rocky-shore denudation; sea desertification
Ecological term for the disappearance of useful coastal seaweeds, often due to environmental factors such as rising water temperatures or overgrazing by sea urchins.
Rising seawater temperatures are pointed to as a cause of rocky-shore denudation.
In this sea area, sea desertification has become severe, and seaweed beds have decreased drastically.
Compound of 磯 (いそ, 'rocky shore') and 焼け (やけ, 'burning' or 'scorching'), referring to the barren, scorched appearance of the shore when seaweed disappears.
