 ```please let me know changes in sea levels during the period 10000 to 5000 bc at regular (say 1000 year) intervals``` Request for Question Clarification by tutuzdad-ga on 27 Jul 2006 06:12 PDT ```Try this tool and let me know if it gives you an overview of the sea level changes during the period you mentioned: DISCOVER OUR EARTH http://www.discoverourearth.org/student/sea_level/index.html 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. Regards; tutuzdad-ga```
 ```Hi!! 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... http://en.wikipedia.org/wiki/Image:Post-Glacial_Sea_Level.png "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. http://commons.wikimedia.org/wiki/Image:Holocene_Sea_Level.png 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": http://en.wikipedia.org/wiki/Sea_level_rise "Sea level - Wikipedia, the free encyclopedia": http://en.wikipedia.org/wiki/Sea_level "Ice Ages, Sea Level, Global Warming, and Geology": http://hometown.aol.com/gregbenson/iceage.htm 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: "DISCOVER OUR EARTH": http://www.discoverourearth.org/student/sea_level/index.html 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. Regards, livioflores-ga``` Clarification of Answer by livioflores-ga on 28 Jul 2006 05:49 PDT ```Hi again!! I forgot to add the sea level (according to present day) for 5,000 BP: 5,000 ----> -1.5m Regards, livioflores-ga```
