Question #1 (5 points) If the formation of North Atlantic Deep Water stopped, what effect would it have on the circulation of the Gulf Stream How would this affect the air temperature (climate) in northern Europe (Sweden, Germany, United Kinglom, etc) Question #2(5 points) Elevated chlorophyll concentrations are found in the mixed layer along the coast of Oregon and Califormia, and in surface waters of the equatorial Pacific Ocean. Are these occurrences due to the same process, if so, how are they similar and different?Explanation / Answer
If formation of North Atleantic Deep water is stopped the gulf stream will not form which will reasult in even colder climate in the northern hemisphere.
North Atlantic Deep water is formed due to cooling of surface water travelling from equator which results in formation of ice and it makes water more saltier thus more dense. This then sinks and cool water is then transported to equators where it again warms due to evaporation and comes back on surface. This warm water then again is transported back to northern hemisphere via gulf stream which helps in warming the northern hemisphere.
If this cycle stops the average temperature of the northern hemisphere and countries along it will decrease and they will become even more colder. Also due to non availability of thermohaline gragient between northern and southern hemisphere gulf stream will also stop.
