Why do we care about Oceanography? Questions for you:

Biodiversity Medical potential/drug discovery New models of life Climate Fisheries Things to think about: Recreation Fossil fuel resource Ocean energy Navigation/transportation Carbon cycle Marine biology Hazards

4 Ocean & Energy

5

Ocean & Hazards Sea surface temperature in the tropical oceans fuel hurricanes Hurricanes becoming more intense as ocean warms?

7 Ocean & Drug Discovery

8 The ocean plays a dominant role in heat transport and mixing Ocean & Climate

9 NORTH AMERICA Gulf of Alaska Thomson, R. E., and J. F. R. Gower, 1998: A basin-scale oceanic instability event in the Gulf of Alaska. J Geophys Res-Oceans, 103, Vortices are the strongest mixing agent in the ocean. They influence the ocean circulation and biology. Ocean & Climate

10 Global Surface Temperatures and Sea Level are rising Ocean & Climate Change

11 Global Surface Temperatures and Sea Level are rising Ocean & Climate Change

12 Ocean climate affects fish distributions and abundance Sardines/Anchovies synchronized alternations between sardines/anchovies over the entire Pacific Ocean? Ocean & Climate & Marine Ecosystems

13 Marine Ecosystem regulate the cycling of chemical species relevant to climate (e.g. Carbon Dioxide) Chlorophyll Spring 2005 (MODIS Satellite) Ocean & Carbon Cycle

14 Ocean & Carbon Cycle

15 Ocean & Marine Biodiversity

16 Ocean & New Model for Life

How do we define the science of Oceanography?

Manu Ocean and climate dynamics Physical-biological interactions in the ocean Ocean Forecasting We studied oceanography in San Diego at the Scripps Institution of Oceanography Kim Climate and paleoclimate El Nino-Southern Oscillation
