- In many countries, irrigation is depleting aquifers to such an extent that land is subsiding, harvests are decreasing, and it is becoming necessary to drill wells deeper. In many cases, the withdrawal of groundwater has now greatly surpassed the aquifers’ rates of natural recharge. Discuss the possible consequences of this trend. What can society and science do to help alleviate this growing problem?The following table gives the total amounts of water and salt in the oceans and the total influx of water and salt from rivers each year. Use this information to calculate the residence time in the world ocean of both water and salt.Describe the characteristics of the California Current? What type of current is it? What type of current has the opposite characteristics and what are they? How does upwelling occur? What is the impact of upwelling on primary productivity? Why?
