WebSunlit Zone. The upper layer of the ocean is known as the sunlit, or euphotic, zone. Because water strongly absorbs light, sunlight penetrates only to depths of about 200 meters (656 feet). The twilight zone or the mesopelagic zone begins at 200 meters and extends downward to 1,000 meters, making up approximately 20% percent of the ocean’s total depth. It is generally a very dim region, but it does receive a sliver of sunlight at the midday point which is enough for photosynthesis to … Meer weergeven Aptly named for its position at the surface level, this sunlight zone, also called the surface zone or epipelagic zone, extends downward 200 meters or roughly 5% of the ocean’s … Meer weergeven The deep ocean—the third and final layer—extends from the 1,000 meter point to the ocean floor, regardless of how deep that is.

The euphotic zone average temperature ranges from 10°C-30°C, with the optimum around 20°C. The euphotic zone is also sometimes called the “productive zone” because of the amount of energy needed for photosynthesis to happen. thai airways ktm to sydney
