Extensive floating marshes occur in a few locations around the world. Papyrus swamps of tropical Africa occur along the White Nile, the Okavango and Niger deltas, and along the shoreline of Lake Victoria. There are extensive Phragmites swamps in the Danube Delta in Romania. Seasonal and permanent floating meadows are found in the middle Amazon flood plain.

Proxy data such as tree rings, ice cores, and microorganisms are collected and analyzed by scientists to unlock past climate records stretching back thousands to millions of years ago.  This video podcast examines how scientists can decipher past climate from such records by focusing on a proxy calibration study in the Gulf of Mexico.  Microfossils recover

This video clip was captured from a boat while collecting water quality samples on  the White River on April 20th, 2011.  The gage height at the time was 17.39* feet and discharge was 32,900* cubic feet per second.  The conditions seen here are considered bank full, which is the point at which the flow of the river completely fills river channel.&nbsp
