Birmingham Archaeology have been instrumental in the mapping of Doggerland, they have been using data provided by oil comapanies in the course of their explorations, and British geological survey. There was a conforence (how do you spell this word) at B.U about 2 months ago...I feel to be the first to publish and steal a march on other research groups. All good fun. There have been found some incredible salt hills in the Doggerland region, which could mean that there was a long period of deposition , such as the formation of rock salt. I have to look at the conference notes.
