caption: "Approaches to measuring atmospheric\r\nCH4 flux are coded by method as SC (static chamber)\r\nand EC (eddy covariance flux tower). CH4 flux is in\r\ngrams (g); salinity is in practical salinity units (PSU).\r\nThe dashed line denotes the demarcation of fresh and\r\noligohaline marshes (0 to 5 PSU) versus mesohaline to\r\nsaline marshes (5 to 35 PSU)."
