Suspended Sediments in Lake Erie

Light-colored limestone sediments are suspended in Lake Erie in this natural-color image.

Lake Erie’s Long Point is outlined in turquoise in this natural-color satellite image. The pale color is likely due to limestone sediments in the shallow waters getting resuspended by a seiche or other disturbance. A seiche is a standing wave that forms in a partially- or fully-bounded body of water; in Lake Erie they are typically wind- and weather-driven. (Image credit: J.
