An Unintentional Iron Fertilization Experiment
beyond 42 north, but we expect that impacts would reach up to Alaska.”There are likely key areas of anthropogenic iron release in South America and Southern Africa that will grow over time, he says. It’s also likely that there were significant emissions during industrialization of the US east coast and throughout western Europe that would have added iron to the North Atlantic. These would have been most intense during the 20th century, and the impacts on the Atlantic resulting from this have probably come and gone.“Our results indicate that a widespread unintentional iron fertilization
NOAA Predicts Cooler Deep Waters for Gulf of Maine
The Gulf of Maine, historically one of the fastest-warming ocean regions in the world, is predicted to experience cooler bottom water temperatures this spring and summer, according to a new experimental outlook developed by NOAA scientists.Initial signs of this shift were reported by NOAA’s Northeast Fisheries Science Center and documented in the NOAA Fisheries 2025 New England State of the Ecosystem Report.Data shows that since late 2023, the Northwest Atlantic has seen cooler bottom-water temperatures due to the southward movement of the eastern portion of the Gulf Stream and possibly an increased
TDI-Brooks Concludes Geotechnical Campaign Off Turkey
TDI-Brooks, a U.S.-based marine services company specializing in geotechnical and offshore survey projects, has completed its fifth geotechnical investigation for DenAr Ocean Engineering in Black SeaThe RV NAUTILUS was dispatched to the Black Sea from the US East Coast to facilitate this operation. The geotechnical aspect of the investigation included 49 gCPTs, 50 JPCs, 48 CPTs, and 41 BCs.Additionally, an environmental component was incorporated, which comprised 27 Environmental BCs, 28 CTDs, 19 water samples, and 180 kilometers of marine fauna transects.TDI-Brooks provides a comprehensive range of
Maine Wins Federal Floating Wind Research Lease
The Biden administration on Monday issued an offshore wind lease to the state of Maine for a small project that will demonstrate floating turbine technology off the U.S. East Coast.The lease area covers 9,700 acres (3,920 hectares) and is 28 nautical miles (52 kilometers) from shore, an area that could accommodate up to 12 floating offshore wind turbines that could generate about 144 megawatts of electricity.Floating wind is widely acknowleded as the future of offshore wind, as it is able to tap stronger winds further from shore. It opens opportunities, too, for companies serving the offshore oil and
University of North Carolina Wilmington Orders Research Vessel from All American Marine
research vessel for the University of North Carolina Wilmington (UNCW). The vessel will operate as a multipurpose research platform capable of conducting a wide range of scientific missions, including oceanographic surveys, biological studies and educational outreach programs along the Mid-Atlantic, U.S. East Coast and offshore waters.The 73’ x 26.7’ aluminum catamaran, designed by Teknicraft Design in Auckland, New Zealand, incorporates a hydrofoil-assisted hull, ensuring reduced drag, enhanced fuel efficiency and passenger comfort. This dynamic hull design is optimized for stability and performanc
Underwater Power Grids Could Revolutionize How the US East Coast Gets Its Electricity
Offshore winds have the potential to supply coastlines with massive, consistent flows of clean electricity. One study estimates wind farms just offshore could meet 11 times the projected global electricity demand in 2040.In the U.S., the East Coast is an ideal location to capture this power, but there’s a problem: getting electricity from ocean wind farms to the cities and towns that need it.While everyone wants reliable electricity in their homes and businesses, few support the construction of the transmission lines necessary to get it there. This has always been a problem, both in the U.S.
Fugro Nets Fresh Work for Community Offshore Wind on US East Coast
Community Offshore Wind, a joint venture between RWE and National Grid Ventures, has selected Fugro to perform a geotechnical investigation of their lease area in the New York Bight.With 3 GW of offshore wind energy potential, the developed lease area could power more than one million homes in the region, making a valuable contribution to the US energy transition.The geotechnical work follows a successful site characterization program completed by Fugro in 2023.Covering the entire 510 km2 lease area and potential export cable corridors, the effort produced a preliminary earth model detailing geophysical
TDI-Brooks' New Vessel Ready for Work
TDI-Brooks' newest vessel R/V Nautilus (formerly known as Nautical Geo) is ready to go to work following a 6-month retrofit period in Las Palmas.The DP2 vessel is currently enroute to the U.S. East Coast to provide support for offshore wind operations. It is expected to be fully prepared for the first offshore wind program by early March.Built in 2000, the 75-meter-long vessel is equipped with the newly-acquired Geomiil Manta-200 CPT, which can be deployed through the mid-ship moonpool. The system has the capability to penetrate the soil up to 40-50 meters, depending on its composition.Nautilus
World's Largest Known Deep-sea Coral Reef Habitat Found
Covering 6.4 million acres, an area larger than Vermont, an underwater seascape of cold-water coral mounds offshore the southeast United States coast has been deemed the largest deep-sea coral reef habitat discovered to date, according to a paper recently published in the scientific journal Geomatics."This strategic multiyear and multi-agency effort to systematically map and characterize the stunning coral ecosystem right on the doorstep of the U.S. East Coast is a perfect example of what we can accomplish when we pool resources and focus on exploring the approximately 50% of U.S. marine
