Current State of Sea Ice Cover | Earth - NASA
3 天之前 · Shown below are up-to-date satellite observations of the sea ice covers of both the Arctic and the Antarctic, along with comparisons with the historical satellite record of more than 4 decades.
Sea Ice Index Daily and Monthly Image Viewer
The daily Sea Ice Index provides a quick look at Antarctic-wide changes in sea ice. It provides consistently processed daily ice extent and concentration images and data since 1979.
Sea Ice Today - National Snow and Ice Data Center
Arctic climate warming continues to lead an unfortunate path of change for the planet. Here, NSIDC researchers summarize this year’s events in the Arctic, and touch upon Antarctica sea ice extent at the end of its austral winter.
Antarctic sea ice at near-record-low maximum extent for 2024
2024年10月3日 · Antarctic sea ice has likely reached its maximum extent for the year, at 17.16 million square kilometers (6.63 million square miles) on September 19, according to scientists at the National Snow and Ice Data Center (NSIDC) at …
Record low Antarctic sea ice coverage indicates a new sea ice ...
2023年9月13日 · Here, we show the confluence of Southern Ocean subsurface warming and record minima and suggest that ocean warming has played a role in pushing Antarctic sea ice into a new low-extent state.
World of Change: Antarctic Sea Ice - NASA Earth Observatory
2020年2月18日 · Antarctic sea ice peaks in September (the end of Southern Hemisphere winter) and usually retreats to a minimum in February. These image pairs show the average concentration of Antarctic sea ice for the month of September (left) and the following February (right) from September 1990 to February 2021.
Arctic and Antarctic Sea Ice Approached Historic Lows
5 天之前 · Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on September 11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline continues the decades-long trend of shrinking and thinning ice cover in the Arctic Ocean.
