Nuuk, Greenland: Submarine Cable Landing Point

Nuuk is the capital city of Greenland, an autonomous territory of Denmark situated on the island's southwestern coast. As Greenland's largest urban centre and seat of government, Nuuk is also the territory's most significant node in its submarine cable network. Two submarine cables land at Nuuk, making it the most connected landing point in Greenland and the only location in the territory served by more than one cable.

The two cables landing at Nuuk together enable connectivity across distinct corridors. Greenland Connect links Nuuk into a broader North Atlantic corridor connecting Greenland with Canada and Iceland, while Greenland Connect North serves an entirely domestic route, connecting multiple points within Greenland itself. Together, these two cables give Nuuk both an international gateway function and a central role in Greenland's internal submarine network.

Cables Landing at Nuuk

Greenland Connect is a 4,580-kilometre submarine cable that entered service in 2009, making it the first submarine cable to land in Greenland. The cable connects Greenland with Canada and Iceland, establishing a North Atlantic link that ties Nuuk into international connectivity for the first time through submarine infrastructure. Greenland Connect runs between multiple landing points across these three countries.

Greenland Connect North is a substantially shorter cable at 680 kilometres, which entered service in 2017. This cable connects landing points entirely within Greenland, making it a domestic inter-community route. Greenland Connect North allows Nuuk to serve as a hub distributing connectivity to other Greenlandic communities through submarine cable rather than relying solely on terrestrial or satellite means.

Regional Context

Nuuk stands apart from Greenland's four other submarine cable landing points — Aasiaat, Maniitsoq, Qaqortoq, and Sisimiut — each of which is served by only a single cable. With two cables, Nuuk is the only multi-cable landing point in Greenland and anchors the territory's submarine cable infrastructure. Its combination of an international cable and a domestic cable makes its connectivity profile unique among Greenlandic landing points.

Network Role

Nuuk functions as Greenland's primary submarine cable hub, serving simultaneously as the territory's international gateway and a domestic distribution point. Greenland Connect extends the city's reach across the North Atlantic to Canada and Iceland, while Greenland Connect North ties Nuuk into an intra-Greenlandic cable network. No other landing point in Greenland combines both of these roles.

In the broader regional submarine cable graph, Nuuk's dual-cable status — the only such configuration in Greenland — positions the capital as the single point where international and domestic submarine cable connectivity converge for the territory. This concentration of both cable types at one location reflects Nuuk's standing as Greenland's principal urban and administrative centre.
