Acoustic Technology Used in Hunt for Flight Recorder at Helicopter Crash Site

A mission to search for the wreckage of an Irish Coast Guard helicopter which crashed into the Atlantic earlier this year, killing all four crew members, was supported with underwater locating equipment from Sonardyne International Ltd. Within hours of rescuers arriving at the scene of the accident off the west coast of Ireland, Sonardyne Scout USBL and ROV-Homer acoustic tracking and relocation systems, owned and operated by the country’s Marine Institute, had detected emergency signals being transmitted from the aircraft’s flight data recorder (FDR). Using an ROV, search teams were subsequently able to pinpoint the exact location of the wreck... (read more)

Oceanography Assists Rescue Hudson River Plane

Operational oceanography played a key role in the safe rescue of all 155 people on board US Airways Flight 1549 which crashed into the Hudson River on 15 January 2009, as Alan F. Blumberg of the Centre for Maritime Systems, Stevens Institute of Technology writes in the latest issue of the Journal of Operational Oceanography (JOO) published by the Institute of Marine Engineering, Science and Technology (IMarEST).   From his campus window Professor Blumberg could easily see the plane with its passengers standing on the wings awaiting rescue. He and his colleague Nickitas Georgas were able to use the Stevens... (read more)

Thomas Jefferson Rescues Downed Pilot

The pilot of a small aicraft that crashed about thirty miles from NOAA Ship Thomas Jefferson last week was rescued from the sea. The NOAA vessel was conducting mapping surveys west of Key West, FL. when it was contacted by the Coast Guard and immediately changed course to join a search and rescue operation. The crew, using the ship's Doppler speed log and GPS positioning equipment, was able to estimate the ocean current and focus their search area around a location approximately two nautical miles south-southwest of the reported crash site.The captain posted extra personnel as lookouts and used the...

Glonass Satellites Put into Orbit

Three Glonass global navigation have been successfully launched aboard a Russian Proton rocket from Baikonur space centre in Khazakstan. The Proton K rocket, which has been on the launch pad since Monday, lifted off on 26th October at 11.35 a.m. Moscow time (7.35 a.m. GMT) and put in orbit, according to the Russian Information Agency (RIA) Novosti.   Kazakhstan lifted a ban Wednesday on Proton launches from the Baikonur space center, which Russia rents from the ex-Soviet Central Asian country. The ban was imposed following a September 6 crash of a Proton-M.     (read more)

German Oceanographers Provide Further Insights into MH370

For the past 16 months an extensive search has been underway for the missing Boeing 777 of Malaysia Airlines (MH370) in the Indian Ocean. Since a piece of debris was discovered a few weeks ago on the island of La Réunion, oceanographers in Kiel, Germany, have been attempting to trace the origin of the flaperon that is presumed to belong to the missing Boeing. The results of their recently completed computer model simulations show that the debris found on La Réunion probably originates from the eastern equatorial Indian Ocean. However, substantial uncertainties are making it difficult to pinpoint the area... (read more)

MoD Buys Second SCOUT for Underwater Tracking

The UK Ministry of Defence (MoD) has ordered its second SCOUT underwater tracking system from Sonardyne International Ltd. The MoD was the first military organisation to invest in the newly developed system when it purchased its first SCOUT in February this year. The second system will also join the inventory of the Defence Logistic Organisation’s Salvage & Marine Operations Integrated Project Team, which is expected to use it to track ROVs and divers during surveys of wrecks and aircraft crash sites. The SCOUT systems will form part of the MoD’s salvage equipment inventory, capable of deployment at short notice by... (read more)

Navy Fleet Survey Team Gets New Commanding Officer

The U.S. Navy's Fleet Survey Team (FST) at the John C. Stennis Space Center in South Mississippi saw Cmdr. Brian D. Connon as Commander taking command from former Commanding Officer Cmdr. Todd Monroe in a ceremony held 3 August 2006. Connon had most recently served as an oceanographic assignment and placement officer at the Naval Personnel Command in Millington, Tennessee. The FST is a 50-member team comprised of civilians and active duty Navy officers and enlisted personnel. The bulk of its officers are Category-A certified hydrographers with graduate degrees in hydrographic science. Members of the FST perform hydrographic surveys in... (read more)

GeoAcoustics DeepTow 2000 Detects Crashed Aircraft

Incostas has detected an aircraft that crashed in the Carribean Sea on 4th January 2008 with the help of their GeoAcoustics Deep Tow. The aircraft, carrying 14 people on route between Caracas, Venezuela and the Los Roques islands, was 24 miles south of its destination at the time of the crash. On 9th April Incostas mobilised their GeoAcoustics Deep Tow 2000 side scan to undertake a search for the aircraft in approximately 400 metres water depth on board the vessel Punta Brava from the port of La Gauaira.   Due to the versatility of the side scan sonar it was...

U.S. Coast Guard Evaluates Underwater Imager

The Underwater Inspection System (UIS) from CodaOctopus has been the subject of evaluation by the United States Coast Guard Research and Development Center (USCG). An interim report provides an update on the USCG findings so far and on some of the operations in which the systems were deployed by the USCG teams. The USCG has a number of UIS systems and has worked with CodaOctopus in developing the functionality further. The report which provides an update on their evaluation to date states, in part, that these systems have been deployed in various and varied operations such as the recent helicopter... (read more)

ROVs for Government Agencies

US Government agencies, including the US State Department, a US Navy maintenance facility, and an Emergency Management Agency in Wyoming, are purchasing JW Fishers SeaLion ROVs. An official at the Navy facility in Washington said their group had spent a considerable amount of time researching the various ROVs on the market today. The SeaLion best fit their requirements for power, rugged construction, and cost.   The SeaLion utilises a six motor propulsion system; four horizontal thrusters and two vertical. This arrangement provides the power to operate in currents up to 3 knots and to "drag" extended lengths of umbilical in... (read more)
