Remote Sensing, 2022 Salt marshes are vulnerable to sea-level rise, sediment deficits, and storm impacts. To remain vertically resilient, salt marshes must accrete sediment at rates greater or equal to sea-level rise. Ice-rafted debris (IRD), sediment that has been moved and

Mixed ice accretion on aircraft wings [PDF]
, 2018 Ice accretion is a problematic natural phenomenon that an effects a wide range of engineering applications including power cables, radio masts and wind turbines. Accretion on aircraft wings occurs when supercooled water droplets freeze instantaneously on

Altitude Scaling of Ice Crystal Accretion
5th AIAA Atmospheric and Space Environments Conference, 2013 This paper describes experiments performed in an altitude chamber at the National Research Council of Canada (NRC) as the first step towards developing altitude scaling laws and procedures that will possibly allow aero-engines to be certified for operation in ice crystal clouds at high altitude by testing in sea level facilities.

Ice accretion simulations on airfoils [PDF]
Progress in Flight Physics, 2017 Ice shape predictions for a NACA0012 airfoil and collection efficiency predictions for the Twin Otter airfoil are obtained and presented. The results are validated with reference numerical and experimental data. Ice accretion modeling mainly consists of four steps: flow field solution; droplet trajectory calculations; thermodynamic analyses; and ice ...

Greenland Ice Sheet Ice Slab Expansion and Thickening
Geophysical Research Letters, 2023 We use airborne accumulation radar data acquired over the Greenland Ice Sheet between 2002 and 2018 to identify changes in ice slab extent and thickness. We show that ice slabs several meters thick were already present at least as early as 2002.
