Mid-Ocean Gyres
|
Low productivity/ low poc/ low export ratio. Strong stratification. Low nutrient inputs. low primary production/ low biomass levels. waters blue
|
|
|
Coastal Upwelling Systems
|
high primary prouction/ high biomass/ high export ratio/ high poc/ high nutrient inputs. waters green
|
|
|
Wavelengths
|
Blue penetrates the deepest/ green next

c14 uptake method
|
c14 is put into a water sample and incubated for up to 24 hours. The water is then filtered, the c14 left on the filter has been made into biomass, which represents photosynthetic rate. 2 problems: phytoplankton die b/c of trace metal contamination. Not sure if represents GPP or NPP.

|
Compensation Depth
|
photosynthesis - respiration; usually at the bottom of the euphotic zone
|
|
|
Sverdrups Critical Depth
|
Integrated Respiration - Integrated Photosynthesis.

|
Spring Bloom
|
Its initiated when the mixed layer becomes shallower than the critical depth, and then photosynthesis is greater than respiration. Occurs in high latitude NA. It occurs after deep winter mixing replenishes nutrients in surface waters and continues until a key nutrient conc. is depleted. During a spring bloom there is max carbon biomass export to the deep ocean.
