Zero declination and atmospheric pressure data as indicators of the timing of coral spawning test

This dataset combines four types of data: coral spawning, synodic lunar rhythm, sidereal lunar rhythm, and atmospheric pressure. The dates of the synodic and sidereal rhythms are for the periods of the coral spawning data recorded at Kochi, Japan in 2006-2009 and at Lizard Island, Great Barrier Reef, Australia in 1999-2001, and the atmospheric pressure data (2000-2016). The synodic lunar rhythm data is for the dates of the third (last) quarter and full moons. The sidereal lunar rhythm data records the dates of zero declinations i.e. when the moon passes over the equator as it moves between hemispheres.
