(2020): Impacts of wetland dieback on carbon dynamics: A comparison between intact and degraded mangroves [dataset publication series]. PANGAEA, https://doi.org/10.1594/PANGAEA.910433 To measure CO₂ we used a CO₂ sampling data logger from the company CO2Meter, Inc. (https://www.co2meter.com/). The model was a CM-0002 gas detector handheld which has a measurement range of 0 – 10.000 ppm (0-1%) CO₂ with an accuracy of ± 30ppm ± 3%. The handheld is using the non-dispersive infrared (NDIR) method to determine CO₂ concentrations. Before each measurement the CO₂ data logger were calibrated to outdoor air which was assumed to have a CO₂ concentration of 400 ppm. At each sampling plot at low tide three CO2-Meters were positioned adjacent to each other but not covering pneumatophores or crab holes to avoid extra respiration not from the sediment-air interface. A chamber with 305 ml of volume was installed on the sediment and shaded to maintain temperature inside the chamber steady. Furthermore the chamber was darkened to prevent any respiration of ecosystems (Reco). Inside the chamber a HOBO temperature logger was positioned, with a logging interval of one minute. After setting up the instruments for measurements we waited between approximately 10 minutes until we started the logging. This was because the logging needed to start after any sediment disturbance has occurred. Each measurement took between 17 and 25 minutes. Data was considered to be obtained under steady state conditions if the temperature did not change more than 1.5 °C (Chojnicki et al., 2009). 16360 https://doi.org/10.1594/PANGAEA.910406 2020-01-07T10:45:14+0000 2020 14934 20683 15245 20684 15331 20685 20686 14464 20687 20690 20691 20692 20693 20694 20705 20706 20707 20708 20709 20710 20695 20723 20696 20697 20698 20699 20700 20701 20702 20703 20711 20712 20713 20714 20715 20716 20717 20718 20719 20720 20721 20688
