I had a look at the IceBridge data, partly available from the recent
Quick Look product.
I downloaded the data of a few days of the Spring 2014 campaign, and loaded them into a spreadsheet to compute the average snow depth.
I computed an
average snow depth of about 15cm on the sea ice near the Beaufort Sea, while on the sea ice closer to the north of Greenland the average was closer to 30cm.
The data I downloaded were for 14, 17, 18, 21 March and 4 April. In the calculations I removed the invalid data; hopefully I calculated it correctly.
For example, the IceBridge flight on
21 March flew from Southeastern Beaufort Sea towards northern Greenland:
For that specific IceBridge flight (on 21 March), I computed an average of about 25cm snow depth on the sea ice. Splitting the data of that flight in 10 groups of equal size, resulted in the following 10 averages for snow depth on the sea ice, from west to east on the thick black line in the image above:
11cm, 16cm, 19cm, 18cm, 21cm, 25cm, 29cm, 30cm, 34cm, 36cm.
