3. Do Now- Review for Ocean Test (12/10)- 10 a day until test Coral Pynocline- layer created by increase in density Thermocline- layer created based of dramatic drop in temp due to less sunlight The curving of currents on earth due to earth’s fast rotation, curves ocean currents Large, circular rotating currents in every ocean on earth The under current that carries nutrient upward toward the shore SONAR- disrupts echolocation/hunting and communicating Human Error! It is floating device that stops floating contaminants from spreading Mercury enters the food chain Chemicals are biomagnified to top of food chain

4. Atoll, Barrier Reef, Fringing Reef 44% Runoff from land, 33% air pollution Eutrophication causes life to die then bacteria consume all O2 Point- sewage, construction site, farm, oil spillNon- trash, soap from cars Biomagnification- accumulates higher up food chainbioaccumulation- accumulates at it gets older Gravitational pull of Sun and Moon Floating plastic trash that runs-off from land Pacific

5. The under-current that brings nutrients to the coast to feed the food chain Global Warming Mercury- biomaginification Booms Skimmer Sorbents Burning Chemical Dispersant

6. Sediment and dissolved minerals from land A large rotating ocean current, plastic trash The gravity of the moon; Spring= higher Neap=lower Tourism, coral bleaching (global warming), dynamite fishing 1. 44% Runoff from land 2. 33% air particulates Kuwait(Gulf War) and BP Cigarette butts Plastic Sonar- disrupts dolphin echolocation Absorption of CO2, increased acidity of oceans Fully or significantly depleted from over fishing
