How can scientists measure sea level rise?



  1. 0 Votes

    Scientists use a device called a tide gauge. These instruments look like ordinary foot-long in diameter pipes that have a hole at the bottom that goes beneath the water line. Despite the always changing water levels of the sea, the water levels within the pipe remain much more consistent. In order to accurately make measurements from a tide gauge, a scientist needs to view the changes over a very long period of time, sometimes several years.
