In the second and third sentences of the first paragraph starting on page 2651, the sign of the entropy difference is incorrectly stated. The sentences should read “If the entropy difference is positive , then it is impossible for the system to attain its reference state. If the difference is negative , then the availability is less than the difference in total potential energy .”
The analysis of the World Ocean Atlas 2005 (WOA05) mean ocean assumed that the reference ocean has a uniform salinity. This assumption does not account for barodiffusion. A correct analysis for the global ocean is contained in Bannon and Najjar (2014).
These corrections do not alter the main result of the paper that proved the relation (1.1) between the availability function and the departures in energy and entropy between a geophysical system and its isothermal reference state.
