INVESTIGATION 3
Is Arctic Sea Ice Melting?
Arctic Sea Ice Extent. Image Source: NSIDC
The National Snow and Ice Data Center (NSIDC) compiles satellite and field observation datasets from NASA, NSF, NOAA, and other programs. With these data, they provide monthly updates on ice extent in both the northern and southern hemispheres. You will notice that the data begins in 1979. This is because satellite records only date back to that year. Read more about Arctic sea ice before satellites.
In this investigation, you will look at some of the NSIDC data to see how sea ice extent in the Arctic has changed over the last half century.
