This graph displays the area of the minimum sea ice coverage each year from 1979 through 2016. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming could be amplified in the Arctic on account of ice … The volume of sea ice is declining for the 15 year period according to the data cited here. Sea Ice motion over the Arctic Basin.
Zoom in to any area on the chart by clicking and dragging your mouse. The sea ice cover is one of the key components of the polar climate system.

Satellite-based passive microwave images of the sea ice have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Monitoring Arctic sea ice and everything that influences it, as an extension of the Arctic Sea Ice Blog and the Arctic Sea Ice Forum, in order to increase awareness of Arctic sea ice loss. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming could be amplified in the Arctic on account of ice-albedo feedback. Search this site. Sea ice … Click image to animate. Each year, the extent line follows a similar path: … Adapted from NSIDC’s Charctic tool, the graph shows daily Arctic sea ice extent for every year since continuous satellite monitoring began in 1979. Sea ice concentration maps April 13th.

Perennial ice may have a life-span of nine years or more and represents the thickest component of the sea ice; perennial ice can grow up to four meters thick. We shall endeavour … The animated time series below shows the annual Arctic sea ice minimum since 1979, based on satellite observations. The Arctic Sea Ice Graphs web site. The graph above shows Arctic sea ice extent as of March 3, 2020, along with daily ice extent data for four previous years and the record low year. Arctic Sea Ice Graphs. One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. This graph shows the average monthly Arctic sea ice extent each September since 1979, derived from satellite observations. Concentration maps. Perennial ice may have a life-span of nine years or more and represents the thickest component of the sea ice; perennial ice … 2019 to 2020 is shown in blue, 2018 to 2019 in green, … Perennial sea ice, also known as multi-year ice, is the portion of the sea ice that survives the summer melt season. Evidence of the age of Arctic sea ice suggests that fewer patches of ice are persisting for multiple years (i.e., generally thick ice that has survived one or more melt seasons) (see Figure 2). The sea ice cover is one of the key components of the polar climate system. In addition here are some additional graphs and maps focussing on Arctic sea ice thickness and volume that are difficult to update automatically. One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. To see a corresponding daily sea ice concentration image, click on a line in the chart. Sea ice extent is derived from sea ice … Roll your cursor over the line to see daily sea ice extent values.
