noasL and a fairly broad ice belL along the south coast as far as

Hcykj anes. On considering the l ast sixty years, it will be seen Lhat the period

I D20-39 includes 17 A-years, 3 B-years, 0 C-years, altogethrr 17 months with ire I D00- 19 - 8 - 10 - 2 - 4.8 I HH0-99 - 2 - 12 - 6 - - G7

This shows that despite all the variations in the individual years, n consLant improvement of the i ce conditions around Iceland has taken pl ace since the culmination of the heavy ice years at the beginning of the <'ighLies of the l ast cenLury, the breadth of the ice belt having constant ly dre rrased from Lhis time to the presenL.

The lee between 65° N. lat. and Kap Farvel.

AR sLaLed above, Lhe ice changes its character in the area between l1 ·P la11d and Lhe Angmagssalik disLricL. The chief cause of t his is that Klig lrl,l y norLh of ()5° N. laL. Lhe drift i ce meeLs the westward-moving I r111i11 gw C111·1·c11t., which forces Lhe norLh-i:;outh-moving Polar Current w<•sLwnJ'(I, and large ice masses melL where Lhc Lwo currenLs meeL.
