2023年12月6日 · Because sea ice is created from seawater, it does not contribute to rising sea levels when it melts. How are scientists studying sea ice? Group Operations Leader John Kemp uses a hook to recover a top float mooring in the Beaufort Sea of the Arctic Ocean to acquire vertical profiles of temperature salinity and velocity in the water column ...
Sea Ice Glossary - Woods Hole Oceanographic Institution
Sea ice which has become honeycombed and is in an advanced state of disintegration. Sastrugi, (sing. sastruga). Sharp, irregular ridges formed on a snow surface by wind erosion and deposition. On mobile floating ice, the ridges are parallel to the direction of the prevailing wind at the time they were formed. Sea ice. Any form of ice found at ...

2024年12月15日 · Understanding the processes that control vertical heat fluxes under the sea ice is important to understand the response of sea ice to a changing climate (Carmack et al., 2015). The interplay between heat and salt exchange at the ice–ocean interface can work to enhance or reduce sea ice melt in the Arctic Ocean (Sirevaag, 2009).

2024年10月30日 · The wintertime loss of Arctic sea ice is most pronounced in the Barents Sea, where a retreating ice cover reflects increased Atlantic inflow locally (Helland-Hansen and Nansen 1909; Smedsrud et al. 2013), and a heat loss increase of 138 W m −2 has been associated with the sea ice retreat (Årthun et al. 2012).
Sea Level Rise - Woods Hole Oceanographic Institution
Sea level rise doesn’t directly impact climate change, but the factors that drive rising seas can accelerate it. Cascading impacts such as these are called feedbacks. The case of sea level rise and melting ice is a positive feedback because this cycle speeds warming; negative feedbacks that slow warming exist too.
