A global view of the Arctic on 21 September 2005. In support of International
Polar Year, a matching pair of images showing a global view of the Arctic and
Antarctic were generated in poster-size resolution. Both images are of
the same day, the date at which the sea ice was at its minimum extent in the
north. Shown in this view is all of North America and the northern portion of
South America. Image courtesy of NASA.
As climate warms and arctic ice retreats, both phytoplankton and shipping
interests exploit the newly opening waterways of
Canada's Northwest Passages. The Aqua/MODIS
data comprising the above composite image were collected during six consecutive
orbits of the sensor on July 26, 2019. At that same time a research cruise was
tracking changes in the pictured region (source NASA).
