Visualize sea ice extent (area of ocean with at least 15 percent sea ice concentration) data for the Arctic and Antarctic. View and compare sea ice extent data for any year or any combination of years from 1979 to present (including near-real-time daily data).
2 dni temu · Analyze monthly-averaged or daily sea ice extent and concentration via interactive maps. Plot monthly ice extent anomalies, map sea ice concentration anomalies, and more.
4 lut 2020 · The graph below shows the onshore arrival and departure of polar bears on Baffin Island relative to dates of sea ice advance and retreat. Sea ice has been breaking up earlier in the spring over the years (green) and is forming later in the fall (blue).
28 sty 2021 · With ice-free summers looming, gaining access to preferred den locations and their favorite prey is becoming increasingly difficult. Observations taken by the Environmental Monitoring of Svalbard and Jan Mayen show the correlation between sea ice decline and polar bear den counts over the years.
30 paź 2024 · Color-coded map of the daily sea ice concentration in the Southern 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.
25 lut 2022 · Polar bears are experiencing and responding to them in different ways and at different rates depending on what part of the Arctic they inhabit. Here we take a look at how polar bears are responding to sea-ice changes across seven different regions.
Polar bears roam across the circumpolar Arctic, where they rely on sea ice to reach their seal prey. But not all sea ice is equal. Learn about the four sea ice ecoregions, how the quality of sea ice differs across the polar bear’s range, and how we can help ensure the bears’ future by addressing climate change.
