These surveys are fundamental to improving our ability to predict the future of Antarctica, but other data-analysis challenges emerge because surveys often do not agree, large data gaps remain, the ice thickness changes or interpolation works well for one landscape but not another. Similar problems afflict other key Bedmap components: the coastline, the grounding line, rock outcrops, the ice shelves and the bathymetry. The process of merging the interpolated ice sheets and shelves and the grounded bed with the sea floor can also inject spurious cliffs and bumps in the grounding zone-exactly where ice-sheet models are most sensitive to flaws in their boundary conditions. In each case, unintended errors and artefacts that arise in the Bedmap grids require careful checking, correction and sometimes bespoke, local approaches to interpolation, slowing the process further. Here, I highlight the key challenges to overcome and address the question of how future Bedmaps can be automated to speed up the supply of new datasets demanded by the ice-sheet modelling community.

This paper reviews this technique ('radar swath imaging'), explores its methodological principles, describes its operational requirements and highlights recent scientific advances enabled by radar swath imaging. Observations of glacier and substrate morphology and physical properties inferred from swath data have already been used to improve our understanding of ice-shelf melt, basal sliding and subglacial sediment and water transport.

This paper assesses the likelihood of lower IPCC sea-level rise scenarios (SSP1-1.9 and SSP1-2.6) in light of current ice-sheet observations and model limitations, alongside today's emissions trends and current shortfall of climate commitments. We conclude that 'low-end' projections may underestimate the true pace and magnitude of future sea-level rise and, if we continue on today's mid-higher emissions pathway (SSP3-7.0), sea-level outcomes of more than 1 m by 2100 should be planned for. The worst can still be avoided through rapid deep emissions reductions, but it is essential that the IPCC continues to reflect these true risks for decision-makers, with rises of more than 2 m this century and several metres thereafter a real possibility.

The impact of such uncertainties on ice flow simulations of the Antarctic evolution, however, has received little attention. Here, we investigate their impact on the Antarctic evolution at the continental scale as well as the regional scale for the Bellingshausen and Aurora basins and compare them to the impact of climate forcing scenarios. Using error estimates reported in BedMachine Antarctica, our simulations show that bed topography affects the Antarctic contribution to sea level by more than 40 cm in 2150 and 1 m by 2300, comparable to changes caused by different emission scenarios. Variations in grounding line retreat and mass loss are especially important in the Amundsen Sea, Ross and Filchner-Ronne basins. The impact of bedrock uncertainties is even larger on regional- and glacier-scale simulations with a higher spatial resolution, resulting in more variations in grounding line positions and mass change. Overall, these results suggest that errors in bedrock elevation under the Antarctic Ice Sheet are a critical but underexplored source of uncertainty. Additional observations in critical regions are needed to help reduce these systemic uncertainties.

The ice mass flux through the grounding line contributes to global sea-level rise, and the freshwater flux impacts ocean salinity. This narrow zone-where the grounded ice sheet transitions into a floating shelf-is challenging to observe and model because of the remoteness of ice sheet beds and ice shelf cavities and is thus poorly understood. However, our understanding of grounding zones has changed as we collect new observations, which are revealing a far more complex system than previously thought. These observations serve as the foundation for mathematical and numerical models of ice sheets. Models have progressed from simply representing the grounding line as hydrostatic equilibrium and treating ice flow as a viscous fluid to solving visco-elastic problems, including coupled ice sheet-subglacial hydrological models and complex grounding zones. What all these models, however, have in common is the need to know the shape of the bedrock and basal conditions beneath the grounded ice, making a targeted observational campaign of bedrock in current and future possible grounding zones key to fully understanding the Antarctic ice sheet.

In recent years, metal-organic frameworks (MOFs) have been widely studied and used in the field of electrolysed water. Due to their large specific surface area, flexible and adjustable structure, abundant pores and uniform distribution of active sites, MOFs have shown a good electrocatalytic performance. One of the important ways to enhance the electrocatalytic kinetics is to build rich heterostructures to enhance the electrical conductivity, the number and stability of active sites and improve the adsorption/desorption of intermediate substances. In this review, we examine recent advances in the hydrogen evolution reaction and oxygen evolution reaction performance of MOFs modified through synthetic heterostructures and interface engineering. Moreover, the synthesis method, modification mechanism and influence on the activity of MOFs are described. Finally, we highlight current challenges and offer perspectives of MOFs with heterogeneous structures as electrocatalysts in practical applications.

By virtue of Ni-modified AlOOH nanoflowers as starting materials, secondary adsorption and thermal treatment transform the composite into Co/Cu coupled with NiO-modified Al2O3 nanoflowers. The results indicate that the Ni-modification improves the structural properties of AlOOH and regulates the morphology, while calcination treatment contributes to the surface area enlargement and hierarchical pore structure formation, which benefits the diffusion and accessibility of reactant molecules approaching reactive sites. The secondary introduced metal, including Cu/Co, affords a well-dispersed state close to the in situ formed NiO over the Al2O3 nanoflowers. It was found that the Co-modified catalyst Al2O3(Ni)-Cu exhibited the highest styrene conversion rate and styrene oxide selectivity compared to the Co-modified Al2O3(Ni)-Co and Al2O3(Ni). In addition, Al2O3(Ni)-Cu further showcases the great potential in the selective benzene oxidation to benzoquinone, in which benzene conversion reaches 60% at 10 h, and the benzoquinone selectivity was more than 90%, with near 1448 μmol yield.

Diffuse-reflectance Fourier transform (FT-IR) spectroscopic measurements at 30°C, undertaken within a low-coverage regime, indicate aniline adsorption to occur in a parallel orientation with respect to the metal at the support/Pd interface. At higher coverages, aniline adsorption shifts to the alumina support. Temperature-programmed (TP-IR) spectroscopic measurements indicate that the adsorption strength of aniline partitioned between four adsorption sites to follow the trend: support/Pd interface < type III tri-bridged hydroxyls < type IIa bridged hydroxyls ≈ type IIb bridged hydroxyls. Computational (density functional theory (DFT)) studies concentrating on the geometry of the Pd-aniline adsorption complex in the low-coverage regime discern the parallel orientation to be the preferred structure, in agreement with the IR spectroscopic studies. The aniline adsorption in a parallel orientation with respect to the metal surface at the support/Pd interface positions the aromatic ring parallel with the active Pd surface, thereby enabling hydrogenation to cyclohexylamine, the first over-hydrogenation product associated with aniline. The predominant re-adsorption of aniline to the γ-Al2O3 support is proposed to limit product over-hydrogenation in nitrobenzene hydrogenation and, thus, contributes to the reported elevated aniline selectivity over Pd/Al2O3 catalysts.
