  <dc:description>&lt;p&gt;&lt;span&gt;Existing analyses of salt marsh carbon budgets rarely quantify carbon loss as CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;through the air–water interface in inundated marshes. This study estimates the variability of partial pressure of CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;(&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;) and air–water CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;fluxes over summer and fall of 2014 and 2015 using high-frequency measurements of tidal water&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;in a salt marsh of the U.S. northeast region. Monthly mean CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;effluxes varied in the range of 5.4–25.6 mmol m&lt;/span&gt;&lt;sup&gt;−2&lt;/sup&gt;&lt;span&gt;&amp;nbsp;marsh d&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt;&amp;nbsp;(monthly median: 4.8–24.7 mmol m&lt;/span&gt;&lt;sup&gt;−2&lt;/sup&gt;&lt;span&gt;&amp;nbsp;marsh d&lt;/span&gt;&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt;) during July to November from the tidal creek and tidally-inundated vegetated platform. The source of CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;effluxes was partitioned between the marsh and estuary using a mixing model. The monthly mean marsh-contributed CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;effluxes accounted for a dominant portion (69%) of total CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;effluxes in the inundated marsh, which was 3–23% (mean 13%) of the corresponding lateral flux rate of dissolved inorganic carbon (DIC) from marsh to estuary. Photosynthesis in tidal water substantially reduced the CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;evasion, accounting for 1–86% (mean 31%) of potential CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;evasion and 2–26% (mean 11%) of corresponding lateral transport DIC fluxes, indicating the important role of photosynthesis in controlling the air–water CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;evasion in the inundated salt marsh. This study demonstrates that CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;evasion from inundated salt marshes is a significant loss term for carbon that is fixed within marshes.&lt;/span&gt;&lt;/p&gt;</dc:description>
