  1. 1. Primary Productivity Honors Biology - Edgar
  2. 9. NPP=GPP-R
  3. 16. phytoplankton Who are the Phytoplankton? Coccolithophore Diatoms Dinoflagellates
  4. 17. Thermocline Depth in meters 0 100 Nutrients Euphotic Zone or Mixed Layer Thermocline 0µM 5µM 10µM 200 0% 50% 100% Light 0° 10° 20° Temperature
  5. 18. Chl, Photos profile 0 25 50 75 100 Depth (meters) 100 10 1 0.1 0.01 % Surface Light Temperature (°C) Photosynthesis (mg C m -3 day -1 ) Chlorophyll (mg m -3 or μ g L -1 )
  6. 19. Gulf of Maine Data: Wilkinson and Jordan Basins Wilk. Basin Jordan Basin
  7. 21. Redfield Nucleic Acids Lipids Proteins Carbohydrates CO 2 Light Nutrients (N, P, etc) The Redfield Ratio 106 Carbon : 16 Nitrogen : 1 Phosphorus Liebig’s Law: Growth of a “plant” is determined by availability of the single most limiting resource.

  12. 34. What do you know?
  13. 36. Figure 2 . Change in chlorophyll (micrograms per liter) in coastal seawater in 4 treatments (Nitrogen and phosphorus together, N alone, P alone, and Control with no addition) over 6 days. (From Vince, S. and I. Valiela. 1973. The effects of ammonium and phosphate enrichment on chlorophyll a, pigment ratio, and species composition of phytoplankton of Vineyard Sound.  Marine Biology  56: 111-134). 
  14. 39. Group Figure Work
  15. 50. 1994 1973 Phosphorous was added – which side of the curtain? 1973 , This entire lake was experimentally fertilized with phosphorous P is also a factor in eutrophication
  16. 51. Why would fish die while algae are flourishing?
