Sea ice is a critical component of the Earth's climate system, playing a crucial role in global energy balance and the functioning of marine ecosystems. It consists of frozen seawater that forms and melts in polar regions, primarily in the Arctic and Antarctic. Research on sea ice involves studying its physical properties, formation and melting processes, distribution patterns, and impact on weather and climate. Scientists use a variety of tools and methods, including satellites, buoys, and field measurements, to monitor and study changes in sea ice extent, thickness, and volume over time. Understanding sea ice dynamics is essential for predicting future climate trends and assessing the potential consequences of Arctic and Antarctic sea ice loss.
