Number Type: real Missing Value Code: -9999.0000 (Value will never be recorded) Methods Sampling Description Gas samples were taken from 6 sq. cm sections on individual leaves. These leaves were always sampled from the surface to about 2.5 m height and leaves were selected that received direct sunlight. Measure transpiration rates and photosynthesis rates of individual Red mangrove leaves under varying sample cell carbon dioxide concentrations. Vmax, the Rubisco limited carboxylation rate, is determined from this procedure. Method Step Description The flux of carbon dioxide and water vapor was monitored from a number of leaves. Fluxes were only measured once a steady state value was reached. This typically took about 30 seconds to 60 seconds to occur. Light level was held at 1000 micromol m-2 s-1, leaf temperature at 30 C and reference cell CO2 mixing ratio (in parts per million) was sequentially decreased as follows - 380, 330, 280, 230, 180, 130, 80, 30. Instrumentation LiCor 6400 Gas Exchange system equipped with a red/blue light source in the sensor head. Quality Control Dataset is inspected by PI for QA/QC; standard validation checks for negative numbers, graphs to detect potential outliers . Maintenance knb-lter-fce.1149.3: Updated metadata to EML 2.2.0, added creator ORCID and organization ROR ids, changed data file extension to .csv (no changes to data) Dataset Contact Name: Jordan Barr Position: Scientist, data manager Organization: Everglades National Park Address: South Florida Natural Resource Center Everglades National Park 3rd Floor, 950 N Krome Ave Homestead, FL 33030 USA Phone: 305-224-4254 Email: jordan_barr@nps.gov URL: http://www.nps.gov/ever/naturescience/sfnrcstaff.htm Position: Information Manager Organization: Florida Coastal Everglades LTER Address: Florida International University 11200 SW 8th Street, OE 148 Miami, FL 33199 USA Email: fcelter@fiu.edu URL: https://fcelter.fiu.edu Dataset Submission Date 2002-08-15 Data Submission Notes Using the LiCor 6400 gas exchange system is not entirely straightforward.
