One of the Maritime Provinces, Prince Edward Island lies in the Gulf of St. Lawrence and is separated on the S from Nova Scotia and New Brunswick by the Northumberland Strait, which is crossed by the Confederation Bridge (). It is Canada's smallest province but also has Canada's highest population density. The generally low, level island is c mi ( km) long . The following is a list of islands, sorted by population density, and including islands that connect to other island or inland with land mean of transportation (e.g. bridge or tunnel). Contents 1 Most densely populated islands (over 1, people per km²).   Summary: TEHRAN (FNA)- Rapid deoxygenation in the Gulf of the St. Lawrence is caused by shifts in two of the ocean's most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway.

The Gulf of St. Lawrence (GSL), located north of the southwest-northeast trending Appalachian mountain in eastern Canada, is a major sedimentary basin with huge potentials for hydrocarbon accumulation.
