Frazil Ice in the Antarctic Marginal Ice Zone [PDF]
Journal of Marine Science and Engineering, 2021 Frazil ice, consisting of loose disc-shaped ice crystals, is the first ice that forms in the annual cycle in the marginal ice zone (MIZ) of the Antarctic.

Microstructural Characteristics of Frazil Particles and the Physical Properties of Frazil Ice in the Yellow River, China [PDF]
Crystals, 2021 Frazil particles, ice crystals or slushy granules that form in turbulent water, change the freezing properties of ice to create “frazil ice”. To understand the microstructural characteristics of these particles and the physical properties of frazil ice ...

Frazil ice events: Assessing what to expect in the future
Hydrology Research, 2023 This article addresses the question: What is expected from frazil ice activity in rivers, taking into account the changing climate? It begins with an overview of what frazil ice is and what is required for the occurrence of frazil ice events, namely a ...

Frazil ice formation in an ice shelf water plume [PDF]
Journal of Geophysical Research, 2004 We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow of buoyant water upward along the ice shelf base and includes the differential growth of a range of crystal sizes.

A mathematical model for supercooling process and its application to frazil ice evolution [PDF]
Scientific Reports, 2023 The calculation of the number of ice crystals for the model of frazil ice evolution is very important and affects the whole frazil events. In this paper, the general formula for the number of frazil ice crystals was established considering secondary ...

Biodegradation of weathered crude oil in seawater with frazil ice [PDF]
Marine Pollution Bulletin, 2020 As ice extent in the Arctic is declining, oil and gas activities will increase, with higher risk of oil spills to the marine environment. To determine biotransformation of dispersed weathered oil in newly formed ice, oil dispersions (2-3 ppm) were incubated in a mixture of natural seawater and frazil ice for 125 days at -2 °C. Dispersed oil in seawater

Mapping of Active Frazil for Antarctic Coastal Polynyas, With an Estimation of Sea‐Ice Production
Geophysical Research Letters, 2021 The importance of the area of active frazil and associated high sea‐ice production in Antarctic coastal polynyas has been increasingly recognized in recent in situ and high‐resolution satellite observations.

Observations of the Size Distribution of Frazil Ice in an Ice Shelf Water Plume [PDF]
Geophysical Research Letters, 2020 The size distribution of frazil ice is currently unconstrained in ice shelf cavity modeling. Here we observe the time-dependent behavior of the number and size of frazil ice particles in an Ice Shelf Water plume. A novel acoustic scattering inversion was used to infer frazil ice crystal diameters, assuming a log-normal distribution.

Frazil ice changes winter biogeochemical processes in the Lena River [PDF]
Communications Earth & EnvironmentThe ice-covered period of large Arctic rivers is shortening. To what extent will this affect biogeochemical processing of nutrients? Here we reveal, with silicon isotopes (δ30Si), a key winter pathway for nutrients under river ice.
