Short summary
Short summary
Using ambient seismic noise at a long-running array on Svalbard, we show that small changes in ground velocity follow seasonal freezing and thawing in shallow permafrost. Velocity increases when the ground cools and decreases after summer thaw, in step with borehole temperature near the base of the active layer. A slow decrease over three decades is consistent with Arctic warming and a gradual loss of ice-bonded stiffness, and shows that permanent seismic stations can monitor permafrost.

We have investigated a long-term record of ground vibrations, recorded by a seismic array installed in Adventdalen, Svalbard. This record contains a large number of
frost quakes, a type of ground shaking that can be produced by cracks that form as the ground cools rapidly. We use underground temperatures measured in a nearby borehole to model forces of thermal expansion and contraction that can cause these cracks. We also use the seismic measurements to estimate where these cracks occurred.

Short summary
The Gulf Stream carries warm water northward and affects climate. Scientists disagree about whether it is weakening. Using Argo floats from 2003 to 2024, we separated the fast core from the slower surrounding water across the current's width. The core remained stable, while the surrounding water weakened before 2017 and recovered afterward, changing the core's share of transport. This shows the current is not changing uniformly, explaining why studies report different trends.

Understanding the glacier response to accelerated climate warming in the Arctic requires data obtained in the field. Here, we present a dataset of velocity measurements of Hansbreen, a tidewater glacier in Svalbard. The glacier's velocity was measured with GPS at 16 stakes mounted on the glacier's surface. The measurements were conducted from about 1 week to about 1 month. The dataset offers unique material for validating numerical models of glacier dynamics and satellite-derived products.

In our research, we evaluate the potential of archival maps of Hornsund fjord area, southern Spitsbergen, published by the Polish Academy of Sciences for studying glacier changes. Our analysis concerning glaciers in the north-western part of the Sørkapp Land peninsula revealed that, in the period 1961–2010, a maximum lowering of their surface was about 100 m for the largest land-terminating glaciers and over 120 m for glaciers terminating in the ocean (above the line marking their 1984 extents).

Glaciers which end in bodies of water can lose mass through melting below the waterline, as well as by the breaking off of icebergs. We use a numerical model to simulate the breaking off of icebergs at Kronebreen, a glacier in Svalbard, and find that both melting below the waterline and tides are important for iceberg production. In addition, we compare the modelled glacier front to observations and show that melting below the waterline can lead to undercuts of up to around 25 m.

The terminus of San Quintín glacier, the largest of the Northern Patagonia Icefield in southern Chile, is rapidly disintegrating with large tabular icebergs into a proglacial lake left behind by this retreating glacier. We show that the ongoing retreat is caused by recent detachment of a floating terminus from the glacier bed. This process may lead to the disappearance of the last existing piedmont lobe in Patagonia, and one of the few remaining glaciers of this type in the world.

Short summary
Ice loss at the front of glaciers can be observed with high temporal resolution using seismometers. We combine seismic and underwater sound measurements of iceberg calving at Kronebreen, a glacier in Svalbard, with laser scanning of the glacier front. We develop a method to determine calving ice loss directly from seismic and underwater calving signals. This allowed us to quantify the contribution of calving to the total ice loss at the glacier front, which also includes underwater melting.
