Key points:

• Clear spatial variation

between the north section

• f San Diego Bay, the

central-to-south section, and the bay mouth

• May be due to

difference seagrass density, relative levels

• f human activity, tidal

flushing effects, etc.

• All points measured along

the bay were sources of carbon to the air

• Potentially due to

winter season inhibiting photosynthetic activity
