    Numerical Modeling of the Circulation of Wind-Driven Sediment Plumes In Large Lakes
    (2020-02) Carufel, Clay
    Strong winds blowing down the axis of southwestern Lake Superior in the springtime can produce a wind-driven sediment plume. The plume has coastal currents in the same direction as the wind stress and a balancing return flow that is driven by a pressure gradient into the open lake. Analytical developments suggest the return flow volume is determined by the wind stress on the channel and basin morphology. An idealized, three-dimensional model was developed in MITgcm to study this relationship. We find the modeled volume transport to be on the same order of magnitude as the analytical approach and to be dependent on wind stress, basin depth, and basin width. Realistic, three-dimensional models of Lake Superior and Lake Huron are developed to understand the relationship between wind stress on the lakes and the circulation driving wind-driven sediment plumes in them. We find that analytical estimates of volume transport are on the same order of magnitude as the realistic models and that the volume transport is linearly related to the wind stress.

    Peripheral Arterial Disease Diagnosis
    (2009-09-16) Lightbourne, Marissa
    Peripheral Arterial Disease is poor leg circulation. The patient can have discomfort or pain in their legs typically when walking or climbing stairs or skin changes. Without treatment, this can result in problems walking, loss of limbs such as toes, and in severe cases death. The pamphlet looks at how patients can tell if they are developing the disease.
