Arctic Ice Sheet
Arctic Ice Sheet - Web each year, arctic sea ice melts and refreezes with seasonal changes. Web the arctic region is a main area for ice analysis by the u.s. Web new research out of nasa's jet propulsion laboratory in southern california shows that in the central arctic, away from the coasts, fall sea ice now hovers around 4.2 feet (1.3 meters) thick,. If the antarctic ice sheet melted, sea level would rise by about 60 meters (200 feet). Web daily and monthly images and data for both arctic and antarctic sea ice, which illustrate sea ice extent and concentration and how these are changing. Web this visualization shows the expanse of the annual minimum arctic sea ice for each year from 1979 through 2022, with a graph overlay.
It provides consistently processed daily ice extent and concentration images and data since 1979. Web the arctic sea ice minimum likely occurred on 11th september at a value of 4.28 million sq km. Web the 17 lowest arctic sea ice extents on record occurred during the last 17 years. Data for this project come from passive microwave instruments on u.s. Based off these analyses, numerous products are created and disseminated here.
