Yvan Bourgnon completes remarkable round-the-world challenge alone on a beach catamaran


He started his grueling journey in October 2013, he capsized in the Atlantic, crashed his boat on rocks in Sri Lanka and experienced a terrifying near-miss with a cargo ship, but Yvan Bourgnon finally completed his round-the-world solo effort.

Making his journey even more impressive is the fact that the Swiss sailor circumnavigated the globe in a tiny 6.2 metre, cabin-less beach catamaran that had no GPS and computer-aided navigation.

Using the stars, a sextant and maps the adventurer took 20 months to complete his 50 000 kilometre challenge which included multiple stop overs for rest and repairs.

Two days after his arrival, his brother Laurent Bourgnon has been lost in a diving accident in French Polynesia.
He was reported missing on the 25th June and despite a comprehensive search no trace has been found.
Laurent was best known for his victories in the 1994 and 1998 in the solo Route du Rhum onboard the ORMA trimaran Primagaz.

NOAA WeatherView


NOAA weatherView is a new tool designed by the NOAA Visualization Lab to provide an interactive experience with NOAA weather models : lets you display wind, temperature, precipitation and other models to see weather patterns around the globe.

 The NOAA gives us the example of Typhoon Soudelor, which passed over Taiwan yesterday.

All of these data are also available from the NOAA Operational Model Archive and Distribution System built by NOAA National Centers for Environmental Information - Climate.

Image of the week : the dark side and the bright side of the moon


From NASA

A NASA camera aboard the Deep Space Climate Observatory (DSCOVR) has captured a unique view of the Moon as it passed between the spacecraft and Earth.
A series of test images shows the fully illuminated “dark side” of the Moon that is not visible from Earth.


The images were acquired by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope on the DSCOVR satellite, which orbits about 1.6 million kilometers (1 million miles) from Earth.
EPIC maintains a constant view of the fully illuminated Earth as it rotates, providing daily scientific observations of ozone, vegetation, cloud height, and airborne aerosols.
About twice a year the camera will capture images of the Moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the Moon.
The images shown above and in the movie below were taken over the course of five hours on July 16, 2015.
The North Pole is toward the upper left, reflecting the orbital tilt of Earth from the vantage point of the spacecraft.


The far side of the Moon was first observed in 1959, when the Soviet Luna 3 spacecraft returned the first images.
Since then, several missions by NASA and other space agencies have imaged the lunar far side.
(For instance, NASA’s Deep Impact spacecraft captured a similar view of Earth and the Moon from a distance of 31 million miles in 2008.)
The same side of the Moon always faces an earthbound observer because the Moon’s orbital period is the same as its rotation around its axis.
EPIC’s natural-color images of Earth are generated by combining three separate monochrome exposures taken by the camera in quick succession.
EPIC takes a series of 10 images using different spectral filters—from ultraviolet to near infrared—to produce a variety of science products.
The red, green, and blue channel images are used in these color images.
But combining three images that are taken about 30 seconds apart produces a slight but noticeable camera artifact on the edges of the Moon.
Because the Moon moved in relation to Earth between the time the first (red) and last (green) exposures were made, a thin green offset (about 7–8 pixels) appears on the right side when the three exposures are combined.
This movement also produces a slight red and blue offset on the left side of the unaltered images.

The lunar far side lacks the large, dark, basaltic plains, or maria, that are so prominent on the Earth-facing side.
The largest far side features are Mare Moscoviense (Sea of Moscow) in the upper left and Tsiolkovskiy crater in the lower left.
Situated at a stable orbit between the Sun and Earth, DSCOVR’s primary mission is to monitor the solar wind for space weather forecasters at the National Oceanic and Atmospheric Administration (NOAA).
Its secondary mission is to provide daily color views of our planet as it rotates through the day.

Egypt shows off $8billion Suez Canal expansion that the world may not need

 Map of the New Suez Canal compared with the Old Canal

It will save time for ships & Yachts in transit through Suez canal up to 10 hours in addition will allow ships with 66 feet draft to transit and up to 97 ships per day transit from both ways Suez and port said the total Suez canal length is 193 KM , the main entrance of Suez canal from Mediterranean sea is port said and from Red sea is port tawfik in the city of Suez .

From Bloomberg by Ahmed Feteha

The Suez Canal took 10 years to build and cost thousands of workers their lives.
When planners suggested three years for a second one, Egypt’s president balked.
“Not three years, just one,” he ordered.
Twelve months later, Abdel-Fattah El-Sisi is hosting a party to celebrate the biggest expansion of the canal since it first opened in 1869.
For the former army chief seeking to bolster his rule, the symbolism is impossible to miss.
Less clear are the economic benefits of what billboards in Cairo and New York’s Times Square dub “Egypt’s gift to the world,” which will raise capacity and shorten the time it takes to sail the 193-kilometer (120-mile) link between the Red Sea and the Mediterranean.
Thursday’s ceremony, to be attended by dignitaries from French President Francois Hollande to North Korea’s deputy leader Kim Yong Nam, comes amid sluggish global trade growth to which the canal’s fortunes are linked.
“From a shipping industry point of view, this initiative to expand the Suez canal was a bit of a surprise,” said Ralph Leszczynski, Singapore-based head of research at Genoese shipbroker Banchero Costa & Co.
“There was no pressing need or requests for this as far as I’m aware.”
Suez has yet to fully recover since the global financial crisis caused shipping to plummet in 2009. Though total tonnage has increased, the number of vessels using the canal remains 20 percent below its 2008 level and just 2 percent higher than a decade ago, data compiled by Bloomberg show.
Rather than a bottleneck, analysts say those statistics reflect slower global trade growth, which the International Monetary Fund expects to average 3.4 percent in the period 2007-2016, compared with 7 percent over the previous decade.
The Baltic Dry Index, which measures rates for shipping iron ore, coal and grain and is viewed as a bellwether for the global economy, slumped to a record low 509 points in February.
It remains about 90 percent below its all-time high of 11,793 reached in 2008.

The iconic project in Egypt is almost coming to an end.
On Saturday, the very first three vessels sailed through the new Suez Canal.
In the first week of August the new canal will be officially inaugurated.
A total of 200 million m³ was dredged in less than one year, which makes this iconic work the largest cutter project eve.

Lacking Details

“At the moment, speed is not a key factor for container shipping, the shipping sector which most utilizes the canal,” said Michelle Berman, the head of operational risk at BMI Research, a unit of Fitch Group.
A bigger issue is a “surplus of ships” relative to demand, with ever-larger vessels built for the Asia-Europe route compounding the problem, she said.
The government hasn’t made public viability studies to show how it will gain a return on its 64 billion Egyptian pound ($8.2 billion) investment.
The expansion will meet future demand, with traffic expected to double to 97 vessels a day by 2023, said Mohab Mameesh, head of the Suez Canal Authority.
“By creating a second lane of the canal we are able to reduce waiting times, which reduces fuel expenditures and costs, with no increase in our toll fees,” he said in an e-mailed response to questions.
Global trade volume would need to rise by around 9 percent a year for Suez to reach its traffic goal, Capital Economics said in a report on Monday, describing the target as “unlikely to say the least.”

New Suez Canal had a trial run today.
Vessels sailing the new canal are nicely visible on MarineTraffic.

Canal Distraction

That hasn’t stopped El-Sisi and his government from talking up the new canal amid political challenges to its rule.
Hundreds of Egyptians, most of them supporters of the deposed Muslim Brotherhood, have been killed and thousands imprisoned since El-Sisi, as army chief, pushed his Islamist predecessor from office in 2013 after mass protests.
El-Sisi was elected president last year.
The political turmoil has polarized Egyptians
El-Sisi supporters say it saved the country from the deadly strife affecting much of the Middle East, while opponents criticize the government’s human rights record and what they regard as brutality used to restore stability.

French Connection

Thursday’s party, with an estimated price tag of $30 million, is a chance for the government to send a more positive message by harking back to the events marking the canal’s 1869 completion.
French empress Eugenie attended -- her husband Napoleon III was deposed a year later -- and a performance of Giuseppe Verdi’s ’Rigoletto’ opened Cairo’s new opera house.
The canal has since transformed global trade.
About 8 percent of the world’s cargo now passes through the canal, according to the Suez Canal Authority. Traveling from Singapore to New York through Suez reduces the distance by 19 percent compared with the route via the Pacific and the Panama Canal.
From the Persian Gulf to Rotterdam, Suez saves 42 percent by removing the detour around the Cape of Good Hope.
“Even without any improvements, the canal would always be attractive,” said Neil Atkinson, head of analysis at Lloyd’s List Intelligence.

The finish of the Suez Canal project is in sight.
The dredging of more than a million cubic meters of sand a day is unprecedented.
And this assignment has also pushed back the boundaries in terms of speed, and the deployment of equipment and manpower.

Wider, Deeper

The second canal -- actually a new 35-kilometer channel and 37 kilometers of widening and deepening of the original -- allows two-way traffic and reduces transit time to 11 hours from 18, according to the canal operator.
The expansion won’t allow larger vessels to use the route.
New ports and logistical services are expected to follow, and the project includes six tunnels under the canal.
The authority expects revenue to grow to more than $13 billion by 2023, up from $5.5 billion in 2014.
“‘Build it and they will come’ is not enough,” said Simon Kitchen, a strategist with Cairo-Based investment bank EFG-Hermes, adding that companies will require incentives to build factories and other facilities.
“The government needs to give ships a reason to sail through the canal,” he said.
Others are more positive.
Egypt’s economy grew at over four percent in the nine months to March for the first time since 2010, mainly due to infrastructure spending related to the canal upgrade, according to investment bank Pharos Holding for Financial Investments.

 Actual dredged quantities according to progress of works : 258.8 million cubic meters
Duration of execution : 12 months, including mobilization of dredgers
Consortium's first dredger to be employed in the project : Dredger "Al-Marifaa" on Nov. 5th,2014
Quantities of Dry excavation works : 250 million cubic meters
Highest daily rate of dredged quantities was achieved by dredger "Ibn Batouta" on April 6th,2015    230,000 cubic meters
Highest daily output of dredged quantities was achieved on May 31th ,2015 : 1.73 million cubic meters
Number of dredgers employed in the project : 45 dredgers
Number of sedimentation basins : 20 basins

SC2, Suez Canal, (Edition 1, dated 15th July 2015)
Following the establishment of the New Suez Canal, the Suez Canal Authority along with Egyptian Navy Hydrographic Department have produced two charts to help mariners sail safely in the New Suez Canal.
Accordingly, sailing in the Suez Canal and vessel inspection will be performed only through charts SC1 and SC2 and no vessel will pass Suez Canal without the above charts being on board starting 06 August 2015.

Saving Money

A shorter transit may save up to 4 percent of journey costs depending on the length, the Napoli-based economic research center SRM estimates.

 Shipping times : Northeast passage vs Suez Canal
 Arctic shipping routes unlikely to be 'Suez of the north'
The North Sea route has become free of ice, but the navigation season is still just two-four months 

The project “was a necessity to maintain the attractiveness of the Suez Canal,” said Michael Storgaard, a spokesman for Maersk Line, the world’s biggest container shipping company.
Even so, it’s too early to say whether Maersk will route more vessels through Suez, he said.
Still, any future economic payoff is trumped by the political implications for the government from building confidence in El-Sisi’s leadership, according to Amr Adly, a scholar with the Carnegie Middle East Center in Beirut.
“El-Sisi is trying to gain legitimacy through his government’s achievements,” Adly said.
His thinking is that Suez “shows the government can deliver, it can commit to something and get it done,” he said.

Stop burning fossil fuels now: there is no CO2 'technofix', scientists warn

 No 'Plan B' for oceans, says study
 “The chemical echo of this century’s CO2 pollution will reverberate for thousands of years,” said the report’s co-author, Hans Joachim Schellnhuber

From The Guardian by Tim Radford

Researchers have demonstrated that even if a geoengineering solution to CO2 emissions could be found, it wouldn’t be enough to save the oceans

German researchers have demonstrated once again that the best way to limit climate change is to stop burning fossil fuels now.
In a “thought experiment” they tried another option: the future dramatic removal of huge volumes of carbon dioxide from the atmosphere.
This would, they concluded, return the atmosphere to the greenhouse gas concentrations that existed for most of human history – but it wouldn’t save the oceans.
That is, the oceans would stay warmer, and more acidic, for thousands of years, and the consequences for marine life could be catastrophic.
The research, published in Nature Climate Change today delivers yet another demonstration that there is so far no feasible “technofix” that would allow humans to go on mining and drilling for coal, oil and gas (known as the “business as usual” scenario), and then geoengineer a solution when climate change becomes calamitous.

 Atmospheric concentrations of important long-lived greenhouse gases over the last 2,000 years. Increases since about 1750 are attributed to human activities in the industrial era, via Co2now.org

Sabine Mathesius (of the Helmholtz Centre for Ocean Research in Kiel and the Potsdam Institute for Climate Impact Research) and colleagues decided to model what could be done with an as-yet-unproven technology called carbon dioxide removal.
One example would be to grow huge numbers of trees, burn them, trap the carbon dioxide, compress it and bury it somewhere.
Nobody knows if this can be done, but Dr Mathesius and her fellow scientists didn’t worry about that.
They calculated that it might plausibly be possible to remove carbon dioxide from the atmosphere at the rate of 90bn tons a year.
This is twice what is spilled into the air from factory chimneys and motor exhausts right now.
The scientists hypothesized a world that went on burning fossil fuels at an accelerating rate – and then adopted an as-yet-unproven high technology carbon dioxide removal technique.
“Interestingly, it turns out that after ‘business as usual’ until 2150, even taking such enormous amounts of CO2 from the atmosphere wouldn’t help the deep ocean that much - after the acidified water has been transported by large-scale ocean circulation to great depths, it is out of reach for many centuries, no matter how much CO2 is removed from the atmosphere,” said a co-author, Ken Caldeira, who is normally based at the Carnegie Institution in the US.


The oceans cover 70% of the globe.
By 2500, ocean surface temperatures would have increased by 5C and the chemistry of the ocean waters would have shifted towards levels of acidity that would make it difficult for fish and shellfish to flourish.
Warmer waters hold less dissolved oxygen.
Ocean currents, too, would probably change.

 Ocean acidification

But while change happens in the atmosphere over tens of years, change in the ocean surface takes centuries, and in the deep oceans, millennia.
So even if atmospheric temperatures were restored to pre-Industrial Revolution levels, the oceans would continue to experience climatic catastrophe.
“In the deep ocean, the chemical echo of this century’s CO2 pollution will reverberate for thousands of years,” said co-author Hans Joachim Schellnhuber, who directs the Potsdam Institute.
“If we do not implement emissions reductions measures in line with the 2C target in time, we will not be able to preserve ocean life as we know it.”
