1. The vertical profile of oxygen is measured in a shallow (h = 1 m) quiescent pool (velocity is zero) as shown in the plot below. The distribution of O₂ is uniform in the horizontal direction so that it can be described as a 1D distribution C₀₂(z, t). A. Sketch the corresponding profile for the flux of O₂. For points 2-5, describe in words the direction of the flux. Then, based on the plot, argue whether the oxygen concentration at those locations will increase, decrease or stay the same after a small increment in time. You may assume there are no sources or sinks within the water column. The image presents a graph with two axes. The vertical axis is labeled \( z \), and the horizontal axis is labeled \( C_{O_2} \). The graph depicts a curve with six marked points, labeled from 1 to 6, connected by a line. The curve starts at the top right and follows a path downward to the left, with different slopes between points:1. **Point 1** is at the top right.2. **Point 2** follows a slightly downward sloping path.3. **Point 3** continues downward.4. **Point 4** forms a noticeable curve to the left.5. **Point 5** continues downward.6. **Point 6** reaches the bottom left.The horizontal axis extends from 0 to \(-h\) at the bottom, suggesting a measure related to depth or altitude, while \( C_{O_2} \) likely refers to the concentration of CO\(_2\). The graph likely illustrates how CO\(_2\) concentration varies with depth (\( z \)).
