Arctic regimes. Currently, warming accelerates the erosion of permafrost coasts and the
associated discharge of sediment, carbon, and nutrients into the Arctic Ocean. However, the …

Benthic food‐web structure and organic matter (OM) utilization are important for marine
ecosystem functioning. In response to environmental changes related to the ongoing climate …

Microbial communities and nutrient dynamics in glaciers and ice sheets continuously
change as the hydrological conditions within and on the ice change. Glaciers and ice sheets …

Diel vertical migration (DVM) is a widespread phenomenon in aquatic environments. The
primary hypothesis explaining DVM is the predation‐avoidance hypothesis, which suggests …

With climate warming, many tidewater glaciers are retreating. Fresh, sediment-rich sub-
glacial meltwater is discharged at the glacier grounding line, where it mixes with deep …

Meltwater runoff from glaciers carries particles, so-called glacial flour that may affect
planktonic organisms and the functioning of marine ecosystems. Protist microplankton is at …

In polar regions, the release of glacial meltwater resulting in turbid plumes is expected to
transform coastal waters with numerous consequences on the marine ecosystem. This study …

1 BACKGROUND The cryosphere covers a relevant portion of the Earth's surface, playing a
major role for terrestrial and marine biomes (Bosson et al., 2023; Sands et al., 2023; Anesio …

Climate change is opening the Arctic Ocean to increasing human impact and ecosystem
changes. Arctic fjords, the region's most productive ecosystems, are sustained by a diverse …

Arctic fjords are hotspots of marine carbon burial, with diatoms playing an essential role in
the biological carbon pump. Under the background of global warming, the proportion of …
