshore wind market, said it believes addressing stakeholder conflicts throughout the offshore wind development process is critical. The Network and its members say they are committed to meeting all local, state and federal environmental

Engineers Expand the Window for Installing Monopiles

with Rampion and its contractors, has developed an  analysis and modeling process to fully understand why large monopiles oscillate in relatively small wave heights; and to increase the operating window for their installation. Monopiles and turbines are increasing in size as wind farms move farther offshore.    At the Rampion Offshore Wind Farm, which is currently under construction off the south coast of the U.K., the developer was concerned that these large structures were beginning to oscillate in relatively small wave heights. This was affecting the operational window for lowering them

Copenhagen Subsea: New Milestone for Thruster Reliability

Copenhagen Subsea A/S is introducing a new standard for testing subsea thrusters    The new standard for testing subsea thrusters implemented by Copenhagen Subsea A/S dictates a remarkable 1,000 working hours of continuous operation at maximum power. Once tested and validated, the thruster must still maintain full functionality and unaffected performance.   When operating in open water, the cost of a failing subsea thruster is critical. Every malfunction, delay or maintenance-break related to the subsea exploration vessel will set back the entire operation. Imagine for a moment this

Gazprom: Work on Underwater Section of Turkstream to Begin in H2 2017

Work on the underwater section of the Turkish Stream pipeline will get underway in the second half of next year, Alexei Miller, chief executive of Russian gas giant Gazprom, told journalists on Tuesday. Miller also said that both lines of the underwater section, one that will ship gas to the Turkish market and a second with gas destined eventually for Europe, will come on stream by the end of 2019. Where that gas from the second line will come ashore in Europe has yet to be finally determined. Gazprom, Italian energy firm Edison and Greek gas retailer DEPA in February signed a memorandum of

Airborne Hydrographic Survey Commissioned After NZ Earthquake

Fugro’s LADS technology is being deployed in New Zealand to assist in relief efforts following the damaging 7.9 magnitude earthquake near Christchurch on November 14, 2016. At the request of the New Zealand Government, the Royal Australian Navy (RAN) Laser Airborne Depth Sounder (LADS) Flight is to conduct a rapid hydrographic survey of the seafloor in the coastal margins of the north east coast of the South Island.   RAN LADS commanding officer, Flight Lieutenant Commander Susanna Hung, explained the mission. “We will fly over the area and collect hydrographic survey data, which

Boeing and Liquid Robotics have collaborated on extensive integration on the Sensor Hosting Autonomous Remote Craft (SHARC), a version of the Wave Glider, since 2014.

Offshore Deepwater Rebound?

round is Mexico’s first ever tender for deepwater exploration acreage.   “Mexico’s opening presents the industry with great opportunities, so we are pleased to secure an early position. The award grants Statoil access to significant frontier acreage in an underexplored part of offshore Mexico. The blocks are virtually untested, with considerable subsurface uncertainty, but with play-opening potential”, says Tore Løseth, Statoil’s vice president for exploration in the US and Mexico.   The winning bids for both blocks consisted of an additional royalty

Explosives Cleared from Baltic Sea Wind Farm Site

Remaining munitions from World War I, World War II and the Cold War have been removed from the site of the future Arkona offshore wind farm in the German Baltic Sea, allowing installations to begin securely in 2017 as planned.   The construction site, with an area of 39 square kilometers halfway between the island of Rügen and the Danish island of Bornholm, is now completely free of explosive ordnance, E.ON announced.    The operation to clear the site of explosives took four months in all and started with an examination of the seabed.

Polar Sea Ice the Size of India Vanishes in Record Heat

Sea ice off Antarctica and in the Arctic is at record lows for this time of year after declining by twice the size of Alaska in a sign of rising global temperatures, climate scientists say.   Against a trend of global warming and a steady retreat of ice at earth's northern tip, ice floating on the Southern Ocean off Antarctica has tended to expand in recent years.   But now it is shrinking at both ends of the planet, a development alarming scientists and to which a build-up of man-made greenhouse gases, an El Nino weather event that this year unlocked heat from the Pacific Ocean and
