“An early proposal for uniform usage in the study of mass balance came from Mark Meier (1962). The terms and the organizing framework of that paper provoked considerable interest and discussion, and evolved into a consensus which was published as Technical Papers in Hydrology , No. 3, by UNESCO/IASH in 1970, although the source most often cited is Anonymous (1969), a digest of the UNESCO/IASH recommendations which appeared in the Journal of Glaciology, 8(52), 1969.”
