Presentation Transcript

  1. Productivity

  2. Measuring Productivity: Step 1- Light & dark bottles Depth m (ft) (Text Fig. 14.3 pg. 397)

  3. Measuring Productivity: Step 2- Oxygen->Carbon (Text Fig. 14.1 pg. 395)

  4. Wind-induced upwelling Fig. 14.4C Fig. 14.4A Fig. 14.4B (Text Fig. 14.4 pg. 399)

  5. Global productivity on land and in the sea (2001-2002) Primary productivity (kgC/m2/year) (earthobservatory.nasa.gov/Newsroom/NPP/npp.html)

  6. Global ocean productivity (1997-2003) NOTE: 1) seasonal wind-driven upwelling to east of southern S. America & to west of northern S. America; 2) two seasonal productivity peaks at mid-north latitudes; 3) consistently low productivity in open ocean regions N & S of equator; 4) seasonal (weak) productivity pulses along equator Primary productivity (kgC/m2/year) (earthobservatory.nasa.gov/Newsroom/SeaWiFSNPP/seawifs_npp_linear_lrg.mov)
