This Is How Mapping in Paradise is Done

Insights From the First Commercial Use of Fugro RAMMS
The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradise Turks and Caicos Islands. The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradise Turks and Caicos Islands. In July 2018, Fugro embarked on a large-scale project to map the Turks and Caicos Islands for the United Kingdom Hydrographic Office (UKHO). This landmark effort called for integrated, high-resolution bathymetric, topographic and orthoimage datasets to support nautical chart updates and coastal zone management activities. To achieve the sizeable bathymetric portion of the... (read more)

Scientists Discover Roman Shipwreck Dating Back to Time of Jesus Christ

In October, a scientific team from the Balearic Institute of Maritime Archaeology Studies found a Roman cargo ship with jugs containing olive oil and perfectly preserved garum sauce, an ancient form of ketchup. Scientists have discovered the extremely large Roman shipwreck dating back to the time of Jesus Christ. The ship and its cargo could reveal new information about shipbuilding and trade during that time period. The sunken vessel was recently discovered off the coast of Greece, near Kefalonia Island, during a survey conducted by the Oceanus Network of the University of Patras, Greece. Sonar Equipment and Artificial Intelligence The... (read more)

Ancient Roman Amphorae Found in Cyprus

The Cyprus Department of Antiquities, Ministry of Transport, Communications and Works has announced the completion of the 2019 underwater archaeological mission at the Akrotiri-Dreamer’s Bay ancient port, in the Limassol District (Cyprus). Around 800 Roman amphorae dating to the end of the 6th or the 7th century AD have been found scattered over an area of approximately 130,000 sqm. This discovery has also confirmed the shipwreck of a substantial vessel for that period, the international edition of Tornos News reports. The survey was carried out by staff from the University of Southampton, Centre for Maritime Archaeology, as part of the... (read more)

Two Well-preserved 17th Century Warships Found Off The Swedish Coast

Video Included
Two large warships from the 17th century have been found by divers outside Vaxholm, an island near Stockholm, Sweden. Archaeologist divers from the new museum Vrak – Museum of Wrecks are hoping to have found the Vasa’s sister ships.  This week, maritime archaeologists at the new museum that is part of Sweden’s National Maritime and Transport Museums, have investigated historical remains in a depression in the sea bottom, outside of Vaxholm. The discovery was astonishing, according to the museum: the maritime archaeologists first discovered a shipwreck as big as the Vasa ship. It was a 17th-century warship that was most... (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)

360-year-old Shipwreck Revealed Using Virtual Reality

Video Included
Exactly 360 years to the day since the Dutch merchant ship Melckmeyt (Milkmaid) was wrecked off a remote Icelandic island, experts have harnessed virtual reality to create a virtual dive of the wreck. The Melckmeyt was on a secret trading mission when it sank during a storm. Digital archaeology specialists from Australia’s Flinders University have worked with maritime archaeologists at the University of Iceland to create a 360-degree virtual view of the wreck, which was discovered in 1992. Caption: A scene from the virtual dive, with divers swimming over the wreck as it appears today, with areas of the wreck... (read more)

Shipwreck Monitoring in the North Sea

Surveyors Discover World War One Submarine
In order to guarantee nautical depths, the Rijkswaterstaat survey department runs an annual seabed monitoring programme. In July 2019, research vessel MS Arca left its homeport of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine.

Scanning Sonar for Poor Visibility Underwater Environments

US-based Blue Robotics is launching the Ping360 Scanning Sonar, which offers small ROVs the ability to navigate in low visibility water conditions. The Ping360 is a mechanical scanning sonar – it uses a small acoustic transducer mounted on a motor that rotates it in one-degree increments. As it rotates, it transmits and receives acoustic pulses to build a 360-degree image of the surroundings. This is similar to laser scanners and LIDARs used for ground robotics and autonomous cars, but using sound waves instead of light. Maximum Water Depth of 300 Metres When mounted on a remotely operated underwater vehicle (ROV),... (read more)
