Tidewater glaciers play a central role in polar dynamics, but their study is limited by harsh and isolated conditions. Here, we introduce broadband echosounders as an tool for the study of high latitude fjords through the rapid collection of calibrated high resolution, near-synoptic observations. Using a data set collected in Hornsund fjord we illustrate the potential of broadband echosounders as a relatively low-cost, low-effort tool, well suited for field deployment in high-latitude fjords.

Since 2015, temperature and salinity have been monitored in Hornsund fjord (Svalbard), where retreating glaciers add meltwater and terrestrial matter to coastal waters. Therefore, turbidity and water sampling for suspended sediment concentration and sediment deposition are measured. The monitoring spans from May to October, enabling studies on seasonality and its variability over the years, and the dataset covers the whole fjord, including the inner basins in close proximity to the glaciers.

This paper is about a way to make measurements close to small pieces of floating glacier ice. This is done by attaching instruments to the ice from a small boat. Making these measurements will be helpful for the study of the physics that goes on at small scales when glacier ice is in contact with ocean water. Understanding these small-scale physics may ultimately help improve our understanding of how much ice in Greenland and Antarctica will melt as a result of warming oceans.

Short summary
Receding tidewater glaciers are important contributors to sea level rise. Understanding their dynamics and developing models for their attrition has become a matter of global concern. Long-term monitoring of glacier frontal ablation is very difficult. Here we show for the first time that calving fluxes can be estimated from the underwater sounds made by icebergs impacting the sea surface. This development has important application to understanding the response of glaciers to warming oceans.

Over the oceans, sea spray aerosol is an important source of particles that may initiate the formation of cloud ice, which then has implications for the radiative properties of marine clouds. In our study, we focus on marine biogenic particles that are emitted episodically and develop a numerical framework to describe these emissions. We find that further cloud-resolving model studies and targeted observations are needed to fully understand the climate impacts from marine biogenic particles.

The melting of ice mélange, or dense packs of icebergs and sea ice in glacial fjords, can influence the water column by releasing cold fresh water deep under the ocean surface. However, direct observations of this process have remained elusive. We use measurements of ocean temperature, salinity, and velocity bookending an episodic ice mélange event to show that this meltwater input changes the density profile of a glacial fjord and has implications for understanding tidewater glacier change.

The Filchner–Ronne Ice Shelf in Antarctica is susceptible to the intrusion of deep, warm ocean water that could increase the melting at the ice-shelf base by a factor of 10. We show that representing this potential melt regime switch in a low-resolution climate model requires careful treatment of iceberg melting and ocean mixing. We also demonstrate a possible ice-shelf melt domino effect where increased melting of nearby ice shelves can lead to the melt regime switch at Filchner–Ronne.

Icebergs are a mechanism via which the cryosphere and ocean interact. Here we analyzed ice samples from both Arctic and Antarctic polar regions to assess the variability in the composition of calved ice. Our results show that low concentrations of nitrate and phosphate in ice are primarily atmospheric in origin, whereas sediments impart a low concentration of silica and modest concentrations of trace metals, especially iron and manganese.

This study focuses on the Totten and Moscow University ice shelves, East Antarctica. We used an ocean–sea ice–ice shelf model to better understand regional interactions between ocean, sea ice, and ice shelf. We found that a combination of warm ocean water and local sea ice production influences the regional ice shelf basal melting. Furthermore, the model reproduced the summertime undercurrent on the upper continental slope, regulating ocean heat transport onto the continental shelf.

Many outlet glaciers in Greenland are connected to the ocean by narrow glacial fjords, where warm water melts the glacier from underneath. Ocean water is modified in these fjords through processes that are poorly understood, particularly iceberg melt. We use a model to show how iceberg melt cools down Ilulissat Icefjord and causes circulation to take place deeper in the fjord than if there were no icebergs. This causes the glacier to melt less and from a smaller area than without icebergs.

New observations reveal the Thwaites gyre in a habitually ice-covered region in the Amundsen Sea for the first time. This gyre rotates anticlockwise, despite the wind here favouring clockwise gyres like the Pine Island Bay gyre – the only other ocean gyre reported in the Amundsen Sea. We use an ocean model to suggest that sea ice alters the wind stress felt by the ocean and hence determines the gyre direction and strength. These processes may also be applied to other gyres in polar oceans.

One of the questions facing the cryosphere community today is how increasing runoff from the Greenland Ice Sheet impacts marine ecosystems. To address this, long-term data are essential. Here, we present multi-site records of fjord productivity for SW Greenland back to the 19th century. We show a link between historical freshwater runoff and productivity, which is strongest in the inner fjord – influenced by marine-terminating glaciers – where productivity has increased since the late 1990s.

We used an ocean–sea ice–ice shelf model with a 2–3 km horizontal resolution to investigate ocean–ice shelf/glacier interactions in Lützow-Holm Bay, East Antarctica. The numerical model reproduced the observed warm water intrusion along the deep trough in the bay. We examined in detail (1) water mass changes between the upper continental slope and shelf regions and (2) the fast-ice role in the ocean conditions and basal melting at the Shirase Glacier tongue.

Greenland's glaciers in contact with the ocean drain the majority of the ice sheet (GrIS). Deep troughs along the shelf branch into fjords, connecting glaciers with ocean waters. The heat from the ocean entering deep troughs may then accelerate the mass loss. Onshore heat transport through troughs was investigated with an ocean model. Processes that drive the delivery of ocean heat respond differently by region to increasing GrIS meltwater, mean circulation, and filtering out of storms.

Previous studies have shown accelerations of West Antarctic glaciers, implying that basal melt rates of these glaciers were small and increased in the middle of the 20th century. We conduct coupled sea ice–ice shelf–ocean simulations with different levels of ice shelf melting from West Antarctic glaciers. This study reveals how far and how quickly glacial meltwater from ice shelves in the Amundsen and Bellingshausen seas propagates downstream into the Ross Sea and along the East Antarctic coast.

Large tabular icebergs (
ice islands) are symbols of climate change as well as marine hazards. We measured thickness along radar transects over two visits to a 14 km2 Arctic ice island and left automated equipment to monitor surface ablation and thickness over 1 year. We assess variation in thinning rates and calibrate an ice–ocean melt model with field data. Our work contributes to understanding ice island deterioration via logistically complex fieldwork in a remote environment.

Numerical experiments have been performed to study the effect of basal melting of the Ross Ice Shelf on the ocean southward of 35° S. It is shown that the melt rate averaged over the entire Ross Ice Shelf is 0.253 m year-1, which is associated with a freshwater flux of 3150 m3 s-1. The extra freshwater flux decreases the salinity in the Southern Ocean substantially, leading to anomalies in circulation, sea ice, and heat transport in certain parts of the ocean.

Short summary
Marine-terminating glaciers are shrinking rapidly in response to the warming climate and thus provide large quantities of fresh water to the ocean system. However, accurate estimates of ice loss at the ice–ocean boundary are difficult to obtain. Here we demonstrate that ice mass loss from iceberg break-off (calving) can be measured by analyzing the underwater noise generated as icebergs impact the sea surface.
Marine-terminating glaciers are shrinking rapidly in response to the warming climate and thus...
