An epeiric sea--also known as an epicontinental sea--is a large but shallow body of salt water that lies over a part of a continent. Usually associated with the marine transgressions of the early Cenozoic and other eras, they can be warm or cold; indeed, several were present at the end of the last Ice Age.

An epeiric sea--also known as an epicontinental sea--is a large but shallow body of salt water that lies over a part of a continent.
Usually associated with the marine transgressions of the early Cenozoic and other eras, they can be warm or cold; indeed, several were present at the end of the last Ice Age.
Modern examples are the Persian Gulf, the North Sea, and Hudson Bay.
Although rare today because of the overall lowstand of sea level, epeiricseas were widespread in the past during highstands of sea level, such as the early and middle Paleozoic, and for many times provide the only record we have of the marine realm.
Given the importance of epeiricseas for the record of global marine diversity and given the lack of modern analogues for epeiricseas, a systematic approach to the study of these ancient systems is warranted.
The main goals of the study are 1) to apply a quantitative circulation model to Middle and Late Ordovician epeiricseas of Laurentia to test various hypotheses of circulation and 2) to identify mechanisms of rapid oceanographic change that caused faunal extinction and immigration events.
