how deep is the twilight zone in the ocean
Mesopelagic zone The mesopelagic (Greek μέσον, middle) (also known as the middle pelagic or twilight zone) is that part of the pelagic zone that extends from a depth of 200 to 1000 metres (~660 to 3300 feet)[1] below the ocean surface. It lies between the photic epipelagic above and the aphotic bathypelagic below, where there is no light at all.
Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
