Detailed Description

Imagine yourself in central Africa, in a dugout canoe crossing the lower Congo Rive''s rapids and whirlpools. USGS scientist John Shelton found himself there this past summer, measuring places where the waters reached a depth of over 700 feet. His measurements indicate that the Congo River is perhaps the deepest river in the world! This discovery was made during data collection to describe the River's conditions and understand its extraordinarily diverse richness of fish species. In this effort, Shelton worked with a team of scientists from the American Museum of Natural History.
