One of the mysteries of the English language finally explained.
1The process or state of emerging from or being out of water after being submerged.
- ‘Organisms that live higher on the shore experience larger daily and seasonal fluctuations in microhabitat conditions, due to their greater exposure to terrestrial conditions during emersion.’
- ‘The restructuring of the membrane bilayer, which may occur during the tidal cycle, if body temperature fluctuates widely during emersion and immersion, represents a second energetic cost to intertidal species.’
- ‘Presumably, the increased chaperone need is induced by exaggerated gill protein denaturation in response to elevated body temperatures during emersion.’
- ‘Webster discussed the physiological significance of this mechanism of endocrine metabolic adaptation for C. pagurus, which may be repeatedly subjected to short-term emersion and hypoxia in the intertidal zone.’
- ‘In fact, as discussed later, metabolic processes may be especially active during periods of immersion, when access to oxygen and food is greater than under conditions of emersion.’
- 1.1Astronomy The reappearance of a celestial body after its eclipse or occultation.
- ‘The spectacular reappearance of the planet - emersion - should be plainly visible to the unaided eye.’
- ‘Such terminology may also be used for eclipses and occultations, along with their synonyms immersion and emersion.’
- ‘So at 3.45pm BST, we decided to pack up and go to our respective homes in order to observe the emersion of Venus if we could.’
Mid 17th century: from late Latin emersio(n-), from Latin emergere (see emerge).
