Figure 6. Map showing locations of sound velocity profiles (SVP) collected during survey operations in Red Brook Harbor, Massachussetts. Inset plots show SVP for casts six and eight. Plots display the speed of sound in the water column in meters per second on the x-axis versus water depth in meters on the y-axis.
