Researchers measure stream velocity, while placing decomposition strips

Researchers measures dissolved oxygen consumed by microbes on a decomposition strip and collect stream invertebrates with a Surber sampler.

Researchers measure stream pH, conductivity, turbidity, and dissolved oxygen using a multi-parameter water quality meter

Researchers rinse off a decomposition strip with ethanol to halt decomposition and collect stream invertebrates with a Surber sampler.

A strand of cotton strips is buried under the leaf litter at the edge of the stream and will be used to measure riparian soil decomposition rates

A temperature sensor is anchored to a stone and will be placed in the stream to measure water temperature over time

Cotton strips are placed into blackout containers and incubated in the stream for two hours. Dissolved oxygen readings are then taken as a metric to measure metabolism in the tubes
