Summary: This study numerically investigates the melting process of a solid layer heated from below and finds that thermal convection leads to increased roughness of the interface, which is coupled to the flow topology. The structure of the interface coincides with the regions of rising hot plumes and descending cold plumes, and the roughness amplitude scales with the mean height of the liquid layer.

Summary: Iceberg calving, responsible for 50% of ice discharge from Greenland and Antarctic ice sheets, has significantly increased in the past two decades. The displacement and melt of icebergs have impacts on regional and global ocean circulation and marine ecosystems, affecting their stratification, nutrient and carbon cycling. The fresh meltwater from icebergs can influence regional sea ice distribution and global overturning circulation. However, our understanding of iceberg melting is limited, and current ocean and climate models oversimplify their representation due to a lack of observations. Consequently, model-based predictions of iceberg melt rates, meltwater fate, and their impact on the ocean are highly uncertain. Further observational, modeling, and experimental studies are crucial to enhancing our understanding of iceberg melting and improving the forecasting capabilities of climate models.

Summary: Sea ice is vital in natural processes and human activities. We conducted experiments to study the freezing process of saltwater in a natural convection system and found that it is more complex than the freezing of fresh water under the same conditions. We measured the ice thickness and porosity at the equilibrium state and identified different modes of heat transport. A one-dimensional multi-layer heat flux model was proposed to predict ice thickness based on measured porosity.

Summary: This study conducts numerical simulations for double-diffusive convection in the diffusive regime, and finds that staircase-like structures can spontaneously develop under certain conditions. Different initial perturbations lead to different layered states, which are significantly influenced by shear. The density flux ratio is found to be related to the square root of the ratio between salt diffusivity and thermal diffusivity.

Summary: We investigated the shape dynamics of ice in cold fresh water during the melting process. Experimental and phase-field simulation results showed that as the cooling rate increased, the shape of the ice changed from downward sharp pinnacles, to scalloped waves at intermediate temperatures, and finally to upward pointing pinnacles at higher temperatures. These shape changes were closely linked to the density-temperature profile of water.

Summary: In this study, the combined effects of buoyancy, pressure-driven shear, and rotation on the melt rate and morphology of a layer of solid overlying its liquid phase were investigated through well-resolved numerical simulations. The results showed a non-monotonic relationship between the melting rate of the solid phase and the strength of the imposed shear flow. The geometry of the phase boundary was found to have significant effects on the heat flux in the liquid layer. Rotation was observed to change the direction of the mean flow and the geometry of the solid-liquid interface.

Summary: This study investigates the melting behavior of ice in vertical convection and reveals an abrupt transition in the melting rate as the heating temperature increases. The emergence of a reversed buoyant flow due to the density anomaly of water near the melting point is responsible for this transition.

Summary: We conducted an idealized numerical study on melting and freezing solid adjacent to turbulent, buoyancy-affected shear flow. The results show that channels generated at the fluid-solid interface align with the direction of the mean flow and vary significantly under different density stratification.

Summary: In this study, the numerical investigation of melting process in a convecting layer of fluid rotating about a vertical axis above a solid layer revealed various characteristics of fluid convection under rotation. The relationship between melting rate and fluid properties was found to be influenced by the rotating conditions. The findings suggest that changes in different parameters can affect the details of the melting process under specific conditions.

Summary: Efficient statistical emulation of melting land ice under various climate scenarios to 2100 indicates a contribution of at least 13 centimetres sea level equivalent. Limiting global warming to 1.5 degrees Celsius would halve the land ice contribution to twenty-first-century sea level rise, with glaciers responsible for half the sea level contribution. Uncertainties in the Antarctic contribution suggest a factor-of-three uncertainty in the land ice contribution until climate policies and the Antarctic response are further constrained.

Summary: The study investigates the Rayleigh-Benard-Poiseuille flow over an evolving phase boundary using numerical simulations. The results show that Poiseuille flow inhibits convective motion, leading to heat transport primarily through conduction, while for Ri(b) >> 1, flow properties and heat transport closely resemble the purely convective case. In certain conditions, there is pattern competition for convection cells with a preferred aspect ratio. Additionally, traveling waves at the solid-liquid interface are observed when Pe is not equal to 0, in agreement with experimental findings and linear stability analysis.

Summary: The study investigates the extent and morphology of ice formation in a cavity filled with water under differentially heated conditions using experiments and numerical simulations. The main mechanism driving ice shaping is identified as the presence of a cold upward convective current in the system, attributed to the peculiar equation of state of water. Factors such as temperature difference across the cell and wall inclination are explored to determine the precise form of the ice front, with proposed boundary-layer and buoyancy-intensity models explaining the main features of ice morphology.
