What Lies East of the Labrador Sea?

Geographic Answer

The Labrador Sea's eastern boundary is defined by Greenland's western coast—specifically, the westernmost points of Greenland's landmass.

Regional Context

• West: Labrador Peninsula (Canada) — Labrador, Newfoundland, Quebec
• East: Greenland — Nuuk, Sisimiut, Maniitsoq regions
• North: Davis Strait → Baffin Bay → Arctic Ocean
• South: Newfoundland → North Atlantic Ocean

Oceanographic Significance

The Labrador Sea is a marginal sea of the North Atlantic and a critical site for deep water formation. Cold, saline water sinks here, driving the Atlantic Meridional Overturning Circulation (AMOC)—the "global conveyor belt" regulating climate.

Greenland's Western Coast

• Deep fjords carved by glaciers
• Iceberg alley—calving from Greenland Ice Sheet
• Inuit communities with millennia of maritime culture
• Rich fisheries (shrimp, cod, halibut)
• Emerging mineral exploration

Strategic Importance

Thule Air Base (Pituffik Space Base) on northwest Greenland monitors Arctic approaches. The Labrador Sea-Greenland margin is a climate change sentinel region—freshwater influx from melting ice threatens AMOC stability.
