What is an ocean gyre? What are the differences between a Western boundary current and an Eastern boundary current in terms of speed, size, and temperature? What is the one example of an eastern boundary current? Western boundary current?Explain the temperature and productivity of California’s coastal ocean in terms of gyre circulation and Ekman Transport.What controls water density? Where are the densest surface waters found on the earth? How do densitydifferences drive ocean circulation? What is this type of circulation called?ClimateWhat is the difference between weather and climate?Explain why a record cold winter in New England does not mean that earth’s climate isn’t warming.What is the approximate timing of a glacial cycle? What controls these cycles? (you do not need to know each term, but just that there are changes in earth’s orbital patterns that impact incoming solar radiation) What part of the cycle are we currently in?What types of data or proxies can be used to reconstruct earth’s climate prior to measurement with thermometers? (Focus on the 2 we discussed in class)What can we learn about earth’s past through studying ice cores?What can we learn about earth’s past through studying ocean sediments?
Where do the conditions for El Niño develop?What are the “warm pool” and “cold tongue?” How do they change during El Niño conditions? La Niña conditions?What conditions define an El Niño compared to neutral conditions? (in terms of sea surface temperature, thermocline position, productivity in the eastern Pacific, trade winds, and precipitation patterns) – make sure you refer to the geographic area you are talking about (i.e., the water gets warmeris not enough because some areas also get colder. Tell me where you are talking about)What does southern California typically experience during El Niño in terms of weather and ocean patterns? Why? Are these patterns consistent between different El Nños?Will the 2015 El Nino end California’s drought? Why or why not?What is contributing to most of the modern climate warming? What is an example of a climate feedback loop?What is the effect on ocean chemistry and ocean life of increased CO2 absorption into the ocean?What is contributing to sea level rise? What is the difference between global sea level rise and local sea level rise? What makes an area more susceptible to sea level rise?
