I want to plot global sea level changes for the past 140,000 to determine trends in marine taxa radiations in the oceans. I have been unable to find data sets from NOAA.
Try this publication in the USGS Library. I think you will find what you are looking for in Figure 1.
Past, Present, and Future Sea Level Rise and Effects on Coasts Under Changing Global Climate (Chapter C of Sand Resources, Regional Geology, and Coastal Processes of the Chandeleur Islands Coastal System: an Evaluation of the Breton National Wildlife Refuge). Scientific Investigations report 2009-5252.
Not sure if you are looking for an already completed dataset for global changes, or trying to compile it from regional sources....at any rate, here are a few references mostly from the circumpolar world with "sea-level" in the title. Cheers, Richard
