Ten Years of Exploration with AWI’s Research Aircraft Polar 5

On 1 October 2017, the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) research aircraft Polar 5 had been in service for precisely ten years. In that time, the Basler BT-67 has flown more than 1.3 million kilometres to fulfil essential scientific and logistical duties. In the course of 48 measuring campaigns, predominantly for atmospheric research and geophysics purposes, the aircraft has landed on both the Arctic sea ice near the North Pole, and at the South Pole. Polar 5 is tailor-made for polar research: in the span of eleven months, the 65-year-old plane was essentially rebuilt... (read more)

Researchers Find Japanese WWII Aircraft Carrier Destroyed in the Battle of Midway

Video Included
Deep-sea explorers scouring the world’s oceans for sunken Second World War ships have uncovered the wreck of a Japanese aircraft carrier destroyed in the Battle of Midway. Fought on June 1942, the clash saw US aircraft carriers ambush their Japanese enemies and sink all four opposing Imperial Navy (IJN) flattops, thanks partly to intelligence gained through intercepted communications. The crew of the research vessel Petrel, in conjunction with the US Navy, revealed on Friday that it had found the Japanese carrier Kaga 350 miles (560 km) northwest of Midway Island, lying at a depth of 5.4km. This week, the crew... (read more)

First UAV Flight from Unmanned Boat

The newest aircraft carrier does not have acres of flight deck. In fact, it has no deck at all. Rather than carrying a crew of thousands, it sails without a soul on board. Yet the aircraft that it operates can fly much longer and further than anything based on a fleet leviathan. That aircraft is Aerovel’s 20kg Flexrotor, which combines VTOL and a small footprint with a Hawaii-to-West Coast range. The carrier is a 4-metre skiff equipped to launch, retrieve and service the Flexrotor automatically. In what are believed to be the first-ever flight cycles of an unmanned aircraft based...

Pushing Lidar to the Limits

High-resolution Bathymetric Lidar from Slow-flying Aircraft
Airborne bathymetric Lidar is an ideal tool to study underwater features in the usually rather clear waters along the coast of Australia. Due to the remoteness of many of the continent’s coastlines, this is often the only economically viable option for large-scale bathymetric mapping at high resolution. A new toolkit consisting of two airborne Lidar systems flown on a small and slow-flying research motorglider was trialled in NW Western Australia. The same technology will be used over the next three years in the context of a comprehensive study of submerged archaeological landscapes of the so-called ’Sea Country’, more than 1,000km...

The search for Malaysian Airlines Flight 370

one of the greatest mysteries in civil aviation of this day
The Search for Malaysian Airlines Flight 370 – One of the Greatest Mysteries in Civil Aviation of this Day On 18 March 2014, Malaysian Airlines flight 370 disappeared from the radar. Now, more than two years later, only a few items of debris have been found originating from the lost aircraft. The presentation addresses the circumstances around the disappearance of the aircraft, the extensive analysis of numerous government and private industry institutions to determine the location of the aircraft, the underwater mapping and detailed search technology, the operations and the human elements, and shows some of the detailed underwater topography...

Air France Flight AF 447

A Challenge for Search and Recovery Technology
Air France flight 447, a scheduled passenger service from Rio de Janeiro (Brazil) to Paris (France), went missing on 1 June 2009 over the Atlantic Ocean with 228 people onboard. The aircraft took off from Galeão International Airport at 22:03 (UTC) on 31 May 2009 with an expected flight time of 11 hours. Contact was lost 4 hours into the flight. No distress calls were made. The recovery of aircraft parts and the ‘black-box’ recorders will be crucial to the investigation team – these tasks will challenge equipment, techniques and the ingenuity of the teams at sea.   Flight Reporting...

'As it Was'

By a Senior Hydrographer
On 8th October 1993, with the introduction of the Laser Airborne Depth Sounder (LADS) flown in a Fokker F-27 aircraft, the Australian Hydrographic Service could claim to be among the first to use airborne Lidar systems for surveying. However, this was by no means the first time aircraft had been employed in Australia for hydrographic surveying. In 1922 an Australian port chart was prepared with aerial photographic assistance of a Royal Australian Air Force (RAAF) Fairey IIID aircraft. This resulted from an experimental aerial survey undertaken in conjunction with Lieutenant Commander C. W. Stevens' boat survey of Western Port, Victoria.... (read more)

US Navy Prowler Recovered

Phoenix International, Inc. has completed a mission to locate and recover a US Navy EA6B aircraft from 58msw in the Persian Gulf. The aircraft was lost while conducting flight operations last summer. Under the direction of the Office of the USN Supervisor of Salvage, a Phoenix search and recovery team reported aboard USNS CATAWBA (T-ATF 168) in September 2003 to initiate shipboard installation of equipment. The team then deployed a Navy Centurion shallow-water side-scan sonar search system to methodically cover the initial search area. By mid-September a scattered debris field had been identified within the area and after comprehensive mapping... (read more)

Hydrographic Surveying Supporting the Search for MH370

Last week, the MH370 Safety Investigation Report was presented by the Ministery of Traffic of the Malaysian Government. On 8 March 2014, the  Malaysian Airlines aircraft went missing in the Indian Ocean. Since then, a big search operation has taken place aiming to track down the fuselage in the waters, but the aircraft was never found. The search gave, however, tons of additional data of the ocean floor to the underwater mapping community. Hydro International has followed the developments with great interest and below, you can find articles and news with great building blocks of oceanographic and hydrographic data. Increased-resolution Bathymetry... (read more)

Discovery of MH370 Part Confirms Ocean Current Models

A part from the MH370 aeroplane feared lost in the Indian Ocean on 8 March 2014 was found recently on the island of La Réunion. According to the Australian Transport Safety Bureau (ATSB) which is leading the search, this is consistent with the current underwater search area in the southern Indian Ocean where exhaustive analysis has concluded the aircraft entered the water. Drift modelling by CSIRO shows that material from the current search area could have been carried to La Réunion, among other locations. There has been more material handed over to the French police on La Réunion. However they... (read more)
