In the big new paper by the BRITICE-CHRONO team, I'm increasingly intrigued by the persistence of the idea that there was a Devensian ice-free enclave incorporating mid and south Pembrokeshire. The maps created by the research team do not show a complete enclave, since they show an ice-free corridor running to the SE, but it is clear that it has caused great difficulty to those who were doing the ice sheet modelling! You can pick this up both from the text and the illustrations.
The authors claim that this enclave is something shown by the empirical evidence -- but they provide no evidence whatsoever in support of it, and I think they should have dumped it when it became clear that it was glaciologically vanishingly unlikely to have existed at the time of peak glaciation -- 26,000 yers ago.
As indicated in other posts on this blog, I now think that mid and south Pembs were affected by Devensian ice, even though it might have been thin, sluggish and short-lived. I'll try to publish more on this in the coming days.
Here is another of the reconstructions from the paper:
It shows just how difficult it was to accommodate this concept into the modelling.........
