Seaweed from the Iroise Sea 1






You will discover seaweeds at low tide. But then, the sea goes up again.
Caution: for 6 hours the sea goes up at different speeds !




Whether it rises or falls, the tide always respects the rule of twelfths.
Remember: 1-2-3-3-2-1

1st hour : 1 twelfth, 2nd hour : 2 twelfths,
3rd and 4th hour : 3 twelths,
5th hour : 2 twelfths, 6th hour : 1 twelfth
