TerraSond announced plans to invest in a new base in Massachusetts as part of its commitment to support the Vineyard Wind 1 project and wider US offshore wind developments. The company, which already has facilities in Alaska and Texas, has been confirmed as a preferred supplier for the subsea balance of plant inspection and survey services for the Vineyard Wind 1 wind farm, a joint venture between Avangrid Renewables and Copenhagen Infrastructure Partners. The wind farm will be situated 15 miles south of Martha’s Vineyard and Nantucket, and 35 miles from mainland Massachusetts.

Thomas Chance founded C & C Technologies in his home in 1992. Today C & C is a global oil field surveying and mapping company with more than 550 employees in ten offices worldwide. C & C was the first company in the world to offer autonomous underwater vehicle (AUV) survey services to the oil industry and remains a world leader in the field. In April of 2015, he sold C & C Technologies to Oceaneering International. Complementing the autonomous underwater vehicle business, Mr. Chance started Autonomous Surface Vehicles, Ltd., or ASV, in 2010. ASV has 140 employees, four offices across the globe and has built more than 100 state-of-the-art unmanned boats for the defense and commercial sectors.

ASV Global has announced it will be demonstrating its C-Worker 5 Autonomous Surface Vehicle (ASV) at the Ocean Business exhibition in Southampton, 4-6 April 2017. Designed, built, and operated by ASV Global, C-Worker 5 is the ideal platform to support construction and survey operations in combination with cutting-edge hydrographic, positioning and communication systems from leading manufacturers such as Kongsberg Maritime. The 5.5m ASV is designed for up to 7 days endurance at survey speeds of up to 7 knots, minimising launch and recovery operations and increasing survey efficiency. C-Worker 5 will be hosting a variety of Kongsberg Maritime systems during the demonstration, including EM2040P, Seapath 130, MicroPAP and Maritime Broadband Radio.

ASV Global and TerraSond have completed a 5172 nautical mile hydrographic survey in the Bering Sea, off Alaska. TerraSond used the C-Worker 5 Autonomous Surface Vehicle (ASV) alongside its Q105 survey ship for a duration of 36 days. The C-Worker 5 completed 2275 nautical miles of survey lines operating as a force multiplier, running parallel survey lines to the Q105. Both vessels ran multibeam sonars and simultaneously towed side scan sonars. The C-Worker 5 was operated using ASV Global’s ASView control system from a control station on the Q105 vessel. ASView used exported survey lines from the TerraSond planning system to autonomously execute an accurate survey with minimal human intervention.

Over the next decade the maritime sector is likely to see one of the largest changes since sail gave way to steam. Unmanned Surface Vehicles (USV) are now being considered for various marine roles and the drivers for rapid development are significant. Unmanned or autonomous vessels have passed through the trial and evaluation stage and are now being adopted for civilian and military applications. The maritime sector now has the opportunity to shape technology developments from legislative and end-user standpoints.

NOAA announced the official launch of its 2015 Arctic hydrographic survey season took place this morning, in Kodiak, Alaska, in a World Ocean Day ceremony which showcased the deployment of the NOAA ships Rainier and Fairweather. “Most Arctic waters that are charted were surveyed with obsolete technology, with some of the information dating back to Captain Cook's voyages, long before the region was part of the United States,” said NOAA deputy under secretary for operations Vice Admiral Michael S. Devany in remarks directed to the crews of NOAA ships.

539 N. TerraSond is a leader in precision geospatial solutions providing professional survey and geophysical services in both terrestrial and marine environments safely, effectively and economically. TerraSond employs ACSM Certified Hydrographic Surveyors, staff hydrographers, marine geophysicists, geologists, oceanographers, cartographers, GIS / CADD specialists and IT and professional mariners. Clients include oil and gas, pipeline, renewable energy, shipping, dredging and construction industries.

TerraSond says it has been selected by the National Oceanic and Atmospheric Administration (NOAA) to provide hydrographic surveying services anywhere in the U.S under a new five-year contract. Under the new contract beginning in 2015, TerraSond will provide comprehensive, modern hydrographic surveys in assigned areas to support NOAA’s nautical charting mission, which includes the updating of charts in critical areas for navigation safety. TerraSond adds that it has been providing hydrographic survey services continuously for NOAA since 1998 under consecutive multi-year contracts. During this time, TerraSond has completed more than 79 separate surveys from the Gulf of Mexico to the Arctic, with three additional surveys currently underway in 2014.

TerraSond Limited announces the return to home base in Alaska of its multi-purpose survey boat 'Luna Sea'. The owners say that this strategic return enhances their capability to serve clients in the Cook Inlet and South Central Alaska. Headquartered in Palmer, Alaska with offices worldwide, TerraSond has a long history of providing high quality geospatial, geophysical, and geoscience survey solutions dedicated to imaging the earth worldwide. The Luna Sea is well suited for performing a wide range of hydrographic and geophysical surveys.

A number of archaeological groups and marine service companies are acquiring boat-towed metal detectors to assist in locating shipwrecks and to perform geophysical surveys. These devices can locate a variety of targets including the piles of magnetic ballast stones found on many old wrecks, gold and silver bars, cannons, anchors, pipelines, cables, and various metal debris which must be removed from an area before dredging. The two primary pieces of equipment used in these operations are a magnetometer and pulse induction (PI) metal detectors.

A new high resolution seafloor survey of Pribilof Canyon in the eastern Bering Sea reveals dramatic details of this undersea canyon, and provides information for improved fisheries conservation and management; in particular, provide identification of areas that are potentially hazardous for loss of commercial fishing gear. Previously, only incomplete lower-resolution data were available to describe the morphology of this world-class feature. Pribilof Canyon is one of a family of huge canyons that play a central role in supporting the rich ecosystem of the Bering Sea.
