The map above shows the 5 metre tide level over the South East of England, I will now try to show you
why I believe this is relevent to the history of the Saxons.
Lets take an area I know - the Pevensey Levels in Sussex.
and look at the Saxon place names which refer to islands these places are all derived from the Saxon word æg
which has been shown to refer to modern place names starting in eg, ending in ay or et or ey
or ly or ney or sea or sey or ye, or containing eye or island.
So lets take a look at modern Pevensey and see if we can make it into an island.
The following images are derived from Google Maps with the sea level overlays provided by Alex Tingle
The map above shows the current sea level, Pevensey is not an island
This map shows what the land would look like if the Sea Level rose by 1 metre, Pevensey is still land based.
This map shows what the land would look like if the Sea Level rose by 2 metres, Pevensey is starting to look more like an island.
This map shows what the land would look like if the Sea Level rose by 3 metres, Pevensey is still not an island.
This map shows what the land would look like if the Sea Level rose by 4 metres, Pevensey is looking more like an island
but still not there yet.
This map shows what the land would look like if the Sea Level rose by 5 metres, Pevensey is now an island.
Is this 5 metre mark valid across the country, so lets take a look at the area around the Wash.
This map shows the 5 metre mark near the Wash, as you can see Thorney, Wattlesey, Ramsey, Southery and Ely are all
islands with the sea level at this height.
So the logical conclusion is that the high tide level was up to 5 metres higher
than today, or the modern sea defenses are blocking this rise.
I think this is a valid argument for a 5 metre sea level so we need to overlay all our maps with this and see what this shows, the
map at the top of the page shows what effect this would have on the South East of England. As you will see on the top map, most
of the river valleys would have been accessible from the sea, the Romney and Pevensey Marsh areas together with the area
around Worthing were salt marshes.
The 'Time Team' carried out a dig at 'Bawsey st Peter' in Norfolk and found a causeway to the island there, this also ties
in with the increase in high tide level by about 5 metres, the Saxon name Bawsey either means 'Pasture Island' or 'Boars Island'
so more evidence that the 5 metre mark is valid.
