Ferry routes are also more clearly labelled than before, and Google Maps will estimate a ferry time  based on its timetables if users try planning a route for their journey.
(example in Italy with the Marine GeoGarage)

We’ve also added better and more clearly labelled ferry routes in many places, such as the area below surrounding Naples, Italy.
Traveling by ferry is one of my favorite ways to explore a city—I love looking back from the water at the cityscapes—and this improvement will help you find the ferry routes you need to do the same. You can even use Google Maps to get transit-based directions for ferries.
We take into account ferry timetables to route you over water just easily as you might follow our driving directions over land.


Become an Antarctic explorer with panoramic imagery (from Google LatLong)

In the winter of 1913, a British newspaper ran an advertisement to promote the latest imperial expedition to Antarctica, apparently placed by polar explorer Ernest Shackleton.
It read, "Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honour and recognition in event of success."
While the ad appears apocryphal, the dangerous nature of the journey to the South Pole is certainly not—as explorers like Roald Amundsen, Robert Falcon Scott and Shackleton himself discovered as they tried to become the first men to reach it.

Back in September 2010, we launched the first Street View imagery of the Antarctic, enabling people from more habitable lands to see penguins in Antarctica for the first time.
Today we’re bringing you additional panoramic imagery of historic Antarctic locations that you can view from the comfort of your homes.
We’ll be posting this special collection to our World Wonders site, where you can learn more about the history of South Pole exploration.


With the help of the Polar Geospatial Center at the University of Minnesota and the New Zealand Antarctic Heritage Trust, we’ve added 360-imagery of many important spots, inside and out, such as the South Pole Telescope, Shackleton's hut, Scott’s hutCape Royds Adélie Penguin Rookery and the Ceremonial South Pole.

Garbage-eating drone destroys ocean pollution



From EarthTechling

Drones have been a hot topic in the media lately.
Whether they’re for surveillance or combat, the idea of drones patrolling our airspace is one that’s not taken lightly by the public.
As we struggle to work out the ethics and legalities of military drones, it’s important to remember that not all autonomous robots are designed for violence or espionage.



Many of us enjoy the work of drones in our daily lives, like the Roomba vacuum, BUFO pool cleaner, or Bosch Indego autonomous lawn mower.
These self-sufficient robots perform routine tasks that normally take a lot of time away from our daily lives.
They also make it possible to conduct tasks that would be costly or dangerous if carried out by a human.
The Marine Drone concept created by Elie Ahovi and his team of collaborators, is a perfect example of a way drone technology can have a positive impact on our world.


Unlike the drones that have been causing so much controversy, this robot is designed to operate underwater, and instead of seeking out enemy targets, it will search for and destroy something equally sinister–ocean garbage.
Horrified by the size of the Great Pacific Garbage Patch, and its identical twins forming in oceans all over the world, Ahovi and his classmates from the French International School of Design decided to come up with a simple-yet-sophisticated solution.

As this review points out, the Marine Drone would patrol the oceans autonomously, sucking plastic bottles and garbage into its maw like a butterfly net.
Powered by water-proof batteries, the Drone would employ an electric motor to move silently through the water.


Like these pollution-seeking robot fish, the Drone’s sonic emitter would send out an irritating signal to deter aquatic life, ensuring that only trash goes into the net.
When it’s collection area is full of junk, the Drone would dock with a nearby mothership, where a crew would crane the garbage up for disposal.

Royal Navy finds uncharted Red Sea mount‎

Royal Navy survey ship HMS Echo has discovered a previously uncharted underwater 'mountain' on the bed of the Red Sea the size of the rock of Gibraltar.

The hi-tech sonar suites of the Devonport-based survey ship mapped the huge feature for the first time, and it will now be marked on charts to prevent other seafarers running into it.

Echo was sent east of Suez at the beginning of last year to help improve charts of the region's waters and gather key hydrographic data.
The enormous mound – the correct term is 'sea mount' is quite literally the biggest success of Echo's deployment.

Yemeni fishermen evidently knew the mount existed – Echo found a dhow anchored on its summit as she carried out her survey of the area.

Existing charts of the area suggested the sea was 385m (1,263 feet) deep, but over an eight-hour period Echo collected reams of information with her sounders to prove otherwise.

24 hours later, after processing all that information, the survey ship's powerful computers produced stunning 3D imagery which revealed the true extent of the mount.

It rises to just 40m (131ft) below the surface of the Red Sea – deeper than the deepest draught of any civilian or military surface ship, but a definite danger to submarines passing between the Mediterranean and the Middle East.

"We were actually looking for volcanoes – the southern Red Sea region has seen a significant amount of recent tectonic and volcanic activity with several volcanoes emerging from the sea close to the Yemeni coast line," said Commander Matt Syrett, Echo's Commanding Officer.

"We didn't find any. But we did find this. It is absolutely massive, and finding it is something which really makes everybody on board feel good.
"So often it's difficult to show that what the Navy does has a tangible effect. This is visible proof. We found it and, as it's a danger to other seafarers, it's been reported to the United Kingdom Hydrographic Office and is expected to appear on new charts of the region in the near future."

Now in the Mediterranean, Echo's finds have continued with the possible wreck of a Second World War 'Liberty Ship' a dozen or so miles off Tripoli. Standing 22m (72ft) proud of the seafloor, 105m (344ft) long and 22m wide; the object is the length of 11 double decker buses parked in nine rows and stacked five deep.

Once again the UK Hydrographic Office, which provides charts for the Royal Navy and many of the world's merchant mariners, has been informed so other sea users can be warned of Echo's discovery.

"From the shape of the hull and location of the superstructure it is likely to be an old Liberty Ship, and was most likely another casualty of World War 2," said Cdr Syrett.

In the 18 months since Echo left UK waters, she has carried out a wide range of essential survey tasking, from supporting assault ship HMS Albion during amphibious exercises in the Gulf last summer, to improving navigational safety for merchant shipping in the Gulf and Red Sea and carrying out oceanographic research off the Horn of Africa.

Shark attacks prompt calls to review the great white's protected status


From TheGuardian

The government of Western Australia has called for the national protected status of the great white shark to be reviewed after the state suffered its fifth fatality from the ocean predator in the past 10 months.

Ben Linden, a 24-year-old musician from Perth, was killed in a shark attack while surfing near Wedge Island, 160kn north of the state capital.
A jetski rider who attempted to retrieve Linden's body was knocked off his vehicle by the shark.
Police and volunteers are searching nearby beaches for the surfer's remains, although a hunt for four- to five-metre long sharks in the vicinity was unsuccessful and has been called off.

Western Australia's fisheries minister, Norman Moore, said he was "very distressed" by the latest fatality and said he would lift the great white's protected status if the federal government – which has ultimate jurisdiction over protected species – did the same.

Citing concerns over the impact on tourism to the state, Moore said he would push Canberra to allow commercial and recreational fishing of great whites, although he stopped short of calling for a concerted shark hunt or the setting up of protective nets.
"They have been protected by the Commonwealth and by the state for about 20 years because they were considered to be a threatened species," he told reporters.
"But there seems to be a view that there's an increase in the number of great whites within our waters in recent times.
"Regrettably, people are being taken by sharks in numbers which we have never seen before.
"We need to try to work out to the best of our capacity what is causing this to happen. I'm totally perplexed."


Conservationists have cited an increase in extreme sports and surfing as contributing to the attacks, with environmental group The Wilderness Society calling the hunt for culprit sharks a "Neanderthal" reaction by authorities.

However, Western Australia has seen an unusual number of attacks, with five deaths since September last year.
Globally, there have been four fatalities from shark attacks so far this year.
In 2011, there were 12 deaths from "unprovoked" shark attacks.

This number is dwarfed by the number of sharks killed by humans, with tens of millions slaughtered each year just for shark fin soup.

Dark secret of the Lusitania


From DailyMail

Was the Lusitania Britain's war crime?
1,198 passengers died in 1915 when the liner sank - but was a German torpedo really to blame?


Within seconds of the initial shock, the great passenger liner listed and began to sink, her four funnels belching smoke.
Women and children shrieked in panic, and lifeboats half-full of people swung drunkenly from their davits, some crashing on to the deck, crushing other passengers.
A familiar picture – yet this is not the Titanic going down, but her lookalike, rival trans-Atlantic liner, Cunard’s RMS Lusitania, which sank off the Irish coast with the loss of 1,198 lives on 7 May 1915, three years after the Titanic went down.

And while the Titanic’s end had a natural cause – a collision with an iceberg – the Lusitania was sunk by a German U-boat torpedo. Or was it?
In the century since the catastrophe, debate has raged about what exactly caused the liner, among the largest in the world, to sink in just 18 minutes – the Titanic took almost three hours to go down.
Although the Lusitania was certainly struck by a German torpedo, survivors reported hearing a second explosion, which caused the fatal damage.
Now, as part of a TV documentary, a diving team has visited the wreck to find out what caused this mysterious second blast.

The Lusitania, which had left New York bound for Liverpool six days earlier with almost 2,000 passengers and crew on board, had been known to be carrying small-arms ammunition to supply the British Army, then grappling with the Germans in Flanders in the midst of World War I.
But soon after the sinking, rumours circulated that the ship had also been carrying explosives destined for the front.
Endangering innocent civilians in such a way – if proved – could constitute a war crime almost as serious as the U-boat’s targeting of the passenger liner, an atrocity that helped bring the US into the war against Germany in revenge for the many Americans who died.
In its time, the sinking of the Lusitania had all the shock impact of 9/11.
Today, the ship lies 300ft down, 12 miles off the south coast of Ireland near the port of Cobh.

 First underwater visit in 1935 by James Jarret English diver who located the wreck with ASDIC

In 1968 American businessman Gregg Bemis became a co-owner of the wreck, which had been bought the previous year by a US diver for £1,000.
Bemis, who subsequently became sole owner, fought a long battle in the courts for the right to dive and explore the ship, which still contains the remains of hundreds of victims.
It also holds valuable items, but Bemis, now 83, says, ‘When I was younger it was the monetary value that most interested me. But today it’s the history – all the people on board had lives like you and me that were brutally cut off on that May day.’
Bemis is certain that the Lusitania was carrying an illicit cargo of high-explosive gun-cotton which, he believes, caused the blast that sank her so quickly.
The expedition he joins for the documentary aims to prove whether he is right.


The diving team plan to cut out a section of the liner’s hull, locate where any explosive was stored and find evidence of what caused the second explosion.
But just getting down to the Lusitania is hard.
‘The water is incredibly murky,’ says Eoin McGarry, one of the dive team.
‘Although the Lusitania lies in much shallower water than the Titanic, which is 12,000ft down, it’s still difficult to see your hand in front of your face.’
There is also an emotional aspect to diving to the wreck, which McGarry describes as ‘like travelling back in time to visit a graveyard’.

In August of 1993, Dr. Robert Ballard, the discoverer of the Titanic and the Bismarck, led an expedition to the wreck of the Lusitania, off the coast of Ireland.
Using a small submarine and remotely controlled camera vehicles, Ballard and his team studied the wreck like a team of underwater detectives trying to solve a murder mystery. (book/video)

To add to their problems, the divers have only a narrow window of opportunity before worsening weather forces their ship back to port.
First, they have to pinpoint the position of the liner’s magazine, the room set aside for explosive material (the ship had been built on the understanding she might be converted for military use, but never was), then clean off the sediment on the exterior and cut their way into the wreck…
They manage it with just minutes to spare, and crawl deeper into the liner’s interior than anyone before.

The image shows one of the starboard forward deck mooring bollards still intact
with their original rope lashed into position.
British Technical diver Mark Jones was expedition leader of 3 successful expeditions to the wreck from 1999-2001.

They find the small-arms ammunition the Lusitania had been known to be carrying – and gather enough photographic data for experts at a California lab to make an informed guess about what caused the blast that sent the ship to the bottom.

‘There are only three possibilities,’ says Bemis.
‘Either the torpedo ruptured one or more of the ship’s 25 boilers, causing an explosion; or it set off a coal dust explosion in the coal bunkers; or it triggered a gun-cotton or aluminium-powder explosion – which would mean the Lusitania was carrying dangerous high-explosives, unknown to the passengers who died. And that would have been a war crime on a par with the action of the U-boat that fired the fatal torpedo.’
So what did the scientists at the laboratory decide?
