This zone is divided further into three subzones. Thus, they have very small wave slopes, and you might not even notice it in the deep ocean, because the normal wind-waves would catch your attention instead. The area of the open ocean where sunlight shines through the water is called the photic zone. The shifting plates may collide (converge), move away (diverge) or slide past (transform) each other.

Characteristics of Marine Life Common Adaptations of Aquatic Animals to Living in the Ocean. The strongest level of light is strongest at the ocean's surface and it decreases as you dive down to a deeper depth. Many of the organisms that we associate with marine ecosystems, such as whales, dolphins, octopi, and sharks, live in the open ocean. The most productive waters in the world are upwelling zones, such as those of the west coast of South America. Though these zones contain an abundance of ocean life because sunlight is available for photosynthesis, they make up only a small fraction of the ocean biome. Most people familiar with the oceans know about life only in the intertidal zone, where the water meets land, and the epipelagic zone, the upper sunlit zone of the open ocean. The demersal zone is everything in the ocean near the sea floor or the coast. 2. At the surface of the ocean, the euphotic zone, the ecosystem receives plenty of light and oxygen, is fairly warm, and supports many photosynthetic organisms.

The top layer is the euphotic and this is where the water is very shallow. Nutrient concentrations are low in most areas of the open ocean, and as a result this great expanse of water contains only a small percentage of all marine organisms. Sept. 24, 2020. The ocean is also divided into zones according to how much sunlight they receive. This is due in part to currents, waves, atmospheric pressure differences, and variations in gravity. The pelagic zone includes all open ocean regions, and can be divided into further regions categorized by depth and light abundance. Ocean Habitat From outer space Earth looks like an awesome blue marble. The sunlit zone is where photosynthesis takes place. SeaWiFS; … Most life in the open ocean is found in the photic zone. The open ocean has always played a vital role in the culture, subsistence, and economic well-being of Hawai‘i’s inhabitants. Archaea. Separated into epipelagic, mesopelagic, bathypelagic, abyssopelagic and hadopelagic subzones, areas in the pelagic zone are distinguished … The open ocean, is part of the marine biome, and is found all over the world.
