On the Beaches of the North and Baltic Seas
摘要
The North and Baltic Seas have great ecological and touristic significance. With their resorts and islands, they attract hundreds of thousands of vacationers. In addition to relaxation, stimulating climate, good air, beaches and dunes, the coasts offer all sorts of natural experiences—mostly during the day. But even at night, one can experience numerous colorful phenomena. From the breathtaking, blue bioluminescence of the sea to the color spectacle in UV light: red, yellow, blue, and orange glowing algae, blue fluorescent crab shells and jellyfish. In daylight, your children might enjoy a handmade, small sand avalanche or you might enjoy finding chalk fossils, pieces of amber, and lucky stones.
