What is the climate in the ocean biome?
Marine biome experiences an average temperature of 39 degrees Fahrenheit (4 degrees Celsius). The ocean biome is naturally colder at the South Pole, but as you approach the equator, it becomes warmer because the sun rays strike the water surface directly.
What is the typical location of open ocean?
The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed. It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths.
What are the characteristics of the open ocean?
Characteristics of the Open Ocean. The open ocean is vast and variable. In addition to light changes, pressure and temperature change dramatically from the surface to the deep sea. Warmer waters in the sunlight zone are mixed by wind and waves, creating a surface layer of relatively consistent temperatures.
What is open ocean biomes?
The Pelagic zone or the Open Ocean is the ocean biome zone which is found in the open seas. On account of the climatic diversity found in these parts of the water, a wide variety of marine creatures are found in this ocean biome zone.
Does the open ocean have seasons?
Seasons change in the ocean much as they do on land. Spring brings new plants and baby animals, summer oceans glow with sparkly plankton lights, and autumn winds blow across the open water. In winter the humpback whales migrate to warmer waters, just as some land animals move to warmer climates.
What is the average temperature of the ocean?
The average temperature of the sea surface is about 20° C (68° F), but it ranges from more than 30° C (86° F) in warm tropical regions to less than 0°C at high latitudes. In most of the ocean, the water becomes colder with increasing depth.
What are 3 main zones of the open ocean?
There are three main ocean zones based on distance from shore. They are the intertidalzone, neriticzone, and oceaniczone.
Why is the open ocean unproductive?
In surface waters away from coastlines, generally there is plenty of sun but not enough nutrients. So most of the ocean surface is not very productive. The water is too deep for storms to stir up nutrients from the bottom and there isn't upwelling.
What are the main differences between the coastal ocean and the open ocean?
Even though the coast is just a small sliver of the ocean, it is the more productive of the two marine biomes. This means the coasts hold more marine biodiversity, which provides food for many animals, including humans. The open ocean stretches from the edges of the coast between the continents for hundreds of miles.
What type of biome is the ocean?
aquatic biome The aquatic biome is the largest of all the biomes, covering about 75 percent of Earth's surface. This biome is usually divided into two categories: freshwater and marine. Typically, freshwater habitats are less than 1 percent salt.
What is the environment of the ocean like?
Some habitats are shallow, sunny and warm. Others are deep, dark and cold. Plant and animal species are able to adapt to certain habitat conditions, including movement of water, amount of light, temperature, water pressure, nutrients, availability of food, and saltiness of water.
What is a warm ocean temperature?
Water Temperature of the Sea Equal to or Above 26°C (79°F) For swimming in this is considered very warm and would be enjoyed be all. With this temperature you can stay active in the water for extended periods of time without feeling uncomfortable.
What is the salinity of the open ocean?
33 to 37 grams The range of salinity observed in the open ocean is from 33 to 37 grams of salt per kilogram of seawater or psu.
What is the temperature of the oceanic zone?
41 to 39 °F This zone is often referred to as the "Twilight Zone" due to its scarce amount of light. Temperatures in the Mesopelagic zone range from 5 to 4 °C (41 to 39 °F). The pressure is higher here, it can be up to 1,470 pounds per square inch (10,100,000 Pa) and increases with depth.
Why coastal waters are more productive than the open ocean?
The proximity to land and its nutrient sources, the interception of sinking organic matter by the shallow seafloor, and the propensity for coastal upwelling all result in highly productive ecosystems.
Which part of the ocean is the most productive?
Although they occupy less than two percent of the oceans, the coastal upwelling areas in the eastern parts of the Pacific and Atlantic Ocean are among the biologically most productive marine areas worldwide.
Why coastal regions are more productive than the open ocean?
The proximity to land and its nutrient sources, the interception of sinking organic matter by the shallow seafloor, and the propensity for coastal upwelling all result in highly productive ecosystems.
What is the temperature in the ocean?
The average temperature of the sea surface is about 20° C (68° F), but it ranges from more than 30° C (86° F) in warm tropical regions to less than 0°C at high latitudes. In most of the ocean, the water becomes colder with increasing depth.
What is a tropical ocean biome?
Tropical oceans encircle Earth in an equatorial band between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). * The central portions of the Pacific and Atlantic Oceans and most of the Indian Ocean lie in the tropics.
What are the differences between habitats in the open ocean?
Marine habitats can be divided into coastal and open ocean habitats. Coastal habitats are found in the area that extends from as far as the tide comes in on the shoreline out to the edge of the continental shelf. Open ocean habitats are found in the deep ocean beyond the edge of the continental shelf.
Which oceans are warm?
Here are the oceans in order of their temperature:
- Indian Ocean. This ocean is bordered by Asia, Africa, and Australia and is the warmest in the world. …
- Pacific Ocean. The Pacific Ocean hosts many marine animals and provided 60% of the world's fish in 1996. …
- Atlantic Ocean. …
- Southern Ocean. …
- Arctic Ocean.

Where is the warmest ocean?
The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.
Which ocean is the saltiest?
the Atlantic Ocean Which ocean is the saltiest? Of the world's five ocean basins — Pacific, Atlantic, Indian, Southern and Arctic Oceans — the Atlantic Ocean has the highest salinity, says the National Weather Service. This is because salinity decreases near the equator and at both poles.
Who have higher salinity than open seas?
Explanation: Oceans have higher salinity than open seas.
What are the three open ocean zones?
There are three main ocean zones based on distance from shore. They are the intertidalzone, neriticzone, and oceaniczone.
What are the conditions of the oceanic zone?
Temperatures in the Mesopelagic zone range from 5 to 4 °C (41 to 39 °F). The pressure is higher here, it can be up to 1,470 pounds per square inch (10,100,000 Pa) and increases with depth. 54% of the ocean lies in the Bathypelagic (aphotic) zone into which no light penetrates.
Why is the open ocean so low in productivity?
In surface waters away from coastlines, generally there is plenty of sun but not enough nutrients. So most of the ocean surface is not very productive. The water is too deep for storms to stir up nutrients from the bottom and there isn't upwelling.
Why is open ocean so low in productivity?

What is the average temperature of the ocean surface?
62.6 F "The average temperature of the ocean surface water is about 17 °C (62.6 F)." "So even though surface waters can be a comfortable 20 degrees Celsius (good for swimming in!), the majority of our ocean water has a temperature between 0-3 degrees Celsius (32-37.5 degrees Fahrenheit)."
