McMurdo Dry Valleys Streamflow and hyporheic thermal regimes influence on hyporheic storage and exchange at Von Guerard Stream, 2006

We describe the modeling data created and used to study the influence of stream and hyporheic thermal regimes on hyporheic storage and exchange, as well as the field data used in the study. Models and methodologies are also described, along with the physical details of the data. In streams, such as those in the McMurdo Dry Valleys, that experience large daily fluctuations in temperature, associated changes in water density and dynamic viscosity could affect hyporheic characteristics.  Figure: Longitudinal view of stream and hyporheic temperatures at each of the 11 temperature proble locations at two different times. One time, 8:30, was in the middle of the cool morning experiment, the second time, 15:00 was in the middle of the warm afternoon experiment.  Open circles represent stream temperatures. Filled diamonds, squares, and triangles represent temperatures at 5, 10, and 20 cm depths below the streambed surface, respectively本研究详述了为探究河流与潜流带（hyporheic zone）热状况对潜流储集与交换的影响而构建并使用的模拟数据，以及本研究中采用的野外观测数据。同时，本研究还对相关模型、研究方法以及数据的物理细节进行了说明。在诸如麦克默多干谷（McMurdo Dry Valleys）内的河流这类存在显著日温度波动的水体中，水体密度与动力粘度的相应变化可能会对潜流带特性造成影响。**附图**：两个不同时间点下，11个温度探头（temperature probe）布设位置处的河流与潜流带温度纵向视图。其中8:30为低温晨间实验的中期阶段，15:00为高温午后实验的中期阶段。空心圆点代表河流水温；实心菱形、正方形与三角形分别对应河床表层以下5 cm、10 cm及20 cm深度处的潜流带水温。
