Comments P.381 left column 6th paragraph: "The sum of the components discussed above results in a likely range for respiration in the open ocean of 56 Gt C/yr to 76 Gt C/yr, with a central value for total respiration of about 66 Gt C/yr (Table 1). This estimated range of open ocean respiration represents a crude first-order approximation, because in addition to the paucity of data, there are many problems associated with the direct measurement of respiration in open-ocean waters [refs 6, 10, 40], and with the extrapolation of these measurements to larger scales [ref 47]." Please note-table 1 gives range of 55.8 to 76.1 Gt C/yr. Gt C=Giga tonnes C=10^9 tonnes carbon
