131 unresolved questions extracted from the limitations and future-work sections of 695 Arctic and Antarctic ice dynamics papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • Sweeping the SLIC construction hyperparameters, - ablating the input channels, - testing operator-graph interactions, - re-tuning the CNN models to the fullest extent

    Graph neural networks for antarctic sea ice concentration forecasting · 2026 · DOI

  • Existing statistical and dynamical approaches struggle to represent the nonlinear and heterogeneous nature of Antarctic sea-ice dynamics. Conventional deep-learning models like CNNs operate on regular Euclidean grids, making long-range spatial dependencies difficult to represent.

  • 3 km over the course of our data set as few areas of extensive landfast remain to be lost.

  • However, the effectiveness of this approach remains uncertain, as numerical models show contrasting results and few field experiments have been conducted.

    Field Observations of Sea Ice Thickening by Artificial Flooding · 2026 · DOI

  • However, due to the sparsity of observations and the complex dependencies of CDW on changes in both the ocean interior and surface conditions, the processes driving its warming in the Southern Ocean remain unclear.

  • However, a pan‐Arctic characterization of Acc and its advantages over V remain elusive.

  • However, the mechanisms driving inter‐model spread in this process remain poorly understood.

    Attribution of the Spread in Antarctic Sea Ice‐Driven Water Mass Transformation in Coupled Climate Models · 2026 · DOI

  • SMOS sea surface salinity (SSS) data were limited to the ice‐free period, and reanalysis outputs showed limited accuracy in capturing the postmelt freshening observed in SMOS SSS.

    Sea Ice Meltwater in the Beaufort Gyre: A Comprehensive Analysis Using Sea Surface Salinity Data From SMOS · 2025 · DOI

  • In summer, the sea surface salinity (SSS) gradient provides a better identification of the PF rather than the sea surface temperature gradient, but the interannual mechanisms driving the PF change remain unclear.

    Interannual Variability of the Polar Front Surface Thermohaline Properties in the Barents Sea · 2025 · DOI

  • However, the changes in nutrient dynamics in and under the sea ice resulting from melt pond formation are poorly understood.

    Melt Pond Nutrient Dynamics and Their Relationship With Melt Pond Bottom Ice in the Central Arctic Ocean · 2025 · DOI

  • However, the links between the SML and seasonal sea ice changes, as well as the dominant mechanisms governing this interaction, remain insufficiently understood.

    Causal Links Among Sources of Heat in the Arctic Surface Mixed Layer and Seasonal Sea Ice Melt · 2025 · DOI

  • However, these processes are still not fully elucidated and are generally poorly represented in state‐of‐the‐art climate models.

    Drivers of the Mixed Layer Salinity Variability in the Seasonal Ice Zone of the Arctic Ocean · 2025 · DOI

  • However, the representation of sea ice in climate models is variable, and its impact on water mass transformation remains unclear.

  • Yet, the fine‐scale structure, variability, and long‐term evolution of its water masses and nutrient concentrations remain poorly characterized.

    Water Mass Assemblages and Nutrient Dynamics in Nares Strait: A Multiyear Perspective · 2025 · DOI

  • Yet the interaction between sea ice and ocean eddies in this region remains poorly understood.

    Anticyclonic Component of Eddy Dipoles Traps Sea Ice Within the Marginal Ice Zone · 2025 · DOI

  • Although Arctic warming and sea ice retreat have been well‐documented, the influence of tropical Atlantic SST on Arctic sea ice remains understudied.

    Impact of Tropical Atlantic Sea Surface Temperature Variability on Boreal Autumn Sea Ice Concentration Over the Beaufort Sea · 2025 · DOI

  • However, recent intrusions remain poorly characterized, and the underlying mechanism(s) and large‐scale precursors are only partly understood.

    Winter Intrusions of Atlantic Water in Kongsfjorden: Oceanic Preconditioning and Atmospheric Triggering · 2024 · DOI

  • The pathways of Atlantic Water within the Arctic Ocean, and in particular their sensitivities to large‐scale atmospheric patterns such as the Arctic Oscillation, remain unclear.

    Decadal Changes in the Pathways of the Atlantic Water Core in the Arctic Ocean Inferred From Transient Tracers · 2024 · DOI

  • Although some mechanisms have been extensively studied in idealized setting, in particular for the dynamics of the Beaufort gyre (BG), it remains unclear how applicable they are to more complex systems.

    Drivers of Interannual Salinity Variability in the Arctic Ocean · 2024 · DOI

  • This challenges the conventional understanding of Baffin Bay's circulation and underscores the need for further research on the region's physical oceanography.
