The Ocean is the largest of all biomes, covering about 70% of earth's surface. It is home to many organisms that thrive in specific parts and depths of the ocean. It is so vast that a ship as big as the Titanic can sink, and take years to find.



Oceans are split up into four different regions. The intertidal zone, pelagic zone, benthic zone , and abyssal zone.
In general, the ocean has a broad temperature range from warm (38°C) shallow coastal waters of the equator to the nearly freezing arctic waters.Salt water from the ocean is what makes rainwater. Algae controls the levels of oxygen and carbon dioxide in the atmosphere.

intertidal zone: **where the ocean meets the land: communities are constantly changing, and waves keep mud and sand constantly moving **


 * -Organisms in this region are made up mostly of algae and mollusks, snails, crabs, sea stars, invertebrates, fishes, and seaweed **

pelagic zone: ** includes those waters further from the land, basically the open ocean **
 * -The temperature is generally cold though it is hard to give a range since there is a constant mixing of warm and cold ocean currents **


 * -includes surface seaweeds, many species of fish and some mammals, such as whales and dolphins. Many feed on the abundant plankton **

benthic zone: **is the area below the pelagic zone, but does not include the very deepest parts of the ocean **
 * -Temperature decreases as depth increases toward the abyssal zone, since light cannot penetrate through the deeper water **
 * -consists of sand, slit, and/or dead organisms. seaweed since it is very nutrient-rich, include all sorts of bacteria, fungi, sponges, sea anemones, worms, sea stars, and fishes. **

abyssal zone: **// the deep ocean, m //id-ocean ridges, large amounts of hydrogen sulfide **
 * -very cold (around 3° C), highly pressured, high in oxygen content, but low in nutritional content **
 * -many species of invertebrates and fishes **

This video has information and a look at consequences of overfishing and what it will do to the ocean's population over the years to come. People are going after certain fish, collecting others in the process and killing them without reason, and if they catch too many they go to waste as well. There aren't going to be nearly as many species around in a few generations if this continues the way it's going now. media type="youtube" key="umAeFKF2uxA" height="315" width="420" align="center"

This video talks about the Arctic ocean and how creatures survive in this cold environment. Just like terrestrial biomes, the ocean temperature varies for distance from the equator. We have yet to discover much about this portion of the ocean.

http://www.oceanicsociety.org/conservation This website discusses plans of conserving the world's oceans and steps they are taking to make it and it's organisms last longer than they are expected to. There are different links connecting to certain species like sea turtles, whales, or to sanctuaries that help out.

http://ocean.nationalgeographic.com/ocean/critical-issues-marine-invasive-species/ For years we've seen the same species in certain pats of the world. Today, we are seeing creatures small and large swimming a far way to find new live in a new country, even ours. They repopulate in this new area and become common. This talks about what species we're beginning to see and how exactly they're getting here.
