Why sea levels rise along the East Coast of the US at different rates



Water, water everywhere

Rising sea levels are worrisome. Sea levels rise differently? This is very worrying.

As glacial meltwater continues to cause rising sea levels, monitoring of flood-prone areas is becoming increasingly important. In some areas, sea levels seem to rise faster than others. Therefore, it is difficult to predict which coastal cities are the most vulnerable. New research published in the journal Nature supports a literal epic explanation.

Funky Flow

It would be logical to believe that sea levels in similar geographic areas would increase more or less evenly along the east coast of the US. The problem is that as the sea level rises, the coasts in these areas can sink at the same time. In the new study, which examined sea-level trends along the East Coast of the United States between 1

900 and 2017, the responsibility for an unexpected sea-level rise is put on a phenomenon called the "post glacial rebound".

The post-glacial rebound is a process that has begun During the last ice age, massive ice covered the inland areas, squeezing the land of the earth together and sinking it down. As a result, the remote areas along the coast have been pushed up over time like a massive seesaw.

By comparing tidal readings, GPS data and coastal fossils, the research team succeeded in producing the study A more accurate model for historical sea-level rise.

Chris Piecuch, lead author of the study, concluded that "the rebound after the Ice Age is definitely the most important process leading to spatial differences in sea level rise on the East Coast of the US across the East Coast last century. And as this process evolves over millennia, we are confident to project its influence into the future for centuries.

One Drop at a Time

The forces involved in the post-glacial rebound take place on an epic timescale that is impossible A person as a witness, so do not expect the ground to fall out below you. However, as the sea level continues to rise and the country continues to decompress, some coastal areas become increasingly vulnerable to coastal flooding. Fortunately, Piecuch and his team may have provided a key to identifying the most vulnerable areas.
