Floes, the marginal ice zone and coupled wave-sea-ice feedbacks
1The University of Auckland, Auckland, New Zealand.
Summary
Marginal ice zones (MIZs) are dynamic sea ice regions. Understanding floe size distribution (FSD) is key to their study, especially the impact of ocean waves on MIZ dynamics.
Area of Science:
- * Polar Science
- * Oceanography
- * Sea Ice Physics
Background:
- * Marginal ice zones (MIZs) are critical interfaces between polar oceans and the Earth system.
- * MIZs exhibit high variability in oceanic, atmospheric, and ecological conditions.
- * Their structure is a mosaic of ice floes, making floe size distribution (FSD) a key descriptor.
Purpose of the Study:
- * To review the history of floe size distribution (FSD) observations and theory in MIZs.
- * To examine the processes, particularly ocean waves, that influence floe size.
- * To explore coupled wave-FSD feedbacks and identify open questions in MIZ dynamics.
Main Methods:
- * Literature review of FSD observations and theory.
- * Analysis of processes impacting floe size, emphasizing ocean wave effects.
- * Stochastic modeling of thermodynamic wave-sea ice interactions in MIZs.
Main Results:
- * Floe size distribution (FSD) is a quantitative tool for MIZ characterization.
- * Ocean waves significantly influence the size and distribution of ice floes.
- * Coupled wave-FSD feedbacks are crucial for understanding MIZ dynamics.
Conclusions:
- * FSD is fundamental to understanding MIZ structure and behavior.
- * Ocean wave impacts on MIZs require further investigation.
- * This research highlights key areas for future study in a rapidly advancing field.

02:39Phase Transitions: Melting and Freezing
12.7K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

3.6K
A thermodynamic process that occurs at constant volume is called an isochoric process. According to the first law of thermodynamics, heat supplied or removed from the system is partially utilized to perform work and change the internal energy of the system. However, in an isochoric process, the volume remains constant. Hence, the work done by the system is zero. Therefore, the exchange of heat changes the internal energy of the system only.

A thermodynamic process that occurs at constant temperature is called an isothermal process. Heat slowly flows into the system or out of the system to maintain thermal equilibrium. Processes involving phase changes like water evaporation into steam or freezing water into ice at a constant temperature are examples of Isothermal Processes.

01:27Frost Action on Concrete
136
Concrete structures in cold climates, such as those along roadsides, can retain moisture. This moisture makes them susceptible to frost-related damage when temperatures fall below freezing. Adding moisture worsens the damage during temperature fluctuations, leading to repeated freezing and thawing. De-icing salts, spread over these structures to melt ice, add to the freeze-thaw cycle, and draw even more moisture into the concrete.

154.9K
Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.
