16. Velocity measurements on the Filchner/Ronne Ice Shelf (taken from http://nsidc.org) The velocity contours are from Vaughn and Jonas, 1996 (units of m/yr). (Vaughan, D.G., and M. Jonas, 1996. Measurements of velocity of Filchner-Ronne Ice Shelf. Filchner-Ronne Ice Shelf Programme (FRISP) Report No. 10. Ed. H Oerter. Pub. AWI, Bremerhaven. 111-116.)
