Assignment 7: Emergy evaluation of Estuarine losses
Compartment (Organism) |
Output g C/yr |
Phytoplankton |
1.54E+13 |
Zooplankton |
4.21E+11 |
Squid/Herring/Shrimp |
1.54E+11 |
Pink & Chum Salmon |
3.33E+10 |
Salmon/Cod/Halibut/Sole |
1.21E+10 |
Seal/Porpoise |
3.03E+09 |
Apex Predator |
9.99E+08 |
Part B: Compute UEVs for each of the compartments using the following assumptions
Emergy driving the system = Emergy for Prince William Sound (Assignment 6)
Energy/g carbon = 9 Cal/g
J/Cal = 4187 J/Cal
Part C: Compute the losses based on the following estimates of quantity and time;
Compartment (Organism) |
Loss (% of compartment) |
Time (years) |
Phytoplankton |
30% |
0.03 |
Zooplankton |
50% |
0.045 |
Squid/Herring/Shrimp |
24% |
0.65 |
Pink & Chum Salmon |
24% |
1.5 |
Salmon/Cod/Halibut/Sole |
20% |
3 |
Seal/Porpoise |
5% |
1 |
Apex Predator |
1% |
1 |
Part D. Compute the losses in Dollars assuming a global average sej/$ (see NEAD)
