EL Capital Improvement Request
Description of Requirement
PI Name: Nia Hurst
Branch: EL Wetlands and Coastal Ecology Branch
Date: 24 APR 2020
Quantity: 2 complete UGEMS and additional parts
ITEM/EQUIPMENT: U-Gust Erosion Microcosm System (UGEMS)
DESCRIPTION OF ITEM: The Gust Erosion Microcosm System (UGEMS) is a dual-core, flow-through erosional system that allows for real-time measurements of sediment erodibility, turbidity, and changes in water column nutrients (C, N, and P). The UGEMS provides in-situ environmental conditions in a controlled laboratory space, allowing multiple parameters to be evaluated at once. The system uses a spinning disk to create uniform flows across a sediment surface, allowing the generation of shear stresses ranging from 0.01-0.45 Pa in a 10cm core tube. The UGEMS is fully automated and can run continuously for days with minimum monitoring. The UGEMS can be used in the laboratory and also aboard research vessels, if necessary.
