Dozens of perfectly preserved ancient shipwrecks have been found at the bottom of the Black Sea. A total of 60 wrecks were discovered dating back as far as 2,500 years, including galleys from the Roman, Byzantine and Ottoman empires. Scientists stumbled upon the graveyard while using underwater robots to survey the effects of climate change along the Bulgarian coast. Because the Black Sea contains almost no light or oxygen, little life can survive, meaning the wrecks are in excellent condition. Researchers say their discovery is'truly unrivalled'.

Reports of satellite navigation problems in the Black Sea suggest that Russia may be testing a new system for spoofing GPS, New Scientist has learned. This could be the first hint of a new form of electronic warfare available to everyone from rogue nation states to petty criminals. On 22 June, the US Maritime Administration filed a seemingly bland incident report. The master of a ship off the Russian port of Novorossiysk had discovered his GPS put him in the wrong spot – more than 32 kilometres inland, at Gelendzhik Airport. After checking the navigation equipment was working properly, the captain contacted other nearby ships.

In this study, the wind data series from five locations in Aegean Sea islands, the most active `hotspots' in terms of refugee influx during the Oct/2015 - Jan/2016 period, are investigated. The analysis of the three-per-site data series includes standard statistical analysis and parametric distributions, auto-correlation analysis, cross-correlation analysis between the sites, as well as various ARMA models for estimating the feasibility and accuracy of such spatio-temporal linear regressors for predictive analytics. Strong correlations are detected across specific sites and appropriately trained ARMA(7,5) models achieve 1-day look-ahead error (RMSE) of less than 1.9 km/h on average wind speed. The results show that such data-driven statistical approaches are extremely useful in identifying unexpected and sometimes counter-intuitive associations between the available spatial data nodes, which is very important when designing corresponding models for short-term forecasting of sea condition, especially average wave height and direction, which is in fact what defines the associated weather risk of crossing these passages in refugee influx patterns.

Researchers have developed the world's first autonomous, zero-emissions cargo ship. The vessel could dramatically reduce diesel emissions from conventional cargo ships. The vessel, developed by agriculture company Yara International ASA and high-technology systems firm Kongsberg Gruppen, will be loaded and unloaded automatically using electric cranes. Researchers have developed the world's first autonomous, zero-emissions cargo ship: The Yara Birkeland. Developed by agriculture company Yara International ASA and high-technology systems firm Kongsberg Gruppen, will be capable of autonomous mooring and route planning.

Robots in Service of the Environment has designed an underwater robot to combat a growing problem in the Atlantic Ocean: the invasive lionfish.

Undoing man's folly is, sometimes, a robot's work. Unwittingly introduced to the Atlantic Ocean over a quarter of a century ago, the lionfish, which is native to the Pacific, is responsible for an ecological disaster of epic proportions in the Caribbean, Bermuda's, and off the shore of Florida coast, and it's spreading up the coast. A complete lack of predators, voracious appetite and ability to reproduce at an astonishing rate has resulted in a mushrooming lionfish population that is decimating ecosystems, coral reefs and the fishing business. SEE ALSO: A fish that doesn't belong is wreaking havoc on our ocean Catching and eating lionfish, which are delicious, sounds like a reasonable solution, but the fish can't be netted, and are generally fished one person and one spear at a time. If fisherman can't catch lionfish en masse, they can't sell them at quantities to food stores and restaurants.

I am in an aeroplane crossing the Atlantic Ocean as I write this. We took off from Heathrow Airport more than three hours ago. By now, it's likely the plane's captain and crew are not physically in control of the aircraft. Something as complex as flying a metal tube packed with more than 300 living souls at 12,000 metres and 900kph is left to a computer and a set of algorithms. Such a device is badly needed in our hospital wards.

MOSCOW – Search teams on Wednesday recovered another flight recorder from a military plane that crashed in the Black Sea, killing all 92 aboard, the Defense Ministry said. The first flight recorder was found the previous day and experts have started analyzing its data to determine the cause of the crash. The Tu-154 of the Russian Defense Ministry crashed into the sea early Sunday, two minutes after taking off in good weather from the city of Sochi. It was carrying members of the Alexandrov Ensemble, widely known as the Red Army Choir, to a New Year's concert at a Russian military base in Syria. The Defense Ministry said 15 bodies and 239 body fragments have been recovered from the crash site.

TOKYO SoftBank Group Chairman and CEO Masayoshi Son showed me a photo on his iPhone and said, "I will never forget this scene for the rest of my life." The photo showed a group of white yachts in a bay under an endless blue sky in Marmaris, a port town in southern Turkey. Son swiped the screen, and a selfie photo of him in chino pants and a casual shirt appeared. Several hours before the photos were taken on July 4, Son met Simon Segars, CEO of ARM Holdings, and Stuart Chambers, chairman of the British computer chip design company, on the second floor of a restaurant overlooking the bay. Chambers had arrived in Marmaris, a popular resort town, after receiving an unexpected phone call from Son while yachting with his family in the Mediterranean Sea.

Wärtsilä's strong commitment to developing the technologies, the system reliability, and the essential designs to enable the viability of autonomous shipping is again emphasised through its participation in an important research programme. Together with other leading marine sector and information & communication technology (ICT) companies, Wärtsilä is supporting a project aimed at creating the world's first autonomous marine transport system. The initial focus will be on developing a fully autonomous system for the Baltic Sea by the year 2025, with cargo ships and freight transportation being the first pilot applications. The programme is being largely financed by Tekes, the Finnish Funding Agency for innovation and the ecosystem platform is being handled by DIMECC, a leading breakthrough oriented co-creation ecosystem provider. The main corporate investors in the programme, apart from Wärtsilä, are Rolls-Royce, Cargotec, Ericsson, Meyer Turku, and Tieto.
