to the 2012-built Brave Tern are necessary because wind turbines became heavier and the blades of the rotor blades have grown larger. Sister vessel Bold Tern will get the same upgrade later this year.   Brave Tern will first do a maintenance job in the North Sea, before heading to the U.S. east coast where it will assist in the construction of the first U.S. offshore wind farm.

NOAA Proposal Aims to Extend Reduced Whale Ship Strikes

currently scheduled to expire in December 2013. NOAA's proposal to make them permanent, which includes a 60-day public comment period, was filed at the Federal Register today. The existing rules, which reduce an ocean-going vessel's speed to 10 knots or less during certain times and locations along the East Coast from Maine to Florida, have reduced the number of whales struck by ships since 2008, when the speed limits began. No right whale ship strike deaths have occurred in Seasonal Management Areas since the rule went into place. Modeling studies indicate the measures have reduced the probability of

Oyster, Clam Farms Face Blow from Acidification

U.S. shellfish producers in the Northeast and the Gulf of Mexico will be most vulnerable to an acidification of the oceans linked to climate change that makes it harder for clams and oysters to build shells, a study said on Monday.   The report said the two regions would be more at risk in coming decades than the Pacific Northwest, which had previously suffered the most from the problem, with losses to the oyster industry estimated at $110 million, putting 3,200 jobs at risk.   Carbon dioxide, emitted into the atmosphere by mankind's burning of fossil fuels, gets absorbed by the oceans

Bubbling Methane Vents Discovered Off US E. Coast

Mississippi State University (MSU) researchers say they have found more than 500 bubbling methane vents on the seafloor off the US east coast. Lead author Adam Skarke, assistant professor of geosciences at Mississippi State University (MSU) worked with researchers from the U.S. Geological Survey (USGS) and other institutions on a scientific team that discovered methane seeps in unlikely places along the seafloor on the northern part of the U.S. Atlantic margin. Before he joined the faculty at MSU, Skarke worked as a physical scientist at the National Oceanic and Atmospheric Administration's (NOAA)

Scientists Link Climate Change and Gray Snapper

Models Project Northward Distribution Shifts Using Temperature, Estuarine Habitats as Key Factors.   NOAA scientists continue to develop and improve the approaches used to understand the effect of climate change on marine fisheries along the U.S. east coast. Their latest study projects that one common coastal species found in the southeast U.S., gray snapper, will shift northwards in response to warming coastal waters. In a study published online December 20 in the journal PLOS ONE, researchers from the Northeast Fisheries Science Center (NEFSC) and the University of North Florida developed

Rising Seas to Displace Millions if Warming Unchecked

Antarctica and other regions will melt as global temperatures increase, leading to major rises in sea levels.   "I would avoid buying property in South Florida in particular," Strauss told the Thomson Reuters Foundation.   Coastal California, New York and other cities on the U.S. east coast would also be hit hard by rising seas if carbon emissions are not cut drastically, he said.   To substantially blunt the threat, emissions reductions would have to be bigger than those pledged by the United States and more than 145 other countries as part of a new U.N. deal to tackle

will now further examine the data to determine the relationships between the shape and composition of the seafloor and what lives there. This information can then be used to better manage this unique environment. Marine geoscientist Dr. Alix Post participated in a voyage to the Sabrina Coast region of East Antarctica on board the RV Investigator. The voyage, led by Macquarie University, completed the most extensive hydrographic survey in East Antarctica to date and collected long sediment cores that contain a rich archive of climate information. In addition, the survey completed detailed assessments

Delivery of the first ship, which will be operated by Oregon State University, is expected in fall of 2020.   Additional ships would likely be designated for the U.S. East Coast and the Gulf of Mexico, if funded by NSF with congressional appropriations and approval by the president. NSF would competitively select operators for those vessels, possibly in 2018.   Although similar in size, the new ships will differ greatly from R/V Oceanus, built in 1975 and operated

New Study Examines Hurricane Intensity; Pollution Transport

Gulf of Mexico, it may interact with an upwelling of cooler waters from the deeper ocean or, in the case of Isaac, a downwelling inside rings of warm water that separated from a warm-water current, called the Loop Current, that moves through the Gulf of Mexico to join with the Gulf Stream along the U.S. East Coast. As the storm moves forward, ocean temperatures are fueling the storm’s intensity.
