"For example, a drop in pressure can cause tiny particles of sediment and other 
material to float off the bottom or rise higher in the water column than they 
normally suspend-particularly when currents are involved-slightly reducing 
water clarity.  but more  importantly, it can affect tiny creatures such as 
zooplankton and phytoplankton-the building blocks of any respectable aquatic 
food chain."
