Short summary
We report on direct measurements of net ecosystem productivity (NEP) and net ecosystem calcification (NEC) in a Florida Bay seagrass ecosystem. We found notable differences between our carbon-based NEP and similar determinations made using oxygen. Over the study period, both NEP and NEC were negative, revealing that these sites are net heterotrophic and have dissolved CaCO3. Our findings point to sediments maintaining negative NEP and NEC despite high seagrass above-ground primary production.
