The Water Column Viewing Option is the primary 2D viewer for all of the water column related parameters as shown in Figure 1. The water column may be viewed by layer or by depth. For the former, the first options to set are the Layer Settings. There are three layering options for processing the water column data. They are Depth Avg for depth averaged results, Bot Layer for viewing the bottom active water column layer (this varies in the GVC model, standard sigma model this is layer 1) and a specified layer.
