The interaction between air, sea, and ice affects weather, climate, and life both below and above the sea surface.<\/p><\/div>[vc_column_text]<\/p>\n<p style=\"text-align: center;\">The air over the Arctic Ocean is very dry and cold, down to -40\u00b0C in winter. The ocean temperature under the ice, on the other hand, is &#8220;only&#8221; -2\u00b0C. The two environments, air and ocean, are very different, and the ice acts as a separation between the two. But the ice is not solid, like a lid. It moves, and is continuously pushed and pulled by wind, ocean currents, and waves. This causes the ice to crack open or be compressed. Storms coming in over the Arctic Ocean will have a major impact on this dynamic. When cold and dry air is exposed to relatively warm water in a crack in the ice, the air will quickly heat up and get more moist as water evaporates. This affects wind and precipitation. In the spring, openings in the ice will let in light, which provides fertile ground for algae growth and bustling wildlife. We use high-resolution satellite images in combination with the sea-ice model &#8220;neXtSIM&#8221; to look at the interaction between air, sea, and ice, and how these processes affect the environment and climate.<\/p>\n<p>[\/vc_column_text]<div class=\"spacer\" style=\"--space-sm: 15px;--space-md: 15px;--space-lg: 15px;--space-xl: 15px;\"><\/div><div class=\"infobox teal\">\n<p style=\"text-align: center;\">For more information, contact <a href=\"https:\/\/nersc.no\/en\/ansatt\/einar-olason\/\"><strong>research leader Einar \u00d3lason<\/strong><\/a>.<\/p>\n<\/div><div class=\"spacer\" style=\"--space-sm: 15px;--space-md: 15px;--space-lg: 15px;--space-xl: 15px;\"><\/div>[\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][\/vc_section][vc_row][vc_column]<div class=\"spacer\" style=\"--space-sm: 30px;--space-md: 30px;--space-lg: 30px;--space-xl: 30px;\"><\/div><div class=\"header left  \"><h2 class=\"heading-3\" title=\"News\">News<\/h2><\/div>                <script type=\"text\/javascript\">\n                postSettings = {\n                    'categories': '80',\n                    'posttypes': 'post',\n                    'limit': '',\n                    'offset': '',\n                    'ignoresticky': '',\n                    'showsticky': '',\n                    'paging': '',\n                    'acfmeta': '',\n                    'order': 'desc',\n                    'orderby': 'date',\n                    'metakey': '',\n                    'metatype': '',\n                    'includeposts': '1788,4292,4307,4326',\n                    'excludeposts': '',\n                    'grid': 'col-lg-4 col-md-6 col-sm-12'\n                };\n                <\/script><div class=\"vc-loop-posts row\">    <div class=\"col-lg-4 col-md-6 col-sm-12\">\n\t\t<article class=\"WP_Post has-image vc-loop-news\" id=\"post-4281\">\n\t\t\t<div class=\"inner-article\">\n\t\t\t\t<a href=\"https:\/\/nersc.no\/en\/features\/surprising-findings-on-the-future-of-warming-in-the-arctic\/\" title=\"Surprising findings on the future of warming in the Arctic\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"678\" src=\"https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-1024x678.jpg\" class=\"attachment-large size-large wp-post-image\" alt=\"\" srcset=\"https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-1024x678.jpg 1024w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-300x199.jpg 300w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-768x508.jpg 768w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-1536x1017.jpg 1536w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-2048x1356.jpg 2048w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-520x344.jpg 520w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-800x530.jpg 800w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-1600x1059.jpg 1600w, https:\/\/nersc.no\/wp-content\/uploads\/2023\/09\/EspenStorheimNansensenteret_2020_CAATEX_cruise_EspenStorheim_0050-1920x1271.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/>\n\t\t\t\t\t<div class=\"text\">\n\t\t\t\t\t\t<span class=\"category features\">Features<\/span>\n\t\t\t\t\t    <h2 class=\"title\">Surprising findings on the future of warming in the Arctic<\/h2>\n\t\t\t\t\t    <div class=\"ingress\"><\/div>\n                    <\/div>\n                    <footer class=\"footer\">\n                        <div class=\"date\">7.
