French towns brace for giant tidal surge

In Northern France on Saturday a full moon (and solar eclipse) created an ocean surge not seen since 1997.

Towns on France's North Atlantic coast braced for their first giant tide of the millennium on Saturday as the full moon and this week's solar eclipse combined to create an ocean surge not seen since 1997.

At the picturesque Mont Saint Michel island where some of the biggest tides in the world occur, visitors gathered to watch the tide disappear out of sight, exposing areas of beach and rock visible only every 18 years. The next peak tide is not due until 2033.

France's National Hydrographic Service was expecting to measure more than 14 meters (15.3 yards) between low and high water around the famous Abbey-topped rock off France's north-west coast. Average tides in the area measure 8.7 meters.

Saturday morning's high tide was also close to peak levels as the sea rushed in from over 13 kilometers (8 miles) out, but calm weather has meant that some coastal flood preparations looked set to prove unnecessary and made the phenomenon less spectacular than some had hoped.

"For the 'tide of the century' I am a bit disappointed," said tourist Jean-Bernard Delamarche in Saint Malo further west along the coast which also has big tides. "We came one year, we were staying at the hotel Ibis and we could not get out of the hotel because the street was flooded. But it's true that it is impressive."

"It's almost more spectacular at low tide in the end because you will be able to walk kilometers and see some little secret beaches that will only be revealed at this moment," said Laurence Bozzuffi, director of the Saint-Malo tourism office.

The lowest tide measured from the port of Granville up the coast from Mont Saint Michel was due at 3:16 pm local time (1416 GMT) with the highest at 8:10 pm.

The largest tidal ranges in the world occur in Canada at the Bay of Fundy and Ungava Bay where, according to the Canadian Hydrographic service, tides can reach 17 meters in height.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
