Initial Re sults – De c e mbe r 2018 sur ve y Key points: Clear spatial variation between the north section of San Diego Bay, the central-to-south section, and the bay mouth May be due to difference seagrass density, relative levels of 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
