On This Day:
Saturday March 29, 2014 This is the 88th day of the year, with 277 days remaining in 2014. Fact of the Day: ocean zones Oceanographers divide the ocean into five zones for depth classification: epipelagic or sunlit zone (0-200 m), mesopelagic or twilight zone (200-1,000 m), bathypelagic or midnight zone (1,000-4,000 m), abyssal zone (4,000-6,000 m), and hadal zone (6,000-11,000 m). The epipelagic or sunlit zone is the top layer of the ocean, where enough sunlight penetrates for plants to carry on photosynthesis; the mesopelagic or twilight zone allows some light to penetrate, but not enough for plants to grow. No light penetrates the bathypelagic or midnight zone. In the abyssal zone the water is pitch black and almost freezing, and the pressure is immense. The hadal zone constitutes the deepest trenches of the ocean. Plants can live only in the epipelagic or sunlit zone, but animals can and do live in all the ocean's zones. Over 90% of marine species live on the ocean bottom.
