1903 A. Geikie Text-bk. Geol. (ed. 4) I. 386 De Geer has traced lines of equal deformation round this centre, and has found that these lines (isobases) group themselves in concentric circles.

1924 J. G. A. Skerl tr. A. Wegener Orig. Continents & Oceans 22 The isobase maps of de Geer..show a depression of the central portion of Scandinavia of at least 250 m.

1957 J. K. Charlesworth Quaternary Era II. xlv. 1289 (caption) Map of the sea's greatest area in Baltoscandia (black), with areas of most important glacier-lakes (shaded) and isobases of uplift in metres.

1969 G. M. Bennison & A. E. Wright Geol. Hist. Brit. Isles xvi. 366 It is still not possible to construct accurate isobases (lines joining points of equal uplift) for Britain, as has been done in the case of Scandinavia.
