DOGGERLAND
After the last ice age 20,000 years ago, the North Sea was frozen in a glacier and Britain was joined to mainland Europe by a fertile lowland inhabited by thousands. As the climate warmed the glacier melted and Doggerland became submerged. We are on the same global warming trajectory. A research project, Europe’s Lost Frontiers, has been exploring this lost landscape looking for evidence of human settlement and migration linked to climate change over millennia.
The Lost Frontiers team gave me fragments of Doggerland core ELF02 from below the North Sea bed. This sample “probably would have been formed when this part of Doggerland was a dry land environment, before inundation”

ACOUSTIC MIRRORS
Below are acoustic mirrors that work to amplify the sound produced within one end of the passage, similar to the acoustic tunnel created by the mole cricket, its structure is designed to strengthen the noise when leaving the other side.
Mole Crickets are well known for creating elaborate singing burrows. The burrows have a bulb dug out in the middle below ground, this helps with the resonation of the sound, the song get pushed out of the burrow exit which often has two exit holes amplifying the sound even more, the mole crickets song can be heard from up to 1 mile away from its nest in a quieter area. We have on the plinth 3D prints of two mole cricket burrows, this is the negative of the burrow underground. Both scans to print were available from the Natural History Museum.
