Dissolved Oxygen / Density of Water vs. Ice	Estuaries / Pycnocline	Shadow Zones	Sofar Channel	Thermocline / Halocline
100 High amount of Dissolved oxygen in a lake indicate Better water quality	100 An estuary is best defined as a place where fresh and salt water meet	100 What are shadow zones casued by? S waves being stopped entirely by the liquid core and P waves being bent by the liquid core	100 When was the SOFAR channel discovered? 1940's	100 The layer in which temperature rapidly decreases thermocline
200 If sample water does not contain enough microorganism then what needd to be Seeding the sample	200 A watershed is defined as land that drains water into a particular set of rivers	200 What did the seismic shadow zone prove? the interior of the Earth must contain a layer of liquid material	200 How are SOFAR channel formed? by the interplay between changes in ocean temperature and pressure with increasing depth	200 The drop in temperature as depth increases is termed the thermocline
300 What method used to measure Dissolved Oxygen in this experiment Winkler's method	300 What body of water is NOT affected by river pollution in Virginia Pacific Ocean	300 How deep is a shadow zone? around 2 kilometers below the surface of the Indian and Pacific Oceans	300 What is SOFAR channel? allows sound to carry great distances	300 At the equator, the thermocline relatively deep
400 How does the density of water compare to the density of ice? Molecules in the water	400 The layer in which density increases pycnocline	400 What is shadow zone in Sonar? a region of low sound intensity that shadow waves traveling away from a source in the ocean do not reach	400 Do whales use SOFAR channel? Baleen whales appear tot ake afvantage of this SOFAR channel to broadcast songs for great distances	400 A layer of water below the mixed surface layer where a rapid change in salinity can be measured as depth increases Halocline
500 At what temperature is water the same density as ice? 0 degrees celcius	500 Why is pycnocline important to plankton? induces vertical exchange of nutrients, mainly by IWs, sustaining a substantial proportion of the total oceanic primary production	500 Why is the S-wave shadow zone larger? S-waves do not travel through the outer core	500 What causes the SOFAR layer and shadow zones in the ocean? Specific combinations of temp, pressure, and salinity	500 What does halocline tell us about the ocean? allowing for the fromation of sea ice, and limiting the escape of carbon dioxide to the atmosphere
