Current State of Sea Ice Cover | Earth - NASA
Oct 5, 2024 · Color-coded map of the daily sea ice concentration in the Northern Hemisphere for the indicated recent date along with the contours of the 15% edge during the years with the least extent of ice (in red) and the greatest extent of ice (in orange) during the period from November 1978 to the present.
Sea Ice Today - National Snow and Ice Data Center
Oct 3, 2024 · Sea ice loss has far-reaching effects on the planet because the ice helps regulate Earth’s climate, influences global weather patterns, and affects ocean circulations. Sea Ice Today began as a way to make sea ice science and analysis more relevant and accessible.
Sea Ice - NOAA Arctic
Arctic sea ice extent was similar to 2021 values, higher than many recent years, but much lower than the long-term average. Open water areas developed near the North Pole through much of the summer, making the area easier to access for polar class tourist and research vessels; both the Northern Sea Route and Northwest Passage largely opened.
Compare Maps of Arctic Sea Ice Extent Side-by-Side
The maps below show the extent of sea ice in the Northern Hemisphere around the North Pole. Select a month and year from the popup menus to compare two maps side-by-side. Try this: compare the sea ice in March and September for the same year. compare the sea ice in March for two different years.
Arctic Sea Ice Minimum | NASA Global Climate Change
Key Takeaway: Summer Arctic sea ice extent is shrinking by 12.2% per decade due to warmer temperatures. Arctic sea ice reaches its minimum extent (the area in which satellite sensors show individual pixels to be at least 15% covered in ice) each September.
Sea Ice Index Daily and Monthly Image Viewer
The area around the North Pole that is not imaged by the satellite is left out of the images (light grey circle). The daily Sea Ice Index provides a quick look at Arctic-wide changes in sea ice. It provides consistently processed daily ice extent and concentration images and data since 1979.
Arctic Sea Ice Forecasts: NOAA Physical Sciences Laboratory
Sea Ice Forecasts. These 0-10 day, experimental, sea ice forecasts are produced by the NOAA Physical Sciences Laboratory from a fully coupled ice-ocean-atmosphere model called CAFS. CAFS is run daily and posted online at 2 UTC.
Sea Ice - NOAA Arctic
The sea ice cover has long played a practical and cultural role in Indigenous communities of the north. Sea ice historically limited national and corporate activities in the Arctic, but decreased ice cover is influencing commercial transportation, resource extraction, and national security.
Arctic Change: Ice - Sea Ice - National Oceanic and Atmospheric ...
Sea ice shows up as various shades of grey and open ocean as blue. Each image is a snapshot of sea ice cover each day with the date shown in the lower part of each image. In general lighter shades of grey are newly formed first year ice and the …
Video: Annual Arctic Sea Ice Minimum 1979-2022 with Area Graph
Oct 3, 2022 · This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2022, with a graph overlay. In 2022, Arctic minimum sea ice coverage tied for 10th-lowest on record, extending a long-term downward trend.
