Abstract
A VERY large tabular iceberg was observed as it drifted north-east of the Grand Banks of Newfoundland during May and June 1976. When the iceberg was first sighted on 12 May 1976 it showed only minor signs of deterioration. From 12 May until last sighted on 6 June the iceberg underwent a rapid reduction of the above water surface area with the erosion largely confined to the turbulent layer associated with gravity waves. The erosion progressed along lines parallel to the structure of the iceberg as indicated by the pronounced ridge pair seen in the photographs (Fig. 1), a trellis drainage pattern, and an alternation of light and dark bands over the entire surface of the iceberg.
