Problem 8

Examine and describe the ocean currents flowing in the Atlantic Ocean from the equator to the North Pole starting from Brazil $(60854.55 \mathrm{~S} 355824.09 \mathrm{~W})$. Do these currents reach the northern polar ice sheet? If the tropics become warmer, how would this affect the northern ice sheet?

Problem 9

Examine and describe the ocean currents flowing in the Pacific Ocean from the equator to the South Pole starting from Somalia (o $3232.23 \mathrm{~N} 44$ og $15.47 \mathrm{E}$ ). Do these currents reach the southern polar ice sheet? If the tropics become warmer, how would this affect the southern ice sheet?
