Svalbard Glacier Comparisons: What the Historic and 2002 Photographs Reveal

At first, the mountains make these photographs look familiar. Then your eye reaches the waterline, and the difference becomes clear: places once filled by glacier ice have opened into water and exposed ground.

Swedish photographer Christian Åslund created this Svalbard comparison series using historical photographs from the Norwegian Polar Institute alongside views he photographed in 2002. The dates matter. The colour images in this gallery are from an earlier project, not a record of conditions today. See the photographer’s 2002 Svalbard collection for the original project context.

Seven views of a changing glacier landscape

In each pair below, the historical photograph appears above the 2002 image. Follow the mountain ridges and headlands first; they help you compare the position of the ice. The gallery does not provide the individual archive dates.

What comparison photographs can tell us

Repeat photography makes a large change easier to understand. A familiar ridge gives the eye an anchor, while an ice front in a different position reveals a landscape that has changed between exposures. People and boats provide scale, but they are not measuring instruments.

For a careful comparison, look beyond how dramatic the pictures feel:

• Dates and season: seasonal snow can change the appearance of rock and ice.
• Viewpoint: a different camera position or focal length changes apparent distances.
• Ice boundaries: distinguish a glacier front from loose floating ice in the water.
• Supporting measurements: a photograph alone cannot calculate total ice-volume loss or separate every cause of a glacier’s movement.

What newer research adds

A glacier’s mass balance compares how much ice it gains with how much it loses. Researchers combine field observations, remote sensing and modelling to study that change across a region, rather than relying on one striking viewpoint.

A 2025 study of Svalbard’s exceptional 2024 summer estimated summer glacier mass loss at approximately 61.7 ± 11.1 billion tonnes—about 1% of the archipelago’s total ice volume. The study linked the exceptional melt to a prolonged period of unusually high temperatures and atmospheric conditions that supplied substantial energy for melting. Those are regional estimates for a defined period, not measurements calculated from the seven photographs above.

Åslund also returned to the subject with a 2024 glacier comparison project. Following that later work gives the original gallery a useful next chapter without relabelling old photographs as new.

Glaciers, icebergs and lake ice are different stories

The distinctions make winter landscapes more interesting to read. A glacier is a persistent body of land ice that moves under its own weight; an iceberg is a floating piece broken from glacial ice. A frozen lake has a seasonal surface cover formed from the water beneath it.

You can explore those differences in our Ferryland iceberg photo story and Lake Baikal winter photography feature. Here in Svalbard, the lasting value of the paired photographs is the invitation to look carefully—and then connect what we see with what scientists can measure.
