By 2050 sea level rise will push average annual coastal floods higher than land now home to 300 million people according to a study published in nature communications. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around.

Geographic features above sea level are recorded with positive numbers such as 10 and 20 representing for example meters above sea level. Rising waters mean less land to live on.
