Precipitation - drier western pacific, wetter eastern pacific LA NINA Sea surface temperature- colder than average in central and eastern pacific Thermocline- increased slope up to east, increased upwelling Eastern pacific productivity- increased Trade winds- stronger Precipitation - wetter in western pacific, drier eastern pacific 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? warmer water temp, more precipitation, more storms and waves, less productivity, warmer marine specie offshore. They are generally what we expect to see based off of other el ninos Did the 2015 El Nino end California’s drought? Why or why not? It did not... What is contributing to most of the modern climate warming? Greenhouse gases What is a climate feedback loop? something that accelerates or decelerates a warming trend Explain the following feedback loops: ice albedo - positive feedback climate process where a change in the area of snow covered land ,ice caps,
etc. a;ters the albedo( how much of the suns energy a surface reflects), water vapor- increased global warming , positive feedback What is the effect on ocean chemistry and ocean life of increased CO2 absorption into the ocean? What is contributing to sea level rise? Thermal expansion and ice melting. What is the difference between global sea level rise and local sea level rise? What makes an area more susceptible to sea level rise? -global sea level occurs due to warming of the ocean and local sea level is affected by global sea fluctuations, changes in land elevation, winds, and ocean circulation. -ocean acidification , lowering capability to absorb more CO2 Ecosystems What are ecosystem services? What is meant by “natural capital?” Benefits provided to humans by ecosystems. (ie: forest reducing CO2in atmosphere) Economists trying to put a price tag on natural service, “natural capital”. Estimate that we have lost 2-3 trillion dollars worth of ecosystem services. What are some examples of ecosystem services provided by wetlands? -Fish and shellfish habitat -Bird habitat (permanent & migratory) -Water quality control - filtration -Sediment and nutrient retention, flood control -Storm protection and erosion control -Groundwater recharge, Recreation -Education, Biodiversity, Recreation -Disturbance and natural hazard regulation -Aesthetics, Water supply, Food production What has happened to California’s wetlands? California has lost 90% of wetlands. Due primarily to agricultural and urban development. What ecosystem services are provided by the Tijuana River Valley & Estuary? -Historical and archeological resources -Recreation - Hiking, biking, equestrian trails, picnic areas, beaches & surfing offshore community gardens -Agricultural areas - Sustainable and organic farms -Environmental education programs, Scientific research and restoration -Diverse ecosystems & threatened/endangered species (fairy shrimp, Clapper rail) -Nursery for Diamond turbot and halibut, Offshore marine protected area How has the Tijuana River Valley & Estuary been impacted by rapid urbanization in Tijuana?
