Try this tool and let me know if it gives you an overview of the sea
level changes during the period you mentioned:


Note the links on the left ("Intro" and "Step 1"). The instructions
will walk you through the process. You will click on "Tools",
"Interactive Mapping" and "Launch QUEST". This interactive map should
give you an idea of the sea level changes over a period of time.

Please let me know if this is the sort of thing you are looking for.

According to the graphs found during my research I found the following figures:
10,000 BP  ----> -45m
 9,000 BP  ----> -30m
 8,000 BP  ----> -15m
 7,000 BP  ----> -4m
 6,000 BP  ----> -2.5m

To get this numbers I used the following graphs, I extracted the
figures just by matching x-axis entries with their corresponding
y-axis values (I downloaded them, then expended and printed, after
that used a rule to get the matches):
"Image:Post-Glacial Sea Level.png - Wikipedia, the free encyclopedia":
This figure shows sea level rise since the end of the last glacial
episode based on data from Fleming et al. 1998, Fleming 2000, & Milne
et al. 2005...

"Image:Holocene Sea Level.png - Wikimedia Commons:
This figure shows changes in sea level during the Holocene, the time
following the end of the most recent glacial period, based on data
from Fleming et al. 1998, Fleming 2000, & Milne et al. 2005.

The sea levels I found agreed with the main sources, as you can
confirm on the following articles that I suggest you to read for
further details and explanations:
"Based on geological data, global average sea level may have risen at
an average rate of about 0.5 mm/yr over the last 6,000 years and at an
average rate of 0.1 to 0.2 mm/yr over the last 3,000 years.
Since the Last Glacial Maximum about 20,000 years ago, sea level has
risen by over 120 m (averaging 6 mm/yr) as a result of melting of
major ice sheets. A rapid rise took place between 15,000 and 6,000
years ago at an average rate of 10 mm/yr which accounted for 90 m of
the rise; thus in the period since 20,000 years BP (excluding the
rapid rise from 15-6 kyr BP) the average rate was 3 mm/yr.
A significant event was Meltwater Pulse 1A (mwp-1A), when sea level
rose approximately 20 m over a 500 year period about 14,200 years ago.
This is a rate of about 40 mm/yr. "
From "Sea level rise - Wikipedia, the free encyclopedia":

"Sea level - Wikipedia, the free encyclopedia":

"Ice Ages, Sea Level, Global Warming, and Geology":

At this point you can use the interactive map suggested by my fellow
researcher tutuzdad-ga, just apply the sea level value for the time
you want and see how the Earth's surface was affected:

Search strategy:
"sea level" glacial
"sea level" holocene chart
"sea level" holocene

I hope this helps you. Feel free to request for a clarification if you
find something unclear and/or incomplete.

Hi again!!

I forgot to add the sea level (according to present day) for 5,000 BP:
5,000  ----> -1.5m
