Scoresby Sund: The World's Largest Fjord System

Scoresby Sund (Kangertittivaq in Kalaallisut, the Greenlandic language) is the largest fjord system in the world, located on the eastern coast of Greenland at approximately 70 degrees north latitude. The main fjord stretches over 350 kilometers from the coast to the edge of the Greenland Ice Sheet, with numerous branches that together create a fjord system covering roughly 38,000 square kilometers.

Introduction

Named after the British Arctic explorer William Scoresby Jr., who charted its entrance in 1822, the fjord system contains some of the largest icebergs in the Northern Hemisphere. Its remote, ice-choked waters and extreme Arctic climate make it one of the most challenging environments on Earth, inhabited by polar bears, musk oxen, and a tiny human population clinging to existence at the edge of the habitable world.

Geography & Formation

• Main Fjord Length: 350+ km
• System Area: ~38,000 km²
• Maximum Depth: ~1,450 m
• Latitude: ~70°N

Scoresby Sund dwarfs every other fjord system on Earth. Its main channel stretches over 350 kilometers — longer than all of Norway's fjords except Sognefjorden — and its numerous branches extend the total system to roughly 38,000 square kilometers, an area larger than the Netherlands. The fjord system penetrates deep into Greenland, reaching within 200 kilometers of the ice sheet.

The fjord's maximum depth of approximately 1,450 meters makes it one of the deepest fjords in the world. The mouths of the fjord's outer branches are dotted with massive icebergs calved from the Greenland Ice Sheet's outlet glaciers. Some of these icebergs tower over 100 meters above the waterline and extend several hundred meters below.

Glacial Origins

• Ice Sheet Proximity: Branches reach within ~200 km of Greenland Ice Sheet
• Outlet Glaciers: Daugaard-Jensen, Vestfjord Glacier
• Iceberg Production: Among the largest in the Northern Hemisphere

Scoresby Sund was carved by outlet glaciers flowing from the Greenland Ice Sheet over millions of years. The extreme depth and length of the system reflect the enormous erosive power of these ice streams, which at their peak extended far onto the continental shelf. The fjord's bedrock of ancient gneiss and basalt has been ground smooth by millions of years of glacial action.

The Daugaard-Jensen Glacier, one of the fastest-flowing glaciers in eastern Greenland, calves directly into the inner fjord system, producing icebergs that drift through the fjord over a period of months before reaching the open sea. These icebergs can be massive — some exceed 1 kilometer in length and carry millions of tonnes of ice.

Ecology & Wildlife

• Polar Bears: Significant population in the region
• Musk Oxen: One of the largest populations in Greenland
• Marine Life: Narwhals, ringed seals, Arctic char
• Birds: King eiders, ivory gulls, gyrfalcons

Scoresby Sund is one of the premier wildlife habitats in the Arctic. Polar bears roam the sea ice and shoreline, hunting ringed seals at breathing holes. The fjord system supports one of the largest musk oxen populations in Greenland, with herds grazing on the sparse tundra vegetation during the brief Arctic summer.

Narwhals, the "unicorns of the sea," migrate into the fjord system in summer to feed on Arctic cod and Greenland halibut. The fjord's mix of freshwater from glacial melt and cold saline water creates productive feeding conditions. King eiders, ivory gulls, and the powerful gyrfalcon are among the Arctic bird species that breed in the surrounding mountains and cliffs.

Cultural Heritage

• Settlement: Ittoqqortoormiit (~350 residents)
• Indigenous People: Inuit hunters and fishers
• European Contact: William Scoresby Jr., 1822

Ittoqqortoormiit (formerly Scoresbysund) is the only settlement in the fjord system, home to roughly 350 people — making it one of the most remote communities in the world. The town was established in 1925 when Inuit families from Ammassalik were relocated to settle the region. The residents live primarily from hunting and fishing, following a traditional Arctic subsistence lifestyle.

The Inuit of Ittoqqortoormiit hunt polar bears, seals, musk oxen, and narwhals using methods that blend traditional knowledge with modern equipment. Dog sledding remains a primary form of winter transportation. The community faces an uncertain future as climate change alters sea ice conditions and shifts the distribution of the wildlife they depend on.

Visitor Experience

• Access: Expedition cruise ships or charter flights to Ittoqqortoormiit
• Season: Late July to early September (ice permitting)
• Activities: Iceberg viewing, wildlife watching, dog sledding
• Climate: Harsh; summer temps 0–10°C

Visiting Scoresby Sund is a true expedition experience. The fjord is accessible only during a brief window in late summer when sea ice conditions permit entry by ship. Even then, icebergs and pack ice can block passages, and itineraries must remain flexible. Expedition cruise ships operating from Iceland are the most common way to visit.

The experience of sailing through Scoresby Sund is unlike any other fjord in the world. Titanic icebergs in every shade of white and blue dwarf the ship, while polar bears may be spotted on ice floes and musk oxen graze on distant shores. The scale is almost incomprehensible — you can sail for days and still be within the fjord system.

Key Facts

• Scoresby Sund is the largest fjord system in the world at ~38,000 km².
• The main fjord stretches over 350 km — longer than Sognefjorden.
• Its maximum depth of ~1,450 m makes it one of the deepest fjords on Earth.
• Ittoqqortoormiit, with ~350 residents, is one of the most remote communities in the world.
• Icebergs in the fjord can exceed 1 km in length.

Fun Facts

• The fjord system covers an area larger than the Netherlands.
• Scoresby Sund is so remote that it can only be visited by ship during a few weeks of summer.
• The settlement of Ittoqqortoormiit receives only one or two supply ships per year.
• Narwhals migrating through the fjord use their long tusks (actually a tooth) as sensory organs, not weapons.

Final Thoughts

Scoresby Sund is the fjord concept taken to its ultimate extreme — the largest, deepest, and most remote fjord system on Earth. Its titanic icebergs, polar wildlife, and vast Arctic wilderness represent a landscape that has barely changed since the Ice Age, offering those who make the journey an encounter with nature on a truly planetary scale.
