France SHOM update in the Marine GeoGarage


new update in the France (SHOM) layer



1 chart has been added & 1 chart withdrawn since the last update (March 2014) :

  • 7659   De Cabo de Gata à Cabo de Las Huertas et de Cap Milonia à Cap Ivi (replacing chart 3678   Côte de l'Algérie (1ère feuille), d'Alger à la frontière du Maroc)
All the other charts have been updated according to the new editions :


Note : in our catalogue of 597 charts from SHOM, we have also temporary withdrawn in this new update some charts mainly in foreign areas managed by SHOM which were badly georeferenced (local datum issues)
- for example (list non exhaustive)6624, 6688, 6689, 6690, 6691, 6692, 7014, 7504, 7507 ...
All these charts will be re-include in a next update on our GeoGarage platform.



By the way some of our users ask us why some general charts -which are displayed in the official portal of the SHOM - are not displayed in the GeoGarage.
The reason is that these charts are facsimilés of international (INT) charts from UKHO, IHM Spain, IIM Italia or NHS Norway for example : so these charts have some copyrights which are not managed by our commercial license with SHOM
- for example (list non exhaustive)6608 (NO301), 6618 (GB4102), 6898 (NL2003-GB 4402), 7015 (ES4C), 7210 (GB2649), 7292 (IT434)....

Today 751 charts including sub-charts from SHOM material are displayed in the Marine GeoGarage.

The ungoverned seas

The waters around Somalia are calmer, but piracy in west Africa is rising

From The Economist

STICK-SLIM and still, Captain Lube sits in Lagos’s commercial fishing harbour, watching his crew clean a rusting shrimp trawler.
He used to look forward to guiding them out to the rough Atlantic waters.
But nowadays he has grown too afraid to venture far from the coast.
Pirates infest west Africa’s seas, and he has seen many fellow captains kidnapped and sometimes killed.
He has become jumpy; every approaching vessel might pose a danger.
The trawling company for which he works says that attacks last year were “too many to count”.

Just a few years ago the most dangerous waters in the world were off the coast of Somalia.
But piracy there has fallen dramatically.
It is more than two years since Somali pirates last successfully boarded a ship.
At their peak in 2011, attacks were taking place almost daily.
The number of attempts has fallen to a handful every month.
Now it is the Gulf of Guinea that is the worst piracy hotspot, accounting for 19% of attacks worldwide, as recorded by the International Maritime Bureau.
It registers an attack nearly every week (see map).
The numbers are probably underestimates. America’s Office of Naval Intelligence reckons the real figure is more than twice as large—and growing.

The nature of piracy is quite different on the two sides of the continent.
Around the Horn of Africa in the east, Somali pirates seek to seize ships and crews for ransom, and have ventured deep into the Indian Ocean.
In the Gulf of Guinea in the west, attackers are more intent on stealing cash and cargoes of fuel, such as diesel, from ships coming in to port.
Crews are sometimes kidnapped.

It is a quicker hit than the Somali hostage-taking.
It also tends to be more violent because the attackers have little incentive to keep the crews safe.
Armed resistance is often met with heavy machine guns and military tactics, says Haakon Svane, of the Norwegian shipowners’ association.
Ships are seized for a few days, anchored quietly and cargoes are siphoned off into smaller vessels.


The gangs also appear to have good intelligence, security sources say: they often know which ships to attack and they recruit the skilled crewmen needed to operate the equipment.

Frequently the targets are themselves involved in regional smuggling, so they switch off transponders or assume false identities, making it hard for rudimentary anti-piracy forces to keep track of them. Moreover, they do not report attacks.

Incidents have stretched all the way from the Ivory Coast to Angola, but the root of the problem lies in Nigeria.
Most acts of piracy are committed in Nigerian seas, by Nigerian criminals.
The trouble at sea is ultimately tied to the country’s dysfunctional oil industry and the violent politics of the Niger Delta, where most of the oil is produced.
Nigeria is the world’s eighth-largest oil producer; nevertheless, it suffers from shortages of refined fuels.

Widespread “bunkering” (the term Nigerians use for the theft of oil) and a violent insurgency created the conditions for piracy to flourish.
Analysts say there tend to be spikes in both bunkering and maritime criminality before elections, which may mean that politicians are using illicit means to finance themselves.
If so, expect pilfering to rise as Nigeria’s presidential vote nears in February.
“The ransoms are used for the elections,” says Hans Tino Hansen, managing director of the Risk Intelligence consultancy.
He points to a “feudal system” in which politicians protect pirates in return for a cut of their profits.
An added problem is that elections may divert the attention of the security agencies.

Atalanta on the Atlantic?

Some of the smaller countries in the region have appealed for help from the world’s navies.
The success of various task forces, including the European Union’s Operation Atalanta, in dealing with criminality off east Africa leads people to ask why they should not repeat the job off the west coast.
After all, about 12% of Europe’s imported oil comes from west Africa.

But years of anti-piracy operations around the Horn of Africa have strained navies.
On the plus side, they have led to unprecedented international co-operation: for the first time since the second world war all five permanent members of the UN Security Council have deployed forces on the same side.
Among those guarding these sea-lanes are forces operating under national, EU and NATO commands as well as club-like structures such as the Combined Maritime Force (CMF), whose anti-piracy mission is headed by a New Zealander.

Against that, however, officers complain that their crews are missing training for what they see as their main mission of high-intensity warfare.
In addition, ships operating around Somalia wear out more quickly than those in other waters—dust and sand in the air damage their engines and the high temperatures harm electronics designed to operate in cooler Atlantic or Mediterranean waters.

Hence the NATO component of the anti-piracy force, which usually comprises four or five ships, is down to two—and securing these was a stretch.
The EU force, which was meant to have disbanded this year, will now keep going until 2016. It is currently commanded from the decks of an Italian destroyer, the Andrea Doria.

Western countries are reluctant to get sucked into another commitment on Africa’s western coast.
One reason is that attacks take place in territorial waters, where they count as “armed robbery at sea”.
Dealing with them is the job of littoral states, not foreign navies (in Somalia, a failed state, UN resolutions authorised force in the country’s waters and on land).

Another is that, despite the oil, sea traffic around west Africa is small compared with the arteries connecting Europe and Asia through the Suez Canal.
And although piracy in the east has been subdued for the time being, nobody thinks the problem will end until stable government is restored to Somalia.
Indeed, the threat of resurgence may be growing given the thinning numbers of warships and the money-saving risks that shipowners are starting to take (sailing closer to Somalia, at slower speed and with fewer armed guards).

In short, nobody wants to become bogged down in another open-ended naval operation.
The success around the Horn of Africa was because of a mixture of factors—intense patrolling by international navies, the deployment of armed guards on ships and defensive action by crews.
It may be harder to reproduce that combination in the Gulf of Guinea.

In the narrow Gulf of Aden, for instance, ships were encouraged to sail fast and in convoys to make it harder for pirates to board; passive defences (such as bullet-proof rooms) and guards could buy enough time for warships nearby to come to the rescue.
But in west Africa the most vulnerable ships are either at anchor or are lining up to come in and out of port.
Nigeria has refused to allow ships to bring armed guards into its waters.
Some that have tried have had their crews arrested and charged with arms smuggling.

West African states are trying to strengthen their coast guards with Western help, and efforts are being made to share information on shipping and attacks.
But if there is to be a halt to piracy Nigeria will have to take the lead in patrolling its own waters and curbing illegal activity.
Given the country’s inability to deal with an insurgency by Boko Haram militants in the north—a double suicide-bombing this week killed scores of people in the town of Maiduguri—there is little reason to think that it will have much success in protecting its waters.
The worry is that piracy, itself, is becoming enmeshed with drugs- and arms-smuggling networks linked to violent jihadist groups in the Sahel.

Suez canal scheme ‘threatens ecosystem and human activity in Mediterranean’

Scientists say new channel will herald arrival of more invasive species,
with potentially harmful impact on region as a whole
The human activities/interventions mostly responsible for marine biological invasions in the Mediterranean Sea: 
(1) the opening of the Suez Canal connecting the Red Sea and the Mediterranean;
(2) shipping (the color of the marine area indicates the intensity of maritime activities: blue is low, red is high ;
(3) aquaculture (surveyed in 2006; red dots: shellfish; yellow dots: fish cages).

From The Guardian by Patrick Kingsley

The continuing expansion of the Suez canal risks causing serious harm to marine lifeforms and economic activity in the Mediterranean sea, scientists are warning.

Egypt is building a second “lane” to the Suez canal, as well as widening the existing channel, in an “ominous” scheme scientists fear could allow greater numbers of non-indigenous species to enter the Mediterranean and endanger the native ecosystem.


“The enlargement of the canal will increase the number of invasions from the Red Sea resulting in a diverse range of harmful effects on the ecosystem structure and functioning of the whole Mediterranean sea, with implications to services it provides for humans,” Bella Galil, a marine biologist at Israel’s National Institute of Oceanography, told the Guardian.

Writing in the Biological Invasions academic journal, Galil and 17 colleagues accept that the expansion will go ahead despite their concerns, and acknowledge that the revenues from an enlarged canal are likely to bring Egypt a much needed economic boost.

But they ask Egypt to first conduct an impact assessment to determine the project’s likely environmental footprint, and any preventive measures to mitigate the dangers ultrasound, and increased salinity in certain parts of the canal.

There are about 700 non-indigenous species in the Mediterranean, according to the scientists, about 350 of which have entered from the Suez Canal since its construction in the late 19th century.
Some of these species “are noxious, poisonous, or venomous and pose clear threats to human health”, while others have destroyed the habitats of local creatures.

Among the most destructive recent entrants from the Suez is the silver-cheeked pufferfish, a non-native fish containing toxic chemicals that has caused several people to be treated in hospital in the eastern Mediterranean in the past 10 years.
Two kinds of herbivorous rabbit-fish – the dusty spine-foot and its cousin the marbled spine-foot – have destroyed vast swaths of underwater seaweed forests in the eastern Mediterranean, after migrating through the Suez in recent decades.

Perhaps the most dangerous newcomer is the nomad jellyfish, orRhopilema nomadica.
Once only found in tropical waters, the nomad jellyfish invaded the Mediterranean via the Suez in the 1970s.
Now its vast swarms, which can measure tens of miles in width, frequently make commercial fishing impossible and have sometimes closed tourist beaches lining the Mediterranean for days at a time.

“This isn’t just about the effect on other species,” said Stefano Piraino, a jellyfish expert at the University of Salento, and one of the 18 signatories.
“We’re talking about a threat to human life and human activity, including tourism, agriculture, and fisheries.”

Some of the jellyfish have temporarily disabled power stations lining the eastern Mediterranean, after the swarms became stuck in the stations’ seawater-powered cooling systems.
Nearby fishermen have found their catches ruined for similar reasons. “Jellyfish can be 90% of the catch – and the remaining fish are very damaged, so the value of the fish is greatly reduced,” said Piraino.

This year, researchers at the university of East Anglia estimated that jellyfish from the Suez would cost fishermen in the northern Adriatic sea – which is only a small part of the Mediterranean – €8.2m (£6.5m) in financial losses.

The 18 scientists have called on signatories to the Convention of Biological Diversity, a UN-organised pledge to conserve the world’s ecosystems, to press Egypt to conduct an impact assessment into the environmental effects of the canal expansion.

Responding to the call, Braulio Ferreira de Souza Dias, executive secretary of the convention on biological diversity, acknowledged the potential environmental and socioeconomic effects of the Suez expansion, and asked Egypt to implement an environmental assessment.
“We trust that, as party to the Convention on Biological Diversity, Egypt will adhere to its obligations,” Dias told the Guardian.

This giant project will be the creation of a new Suez Canal parallel to the current channel of a total length of 72 kilometers (44.74 miles).
The new channel, part of a larger project to expand Suez port and shipping facilities, aims to raise Egypt’s international profile and establish it as a major trade hub.

Construction of the bypass, dubbed the “new Suez canal” by the Egyptian government, began in August.
It will allow two-way traffic for 45 miles of the canal’s 120-mile length, creating room for more ships, and potentially more revenue for cash-strapped Egypt.


The project has been warmly received by many Egyptians, who contributed 80% of the 64bn Egyptian pounds (£5.6bn) raised to build the new canal, after the government promised them a 12% annual yield on their investment.


Criticism of the project is seen as unpatriotic, with some local newspapers calling it “the project of the century” and comparing it to Egypt’s surprise attack on Israel in 1973 – one of the proudest moments in modern Egyptian history.
But it has come under fire from thousands of locals whose homes have been destroyed by the construction work.

Senior representatives for the Suez Canal Authority did not respond to two written requests for comment or answer their phones.

Questions asked about Volvo Ocean Race boat grounding

Team Vestas Wind informed Race Control at 1510 UTC (Nov. 29, 2014; Day 11)
that their boat was grounded on the Cargados Carajos Shoals,
Mauritius, in the Indian Ocean

From SailingScuttleButt

Team Vestas Wind may likely have concluded their Volvo Ocean Race campaign when their boat was grounded on the Cargados Carajos Shoals in the Indian Ocean on Saturday night, November 29. With both rudders broken and water ingress into the stern compartment, it was a grim moment for skipper Chris Nicholson and his team.

Sitting high on the reef, the crew waited until daylight, then stepped off the boat onto the reef, later to be transferred to a local rescue boat.
Now they will stay on nearby Íle du Sud today (Nov. 30), with plans to return to the boat on Monday to remove gear and travel on Tuesday to Mauritius (Dec. 2).

Two questions are being asked.
Where is Cargados Carajos Shoals and how can a professional team have this kind of accident?

As to why Vestas Wind ran aground, Vestas Chief Marketing Officer Morten Albæk is delaying comment.
“The root cause of the accident is now under investigation. (However) we obviously hope to stay in the race.”
A team led by the Vestas shore crew is now en route to Mauritius to further assess the damage to the boat.

Abu Dhabi Ocean Racing skipper Ian Walker was not surprised by the incident.
“When we went past there we actually said how easy it would be to hit it at night. Fortunately we went through there in the daylight. It is very difficult to see it with the electronic charts, and of course at night you wouldn’t see it at all.”

Team Alvimedica, which had been near Vestas Wind at the time of the incident, was equally concerned about safely navigating through the area.

“We had been talking about these reefs for some time, so we were already pretty nervous about it,” noted Team Alvimedica navigator Will Oxley in front of Adrena software screen
(see video)

Dongfeng Race Team reporter Yann Riou notes how they also had the Cargados Carajos Shoals directly in their path.
“Skipper Charles Caudrelier had noticed this archipelago a few days earlier, but it’s worth noting that it’s actually pretty hard to find. In fact, to see it on our electronic charts, you have to zoom right in on top of it. But how and why would you zoom into it if you don’t know it’s there in the first place? So whilst we don’t know exactly what happened on Vestas, we can imagine how it happened.”

Who bothers to "zoom in" when you are in the middle of the ocean?

After analyzing the early information from afar, marine industry consultant and professional navigator Campbell Field provides his opinion on the incident…
“Since Vestas Wind grounding there has been a huge amount of speculation and opinion as to how this happened, or who is to blame.

“It’s terrible for them, and terrible for the fleet and the race,”
says Dongfeng skipper Charles Caudrelier.
“We are offshore in the middle of nowhere, and on the chart, if you don’t go on the maximum zoom you can’t see anything.”
“There are shallow spots, and plenty 200m deeper - I’m not surprised you can miss them,” he adds.
“When I was looking at the navigation a few days ago, checking these things, it took a long time for me to find them.”
see VolvoOceanRace news

“I don’t know 100% about other software packages, but Expedition routing can route freely (i.e. with no obstacles) or can be constrained by charts, or your own marks, or your own prohibited zones. Plenty of optimal route outputs run where you would have to put the wheels down.
Ultimately, it is the user who defines how the routing output is run and results used.
“The point I’m putting forward here is that software does not make someone a navigator. First you must be a navigator, and then know and understand the strengths and limitations of the tools you have.
“When this is explained to a lot of people I meet, it is usually met with confused stares. The number of software jockeys (promoting themselves navigators) in yacht racing I have come across, who expect the answers to fall out of their computer, is astounding. Take the deck screen away from them and they couldn’t get out of the marina or find the top mark efficiently if their life depended on it.
“Vestas Wind navigator Wouter Verbraak is one of the best, and firmly falls into the category of a superb yachtsman and navigator. He is one who understands the strengths and limitations of digital tools more than most will ever do. And one of the nicest guys in the sport to boot.
“Mistakes happen. Just glad they are all safe and uninjured.”

Netscape cofounder Jim Clark may have just built one of the fastest yachts in the World



Netscape cofounder Jim Clark is no stranger to the high seas.
The 70-year-old serial entrepreneur — who's now worth $1.4 billion after investments in Apple, Facebook, and Twitter — owns two massive super yachts that he uses to compete in long-distance races.
However it's his brand-new boat, named "Comanche," that's grabbed the attention of the yachting world.
Comanche is a 100-foot monohull sailboat that can reach speeds of up to 40 mph.
According to CNN, it took Clark's team a year to finish it.
The tech billionaire told CNN that the primary goal is for Comanche "to be a record breaker" and "go really, really fast."
The yacht will get its first chance with an upcoming race that takes competitors 630 nautical miles from Sydney, Australia to Hobart, the capital of Tasmania.
It will be the first outing for Comanche.
"I wish Sydney-Hobart wasn't the first race, in fact you couldn't choose a worst race for our first race. It's like we've gone straight from the gym to the heavyweightchampionship of the world," Ken Read, Comanche's skipper, said to CNN.
"And it could end up like an F1 car blowing its engine on its first outing on the track."
Comanche and its 22-person crew have already set sail for Australia, where they will prepare for the Hobart race, which usually starts just after Christmas.Clark's other boat, the 295-foot "Athena," is currently for sale for $75 million.
