How did TSUNAMIS impact DOGGERLAND?

During the Last Glacial Maximum Britain and the Netherlands were connected by a land bridge. Archaeologists now refer to this area as Doggerland, a vast piece of land inhabited by Mesolithic people. But how was it eventually submerged and how did the Storegga tsunamis contribute to this process?

Always enjoy more about Doggerland. Thanks Laura!

Doggerland was a endless source of fascination for me as a kid.

Laura! You tease! One minute is not enough for this topic.

Dogger land is so fascinating on so many levels. Geologically, oceanographically, biologically and of course archaeologically.

Back in the 1980’s Statoil, now Equinor ASA, the Norwegian national oil interest conducted extensive Geo-seismic profiles in the North Sea, including on Dogger Bank to define the oil bearing strata. This data led to an understanding of the subsidence of the North Sea basin. As glacial ice melted sea level rose. Mass was also removed from the surrounding rocky formations allowing them to rise. The softer Dogger land basin sank down in what could be seen simplistically as a teeter-totter effect. This put Dogger land underwater. The resultant geologic stresses resulted in numerous sloughing events resulting in tsunamis as you report.

Fishing boats and scallop dredges pull up all manner of bones and artefacts. Sadly only a fraction are sold to collectors while the bulk is disposed of in land fills. What a waste. But this does suggest the staggering biomass supported there when it was above sea level.

Emerging technology such as acoustic LiDAR and detached ROV may allow more detailed exploration archaeologically in an area too deep for conventional diving.

Your amigo, Kayleigh, made one of the best presentations about 2 years ago. And yet there was much she passed over. There is still some meat on that bone. Time for you or she (or both of you) to give it a gnaw?

Quite comprehensive and yet, very brief.

This is incredibly interesting! And I know it’s generally regarded as a hoax, but is there any evidence for any tsunami around 2200BC as the Oera Linda Book claims? This reminded me of reading it all those years ago and the part that talked about the waves rose so high over the land that they thought all was lost, but it seems such an event could have happened in that area.

hi, Laura! somehow i missed this one😅😂🤣 very interesting, tsunami-caused swamping, at least, a major part of the process....such a fascinating area. i sure get a lot of interesting pieces of the puzzle from your research😊 and, you do all the work! thank you!

Fox mentioned Klee's vid and how there's more to discover and maybe you, she or both should create more on say "here, here!!!" a video on Doggerland from my two favorite historians! i would think i had died and gone to heaven😍 maybe? someday? of course, i'd watch any, together or not....one a my favorite, mysterious places. ciao, for now

The final date for the submergence of Doggerland by rising seas matches the date assigned for the flooding that filled the Black Sea, about 6500 BC. In the Mediterranean sea level rose about 400 feet and that tallies with the current depth of the Turkish straits where they meet the Black Sea. So there was something significant that happened to world sea level rise about 6500 BC.

Just curious, why is that important or significant as us amateurs would like to know. :)

Its interesting how Doggerland said out loud sounds like a non scandinavian trying to pronounce the name- Its literally named Diversland, Dogger likely coming from the Dan/Nor/Swe words for diving, because we have æ ø letters- which are common speaking sounds in scandi that are Hard for Many not familier to say out loud,
I wonder though when the name Doggerland became the name? Because if people had already named it Diversland which would Sound similar in scandi languages- kinda makes me Think that at some point someone was aware that this massive bit og land - was- and then wasn’t, Diversland implies that someone was aware that the land was below sea suddenly- and it was known about enough for fereigners to pronounce all kind of Odd ways due to the unique scandi sounds
