How much shorter is the Arctic northeast waterway than the traditional waterway?

When this concept was put forward, it was basically impossible to cross the new island from Murmansk, but in the last two years, several schemes have been put forward and passed smoothly, including Norway and not (excluding Rotterdam outside the Arctic Ocean). , or the Baltic route, because this part has been in use and does not belong to the new channel).

The starting port of the route includes Tromso, Norway, stopping at Longyearbyen, Svalbard, and then going to the highest latitude of 87-88 (reaching the highest latitude just above the meridian where severnaya zemlya is located, and then gradually descending, severnaya zemlya now has a new reclamation supply area), and then from the high latitude, it goes all the way through the latitude to Ullen at 66 north latitude, and then through the Bering Strait to Anadel, along the kamchatka peninsula. From east to west, and vice versa.

The key to shorten the distance lies in the northeast corner of Svalbard-URI En (Franz Josef Islands also), which can completely cross 88 north latitude (the North Pole is 90 north latitude). This distance is only over 3,700 kilometers, but the longitude of the span exceeds 180, because the earth is not flat, but spherical, at the latitude above 80 north latitude. . It is far from the straight line crossing with more than 180 on the equator. Even a straight line near the equator is half the circumference of the equator, more than 20 thousand kilometers. Considering the winding coastline, it is not a random calculation.

There are many routes in Russian waters, only the longest and shortest routes:

The latitude is extremely high, and the starting port is the new reclamation area of Alexandria in Murmansk-Franz Josef Islands, and the distance behind it is the same. It is also directly above the meridian where severnaya zemlya is located, and it reaches 87-88 north latitude, and the distance after that is the same.

The original conceptual route is middle and high latitudes, and the total distance is much longer, which is the longest. The starting point is still Murmansk-the southern tip of Xindi Island-Yamal Peninsula-Chelyushkin Point, crossing the Vilykitsky Strait and reaching Tixi-Pevek-Ulun, and the distance after that is the same.
