The organic carbon flux studies are summarized in Herrmann et al. (2015) and the inorganic carbon flux studies are summarized in Najjar et al. (2018). These studies were scaled to all of North America using estimates of tidal wetland area."^^xsd:string; gcis:assessmentOfConfidenceBasedOnEvidence "The low confidence is due to the limited number of measurements and time periods. There is appreciation, however, that at a continental scale, there is a strong likelihood that tidal wetlands export carbon to estuaries, although the magnitude of the flux is highly uncertain."^^xsd:string; gcis:newInformationAndRemainingUncertainties "The major uncertainty in this Key Finding is the limited spatial and temporal extents of the 16 individual flux measurements. Tidal wetlands are highly heterogeneous and vary in their processing of carbon on a wide variety of timescales. Hence, tidal wetlands are likely to have been undersampled in terms of lateral exchanges. However, tidal wetlands consistently export carbon and the range of estimates is less than an order of magnitude."^^xsd:string; a gcis:Finding . ## This finding cites the following entities: <https://data.globalchange.gov/report/second-state-carbon-cycle-report-soccr2-sustained-assessment-report/chapter/tidal-wetlands-and-estuaries/finding/key-message-15-3> prov:wasDerivedFrom <https://data.globalchange.gov/report/second-state-carbon-cycle-report-soccr2-sustained-assessment-report/chapter/preface/figure/figurep-4>.
