The map, animation and graph illustrate the sea ice thickness in the Northern Hemisphere, excluding the Baltic Sea and the Pacific. The data is based on DMI ’s model calculations. The …

Sea ice thickness determines a number of important fluxes such as heat flux between the air and ocean surface—see below—as well as salt and fresh water fluxes between the ocean since …

Sea ice thickness data is necessary for assessing sea ice mass balance, the surface energy budget, seasonal and annual sea ice prediction, and changes in the polar climate system. …

Nov 16, 2022 · Sea ice can be as thick as a one-story house, depending on how long it has existed. Measuring sea ice thickness is harder than measuring how much sea ice covers the …

Nilas designates a sea ice crust up to 10 centimetres (3.9 in) in thickness. It bends without breaking around waves and swells. Nilas can be further subdivided into dark nilas – up to 5 cm …

Current Arctic sea ice thickness (interpolated and smoothed field) derived from ICESat-2 (L4 Monthly Gridded Sea Ice Thickness, Version 3; Petty et al. 2023) and its difference compared …

Sea ice thickness and volume. Estimates of sea ice thickness from satellite altimetry are used to more directly track this important metric of sea ice conditions, although the satellite altimeter …

Apr 1, 2025 · Globally, the minimum and maximum sea ice extents are about 10 million square km and 28 million square km, respectively. Measured routinely using data obtained from orbiting …

Nov 22, 2010 · Although sea ice begins as a thin layer floating on top of the water, it can grow to be several meters thick depending on a number of different conditions involving what's …

The thickness of the sea ice shapes a range of key parameters, like thermal flux between the atmosphere and the ocean’s surface, as well as the exchange of freshwater and saltwater …
