Health authorities are investigating a fictitious disease, Fever B. The first case was observed in a 30-year old male. Marcus, who is an ecological scientist with routine occupational exposure to various areas in and around the Amazon River basin. Two months after returning from a 10-day trip to Bolivia, Marcus developed a high fever, a painful vesicular rash over about 30 percent of his body, and debilitating muscle aches and fatigue. He wasn't really himself until about 6 weeks after his early symptoms developed. He reported starting to feel weak and exhausted with mild aches about 2 days before the high fever and rash developed

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
