Abstract

In this reply, we address the issues raised by the comment of Chalmers et al. (2010) regarding our ICE hypothesis for the evolution of western Scandinavia. We reject their conjectures as based, uncritically and without consideration of physical mechanisms, on the long-standing dogma of late Cenozoic tectonic uplift. Our hypothesis, in contrast, honours well-documented physical laws and the present wealth of actual data constraints (as opposed to dogma-biased inferences). After careful consideration of the points raised by Chalmers et al. (2010) we maintain our simple explanation for the evolution of Scandinavian topography, as it honours well-documented actual data constraints, such as crustal structure (including its spatio-temporal variability), thermal history in the eastern North Sea, global and regional climatic change (including eustacy) and sedimentation in the adjacent basins. The inevitable conclusion is that, although more data constraints are desirable, the current best fit hypothesis, is that the Scandinavian topography is of Caledonide origin, and has been shaped by fluvial and glacial buzzsaw and periglacial processes, and most recently (last few Myr) been re-invigorated by extensive glacial erosion in the fjords and on the shelf.
