Previous Pliocene Research

Other researchers have tried to determine how high the sea was during the Pliocene. They’ve used a variety of techniques and come up with a wide range of estimates, from about the same as present to more than 80 feet higher. Below are some of the far-flung fields sites where these scientists have taken samples for their studies.

VIRGINIA

Researchers from Rutgers University drilled into sediment collected in a crater left by a meteorite millions of years ago. Analyses of their samples suggest that the sea was 33–59 feet higher during the Pliocene. LEARN MORE

NEW ZEALAND

A shallow marine basin that later uplifted has given New Zealand researchers evidence of Pliocene sea level 49–65 feet above that of today. LEARN MORE

ENEWETAK ATOLL

Scientists from the United States Geological Survey sampled fossil corals beneath a crater left by hydrogen bomb tests. Studies of the organisms suggest that Pliocene sea level was 67–82 feet above that of today. LEARN MORE
