Biological sampling devices are deployed on the upper Mississippi River to collect invertebrates for science. Each sampler is attached to a floating buoy and multiple samplers are placed together near a wing dam structure on the river to study the river's food web and productivity.

Distribution and Controls Over Habitat and Food Web Structures and Processes in Great Lakes Estuaries
Rivermouth ecosystems, or freshwater estuaries, are the focus of human and wildlife interactions with the Great Lakes. They are highly valued as the region’s urban, industrial, shipping and recreational centers; and home to recreational harbors, wildlife viewing and production, beaches and urban riverfronts. Rivermouths are also both the mixing zones where nutrients from upstream watersheds are...
River Productivity
Biological production represents the total amount of living material (biomass) that was produced during a defined period of time. This production is important because some of it is used for food and some is valued for recreation, it is a direct measure of total ecosystem processes, and it sustains biological diversity. Production is a measure of energy flow, and is therefore a natural currency for...
