Sea level measurementsPaleo indicatorsOur estimates of sea level before the earliest tide gauge records (17th century) are dependent on what are referred to as "paleo" indicators. These are indicators (usually natural, but sometimes man-made) whose age, and whose height, relative to modern-day sea level can be measured accurately enough to give worthwhile measurements of past sea level. While these measurements are not nearly as accurate as modern instrumental techniques they can still give useful restraints on sea level histories due to the long time period. Some of the natural markers are:
Some of the man-made markers are:
