What are the tidal extremes known as during neap tides?

During neap tides, tidal extremes are indeed minimal. This phenomenon occurs when the sun and moon are positioned at right angles relative to the Earth. As a result, their gravitational pulls counteract each other, leading to lower tidal ranges. The high tides are not as high, and the low tides are not as low compared to normal tidal conditions.

Understanding neap tides is essential in hydrographic surveying as they can affect water levels and subsequently impact measurements, navigation, and marine operations. The reduced tidal range during neap tides is critical for ensuring safety and accuracy in these undertakings.

Other options regarding significantly increased tidal extremes and universal tidal extremes do not accurately reflect the nature of neap tides, which are characterized by their lesser tidal changes. The idea that neap tides cause no significant effect misunderstands their impact; while they do not create extreme highs and lows, they still influence the overall tidal cycle and conditions in aquatic environments.
