FORCE identify the best sensor settings and operating schedule for future data collection at the FORCE demonstration site.   Dr. Haley Viehman, a post-doctoral fellow at Acadia University, will be analyzing the data upon retrieval. This work builds on her previous research at the University of Maine, where she studied fish interactions with an in-stream tidal turbine deployed in Cobscook Bay.   “I’ll be examining how fish use the water column, and how their densities and depths vary with respect to time of day, tidal stage, and current speed,” said Dr. Viehman. &ldquo

Deaths of North Atlantic Right Whales Puzzle Scientists

backhoe to get inside the animals to perform necropsies.   The whales, designated a species at risk, have been sighted in the Gulf of St. Lawrence in higher-than-normal numbers this summer, Davies said, possibly because their zooplankton food source is scarcer in other habitats such as the Gulf of Maine and the Bay of Fundy.   Canada's Department of Fisheries and Oceans closed some snow crab fisheries early in response to the deaths, and has asked ships in the high-traffic Gulf of St. Lawrence to voluntarily keep their speed to 10 knots or less.   But longer-term solutions such as

Maine Marine Earns Grant to Study Ocean Turbine Stress Limits

Maine Marine Composites has been awarded a $249,976 federal grant from the Bureau of Safety and Environmental Enforcement (BSEE) to analyze the best ways to predict fatigue in the support structures of floating offshore wind turbines. A federal agency, the BSEE was created in the wake of the Deepwater Horizon disaster in the Gulf of Mexico to promote safety, protect the environment and conserve resources in the exploration and development of the Outer Continental Shelf. "Maine Marine Composites engineers predict the performance and stress on components in ocean-based systems by analyzing

Floating Offshore Wind Turbine Design Passes ABS Review

The American Bureau of Shipping (ABS) has completed the design review of the Front End Engineering and Design (FEED) documentation for the VolturnUS, a floating offshore wind turbine (FOWT), developed by the University of Maine Advanced Structures and Composites Center.   “UMaine is pleased that its innovative design became the first floating wind turbine concrete semisubmersible hull to be reviewed by ABS, and found to meet the ABS requirements,” said Dr. Habib J. Dagher, P.E, UMaine Composites Center executive director and principal investigator.    “After 10

Penobscot Bay Survey in Focus at NOAA Stakeholder Meetings

Recently, NOAA’s Office of Coast Survey hosted two stakeholder events in Belfast, Maine, to engage the local community on various NOAA products and updates in the region. Originally from Belfast himself, Rear Adm. Smith, director of the Office of Coast Survey, provided a warm introduction to both events. Dean Moyles, of Fugro, a NOAA hydrographic contractor, presented a summary of the hydrographic survey work being performed in Penobscot Bay. Lt. David Vejar, NOAA northeast navigation manager, highlighted various products and services, including how to access NOAA charts and data, the upcoming

Scientists think that American eels spawn somewhere in the southwest corner of the Sargasso Sea, which is surrounded by circulating ocean currents. The eels migrate as tiny larvae to fresh waters along the coast, where they spend their adult lives. Where the adults spawn and how the larvae migrate to the coast both remain mysteries.

A Slithery Ocean Mystery

Scientists gain grasp on the epic migration of eels   One sentence in a New York Times article caught Larry Pratt’s eye and set the scientific investigation in motion.   The story was about fishermen harvesting juvenile eels in coastal waters of the Gulf of Maine and selling them for more than $2,500 a pound, mostly for unagi in Asian fish markets. The eels, the article claimed, “are believed to spawn in the Sargasso Sea and drift on currents to Maine, where they make their way to fresh water.”   “It seemed far-fetched,” Pratt said.   Pratt

The performance of the device will be demonstrated and validated during a year-long deployment proposed to occur off the coast of Oregon. Ocean Renewable Power Company of Portland, Maine, will enhance the performance of its tidal turbine system by integrating several advanced component technologies. The device's novel floating design will move the turbine near the surface to capture higher flow velocities and will help reduce the cost of installation and on-water operations, ultimately

After Florida, more States Press US for Offshore Drilling Exemptions

the Interior Department granted Florida's request to opt out.   The backlash could complicate President Donald Trump's efforts to expand oil and gas production offshore. A proposed leasing plan unveiled last week aims to open up all U.S. coasts to drillers over the next five years. Alaska and Maine are the only two U.S. states whose governors have expressed support for the plan.   The governors of Delaware, North Carolina, and South Carolina on Tuesday were seeking meetings with Interior Secretary Ryan Zinke to press their case that drilling would pose significant risks to coastal tourism

The Meygen tidal stream energy project is currently under construction off the coast of Scotland. By the early 2020s, MeyGen Limited intends to deploy up to 398MW of offshore tidal stream turbines to supply clean and renewable electricity to the U.K. National Grid.

since 2014. He succeeds retiring Regional Administrator John Bullard who had been in the position since 2012.   Pentony will head the agency’s regional office, which has responsibility for managing approximately 100,000 square miles of the Northwest Atlantic, the large marine ecosystem from Maine to Cape Hatteras and the Great Lakes. As Administrator, he will also oversee aspects of international fisheries conservation and management in the region.   Before joining NOAA Fisheries in 2002, Pentony worked for five years as a policy analyst for the New England Fishery Management Council

South Carolina's Republican Governor Henry McMaster asked Zinke for an exemption, citing the value of his state's coastal tourist economy.   Maine Governor Paul LePage and Alaska Governor Bill Walker are the only coastal state governors who support the expansion of offshore drilling, with many of the rest seeking exemptions in the wake of the Florida decision.   Zinke's abrupt announcement on Florida also took industry groups by surprise

Launching the Jamie Hanna

On August 14, 2012, more than 50 fellow lobsterman, boat workers, mechanics, family, and friends gathered to witness the launching of the 55-foot research and lobster vessel Jamie Hanna. A procession of cars made the 2 mile trip to the launching ramp at Outward Bound on Clarke Island, Maine. The lead car cleared the road to make way, as the 20 ton hydraulic trailer inched along and a crew on the pilothouse roof lifted phone lines and branches. When the boat arrived at the ramp an hour later, the tide was falling and concerns were raised about whether the boat would fit between the rocks and the

; The 155-foot-long, 60-foot-high and 60-foot-wide module was lifted to a height of approximately 100 feet using four cranes:  two of Bath Iron Works’ 300-ton capacity cranes and two additional 400-ton cranes provided by Reed & Reed, Inc., a construction company headquartered in Woolwich, Maine.  Once at the prescribed height, the ship’s 610-foot hull was then moved into position beneath the suspended module using the shipyard’s electro-hydraulic ship transfer system.  After confirming final positioning of the deckhouse and ship, the module was lowered into place.

US Awards $3.7 Mln for Wind Project off Maine

The Maine Aqua Ventus project, an experimental floating deep-water offshore wind project off the coast of Castine, Maine, has received $3.7 million from the U.S. Department of Energy.   The project was originally competing for a $47 million grant but was passed over for projects in New Jersey, Virginia and Oregon. The DOE instead awarded Maine $3.7 million for work to continue on a pilot project off the coast of Monhegan.
