This is the reconstructed sea level variation for the nearshore areas around Prince Edward Island (PEI), Canada. The Fisheries and Oceans Canada (DFO) only has one permanent tide observation station running in PEI, which is the Charlottetown Tide Station (ID:1700). This reconstruction is to break through the limitation of the lack of long-term high-temporal-resolution regional sea level record around PEI, which applies to 7 more different locations with historic short-term records of temporary tide stations across PEI.
