Nature Geosci. 1, 95–100 (2008); published online: 20 January 2008; corrected after print: 20 July 2009.

In the version of this Progress Article originally published, Table 1 was incorrect and should have been as shown here.

Table 1 Gross primary production (GPP), respiration (R) and net ecosystem production (NEP) in streams, rivers and estuaries as determined from whole-ecosystem metabolism measurements (see Supplementary Information S2), and global estimates of respiration and net heterotrophy.

Subsequently, the values of global fluvial respiration and global net heterotrophy reported in the text on page 97 were incorrect.

These errors have been corrected in the HTML and PDF versions.
