Short summary
The Southern Ocean influences global climate, in part, through biological production of carbon-rich particles which trap atmospheric CO2 in the deep ocean. Our study highlights that krill defecating at 50–100 m and injecting carbon-rich pellets effectively counteracts the "typical" scenario where the quantity of particles rapidly decreases from the surface, ultimately increasing how much atmospheric carbon is stored. These processes are of global benefit, but vulnerable in a changing climate.

Warm ocean water causes rapid melting of Antarctic glaciers. The circulation and mixing of warm water in ice shelf cavities is mostly unknown. We observed ocean currents and mixing under Dotson Ice Shelf. Mixing is low, with patches of higher mixing associated with stronger currents and vertical current shear. The levels of turbulent mixing will lead to negligible heat loss during the path of the warm water to the grounding line, leaving plenty of heat available to melt the ice shelf there.

Atlantic Water (AW) delivers heat to glaciers in Greenland, thereby causing melt. We reveal a cooling of the AW entering the world's largest fjord system, Kangertittivaq (East Greenland), after 2018. The cooling is present on the entire Northeast Greenland shelf, driven by cooling in the Nordic Seas. In the fjord, summertime glacier meltwater drives the flow of AW towards the prominent Daugaard Jensen Glacier. The cooling is as strong as the warming of AW at the fjord over the past half century.

The Greenland Ice Sheet is an important contributor to global sea level rise. In northern Greenland, floating glacier tongues are primarily melted by ocean currents. These processes are difficult to observe, so we developed a realistic numerical model to study ocean-driven melting at Greenland's largest floating ice tongue, the 79° North Glacier. Our simulation reveals the details of the oceanic currents bringing warm water toward the ice base, melting and shaping the glacier tongue from below.

The East Greenland Current carries cold, fresh water and sea ice from the Arctic toward the North Atlantic. Using seven years of ocean measurements off northeast Greenland, we found that the current occasionally develops a northward component on the continental slope that can persist for weeks. These events are driven by specific wind patterns that reorganise the current and push warm water into the Arctic — a previously unknown heat pathway, which has regional consequences for sea ice.

Short summary
Phytoplankton blooms near South Georgia are linked to iron-rich waters, but the pathways are unclear. During a research voyage, we measured currents, temperature, and nutrients in two fjords and nearby shelf waters. We found that winds, underwater landscape, and local circulation control how water and nutrients move. Slow exchange within fjords and strong mixing at their mouths suggest these areas can release nutrients that help sustain blooms in the open ocean.

During a year-long Arctic expedition, we discovered nine underwater eddies beneath the sea ice in the central Arctic Ocean. These hidden structures form within a layered part of the ocean just below the surface and may reshape water layers and transport heat, freshwater, and nutrients. Using drifting ice platforms, we measured their size, depth, and motion to understand how they form.

Short summary
The Greenland Ice Sheet represents the second-largest contributor to global sea-level rise. We quantify atmosphere, ice and ocean processes related to the mass balance of glaciers in northeast Greenland, focusing on Greenland’s largest floating ice tongue, the 79° N Glacier. We find that together, the different in situ and remote sensing observations and model simulations reveal a consistent picture of a coupled atmosphere–ice sheet–ocean system that has entered a phase of major change.

Short summary
The southeastern Weddell Sea is important for global ocean circulation due to the cross-shelf-break exchange of Dense Shelf Water and Warm Deep Water, but their exact circulation pathways remain elusive. Using Lagrangian model experiments in an eddy-permitting ocean model, we show how present circulation pathways and transit times of these water masses on the continental shelf are altered by 21st-century climate change, which has implications for local ice-shelf basal melt rates and ecosystems.

Short summary
In the Fram Strait, Arctic Ocean outflow is joined by Atlantic Water (AW) that has not flowed through the Arctic Ocean. The confluence creates a density gradient which steepens and draws closer to the east Greenland shelf break from N to S. This brings the warm AW closer to the shelf break. South of 79° N, AW has reached the shelf break and the East Greenland Current has formed.

In the Fram Strait, Arctic Ocean outflow is joined by Atlantic Water (AW) that has not flowed...
