Thalassia testudinum productivity: A field comparison of measurement methods

Thalassia testudinum productivity: A field comparison of measurement methods 227 37 37 1 1 H. F. Bittaker R. L. Iverson Department of Oceanography Florida State University Tallahassee Florida USA Abstract A 6-day in situ comparison between the Wetzel inorganic 14 C uptake and Zieman leaf-biomass techniques for measuring net primary production rates in the seagrass Thalassia testudinum was performed in the northeastern Gulf of Mexico. Measurement differences between the two methods were insignificant when the 14 C uptake technique was corrected for sediment 14 C “uptake” (13%), incubation-chamber light-energy absorption (14%) and differences in total light-energy which resulted from the experimental design (7.7%). These results reinforce previous observations that the 14 C technique estimates net particulate-carbon production. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Marine Biology Springer Journals
