What can you tell me about tidal movements and currents off the coast of Copenhagen, Denmark?
<|assistant|>
Off the coast of Copenhagen, Denmark, there are two main tidal movements: the sextial and the semidiurnal. The sextial tidal movement is a single, powerful surge that happens every 12 hours and affects the deep sea. The semidiurnal tidal movement consists of two small surges that happen every day and affect shallow and coastal seas. Around the coast of Copenhagen, strong currents develop from the tides which can vary in speed, strength, and temperature depending on the season.
