neap tide
Neap tides occur when the sun, earth, and moon form a right angle and the gravitational pull of the sun counteracts the pull of the moon.

neap tide

 (nēp)
n.
A tide that occurs when the difference between high and low tide is least. Neap tide comes twice a month, in the first and third quarters of the moon.

[Middle English neep, from Old English nēp(flōd), neap (tide).]

(Physical Geography) either of the two tides that occur at the first or last quarter of the moon when the tide-generating forces of the sun and moon oppose each other and produce the smallest rise and fall in tidal level. Compare spring tide1

neap tide

(nēp)
A tide in which the difference between high and low tide is the least. Neap tides occur twice a month when the sun and moon are at right angles to the Earth. When this is the case, their total gravitational pull on the Earth's water is weakened because it comes from two different directions. Compare spring tide. See more at tide.

In several geographical regions where the nocturnal Hs occur only in some tide periods other than the spring tide period, larval release synchrony in decapods is centered around the neap tide period (around lunar quadrature) or some later before the spring tide period (Christy 1978, Paula 1989, Queiroga et al.
