Wind-driven surface currents (such as the Gulf Stream . the dose-response relationship is linear When scientists discover the existence of an emerging infectious disease such as SARS (severe acute respiratory syndrome), they must take immediate steps to determine the cause of the disease and the method of transmission. Sites on islands or coasts benefit from the moderating effect of the ocean and have "maritime" climates (like San Francisco). These winds help the atmosphere and ocean to move heat around the world. Being both cold AND salty makes it really dense, so it can sink very far.
