Morphology
upwelling = upwell (semi-transparent) = up + well + ing
Morphologically transparent as 'up' + 'well' + '-ing', but the specialized oceanographic meaning (deep, cold, nutrient-rich water rising) requires domain knowledge beyond simple composition.
Etymology
Upwelling comes from up + well, where well means 'to rise' or 'spring'. In the ocean, deep cold water 'wells up' to the surface and brings nutrients that feed small sea life, so an upwelling explains that upward movement and its effect on marine life.
