Monitor from which Laura Cottrell is able to trigger the Niskin bottles to "fire", hence collecting the water samples. Each red line running horizontally across the screen is a spot where water was collected. The other lines on the screen indicate temperature and salinity measurements. By their shape, it is easy to see that both temperature and salinity start out much higher at the top of the water column, and decrease quite rapidly down into the water column.
