If you’re looking for Baffin Bay on a map, you’ve gotta look way up. Past the familiar shapes of the Great Lakes, beyond the Hudson Bay’s massive thumbprint, and right into the teeth of the High Arctic. It’s that huge, teardrop-shaped slab of water wedged between Greenland’s icy cliffs and the jagged eastern edge of Baffin Island.
Most people glance at it and see a blank white space. Honestly? That’s a mistake.
It isn’t just a "bay" in the way we usually think of them—like a quiet little cove where you’d park a sailboat. It’s a 260,000-square-mile engine for the planet’s climate. It’s a deep, dark basin where the Atlantic and Arctic Oceans have been fighting a slow-motion tug-of-war for millennia. When you find Baffin Bay on a map, you aren't just looking at geography; you’re looking at the gateway to the Northwest Passage and the front lines of global environmental change.
Where Exactly Is Baffin Bay on a Map?
Finding it is actually pretty easy once you know the landmarks. Start at the tip of Greenland. Follow the western coast down. Now look at Canada. See that massive island that looks like it’s been shredded by a giant claw? That’s Baffin Island. The water between them—stretching from the Davis Strait in the south up to the Nares Strait in the north—is Baffin Bay.
It’s isolated. Seriously isolated.
There are no bridges. No highways lead here. If you want to see it in person, you’re either on a heavy-duty icebreaker or you’re flying into small Inuit communities like Pond Inlet or Clyde River. On a standard Mercator projection map, Baffin Bay often looks way bigger than it actually is because of polar distortion. In reality, it’s about one and a half times the size of California.
The Strange Depth of the Basin
You’d think a bay this far north would be shallow. Nope. While the edges are fringed with shallow continental shelves, the center—the Baffin Basin—plunges down over 7,000 feet. That’s more than a mile of vertical water. This deep pocket acts as a massive reservoir for cold, salty water.
Oceanographers like Dr. Humfrey Melling have spent decades studying how this water moves. It’s a complex dance. Warm (well, "warm" is relative) water from the West Greenland Current flows north along the Greenland coast. Meanwhile, cold, ice-choked water from the Arctic Ocean pours down through the Lancaster and Jones Sounds, hugging the Canadian side. This creates a literal conveyor belt of icebergs.
Why This Specific Spot Matters for Navigators
When you look at Baffin Bay on a map, you’ll notice a series of "holes" or gaps on the western side. These aren't just random inlets. These are the entrances to the legendary Northwest Passage.

For centuries, explorers like John Franklin and Roald Amundsen obsessed over these coordinates. Lancaster Sound, located at the northwestern "corner" of the bay, is the primary gateway. If you’re a ship captain trying to shave thousands of miles off a trip from Europe to Asia, this is the needle you have to thread.
But there’s a catch.
Baffin Bay is notorious for being an "iceberg factory." Most of the massive bergs that end up in the North Atlantic—including the one that famously sank the Titanic—originate from the glaciers of West Greenland and drift through Baffin Bay. They follow a counter-clockwise graveyard lap. They head north along Greenland, cross over toward Canada, and then ride the Baffin Island Current south toward Newfoundland.
Navigating this area isn't just about reading a map. It’s about reading the ice.
The "North Water" Mystery
There’s a feature you can’t always see on a standard paper map, but it’s the most important part of the region: the North Water Polynya.
A polynya is basically a patch of water that stays ice-free even when everything around it is frozen solid. In the northernmost reaches of Baffin Bay, between Greenland and Ellesmere Island, there’s a massive one. It’s often called the Pikialasorsuaq by the Inuit.
Why does it stay open? A mix of powerful winds and upwelling currents keeps the ice from closing in.
Because there’s open water and sunlight hits the surface earlier in the spring, it triggers a massive bloom of plankton. This creates an Arctic "oasis." If you were to overlay a map of wildlife density on top of Baffin Bay, this spot would be glowing bright red. We’re talking thousands of narwhals, belugas, walruses, and millions of seabirds like Dovekies. For the communities in North Greenland and Nunavut, this isn't just a geographical quirk—it's their lifeblood.

The Geopolitics of a Melting Map
As the ice thins, the way we look at Baffin Bay on a map is shifting from a scientific perspective to a political one.
Canada and Denmark (representing Greenland) actually shared the longest-running, most polite border dispute in history over a tiny rock in the Nares Strait called Hans Island. They finally settled it in 2022, literally drawing a line across the island. But that was just the tip of the iceberg—pun intended.
Underneath the seabed of Baffin Bay, there are massive potential reserves of oil and natural gas.
Geological surveys suggest the West Greenland-East Canada (WGC) province could hold billions of barrels of oil. However, drilling here is a nightmare. The water is deep, the icebergs are the size of skyscrapers, and the ecosystem is incredibly fragile. Most companies have backed off for now, but as the "permanent" ice disappears, the map looks more and more like a game of Risk.
Living on the Edge
If you zoom in on a map of Baffin Bay, you’ll see tiny dots representing human life.
- Pond Inlet (Mittimatalik): A hub for narwhal watching and a gateway to Sirmilik National Park.
- Qikiqtarjuaq: Often called the iceberg capital of the world.
- Nuuk: The capital of Greenland, further south but the administrative heart of the eastern bay.
These communities are facing a reality that map-makers struggle to keep up with. The shorelines are changing. The permafrost that holds the ground together is thawing. Traditional hunting routes over the sea ice—routes used for generations—are becoming unpredictable.
How to Read a Baffin Bay Map Like a Pro
If you’re looking at a digital map or a physical atlas, keep these three things in mind to actually understand what you’re seeing:
- The Bathymetry: Don't just look at the blue. Look at the shading. The darker the blue, the deeper the Baffin Basin. This depth is why the bay doesn't freeze all the way to the bottom and why it can hold so much thermal energy.
- The Shelf Break: Look at the narrow strip of light blue along the coasts. This is where the biological action happens. This is where the cold Arctic water meets the nutrients from the deep, making it a prime spot for commercial fishing, specifically for Greenland Halibut and Northern Shrimp.
- The Current Flow: Remember the "counter-clockwise" rule. Everything in Baffin Bay moves in a circle. Water goes up the right side (Greenland) and comes down the left side (Canada).
Realities of Modern Exploration
You can't talk about Baffin Bay without talking about the "Baffin Bay Oil Spill" fears. Because the bay is so enclosed, a major spill would be catastrophic. The currents would just swirl the oil around the basin rather than flushing it out into the open ocean.

Scientists from the University of Manitoba and various Danish research institutes are constantly monitoring the salinity levels here. Why? Because as Greenland’s ice sheet melts, it pours fresh water into Baffin Bay. Fresh water is less dense than salt water. If you dump too much fresh water into the bay, it can actually "cap" the ocean, preventing the normal vertical mixing of nutrients and messing with the North Atlantic Current further south.
It’s a literal tipping point.
Actionable Insights for the Curious
If you’re genuinely interested in Baffin Bay, don't just stare at a static Google Map. The Arctic is too dynamic for that.
Track the Ice in Real-Time Check out the Canadian Ice Service (CIS) or the National Snow and Ice Data Center (NSIDC). They provide daily satellite overlays. Watching the ice bridge in the Nares Strait shatter in the spring is wild. It looks like a slow-motion explosion from space.
Use Bathymetric Tools Use a tool like GEBCO (General Bathymetric Chart of the Oceans). It gives you a 3D-style view of the underwater mountains and canyons that define Baffin Bay. You’ll see that the "bay" is actually a massive mountain range submerged in water.
Support Arctic Sovereignty Research Look into the work of Inuit Tapiriit Kanatami (ITK). They provide the most accurate perspective on how the geography of Baffin Bay is inseparable from the people who live there. Mapping isn't just about coordinates; it's about use and occupancy.
Understand the Migration Corridors If you’re a bird watcher or a marine mammal enthusiast, overlay a map of "Ecologically and Biologically Significant Areas" (EBSAs) onto Baffin Bay. You’ll realize that the western side of the bay is basically a highway for bowhead whales and narwhals moving between their summer and winter grounds.
Baffin Bay isn't just a gap on the globe. It’s a complex, high-stakes environment where the future of the planet is currently being written. Finding it on a map is the first step. Understanding the forces that move its waters is the real challenge.
Next Steps for Deepening Your Knowledge:
- Study the Davis Strait sill, which is the underwater ridge that partially "plugs" the southern end of the bay.
- Research the Middle Ice, a specific zone of thick pack ice in the center of the bay that has frustrated sailors for 400 years.
- Compare historical maps from the 1800s to modern satellite imagery to see just how much the "glacier fronts" on the Greenland side have retreated.
