Transcript of "Deep Ocean"

  1. 1. By: Alexa Murphy Deep Ocean
  2. 2. Definitions <ul><li>Homeostasis: The ability of the body’s systems to maintain a constant or balanced internal environment. </li></ul><ul><li>Deep Ocean: Deep Ocean occurs when there is a rapid change in density separating the surface layer of ocean from the deep layer of ocean. </li></ul>
  3. 3. Deep Ocean Conditions <ul><li>Temperatures range from 2-4 degrees Celsius. </li></ul><ul><li>Pressure Ranges from 200-600 atm </li></ul><ul><li>“ Oxygen Poor” </li></ul><ul><li>No light it present </li></ul>
  4. 4. Deep Ocean Creatures <ul><li>Adaptations : large eyes, bioluminescence, strong sense of smell, absence of swim bladder, expandable stomachs, absence of jaws, and color (for camouflage and protection from predators). </li></ul><ul><li>Types of Creatures Include : Viper Fish, Angler Fish, Amphipods, Colossal Squid, etc </li></ul>
  5. 5. Humans in the Deep <ul><li>The record holding free diver dove 417ft deep. </li></ul><ul><li>The deepest scuba diver has gone is 475ft. </li></ul><ul><li>The British ship Challenger first found and surveyed deep waters in 1951 </li></ul>
  6. 6. Affects on Humans <ul><li>Three most affected systems: </li></ul><ul><li>- Respiratory </li></ul><ul><li>- Circulatory </li></ul><ul><li>- Nervous </li></ul>
  7. 7. Respiratory System <ul><li>Because there is almost no oxygen in the deep ocean, humans do not have the ability to breath on their own. </li></ul><ul><li>Human Lungs are adapted to only about 1 atm, therefore they could not handle the pressure. </li></ul>
  8. 8. Circulatory <ul><li>If a person ascends too quickly Nitrogen (in the compressed air) can form bubbles in their blood. </li></ul><ul><li>This can cause blocked blood flow. </li></ul>
  9. 9. Nervous <ul><li>Both Nitrogen and Oxygen can be toxic at high pressures. </li></ul><ul><li>Inhaling too much can cause a person to seizure while under water. </li></ul>
  10. 10. Equipment Used <ul><li>ROVs (remote operated vehicles) are used to explore the deep. </li></ul><ul><li>Submarines are also used for expeditions with humans, because they can handle the pressure. </li></ul><ul><li>Humans: When diving need a wet suit to help maintain body temp. Also need an air tank to receive proper oxygen </li></ul>
