Eco-Column Reports due December 13th “Do right ‘till the stars fall!” Week #9 Quarter 2 (12/9/13-12/13/13) (calendar site) Monday, 12/9/13 Activities/Assignments: Stamp Aquatic Ecosystem Notes Finish Oceanography Notes Grade Ch. 1-3; 5-6; 23-26 Study Guide

Review Objectives and Scales

I. Trenches Deep narrow crevices in the ocean floor Near the edge of continents at subduction zones Deepest is Marianas Trench 11000 m deep

J. Mid-Ocean Ridge Large underwater ocean mountain ranges Make one continuous chain around the world Formed when molten liquid comes up and forms new crust Consists of a valley between two parallel mountain ranges Valley is called a rift valley

The Ocean Floor

III. Ocean Water A mixture of water and dissolved gases and solids Water is H2O (2 hydrogen and 1 oxygen). 96% of ocean is pure water (H20) 4% dissolved stuff Most elements have been found in ocean water

A. Ocean Water Composition Sodium chloride most abundant Common table salt Salinity – the number of grams of salt dissolved in 1000 grams of water. Units are parts per thousand (ppt) If you evaporated 1 kilogram of water with a salinity of 35 ppt You would have 35 grams of salts

Ocean Water Salinity of ocean water varies from place to place Between 33 and 37 ppt

Ocean Water Sodium chloride 27.2 ppt Magnesium chloride 3.8 ppt Magnesium sulfate 1.7 ppt Calcium sulfate 1.3 ppt Potassium sulfate 0.9 ppt Calcium carbonate 0.1 ppt Magnesium bromide 0.1 ppt Ocean Water

B. Sources of Salt Dissolved materials come from several sources Volcanoes add gases, especially chlorine Erosion adds dissolved salts Rain erodes minerals Rivers carry them into ocean

C. Salinity varies It is lower where rivers flow into oceans Large rivers like the Mississippi and the Amazon have the biggest effect Lots of freshwater dilutes the salt water. Area with lots of evaporation & little precipitation makes the water have higher salinity In polar regions: more precipitation than evaporation – lower salinity In equator regions: evaporation = precipitaiton

D. Ocean Temperature Sun supplies the heat Water temperature is highest at surface Waves mixes surface water transfer heat downward Region where heat is mixed is called the surface zone In surface zone temperature is fairly constant warm Surface zone varies in depth

Ocean Temperature Surface zone varies by location Caribbean thick Off the coast of Maine thin In Arctic and Antarctic water is so cold there is no surface zone Varies with seasons Thermocline- region below the surface zone Water temperature drops with depth Cold deep water doesn’t mix with warm surface water

Ocean Temperature Deep zone- Extremely cold water from bottom of thermocline down Three zones vary in thickness
