Background Paragraph: Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years. 
Story: John sailed across two oceans last year. First, he sailed across the Atlantic Ocean, which he noted as location A. Then he sailed across the Arctic Ocean, which he noted as location B. He was so amazed by the Arctic Ocean that he sailed across that ocean twice, time C and time D. Time C was in the summer,and time D was in the winter.
Which location would see higher salinity, location A or location B? Which location would see lower salinity, location A or location B? Which place would have higher evaporation, location A or location B? Which place would have lower evaporation, location A or location B? Which would have less ice cover, time C or time D? Which would have more ice cover, time C or time D? Would location A have lower or higher evaporation than location B? Would location A have lower or higher salinity than location B? Would location B have lower or higher evaporation than location A? Would location B have lower or higher salinity than location A?
