Question
Suppose a 100 km? section of the ocean in a central gyre is
selected for intense study. The depth of water is 5000 m, and
the surface mixed layer is 100 m deep. The daily net
photosynthetic production is measured to be 5 x 10% mol per
day.
What is the primary productivity (in g m? yr)?
Hints:
1 km? = 10 m?
1 yr = 365 days
1 mol C = 12.011 g
