Since 1910, this statue has warned Parisians about flooding
If the zouave of the Alma bridge gets his feet wet, Paris knows to start worrying
From a young age, Frank was fascinated by maps and atlases, and the stories they contained. Finding his birthplace on the map in the endpapers of Tolkien's Lord of the Rings only increased his interest in the mystery and message of maps.
While pursuing a career in journalism, Frank started a blog called Strange Maps, as a repository for the weird and wonderful cartography he found hidden in books, posing as everyday objects and (of course) floating around the Internet.
"Each map tells a story, but the stories told by your standard atlas for school or reference are limited and literal: they show only the most practical side of the world, its geography and its political divisions. Strange Maps aims to collect and comment on maps that do everything but that - maps that show the world from a different angle".
A remit that wide allows for a steady, varied diet of maps: Frank has been writing about strange maps since 2006, published a book on the subject in 2009 and joined Big Think in 2010. Readers send in new material daily, and he keeps bumping in to cartography that is delightfully obscure, amazingly beautiful, shockingly partisan, and more.
This Monday, winter floods in Paris finally peaked, with the Seine river reaching a level of 5.84 metres - 4 metres more than normal. Those measurements come from the official hydrometric scale on the Austerlitz bridge. Most Parisians prefer another yardstick for the water level: the zouave of the Alma bridge.
December and January have been the second-rainiest two-month period since 1900, when records began in France. As a result, homes, shops and roads in Paris close to the river have been inundated. Service on a train line under the river has been halted. River traffic is suspended. The Louvre, the Musée d'Orsay and the Orangerie are all ready to move works to higher locations if the Seine rises any further. Rats, flushed out of their subterranean dens, are invading the city at ground level, also looking for dry shelter.
The Seine often rises in winter. But Parisians know to start worrying about the Seine only when the zouave gets his feet wet. Over the past week, they anxiously watched the water creep up along the statue's puffy trousers and bended knees. However, as the river crested on Monday, the stone soldier managed to keep his waist dry.
So, not quite as bad as the Great Flood of 1910. Back then, the zouave disappeared almost up to his neck in water. Ever since that 'Flood of the Century', the 5.2 metre high statue has been Paris's favourite way to gauge the threat posed by the frequently overflowing Seine.
The zouave is the last of four statues that flanked the Pont de l'Alma, which crosses the Seine in the centre of Paris. The original bridge was inaugurated in 1856 by French emperor Napoleon III.
The Battle of Alma was the first major engagement of the Crimean War (1853-1856), in which Franco-British forces resoundingly defeated the Russians. Celebrating the victory, 'Alma' became a popular girl's name in Britain – and the name of a bridge in Paris.
In recognition of the four French army corps which fought at Alma, statues of a ranger and artilleryman were put up in front of the pillars on the downstream side of the bridge, and a grenadier and a zouave on the upstream side.
Zouaves were a class of French light infantry, in service from 1830 to 1962. They were named after the Zwāwa group of Berber tribes in North Africa who had earned a martial reputation, fighting for local rulers during the Ottoman period.
Despite the name, France's zouave regiments consisted mainly of European recruits, although they retained distinctive 'oriental' traditions in titles, marching styles and dress. Units often sported fezzes or turbans, colourful uniforms and baggy trousers.
Their exotism enhanced their popularity. Other countries also created zouave regiments, including the Papal States, Poland, Spain, Brazil and the U.S., where zouave units fought on both sides of the Civil War.
The zouave of the Alma bridge is dressed in typical uniform, including fez and baggy trousers. He leans on his rifle, looking towards his right.
During the Great Flood of 1910, which turned Paris into Venice and its boulevards into canals, the eight-tonne statue's detailed outfit – trousers, belt and jacket, to name a few – became a popular way to measure the rise of the river. In 1910, with river levels at their peak and the zouave nearly getting his shoulders wet, the hydrometric scale hit 8.26 metres.
In the early 1970s, the narrow stone bridge was replaced with a wider steel one. Three statues were removed, remaining on display in other parts of the country. Because of his place in Parisian folklore, the zouave was permitted to stay – but moved to the other side of the bridge. He was re-installed at a different height: either 10 cm higher or lower (nobody seems to know which it is).
In the six decades before the bridge's renovation, the zouave got wet feet three times (in 1924, 1945 and 1955) and eight times in the four decades since (in 1982, 1988, 1995, 1999, 2001, 2013, 2016 and 2018). The acceleration may not simply be a result of a change in elevation, but could have something to do with climate change as well.
Keeping in mind the changes in his position and elevation, this map shows how the zouave holds up as a measurement for river flooding.
There are five levels of flood readiness in Paris: situation normal, level 1 (vigilance), level 2 (state of alert), level 3 (pre-mobilisation) and level 4 (crisis). Each corresponds more or less to an elevation of the Seine river, as indicated by the map. Some specific steps to be taken include:
- At 3.20 metres, the Berges de Seine footpath is closed
- At 3.45 metres, shutdown of traffic on the riverbanks will commence
- At 4.30 metres, all shipping and port activity is suspended
- At 5.50 metres, subterranean spaces start to flood
- At 6.00 metres, the RER C railway tunnel starts to flood
- At 6.10 metres, total closure of riverbank roads
- At 7.30 metres, water enters the upstream 12th and 13th arrondissements in Paris. Water flows into the 4th, 7th, 15th and 16th arrondissements.
The map also shows the height achieved by the Seine in some of the flood years mentioned earlier:
- 5.21 metres in 2001, halfway up the zouave's boots
- 6.18 metres in 1982 and 6.20 meters in 1958, almost at his knee
- 6.85 metres in 1945, halfway up his thigh
- 7.12 metres in 1955, nearly at his waist
- 7.30 metres in 1924, navel-height, and
- 8.62 metres in 1910, at his shoulders
One even higher flood predates the statue of the zouave by almost two centuries: the flood of 1658, which reached a height of 8.96 metres.
The zouave is now firmly entrenched in Parisian folklore. He's been mentioned in song by Georges Brassens and other French chansonniers, and he's lent his name to a novel (Le Zouave du pont de l'Alma by Roger Bordier, 2001). Inevitably, he now also has his own twitter account. Next time you're in Paris, check whether he's keeping his feet dry.

If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.
- A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
- It's part of a project intending to sequence the genome of every vertebrate in the world.
- Conservationists interested in the Canadian lynx have a new tool to work with.
If you want to know what makes a Canadian lynx a Canadian lynx, I can now—as of this month—point you directly to the DNA of a Canadian lynx, and say, "That's what makes a lynx a lynx." The genome was sequenced by a team at UMass Amherst, and it's one of 15 animals whose genomes have been sequenced by the Vertebrate Genomes Project, whose stated goal is to sequence the genome of all 66,000 vertebrate species in the world.
Sequencing the genome of a particular species of an animal is important in terms of preserving genetic diversity. Future generations don't necessarily have to worry about our memory of the Canadian Lynx warping the way hearsay warped perception a long time ago.

It is easy to see how one can look at 66,000 genomic sequences stored away as being the analogous equivalent of the Svalbard Global Seed Vault. It is a potential tool for future conservationists.
But what are the practicalities of sequencing the genome of a lynx beyond engaging with broad bioethical questions? As the animal's habitat shrinks and Earth warms, the Canadian lynx is demonstrating less genetic diversity. Cross-breeding with bobcats in some portions of the lynx's habitat also represents a challenge to the lynx's genetic makeup. The two themselves are also linked: warming climates could drive Canadian lynxes to cross-breed with bobcats.
John Organ, chief of the U.S. Geological Survey's Cooperative Fish and Wildlife units, said to MassLive that the results of the sequencing "can help us look at land conservation strategies to help maintain lynx on the landscape."
What does DNA have to do with land conservation strategies? Consider the fact that the food found in a landscape, the toxins found in a landscape, or the exposure to drugs can have an impact on genetic activity. That potential change can be transmitted down the generative line. If you know exactly how a lynx's DNA is impacted by something, then the environment they occupy can be fine-tuned to meet the needs of the lynx and any other creature that happens to inhabit that particular portion of the earth.
Given that the Trump administration is considering withdrawing protection for the Canadian lynx, a move that caught scientists by surprise, it is worth having as much information on hand as possible for those who have an interest in preserving the health of this creature—all the way down to the building blocks of a lynx's life.
