Geostrophic Drag Coefficients over Sea Ice
The article of record as published may be found at http://dx.doi.org/10.3402/tellusa.v44i1.17118 The geostrophic drag coefficient, Cg = u*/G, and turning angle, α were measured October through November 1988 from a 120 km array of 6 drifting buoys and a drifting ship in the northern Barents Sea/Arcti...
