Final answer:
A standing wave in a semienclosed basin in the North Atlantic would generally feature nodes, antinodes, and an amphidromic point, with the cotidal lines moving in a counterclockwise direction due to the Coriolis effect, contrary to the clockwise direction stated in the question.
Step-by-step explanation:
A standing wave in the context of a semienclosed basin in the North Atlantic has several characteristics. A Kelvin wave is a type of coastal wave or alongshore wave that travels without change in form. An amphidromic point is a point in an ocean or sea basin around which the cotidal lines rotate (lines of equal tidal phase). Standing waves have nodes, which are points of no motion, and antinodes, which are points of maximum motion of the wave. The crest or antinode oscillates between maximum and minimum displacements, due to the cosine term in the wave equation, which oscillates between +1 and -1. The node to antinode distance corresponds to a quarter of the wavelength of the wave.
Regarding the behavior of the crest (antinode) and cotidal lines movement, in the Northern Hemisphere, due to the Coriolis effect, they tend to move in a counterclockwise direction around the amphidromic point—directly opposite of what is described in the question as moving in a clockwise direction.
